Hello All,

It is a bit like ImplicitCad in that it has a server back end -but- it
also has a client front end.
I have seen a few people have a go at this but none of them were quite
doing what I needed or had some core implementation problems.
I've gone after some of those and tried to resolve them.
I'd love to get some feedback and would be happy to help answer any

That is a great question!
That number of 90% is based on having worked through the OpenSCAD
documentation from the top to the bottom. What isn't currently supported is
the import/export options or text.
But that number needs a whole lot of unit tests and to be documented and
that is exactly what I am doing at the moment. Also saying something is
supported and verifying that it is stable and unit tested is NOT THE SAME
THING and I appreciate that.
What made this possible ( for those interested ) was putting together a
transpiler rather than shifting the whole yacc grammar. That was an option I
considered but it is so pretty much welded in to the c++ code. .
However a lot of complication with the grammar and the yacc melted away by
going down the transpile path and then what was left is a core of basic
geometrical operations all of which have been straight forward to implement.
Note also that a lot of complication like interactions with the GoldFeather
and the OpenCSG have been done away with.
You can get some idea of where I am up to by playing with the demonstration
client also.

Hi there Mixotricha,
I was quite excited but I tried to copy-paste 3 Openscad files of sharply decreasing complexity, and none of them would produce an object, or even an error.
When I refreshed the page, I couldn't get back to the original example file that first greeted me - so maybe a browser caching issue?
There seem to be a lot of people starting projects to re-create OpenSCAD, in their own way, and none is anything like as compatible as I would need them to be for them to be useful. Even OpenJSCAD and FreeCAD rarely open one of my designs from OpenSCAD...
For example, supporting 'minkowski' is an absolute must, intersections, linear extrudes, logic and ideally text functions - some way to handle fonts could complicate this but it would be worth it! How would we call a function from a separate file? That sort of thing...
Cheers
Alex

Hi Alex,
If you can please attach examples of what did not work and I will get busy
doozering on them to sort it out!
At the moment the road map is to do exactly this. Get feedback. Push in
OpenSCAD examples in.
Rinse repeat and keep doing it until it conforms.
In terms of the longer road map you can expect me to keep working on it
well in to the future.
Also it is going to need more robustness in the parser. Some things still
break it like the user defined functions.
All these things are in the parser but it still has bugs that need to be
ironed out.
Thank you for trying out the Makertron and providing some constructive
feedback :)

When I try to drag with the right mouse, the image shifts to the right
NO MATTER WHICH WAY I DRAG THE MOUSE. I am using a Wacom tablet rather

(NetFlix fails miserably).
No idea what to do once the object appears on the screen: I don't see an
Export button to allow me to save an STL.
Interesting. Exactly why would I use it rather than OpenSCAD? That is,
what is/are the advantage(s)?

Just a request… could you consider making your software recognise British English spellings? IE color=colour… I speak 4 languages, 5 if you include English (United States) but am always getting told off by OpenSCAD for spelling things ‘correctly’ from my POV!
I am sure other actual languages would love their own versions, that could get hard to manage, but this would be simple!

Hi Alex,
Thanks for that. I can see that I have missed out a few different
combinations of values for input in to the transpiler. I did not pick up on
tohse while working through examples in the OpenSCAD documentation. Also I
can fix it so it understands colour and color and center and centre and
also 'r' when we mean 'radius' and 'radius' when mean 'r' and 'h' when we
mean 'height' and so on. Those ones always bug me and they are on my to-do
list.
Doozering mode has been activated!

Hi Alex,
Thanks for that. I can see that I did not pick up on a few different
parsing formats for input in to the transpiler. I have been following
through examples in the documentation but I see some differences. Also I am
bugged by colour/color and 'center' and 'centre' and so on. That has been
on my to-do list for awhile.
Doozering mode activated!

Just a request… could you consider making your software recognise British
English spellings? IE color=colour… I speak 4 languages, 5 if you include
English (United States) but am always getting told off by OpenSCAD for
spelling things ‘correctly’ from my POV!
I am sure other actual languages would love their own versions, that could
get hard to manage, but this would be simple!
Cheers

Hi Alex,
If you can please attach examples of what did not work and I will get busy
doozering on them to sort it out!
At the moment the road map is to do exactly this. Get feedback. Push in
OpenSCAD examples in.
Rinse repeat and keep doing it until it conforms.
In terms of the longer road map you can expect me to keep working on it
well in to the future.
Also it is going to need more robustness in the parser. Some things still
break it like the user defined functions.
All these things are in the parser but it still has bugs that need to be
ironed out.
Thank you for trying out the Makertron and providing some constructive
feedback :)

Can you share anything about your roadmap/next priorities?

Hi there Mixotricha,
I was quite excited but I tried to copy-paste 3 Openscad files of sharply
decreasing complexity, and none of them would produce an object, or even an
error.
When I refreshed the page, I couldn't get back to the original example
file that first greeted me - so maybe a browser caching issue?
There seem to be a lot of people starting projects to re-create OpenSCAD,
in their own way, and none is anything like as compatible as I would need
them to be for them to be useful. Even OpenJSCAD and FreeCAD rarely open
one of my designs from OpenSCAD...
For example, supporting 'minkowski' is an absolute must, intersections,
linear extrudes, logic and ideally text functions - some way to handle
fonts could complicate this but it would be worth it! How would we call a
function from a separate file? That sort of thing...

After spending a few years on the "OpenSCAD 2" project, my experience is
that creating a new language implementation with 100% backwards
compatibility with OpenSCAD is an extreme technical challenge, and I
eventually abandoned it as a goal. The problem is that the language is so
full of quirks that are not found in any other language, many of which are
undocumented. For one thing, the scoping rules are so weird that you can't
"transpile" OpenSCAD into a conventional language or compile into VM code
for a conventional language, and preserve the semantics.
In my opinion, the practical way to achieve full backwards compatibility is
to use the existing OpenSCAD interpreter to compile an OpenSCAD script into
a CSG tree, then write a back end that processes that CSG tree.
Mixotricha's approach leads to an OpenSCAD-like language that isn't fully
backwards compatible. You won't be able to take arbitrary OpenSCAD scripts
off Thingiverse or whatever and expect them to just work without being
"ported" to MakerTron. However, if you are writing new code from scratch,
then you should be able to write code that is portable between OpenSCAD and
MakerTron.
The first example I tried was:
cylinder(r=1,h=5,$fs=6);
This is the OpenSCAD idiom for a hexagonal prism. What I got instead was a
cylinder with a circular cross section.
I also tried
x = 1;
function x(a) = a + 1;
module x(a) cube(x(x));
x(2);
but I didn't get a result back, and lost contact with the makertron server.

to use the existing OpenSCAD interpreter to compile an OpenSCAD script into

If you are interested my previous work on this did exactly that. It is in
my humbaba tree. I went through this. Putting a socket layer on OpenSCAD is
trivial. Building it in to a shared library so I could access it through
nodeJS also trivial. But then what you will find is issues with speed and
the complex pathway for multiple rendering targets. The roadblock that
emerged was interaction between a client side interface in something like
react and dealing with the OpenCSG/Goldfeather approach. Making OpenSCAD
headless is not hard. But the rest of it will rapidly lead you to a series
of painful roadblocks. I've got a better way. Think transpiler. Not parser.
The examples you have given above are excellent and also things that can be
fixed. I've had the client up live for one day and this sort of input is
exactly what I needed. Keep them coming.

I also forgot to say also that having made the OpenSCAD headless it brings
one to thinking about moving the parser as a whole. After all the grammar
is already provided. But as I am sure you know ( and as is often the case
with any grammar ) moving the OpenSCAD grammar as it currently stands to a
new target is not at all trivial. So I changed my thinking. Don't write a
parser. Write a transpiler. Everything OpenSCAD does results in a stack of
geometrical operations. You can get to those operations via a transpile.
You can also address quirks in a really powerful way in a transpile. The
example I would give of that is the lazy OpenSCAD closure.

I'm having difficulty following you; we may be using terminology
differently.
OpenSCAD proceses a script using the following steps:
- the parser converts the script to a parse tree
- the evaluator converts the parse tree to a CSG tree
- the renderer converts the CSG tree to the final product. OpenSCAD has a
previewer that uses OpenCSG, and a mesh generator that uses CGAL. You can
also dump the CSG tree as text (a simplified OpenSCAD script), without
further processing.
A transpiler is basically a compiler that converts source code in one
language to source code in another language. A transpiler will always have
a parser as the first step of processing. So I don't know what you
mean by "Don't
write a parser. Write a transpiler."
In OpenSCAD, the parser is not very difficult to write. But it is extremely
difficult to transpile OpenSCAD into another language without first using
the OpenSCAD evaluator to construct a CSG tree. That's because of the very
unusual dynamic scoping rules used by the evaluator. Within a function or
module, the meaning of an identifier is only known at run time. A
transpiler would either interpret identifiers using static scoping rules,
which doesn't work, or it would have to transpile into another language
that uses the exact same dynamic scoping rules (which aren't documented,
and which I never fully succeeded in reverse engineering.) What you want to
do is transpile the CSG tree into your final format. The CSG tree also has
OpenSCAD syntax, but it's a subset that eliminates all of the hard
problems, so you can feed that into your existing transpiler.

If you are interested my previous work on this did exactly that. It is in
my humbaba tree. I went through this. Putting a socket layer on OpenSCAD is
trivial. Building it in to a shared library so I could access it through
nodeJS also trivial. But then what you will find is issues with speed and
the complex pathway for multiple rendering targets. The roadblock that
emerged was interaction between a client side interface in something like
react and dealing with the OpenCSG/Goldfeather approach. Making OpenSCAD
headless is not hard. But the rest of it will rapidly lead you to a series
of painful roadblocks. I've got a better way. Think transpiler. Not parser.
The examples you have given above are excellent and also things that can be
fixed. I've had the client up live for one day and this sort of input is
exactly what I needed. Keep them coming.

After spending a few years on the "OpenSCAD 2" project, my experience is
that creating a new language implementation with 100% backwards
compatibility with OpenSCAD is an extreme technical challenge, and I
eventually abandoned it as a goal. The problem is that the language is so
full of quirks that are not found in any other language, many of which are
undocumented. For one thing, the scoping rules are so weird that you can't
"transpile" OpenSCAD into a conventional language or compile into VM code
for a conventional language, and preserve the semantics.
In my opinion, the practical way to achieve full backwards compatibility
is to use the existing OpenSCAD interpreter to compile an OpenSCAD script
into a CSG tree, then write a back end that processes that CSG tree.
Mixotricha's approach leads to an OpenSCAD-like language that isn't
fully backwards compatible. You won't be able to take arbitrary OpenSCAD
scripts off Thingiverse or whatever and expect them to just work without
being "ported" to MakerTron. However, if you are writing new code from
scratch, then you should be able to write code that is portable between
OpenSCAD and MakerTron.
The first example I tried was:
cylinder(r=1,h=5,$fs=6);
This is the OpenSCAD idiom for a hexagonal prism. What I got instead was
a cylinder with a circular cross section.
I also tried
x = 1;
function x(a) = a + 1;
module x(a) cube(x(x));
x(2);
but I didn't get a result back, and lost contact with the makertron
server.

Hi there Mixotricha,
I was quite excited but I tried to copy-paste 3 Openscad files of
sharply decreasing complexity, and none of them would produce an object, or
even an error.
When I refreshed the page, I couldn't get back to the original example
file that first greeted me - so maybe a browser caching issue?
There seem to be a lot of people starting projects to re-create
OpenSCAD, in their own way, and none is anything like as compatible as I
would need them to be for them to be useful. Even OpenJSCAD and FreeCAD
rarely open one of my designs from OpenSCAD...
For example, supporting 'minkowski' is an absolute must, intersections,
linear extrudes, logic and ideally text functions - some way to handle
fonts could complicate this but it would be worth it! How would we call a
function from a separate file? That sort of thing...
Cheers

Hello All,
I'd like to announce Makertron.
http://makertron.io http://makertron.io
It is an alternative I am working on that addresses some of problems I
see with OpenSCAD and with OpenJSCAD.
It is a bit like ImplicitCad in that it has a server back end -but- it
also has a client front end.
I have seen a few people have a go at this but none of them were quite
doing what I needed or had some core implementation problems.
I've gone after some of those and tried to resolve them.
I'd love to get some feedback and would be happy to help answer any
questions about my project.

On github it says:
Lastly the OpenSCAD parser while supporting an excellent CSG language
( though in some areas ambiguous ) is so glued to the interface and
supporting code that it is hard for the language to evolve or move
forwards from that interface. It is our opinion that this effort has
stalled and something new needed to be developed to address these
issues.
If that's one of the core premises, I'd suggest to have a look at
http://apidesign.org/
Also it would be interesting to have a look at that geometry engine
(quote "The Makertron server supports its own internal geometry
engine based on a BREP representation.") which seems to be based on
Open Cascade. I can only find shared libs in the server repo.
ciao,

Hi Alex,
I pushed a new update out today with some improved argument parsing. I see
that nice little example you gave now loads. I'll be sorting out some sort
of supported features matrix and a time line as well. Just a lot to get
done :)

everything just disappears to the bottom right, no way to get it back.

Hi Carsten,
I've tested it in Firefox and Chrome. It works fine in those but I have not
checked it in Edge.
I would suggest that if it is getting the grid and axis the trouble is
perhaps with talking to the server.
The client opens a port to the server ( using socket.io ) on port 3000.
You can test the server by going to : http://makertron.io:3000
If it is up and responding it should give you a version number back.
"Makertron server version 5.0"
If not take a look in your console/debug window and if you see any
interesting error messages let me know.

Hi Damian,
Pleased to confirm the change you made works for me – first time I have seen it make something of mine and it’s great that you updated it so fast, so I am encouraged to throw more things at it and try to break it again J
Before I go deep – can I ask if you can elaborate on protection of intellectual property pasted into this box? IF you’re taking this to any serious level, people will want to know what happens to their designs – I for one would be keen to clarify.
Also, in the vein of preparing for success, would you be able to make this in the form of an ‘embeddable widget’? It would be amazing if I could use this sort of thing to edit models and push them to a page on my website, for example, so people can see the latest tweaks!
I can confirm the left-button-pan works, and right-button-move only goes down-right for me too. Chrome on Windows 7.

Hi Mark,
Leaks are very bad!
Was this in Chrome or Firefox or Edge?
I'll go investigate.
What will really help with a lot of this is when the OffscreenCanvas
feature becomes available.
Being able to put the rendering pipe inside a worker is a must-have.
Also I once knew a Mark Schafer that worked at RH in New Zealand? Fond
memories of those days.... !

This is such a great forum. This is some wonderful feedback I am getting.
One of the things about the Makertron is that both the client and server
components are docker ready.
So if you are in a locked down environment you can pull both the server
and client and build both the client and server image and deploy them
locally in to a docker.
Instructions are in the github documentation to do this but are by no means
complete!

I pushed a new update out today with some improved argument parsing. I see that nice little example you gave now loads. I'll be sorting out some sort of supported features matrix and a time line as well. Just a lot to get done :)

On github it says:
Lastly the OpenSCAD parser while supporting an excellent CSG language
( though in some areas ambiguous ) is so glued to the interface and
supporting code that it is hard for the language to evolve or move
forwards from that interface. It is our opinion that this effort has
stalled and something new needed to be developed to address these
issues.
If that's one of the core premises, I'd suggest to have a look at
http://apidesign.org/
Also it would be interesting to have a look at that geometry engine
(quote "The Makertron server supports its own internal geometry
engine based on a BREP representation.") which seems to be based on
Open Cascade. I can only find shared libs in the server repo.
ciao,
Torsten.

Final idea, and I think it could be amazing if you did it, and really help get traction:
Have you considered making this a plugin for OctoPrint? (Defninitely to include OctoPi)?
This would instantly enable a lot of people to host it on a Raspberry Pi 3 server.
I would love to be able to edit SCAD and just send that to my printer server – so efficient!
There is already a slicing engine, CURA, available as a plugin – maximum score if you could integrate with that too!
Cheers
Alex

This is such a great forum. This is some wonderful feedback I am getting.
One of the things about the Makertron is that both the client and server components are docker ready.
So if you are in a locked down environment you can pull both the server and client and build both the client and server image and deploy them locally in to a docker.
Instructions are in the github documentation to do this but are by no means complete!

Requiring port 3000 is a no-no on this network. The page loads with http://makertron.io but not with http://makertron.io:3000. When loading with http://makertron.io, clicking Generate provides no response at all (multiple tries).
The port issue appears to prohibit any further trials on this network.

Where is the source code for the OpenCasCade/BREP interaction? You refer
to
https://www.opencascade.com/doc/occt-6.7.0/overview/html/occt_brep_format.html
in the github client readme.md and I was interested in the
OpenCasCade/BREP, but could not find anything in either the client or
server github repositories. Can you point to the surce code where
interaction with with OpenCasCade is taking place?
I am on Windows here, it isn't clear to me if makertron builds under
Windows and I don't have the time to investigate. Instead I will try
makertron.io a bit more from home where the port 3000 issue probably
does not apply.

Alex,
Yes! I've had this on a beagle bone with MachineKit ( but -not- in the
docker containers in the current deployment). I was attempting to do just
that. Send SCAD straight to the Beagle Bone which has a copy of Machinekit
and the Replicape board plugged in to it.
