Re: strange arc error

lol, I moved that object 1mm to the right and it looks fine now, moved back and it remained fine; I guess the recompute fixed things

strange arc error

The attached file works almost perfectly, until GRBL stops with > G2 X256.7519 Y189.0722 Z-4.0000 I-305.4642 J7.0490 F900.00 (line=3191) error:33 (Invalid gcode ID:33) error:33 (Invalid gcode ID:33) (error 33 is GRBL's way of saying it's an invalid arc), and the rendering shows something fishy in th...

Re: Start Points and order in face based toolpaths

not sure this is the right thread, but... I got some time to build things again, Path has improved a lot in the mean time, but one thing is unchanged Screenshot from 2019-03-14 21-32-18.png since I had something more important to do, I dug into it a little and found a way to use my old code that sur...

Re: Post for MPCNC with Marlin firmware

For my MPCNC I am using GRBL with cncjs; the only notable differences from a CAM point of view might be G0 / G1 (I don't know how Ryan's hacked version handles things, but in stock Marlin G0 is an alias for G1, so you'd need to add an F parameter to get any movement for rapids)

Re: FC v0.17dev: Part Design Next Usecases and Best practices

TIL. thanks, I didn't notice it, I was using the UI and that one doesn't have expression support. ... and it is a bit buggy or PEBKAC (complains about incompatible units when I try to link it to an angle constraint), but this is offtopic, my questions were about the compatibility of my workflow wit...

Re: FC v0.17dev: Part Design Next Usecases and Best practices

A clone that only exposes some parameters would probably be ideal, and the closest thing you'd get to either openscad modules or the OOP paradigm (instance of a class with some public properties and the rest of the implementation hidden - I guess the terminology will be less familiar to non-programm...

Re: FC v0.17dev: Part Design Next Usecases and Best practices

You have the pattern operations in Part Design. They can repeat features in a linear or polar arrangement. doesn't help in this case, as far as I can tell, because linear and polar arrays (and the other operations) duplicate the object in various ways what I was looking for was a way to treat a bod...

Re: FC v0.17dev: Part Design Next Usecases and Best practices

Since this topic is about best practices, and I'm self taught in these matters: how frowned upon is it to, say, name a sketch "master" or something along the lines of this, name the constraints for use in formulas, and also use the sketch afterwards? I've been using spreadsheets in the past, but usi...

Re: Help on a simple socket/pocket

just for the record, edge profile would also work, you just have to change "On" to "Left" or "Right", depending on the direction of movement (just pick one and see if it's where it should, otherwise pick the other one). re. contour - for some reason it doesn't seem to lift the tool at the end of the...
