cncjs VS FreeCAD

I believe the Tool Change command is supported by: gSender or cncjs.

Get a raspberry pi, https://www.raspberrypi.org/, throw UGS https://winder.github.io/ugs_website/ or cnc.js https://cnc.js.org/ on it.

I use https://cnc.js.org/ to send g-code to the machine, this uses web page interface to set up the machine.

CNCjs - For CNC, same as above but for my CNC router, though I would never trust my CNC to run when I'm not physically close by ha ha so this hasn't been exposed to my OpenZiti network.

I think cncjs is what you're looking for: https://cnc.js.org/

Can you try with a different gcode sender software (cncjs), to see if you can Reset (red button) and Unlock (orange button)?

6 - Alternative, Save the gcode and use a g-code sender (example: cncjs). Notice: a g-code sender needs to know where is the 0,0 position/the start position, so in LightBurn select the start position "Current Position" and select the appropriate Job Origin. Save the gcode. On cncjs, move the laser to the "Job Origin" and zero both X and Y (the icon after the + on the Work Position). Click the blue Upload G-Code button, select your file and press the Play button to start the job.

Software: bCNC, cncjs, a couple others

bug reports should be made on the github issue tracker here: https://github.com/FreeCAD/FreeCAD/issues

FreeCAD is a general-purpose parametric 3D computer-aided design (CAD) modeler. This open-source software application is based on C, C++, and Python. PVS-Studio doesn't support Python at the moment, so I will only check the C and C++ parts. Here is the link to the project code.

LibreCAD, OpenSCAD (more script based and more for solids), FreeCAD.

would freecad be an option?

Hi! 3d printers read .stl files, generally. You can design your own files for free with FreeCAD in a relatively simple format before sending them to your slicer and printer. Out of personal experience, design a silicone component into your mold, as the hard plastic is unforgiving when de-molding. Good luck!

Second Way: I don't use this second method as the first one already works for me. However, you can download FreeCAD, which is an OpenSourced Free to use software for many hobbyists. I personally think it's slightly trickier to get used to but it works! You can watch this video to model a nose cone in FreeCAD.
