Use this script to transfer any 3D model to spline and then generate GCode out of it.
you can view demo video here for the milling https://youtu.be/iRbLDFfGRTc
Parameters Explaination:
Driller Size: this indecate the size of the cutting bit in mm, this used to configure the width of the pathes Moving speed: this to configure the GCode to move the head with mm/s speed Driller speed: if your driller (spindle) uses TTL to control it's speed -M command- this you could configure the driller to rotate at that speed (RPM).
For laser cut CNC i'll upload another video shortly
