The FreeCad drafting desktop has been improving ... and the other

I use AutoDesk's "Fusion360". It's free for most of us. Of course it
will open AutoDesk's DXF file format.
AutoDesk has gone a 180 degree turn on pricing making a premiere CAD/CAM
program free. Fusion360 should be popular with anyone doing CNC work.
It allows one to make 3D models and then ca

LinuxCNC handles that. No need to zero the counts.

I like this idea a lot, I've been thinking along similar lines. I don't
understand why every CNC controller uses 10x increments.

I have several brandsĀ of MCU with Arduino being one. I am wondering if anyone
on the list has tried a Parallax Propeller for any cnc type app. It ha 8 - 32

You just make a sketch on one plane. Using it this way it is just like any
other CAD program.Bu

That is an odd thing to say because Arduino is moving to ARM.
Tool chains used to be such a big deal. Mostly what you'd be inves
If you have to use on chip peripherals such as DMA, ADC, or PWM you very

the silicon manufacturer implementation.) An Arduino OS will sield you
