I’m slowly getting stuff together to someday start building my own CO2 laser cutter.
(got 100W laser tube + PSU and a 50mm lens) So I’m now looking into driving systems and controller boards. I would like to keep as much open source as possible.
I’m planning to use the laser cutter for lots of different things. Cutting things like my fingers is one of them of course ;), but I’m also hoping to use it for very small smd pcb engraving+etching techniques. So I would need very high precision to create pcb traces.
I’m following ODrive for some time now, but I’m unsure yet if it would be good enough to be a better option then using plain old stepper motors. I would like the extra speed, but I’m unsure about the precision.
Are there already other projects using the ODrive with CNC like applications? I have read some problems with stepper code conversions. But I’m not really up to date with if these are already fixed.
Can someone share there opinion on using ODrive Servo’s instead of stepper motors for a CO2 laser cutter with a 60cm by 90cm bed?
