Hey guys, has anyone thought on using closed loop stepper and drivers for theY and X at least for the MR1? Would the main control board accept the closed loop feedback?
I have used them in the past on my DIY CNC lathe with an Centroid ACORN board and I would say is a bit piece of mind knowing that you will not loose steps in a long project.
Any feedback is appreciated.
I was thinking the same thing, i cant afford the Clearpath option at this point but was looking at Stepperonline (EBay) nema 23 180 watt motor. Clough42 on Youtube did a video on them. I think it could be a good option but i’m no expert on the subject. I was thinking of just changing out the X axis motor first. Im guessing its pretty much plug and play after tuning the motor. Would need a power supply for the new motor.

I may do that later down the road and convert to linux cnc. I’m still deciding if I should use a linear encoder which I think would be the best solution with existing steppers, or to add encoders to the end of the x and y axis nuts, or go with new steppers with embedded encoders. I really like having closed loop control if something goes wrong and also don’t need to re-home and lose accurate position if something does…
I think the ac-servo drive encoders are also available through the pins. This will be useful to get feedback of actual speed.
Still just trying to get my spindle working as it has resonance issues.
