A while back, Alex posted a video setting up an Xtool RA2 rotary on a co2 laser. To make sure I did it right ,I bought a stepper driver, connected it to my raspberry pie test setup ,set current for 1 amp and ran it for 45 minutes. The motor stayed cool .
@bandsawking Well I have had to replace 2 if them. I have some on a CNC plasma, Make sure to use shielded cable if you run plasma. Or keep the control cables away from the plasma cutter. I even have a No-HF pilot arc torch. Still got 2 of my TB6600s. But like you said, they are cheap enough.
@chargepositif The one in the picture is a rpi with a protoneer hat running grbl. It works great. I have another with linuxcnc on a rpi but I struggle with it.
