I have a 4x4 standard cnc router from cncrouterparts.com and I cannot get the motors to have movement. This is the link to the electronics kit with the 3/8" motors: http://www.cncrouterparts.com/4-drive-diy-nema-23-electronics-kit-p-75.html I cant figure out if its a wiring issue or an issue with how I set up mach 3. Although, the limit switches are working fine. Any tips, help, etc?? Thank you!!
