Stepper drives and power supply I got off Ebay, type in stepper drive and look for a bloke called Yuntat from Hong Kong, 4.2 amp will do but I got the 5.6 amp drives. The power supply is the 0-50v 10 amp from him. Although I'm presenty using a power supply made up from bits off the old denford mother board. Any help you need let me know, got your private message, not sure what electronics came with the machine, send me some pictures and I can identify what you have and have not.
