I know you shouldn't buy anything until I have the design finished but i have been offered 3 X AM882 drives for £110 would this be a good buy and work well for this machine, With my knowledge off electrics not great i want to keep the electrics as simple as possible .After reading some more build logs am i right in thinking that 1610 ballscrews all round would be ok for this machine with Nema 23 Stepper Motor 3Nm all round or Nema 23 Stepper Motor 4Nm?
Cheers Greg
