Newbie looking at 6040 (China CNC) for polypropylene 15mm sheet

Ignore stepper voltage ratings. As you say, the stepper driver effectively pulses the drive voltage; the driver manages the current rather than voltage but the higher voltage allows higher current pulses which helps develop torque. Confused me at first but the stepper driver will have an adjustable current setting which is more useful. That's also why you use a linear power supply - better current pulse capability.

Thought it was along that line.


As for picking what steppers to get.
Higher amp rating, higher holding torque are what to look out for?

The drivers; http://www.zappautomation.co.uk/elec...ion/em806.html
Looks to be the best at the £100-120 option.
80V and 8.2A.



Wondering what controller to get too..
