I'm slowly collecting parts to convert my Sieg X2 to CNC.
I've ordered the stepper motors and controllers from Zapp, so no matching problems. The question is - is screened cable necessary to connect the motors to the controllers (4 core bipolar parallel). Working in the electronics industry, I know (a little) about noise in electronics. What I've seen on the you-tube sites, this is not used, or is it taken for granted? Has anyone got views, or experience on this?
