I am retrofitting an older router and as always there came up the challenge of making the whole system reliable and as little susceptible to issues with noise as possible.
I decided to go with AXBB-E controller and iSV57T integrated servo motors from Stepperonline (very similar to iHSV57 integrated servos from JMC).
Servo manual: https://www.omc-stepperonline.com/download/iSV57T.pdf
Unfortunately AXBB-E doesn't have differential outputs for step/dir signals and I assume that running a single ended signal through a 4 meter long drag chain that is already packed with other cables (inductive proximity sensors, spindle and motor power cables) will cause issues.
Should I go with a single ended to differential module or what would be the most optimal and reliable solution?
