Z Axis Stepper End Play

LowRider CNC Advice
1

Hello,

Currently building an LR4 - my steppers (Stepperonline 17HS19-200451) have approx 1mm of sprung endplay. Obviously not an issue with X or Y but does this need controlling/limiting with the Z-axis?

I can’t answer definitively as I’m running an MPCNC Burly, but I feel as though the weight of the Lowrider Z axis will be greater than the springiness of the steppers, so it shouldn’t be a problem.

You’re probably correct but decided to add a thrust bearing between coupler and motor body
