I’ve got a persistent issue with my z-stepper motors. They can’t lift the router. If I position the router half way along the Y-axis, no problem. Position the router at either extremity of the Y-axis, and the weight bearing stepper just skips.
Troubleshooting so far:
First, I checked for free movement at both Y-plates with the coupler removed. Free and easy movement.
Second, connected the couplers to the motors, but no power. Free and easy movement.
Third, chacked no physical impediments, snagging etc. None.
Fourth, fitted two new NEMA17 high torque ( 92 in/lbs) steppers. No change.
So now I’m thinking this is either a cabling issue or a firmware issue. The cabling is from Ryan. Connected as per instructions, and all directions etc work as advertised.
Firmware? I seem to recall someone else talking about this issue, and he solved it via firmware fixes, but I cant now find his post.
Any help will gratefully be accepted.
My final avenue is to use Nema23 stepper motors for the Z-axis, but I know this involves all sorts of stuff I don’t know anything about.
