(Edited for hopefully more clarity) I was surfacing my spoilboard when my LongMill 48x30 MK2.5 suddenly stopped moving on the X-axis. The motor just makes a clicking sound, as if it’s binding.
Here’s what I’ve tried so far:
Motor swap test: I swapped the X and Z stepper motors. The Z-axis (using the old X motor) worked fine, but the X-axis (using the old Z motor) still just clicked.
Cable check: I swapped the X and Z motor ports on the Super LongBoard (SLB) to verify it wasn’t a cable or motor issue. The issue followed the X-axis port — any motor plugged into that port doesn’t move and only clicks.
Based on these tests, it seems like the X-axis port on the SLB might have failed. Could this be an SLB hardware issue, or is there something that could be reset or reconfigured in gSender to fix it? Please help.
@sfontana976 I’m confused. You say that when you plugged the x axis port on the SLB into the Z motor, it worked. However, then you say that anything you plug into the x axis port does not work. Those two things contradict each other to me.
Sorry for the confusion. The x axis will not work no matter what motor is plugged into it. At first I thought it was the motor but the motor works it I move to the z axis. If I put the z axis motor on the x axis that one will not work. Hoping this makes more sense. Its like something if wrong with the x axis port on the SLB or Gsender. I uninstalled gsender and installed the most recent version but no go.
I am not talking about the motor binding. I am talking about the x axis being bound up.
It’s as simple as trying to turn the x axis lead screw by hand. Best do that with the mill off so there is no holding current on the motors. Does the carriage move FREELY from one end to the other end.
The x axis is not bound. For these tests I disconnected the lead screw from the moter. Before disconnecting from lead screw I was able to move it with my hand turning the lead screw without issue.
The X motor plugged into the X axis cable with no load does not turn.
The X motor plugged into the Z axis cable with no load (motor disconnected from lead screw) turns.
If you flip connectors between Z and X axis on the SLB (so the Z axis is powered by the X axis system) , the Z axis does not work but the X axis works.
If I have that right then I would think there is an issue with the X axis system on the SLB (assuming I have thunk through this correctly)
