When I use Auto-Home on my k8400 only the Y-Motor moves.
When using the move axis command, the Y axis moves perfectly but the x and z axis dont move at all.
Motor whine is noticable.
Printerhead can be moved by hand in the Y Axis whin in move axis, but not in the X axis where it is impossible to move.
Bump
I take is it’s your first test after building the printer? If you can’t move the X axis by hand then it’s not set correctly. have a look at the Wiki.
For the Z axis, did you check if the linear bearings were moving freely? Sometimes you can have a bad one missing a ball or two.
When the printer is turned off I can move the X-Axis but as soon as I turn the printer on I start to hear motor whine and the X axis becomes immovable.
Same with the Z-Axis
Update: Problem found, I swapped out the 1.5A Driverboards and through trial and error, found out that 2 of them were broken.
Did you check the reference voltage on the not functioning stepper drivers?
How? (sry am new to this)
[quote=“alex2141”]How? (sry am new to this)[/quote]It’s explained at the end of the manual but you’ll find a better procedure here.
Checked all the voltages and they were all around 0.9 - 0.92 V
[quote=“alex2141”]Checked all the voltages and they were all around 0.9 - 0.92 V[/quote]Ok It won’t help, these are correct.
After swapping the drivers your X Y and Z axis are functioning correctly now? And the extruder motors don’t? In that case you’ll have to ask for replacements. Be patient it’s easter holiday. You’ll have to wait till Tuesday for an answer.
I posted another post about my extruder motor specifically.
The motor works if I connect to the x Motor port on the Motherboard, so the Mobo itself has to be the problem. However this is already my 2. Mobo and on the last one I had the same Problem so I have a feeling that it has to be something different, since the chance that 2 Mobos have the same problem is rather slim…
If I remember well the extruder won’t turn if the printhead is cold.
