Hello
I have completed the assembly of MPCNC and plan to use it as a router.
However, on the crown-test, some problems started.
“Repetier” with pleasure lifts the Z-axis upwards to any given values.
Down he does not always lower it. Approximately 80% of the commands for moving the Z axis down are simply ignored.
When we try to draw a crown, we see devilry.
The axes move chaotically.
It seems that the X axis periodically thinks that it is the Y axis.
The Z axis for some reason only moves upwards. Moreover, it moves with every turn higher and higher.
The problem is repeated on the versions ReptierHost 1.6 - 2.0 - 2.1
WinXP, Arduino 1.85, Marlin 1.1x
Can you move the Z axis all the way up and down very easily with your fingers just twisting the coupler?
I really doubt re-flashing the board will change anything, I also strongly feel you should try everything before you do that. Can you put up some pictures of your build and wiring. maybe what size steppers you bought, what voltage you set the drivers to? All that is much more likely to be the issue. If you just work with me here we will go in order of common issues. A video of the problem will also help.
Are you using a leadscrew or a Allthread?
Have you seen the troubleshooting questions at the sticky post on the top of this forum?
So the red flag I am actually seeing here is I am fairly certain you do not have my firmware. Your repetier host says your extruder is at 11.6C. That is not correct for either what I receive the boards with or what I ship them with so somehow you have something else on there.
