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
