Faulty Z stepper
-
Hi
I purchased a Duet Ethernet and received it yesterday 31/5
I purchased the Duet to replace a Replicape board so all wiring has been tested and working the Replicape was working when I took it out.
anyway log onto the duet web page all looked good checked endstops to make sure they were triggering .
so next I thought I would try home ….finger on the power button in case motors going wrong direction ...click home and there was a crack hit the mains power off button and thought that cant be good.
double triple check wiring even tho I had already triple checked before first power up ...cant see anything wrong.
power up again all seems good logon to web all looks good tried home again this time only 2 axis moving and a message coming up drive 2 shorted to ground.
It was configured as a delta printer so drive 2 is Z ...I think the crack I heard was the Z stepper having a issue.
The Z stepper is broken ....I verified it was not stepper motor as I can put the z motor on Y and it will move .any help is appreciated
thanks

Is there any visible sign of damage to the Z stepper driver chip?
-
yeah it looks like a small crack
-
it is very small but the surface does look difference to the other chips.
I have remapped Z to E1 using M584 X0 Y1 Z4 E3:5:6:7:8:9 and it homes properly so no doubt there is a issue with the Z stepper -
has there been a issue with this happening or am I just damn unlucky ?
-
A small number of driver chips seem to suffer from infant mortality. Please ask your supplier for a replacement board.
