I have recently setup a custom made cartesian printer. I have upgraded from ramps to the Duet3 mini 5+ wifi board. I am having an issue with a couple of things the moment but they seem to revolve around the setup for the end stops.
I am using mechanical switch enstops for X & Y and BL Touch on Z
X enstop is set to Min
Y to Max
Z to Min
So when they are homed the head is in the upper left corner.
I am finding that when the axis are homed on the Duet Web Control Y is reading as 0 instead of 410 (seeing it is at its max in the Y axis) this is causing issues as the machine wants to move past the end stop.
Once X is homed to 0 it only moves right or in a positive direction if I instruct it to move in a negative direction.
I used the RRF configtool to set the machine up and there seems to be no safety built into stopping the machine from wanting to push past the end stops. once homed it seems to be happy to try to move past them.
The Z axis seems to work fine at the moment.
Any help would be fantastic.
