Hi everyone, I recently installed the Duet 2 wifi board on my Modix Big-60 with a CR Touch (metal pin) and everything seems to be working fine. The X and Y endstops are located on the left in the back and the printer homes X, Y and Z as it should. However.. when I slice a print in Cura 4.8.0 or Simplify3D, the printer homes in the back left as expected and then rushes and crashes into the front. In order to make everything work I had to switch the X and Y on the board. To eliminate the problem I removed everything except G28 from the start-Gcode in Cura. Below my config.g, homeall.g, and everything else which could be of importance. Many thanks in advance for any input which could solve my problem. I'm getting an Akismet Spam error when trying to post so placing it all in a text file.

@jay_s_uk thanks a lot

@jay_s_uk
how do i do that

The Z axis home'd properly one week ago, but not anymore.
The BL touch itself is good, and i cannot remember remotely touching it in the config.
I don't know what to do, please help.

thank you @droftarts , the Y axis indeed had the wrong amount of teeth

@Phaedrux
the prints i tried to make we're meant to be circular, instead they came out oval. so i tried scaling the axis but later i figured out the Y axis didn't fully cover the bed. the Y axis was scaled properly but the same as the X axis but it could only do it well if i said the bed was 3~ times as long.

I don't know whether this is a software of hardware problem, 'cos we've already replaced the motors, and now we're trying to remove the mistakes from the config.g

i am having a lots of problems with prints coming out in the wrong shape and the bed axis limits seems wrong but i can move the head all over the bed now butt stil the prints are miss shaped. are there any obvious mistakes

@phaedrux Thanks for your suggestions! Will try them out and get back to you with the results.

@alankilian No actually homing goes ok. After homing the X and Y positions are both 0.0. After a G1 command both axes move in the right direction as well.
