Veti,
Thanks for the reply. I have use dc42's backlash macro and added the codes to do the same test in the Y direction. It has worked very well and I use it often, especially after mods and/or cleaning. the SD/m in the x direct is 0.005 and nan. In the Y direction is 0.006 and nan.
The problem with the reporting error is gone now. I backed up my sd card and did a reset on the board. Kind of harsh, but I needed to get back in production. The DWC now reports head position at -0.15 and the firmware message reports Stopped at -0.151. Not much for the reason why the problem appeared, but it fixed the problem.
Thanks again.
