Cant probe z axis



  • So I tore apart my anet a8 that I had running for 2 years on a duetwifi. I built a new I3 frame with a 280x280x300 print area. Adjusted congfig file to adjust for 0,9 degreee nema 17 steppers. I got it all up and running and then updated firmware and webserver but know when I when I home all, X and Y zero properly but when I probe with my Differential IR probe I get an Error: Z probe was not triggered during probing move. The z axis goes down about 50 mill and then stops and gives me error. If I add M564 S0 it works fine and can probe the z access, but I dont want to run that all the time/ attached are my config bed and Homeall files if anyone could please help me out. I have read just everything trying to figure out what is wrong.

  • You don't have anything in homeall to actually probe the bed as far as I can see.

    It moves Z 10mm up to get out of the way and then there is no G30 afterwards to probe. Did it get cut off when you copy and pasted? or is it actually not there?

    If it's not there, just add G30 after the X Y moves to position the probe so that it can get your Z height.



  • Sorry Yes they G30 is at the very end. It did get cut off



  • So I figured it out. In the Home all the First G1 with the H1 in it. For some reason it worked before but doesnt allow the z axis to go below the zero set at power up. But I can home all axis now. Funny how you miss stuff til you post with a problem
