Bed height map problem

Hello guys, I'm new to the 3D printing world. I have a He3D delta K200 printer and I'm trying to calibrate it, I'm following the video tutorial, but I can't get the bed height map thing working, neither the correction matrix. When I try to measure the bed height map, I get a couple of 0, the problem is that my printer is moving more than it should. For example if I set the X to 50 and -50, the printer moves up to 70 on the X axis, so maybe that's why I get some 0, how can I fix this?


  • Your steps per mm seem to be too high if you get such a difference. The Bed height map only works for repetier-firmware, so check if that is on your printer if you use it. Also always have a good look at the log so you see what is going on. You need to start height map when you are close to bed but not triggering with z probe. Also coordinates need to be inside the bed circle and be reachable with z probe (which does this with added z probe offset)
  • I think the problem is the printer not getting right what x:0 and y:0 is. This is the values I get from trying to do the bed height map.
