[Rostock MAX] Z-Direction Issues

[Kiro]

Having some trouble with my Rostock MAX.

Regardless of what I set my Z_HOME_POS to in configuration.h or Printable Height in Repetier, any G-Code input for the Z-direction causes the extruder to crash into the bed. For example, say my Z_HOME_POS was set to 345 and I homed it with the command "G28". The command "G1 Z50 F1200" as mentioned in the Rostock MAX Assembly Guide does not stop it 50mm above the bed, but rather it continues and hits the bed. I've tried changing Z_HOME_POS to 100 and this still occurs. This remains true for STL files sliced with Slic3r. However, the manual controls in Repetier do work properly. The X- and Y- directions do not have this problem.

I am using Repetier-Host V0.85b and Arduino 0023 from the RoSoft Installer (http://download.seemecnc.com/RoSoft.msi), and Marlin for v1.0 RAMBo controllers (though I've also tried the firmware included in the RoSoft Installer). I don't know if it matters, but I had to invert my X, Y, and Z directions in configuration.h. I have not tried the Repetier firmware yet, but that's next on my list.

The file you downloaded has a version of Repetier that is meant for the delta style printer. Generic Marlin will not work for a delta. Either use the one you have downloaded already or use polygonhell's.

Didn't realize another firmware existed. I'll check it out and see if anything changes. Thanks.

Edit:

Updated using the Repetier firmware found here: https://github.com/seemecnc/RepetierMAX ... master.zip

Works fine now with steps/mm set to 53.33. I will need to fine-tune things and get the calibration and Slic3r settings right, but that's a non-issue.
