z correction probe NAN?

edited February 2016 in Repetier-Firmware
Hey guys, I have a mini kossel setup with a repetier firmware I configured on the site about a month ago (cant get the exact version right now as im printing) I have the printer calibrated pretty well, but wanted to use zprobe bed leveling still. I took a design that puts the FSRs in the effector and tweaked it a bit. I have its output going to a small arduino that is flipping a digital output high when the FSRs get to a certain point. Everything seems to work fine, except the log shows me this..

the zprobe always reports NAN, if I do a M114 without pressure on the print head I get "L" and if I put some preasure on it I get "H" so it seems to work.. what would make it report NAN?

This is my start G-Code in Slic3r
M140 S[first_layer_bed_temperature] ; Bed (no wait)
M104 S[first_layer_temperature] ; Extruder (no wait)
G90 ; set absolute coordinates
G28 ; home all axis
M190 S[first_layer_bed_temperature] ; Bed (wait)
M109 S[first_layer_temperature] ; Extruder (wait)
G29
M117 Start
M300 s1000 p400 ; Beep
M300 s1500 p400
M300 s2000 p400
M300 s2500 p400
G92 E0 ; reset extrusion distance
M117 Printing

    It adds values like bed coating or bending correction. So please check your eeprom, I think that one of these values has a Nan value.
  • ShreddinPBShreddinPB
    I checked my settings, and found the one for bed coating which was 0.0, so I canged that to 0.001 just to make sure it has a value, but I can not find the bending correction setting in the firmware, whats it called?

  • ShreddinPBShreddinPB
    I should say, I cant find it in the eeprom settings
  • ShreddinPBShreddinPB
    I see them in the firmware tho and they are all 0
  • RepetierRepetier
    Just had an other user (or was it you) on github with a similar problem. Reason was that the 3 probe points in eeprom were on a line so they did not span a plane causing the error. Is that here the case.
  • ShreddinPBShreddinPB
    Yes! That is it, I never bothered to set that since I think I am using the advanced bed probing, where it probes about 20 points
