FSR Auto Level not working

vf1010

I've been struggling to get it to work ..Mini Kossel + Repetier 0.91 firmware + Ramps 1.4 + FSR (3) + FSR Endstop Controller. The printer has been running for months without FSRs. The motors are not skipping, the printer is calibrated and the print surface is close to level. I verified that the FSR's are working correctly with G31 and can measure the distance with G30. When I run a G29 on the three points this is what I see: 12:52:49.224 : Z-probe:5.00 X:0.00 Y:60.00 or any value I set as max z probe bed dist 12:52:50.458 : Z-probe:8.12 X:-50.00 Y:-27.00 12:52:52.223 : Z-probe:8.18 X:50.00 Y:-27.00 12:52:52.755 : Z-probe average height:7.1 the average height being calculated is skewed causing the nozzle to be 5 to 15 mm above the print surface Any help or suggestions will be appreciated. See Configuration.h below

Thanks

Please upgrade to 0.92 first. It has so many fixes that I don't search in old versions for solutions. I'm using 0.92 on my delta with autoleveling so I know it works there.

Does repetier only support logic level endstops? or also FSR which in nature are varying voltage?

Repetier

Only logic level. So for FSR you need a hardware converter to switch digital pin. Analog reading is much too slow.
