Delta Printer Z-Probe not looking right
I've been away for a while but I now have a set of FSRs mounted with the FSR Endstop Controller.
I've got everything setup I think but here's exactly what I'm running.
FSR/FSR Endstop Controller from TriDPrinting
Repetier 0.91 Rev 8 Firmware
To clear any questions about the machine not being setup correctly, this printer has been running for months without FSRs and I just wanted to add them to increase first layer precision. I can confirm that no motors are skipping, the printer is calibrated completely, and the print surface is not THAT far out of skew.
So here's where I'm at:
I verified that the probe is 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:15.00 X:0.00 Y:60.00
12:52:50.458 : Z-probe:28.11 X:-50.00 Y:-27.00
12:52:52.223 : Z-probe:28.18 X:50.00 Y:-27.00
12:52:52.755 : Z-probe average height:23.76
In EEPROM Settings I have Z-probe height = 15.000, Max. z-probe - bed dist. = 0.000.
Why does the first probe show 15, but the other two probings show 28.11 and 28.18 and how does this affect the plane that is being created with the 3 probings? I know that this would generate a very skewed plane, but does repetier not care about that offset?
I also tried setting EEPROM to Z-probe height = 0.000, Max. z-probe - bed dist. = 0.000 and got the following from a G29 command.
20:13:49.254 : Z-probe:0.00 X:0.00 Y:60.00
20:13:50.478 : Z-probe:12.92 X:-50.00 Y:-27.00
20:13:52.260 : Z-probe:13.76 X:50.00 Y:-27.00
20:13:52.817 : Z-probe average height:8.89
