Can't change z min pos
repetier server 1.4.8 - Hephaestus-76
repetier host v2.3.1
I have an old Davinici printer (yea I know) that I had to replace the nozzle on. Since no OEM parts are available, I had to use an aftermarket part. I have to change the z min position.
I am currently using a serial connection. I was able to send an M205 command to verify a response from the printer. I can modify the Z settings in EEPROM(z min pos and z probe height), and I can see them send in the log, but when I hit Z home, it ignores my Z new min, which I'm guessing will create substantial problems when I try to calibrate in the future.
Is the Z position not being written correctly to the firmware? Or is there another setting I need to change?
It also sounds like you have a z probe and if you home using z probe you should keep z min at 0. Only z probe height needs to be adjusted to new distance and all should be ok. Use the eeprom editor in server to change the setting. M205 will just show while M206 sets it, but you also must save it to eeprom to make it permanent which the editor takes care of.
Check M119 output and if it gives output for z max that is the case. What you need to do in that case is just increase z height by 10 mm.
z probe height is in case you have a sensor on extruder to measure bed distance. Do you have that at all? Cause there would be gcode to measure z height from this as well. Only for that case adjusting z probe height would help as the probing than changes z height.
z max length = 200
z probe height = .540, changed to 26
max z probe - bed dist. (negative value?) = 5

Now if extruder is 10mm longer the z probe height reduces 10mm which is I guess not possible if the sign changes! Probe must trigger before hitting bed with nozzle. If that does not happen you must lower z probe to make it work again. Only then calibration can work at all. Wonder why you can home at all at the moment if this is the case.
If you have a physical z endstop and not using probe for homing zou must change trigger height so it triggers 10mm earlier. You can add a extra move after homing to adjust z after that triggered but z should not trigger during printing so that would only be ok if you trigger lower than noyyle level and need to go up for z=0.
Are you using this
which is the only reptier based DaVinci solution I know of? From this all have a z probe
The original DaVinci is not using our firmware. This is only when someone hacked it to use that firmware.
Not sure if we are thinking the same for pin numbers. I thought we were talking about correct pin number and these are in configuration.h file not in any registry. They must match the hardware connected so if z probe is connected to pin 63 it is ok - my comment wa smore that this is the value used in explaination and is likely different for the davinci printer.
If you just want to check if the pin is high or low send
to query end stop state. It shows the state of configured end stops.
