@printthatthing the printer doesnt know where z 0 is, a G30 is missing. G30 uses the bltouch to set it. Call G30 after x and y endstop setting, but before G1 Z0

After the G90 in most cases x and y are moved to the middle of the bed, then G30

@JoergS5 I get it a try tomorrow. Thank you for all help.

@printthatthing the
G1 H1 Z-355 F360
should be a replacement for what I proposed (the G30 proposal), but 355 is less than the 500 height of M208, so 0 may not be reached, I would set it higher to Z-600.
And the G92 Z0 is not needed, because the G1 H1 Z... already sets Z to the M208 minimum for Z, ie 0.
The sensitivity setting G31 P is probably wrong, please set P25 instead.

Thank you all again. I think I have it running now.
I had to keep ! for duex.pwm5 else it does not probe.

Is the heatmap very bad or ok to use without adjustments?

dc42

As you have no DueX, you are not connecting the servo pin of the BLTouch duex.pwm5, so you should not use that selection in configtool or config.g. Use the name of the actual pin that you have connected it to, which is exp.heater7, and don't invert it. Although as it happens, using duex.pwm5 and inverting it will work.

printthatthing

@dc42 Aha, okay that make sense.

Phaedrux

@dc42 said in RRF Config Mapping:

so you should not use that selection in configtool

Unfortunately the config tool currently doesn't show the expansion pins right now, just duex pins.

@printthatthing said in RRF Config Mapping:

That's a bit of a saddle shape for sure. You may or may not be able to fix that physically. You can test the effect of the compensation by printing a bed test like this: bedlevel_nozzle_0.4_200x200-0.3-0.8.stl

printthatthing

@Phaedrux Ok thanks.

Now I'm stuck with error at bed heating.
Error: Heater 0 fault: temperature rising much more slowly than the expected 1.7°C/sec
Duet 2 Wifi power a solid state relay for a 220v heater.

I executed M307 H0 S90
M307 H0 results in below.
Heater 0 model: gain 340.0, time constant 140.0, dead time 5.5, max PWM 1.00, calibration voltage 0.0, mode bang-bang

Then I tried to save the value
M307 H0 A340 C140 D5.5 V0 B0
But it result in
Warning: M307: Heater 0 appears to be over-powered. If left on at full power, its temperature is predicted to reach 365C

Phaedrux

That's expected. The warning is letting you know what the max uncontrolled temp could be.

printthatthing

@Phaedrux Ok, but I still not able to heat the bed. It start heating but halt after few seconds. Error: Heater 0 fault: temperature rising much more slowly than the expected 1.7°C/sec

Phaedrux

Are you sure you saved the PID tuning results with M500? Do you also have an M501 at the end of config.g to load the saved results?

printthatthing

@Phaedrux i was missing M501 in config.g
Restarted boad but getting same error when trying to heat bed.
Tried to run M307 H0 S90 again but it fails with Error: M307: bad model parameters

Phaedrux

In config.g change M307 H0 B1 S1.00 to B0

Then delete your config-override.g and run M307 H0 S90 again after a reboot. Then save with M500.

Phaedrux

Also make sure you're starting from a cold bed state.

Yes of course.
