Nozzle height too high #73

Open LeandroSQ opened 2 weeks ago

LeandroSQ commented 2 weeks ago

Hello, I've been trying to calibrate my Eddy, using it as endstop and without the Z-Offset config.

When the nozzle is touching the bed, Eddy is 2mm from the bed surface I ran LDC_CALIBRATE_DRIVE_CURRENT CHIP=btt_eddy with Eddy 20mm from surface. And running PROBE_EDDY_CURRENT_CALIBRATE_AUTO CHIP=btt_eddy (Manual does not work too) results in the nozzle being to high, unable to print.

I also did the temperature calibration, as I have the USB variant.

On the paper calibration, tried several times and all of them seem to result in the same issue.

same problem but nozzle too low in my case and I can't calibrate manually.

@bigtreetech any ideas on how we can calibrate this?

bigtreetech commented 2 weeks ago

Completely clear out anything probe related from the automatically generated section. This includes all thermal offsets, z offsets, mesh settings, drive current, etc... start fresh.

Run the calibration, then run the thermal calibration and then see what happens. Should be good. Also, why did you choose not to use the z-offset out of interest?

As the guide mentioned Z offset was not needed due to the nature of Eddy, I decided not to go with the an offset config, seemed a lot simpler as well.

Thank you for the instructions, will try later and let you know how it goes.
