Zero First Layer Issues - FIXED

@Lion

so any more input would be appreciated.

This thread is a continuation of

Z-Offset is not saved

While the eddie current sensor is real good, I cannot get a perfect first layer on the full bed surface, unless I adjust Z-Offset. Doing so, my first layer is absolutely top notch, on all 150x150mm. But whatever I do, either via Mainsail (Klipper WebUI) by clicking on the SAVE and SAVE_CONFIG buttons, or via the small display of the Zero via End-Save Z-Offset, doesn’t get stored in the EEPROM / doesn’t survive a power cycle or a reboot. Is there any other way to save the Z-Offset in EEPROM, so…

Where can I get the older config with the pressure sensor?

Hi, Love my Zero so far, but I would like to see how the pressure sensor was used. I can only find the latest firmware and software for the Zero. Does anyone know where I can find the previous versions of the Zero software ?

Pressure based VS eddy NG type tap to zero

I’m going to spin this off of the existing thread Sovol has changed their tap to zero method to no longer use the pressure sensor. In fact the latest printer.cfg doesn’t even define the pins for the pressure sensor. The eddy is now defined as 2 different probes: [probe_eddy_current eddy] sensor_type: ldc1612 z_offset: 3.5 i2c_mcu: extruder_mcu i2c_bus: i2c2 x_offset: -19.8 y_offset: -0.75 vir_contact_speed: 3.0 [z_offset_calibration] non_contact_probe: probe_eddy_current eddy contact_probe…

Also read back through the Zero channel at the Sovol Discord. Many folks trying to improve the nozzle clean routine.
