Marlin 2.bf - G76 - Probe temp. compensation error (no replies)

Hey there,

I just dug out my Wanhao Duplicator I3 and did a few upgrades including SKR 1.4, TMC 2130 SPI and an inductive Z-probe.

It auto levels and prints fine but now I wanted to add temperature compensation for the probe by adding a thermistor. I installed a new thermistor to my probe using thermal compound and capton tape and set it up succesfully in Marlin 2.0 Bugfix. It compiled fine and the FW outputs the correct temp values for Probe Temp in addition to Nozzle and Bed temp.

When I run G76 I always get the same error, no matter what settings I apply for "park pos" and "probe pos".

Send: G76
Recv: !Probe position unreachable - aborting

My probe-nozzle offsets are set correct and I have no idea what else to try.

Configs are attached.


#define PTC_MAX_BED_TEMP 110

// Park position to wait for probe cooldown
#define PTC_PARK_POS_X 50.0F
#define PTC_PARK_POS_Y 50.0F
#define PTC_PARK_POS_Z 100.0F

// Probe position to probe and wait for probe to reach target temperature
#define PTC_PROBE_POS_X 90.0F
#define PTC_PROBE_POS_Y 100.0F

I already changed the values here but nothing changes. Homing before and after doesnt help either.
