v-chonk: does not return to xy safe-home location before homing z
Next steps; any suggestions?
BTW, there is another V-chonk builder with the same issue as I have... 03Julian04, in "chonk homing" thread.

Yes. They both work the same way... can't tell any difference.

Yes, homing Z is in the center and works well with the superpinda. home_x and home_y do not work. G28 x

v-chonk: does not return to xy safe-home location before homing z
@MDFPereira : I am now able to successfully home after changing the home_xy_position to 0,90, rather that 90,90. This works from both the buttons and G28.
I don't know if this will work when printing, but at least now I can start tuning. I appreciate your help. Thank you.

v-chonk: does not return to xy safe-home location before homing z
An update. Today I started a fresh install with a new SD card. RatOS setup wizard completed successfully.. no strange stuff. So, no mods of any kind in the finshed firmware. The behavior was as described previously. As you said... wierd!

v-chonk: does not return to xy safe-home location before homing z
Homing by the buttons does work except the carriage stays at location 0,0 while homing z which defeats the proximity sensor. If I recenter the carriage after homing X and Y, when I home Z the carriage moves back to 0,0 before the activating the z drive.
Thank you for notes….

v-chonk: does not return to xy safe-home location before homing z
Thank you! Your help is much appreciated. One question: DEBUG is reporting the following during homing macros: "Run Current: 1.09A Hold Current: 1.09A" , Is this correct? I thought that there should be 0 holding current when doing sensorless homing, true? It seems G28 Y and G0 Y90 do not work when this message is given.

MDFPereira... thank you for the suggestion. Tried modifying printer.cfg as suggested but it didn't make any difference in behavior. I don't know if this is helpful, but here are some other observations. 1) HOME_X, HOME_Y does not move the carriage. The debug information indicates expected values for the parameters, and both macros get called recursively 4 times. HOME_Z also does not move the carriage, and is called recursively. 2) The home buttons on mainsail seem to work correctly, except that the carriage is in the wrong position when Z raises toward the sensor. 3). G28 {X, Y or Z} has the same behavior as the buttons.

"Must home Axis first" When trying to home after fresh 2.0.2 Install
I am having an issue with homing on a v-chonk, RatOS V2.1 RC3. When homing z the tool head stays at
location 0,0, which puts the superpinda sensor off the bed. Since the sensor can't trigger, the bed crashes into the hotend. I would have thought all axes would return to safe_home_z postion after homing.
