This doesn't look all OK. The minus sign is a bit misplaced.
Also, I don't understand why you show the bed.g macro when talking about homing Z (G28 Z). Z must be homed before you can run bed leveling.
G28 Z when called is executing the homez.g macro to home z.
G32 (bed leveling) is calling the bed.g macro when leveling the bed or quad gantry leveling as with the Voron 2.4.
G29 (bed mesh) is calling the mesh.g to create a bed mesh to compensato for an uneven bed or bent gantry. -
@gixxerfast so my z home has to be off an estop. I cant use a specific point on the bed with the probe. Im not trying to be a pest i am trying to learn
-
@frnknstn No problem.
No you can home with a probe. You just config it in homez.g and in homeall.g (I just call homez.g in my homeall.g).
I just don't understand what the problem is right now.
Can you home all axis?
What printer did you have now again?
-
@frnknstn Don't get frustrated. Just do one thing at the time.
Fix the Z-homing first, then move on
-
@gixxerfast i have been trying to figure this out on my own so i wasnt bothering people. but for some reason i think i keep making it worse.
I am kind of running a voron2.4, i am running the voron gantry style with Duet3 6hc and expansion
I installed a z stop thinking i was suppose to use that then the bed levels from that setting. but i keep reading i dont need a z endstop. So im not sure. I am really trying to learn this but i think someone telling what to do and why its that way is the only way it seems i can comprehend this stuff. -
@frnknstn i can home x and y. when i tell it to home z it starts probing, when thats complete i get errors

@frnknstn i am trying to go by these and adjust them
