Triple Z G28/G32 homing error
-
Hello,
I'm having trouble setting up my printer to do auto bed levelling. It is a custom corexy machine using 3 individual Z motors and a bltouch as Zprobe.I can run M28 X, M28 Y and M28 Z individually without a problem.
M28 however throws: ''Error: Failed to enable endstops''bed.g
G28 ; home G30 P0 X0 Y0 Z-99999 ; probe near a leadscrew front left G30 P1 X369 Y0 Z-99999 ; probe near a leadscrew front right G30 P2 X177 Y329 Z-99999 S3 ; probe near a leadscrew rear mid. and calibrate 3 motorsAlso I can run:
G30 P0 X0 Y0 Z-99999
G30 P1 X369 Y0 Z-99999
G30 P2 X177 Y329 Z-99999 S3
individually, and it does work as intended
G32 however also throws: ''Error: Failed to enable endstops''
I assume because my bed.g starts with G28config.g

@Nordle what's in your homeall.g?

I just remembered that when I first create files for this machine I selected by mistake coreXZ instead of coreXY in the configuration tool... I already changed that in config.g to corexy but didn't think of all the other files
could there be other corruptions?fixed my homeall.g to:

Nevermind this, was wrong again, but you got me in the right direction. Thanks for that^^

@Nordle said in Triple Z G28/G32 homing error:
G1 H1 Z-205 F360 ; move Z down stopping at the endstopG90 ; absolute positioningG92 Z0 ; set Z position to axis minimum (you may want to adjust this)
This part needs to be replaced by a G1 X Y move to position the probe, and then G30 to use the probe to home z.
