Homing troble

gorf26

Here is my config.g and homedelta.g when i try to home all motors move but only about 10mm or so
The endstops seem right m119 shows low stop and when triggered show high stop for got the exact wording

If i enter gcode to move x50 and them x-50 also do both in the y direction they moved fine

just seems to be going to home its moving in the right direction when i home only in shot spurts

so i figure i have something configured wrong

Just setup the duet and fist attempt at homing I assume with delta it should be triggered at high end stops

Thanks gary

Your M574 command is wrong. See https://duet3d.dozuki.com/Wiki/ConfiguringRepRapFirmwareDeltaPrinter and https://duet3d.dozuki.com/Wiki/Connecting_endstop_switches#Section_Test_endstop_switches.

I tried setting M574 to x0 y0 z0 also x1 y1 z1 same results homes only 10mm when i make the changes they show up with m119
as the reverse to what was m119 showed before the change
the positon display on the duetweb shows x0.0 y0.0 z285.00 if i home all or g28 it shows x0.0 y0.0 z270.00

could the motors be reversed even thought they are moving toward the top end stops just thinking and the output went from 285 to 270 if homing on delta shouldn't the values be getting higher not lower?

got it working had to set m574 x2 y2 z 2 s0
then reverse the motor direction it homed fine hit endstops backed up and went up again and stoped
so i think i got over this problem on to the next one..

Thanks gary
