M574 E12 S1 P"!e1stop"
Can you remove that line from config.g and send M98 P"config.g" again and see if it still spits out the endstop configuration?
-
@phaedrux ok i will remove them, the motor connected to E1 did not move before just the z and reading throught all of the comments and checking out the how to's which i have come to figure out are out dated and dont apply to the 3 series firmware is really confusing and should be sorted out and then you guys wouldnt be so busy doing the supposed simple stuff that we that are less affluent in the firmware can not work out, it was much simpler when i first got my duet as i could read the guides and copy the needed txt and like magic it just worked, sadly thats not the case anymore. sorry for the rant
-
The instructions are here for both RRF2 and RRF3.
https://duet3d.dozuki.com/Wiki/Bed_levelling_using_multiple_independent_Z_motors
What guides are you looking at that are out of date?

M574 Z2 S1 P"!zstop+!e1stop"
Ok, so now you can uncomment that line, which should be correct.
Now you can test the homing again, but this time click the switches by hand before it reaches them so that you have time to hit the estop if it doesn't stop movement.
You can also check the status of the endstops by sending M119. Check it when the endstops are depressed and again when they are not and see if it reports the state you would expect.
-
@phaedrux M574 E12 S1 P"!e1stop"
following the instructions given in the guides, specifying the stop for the motor and its place on the axis -
What guides?
E12 isn't valid in any way.
-
@monkey68 do you want me to remove all the extra e stuff i put in when you told me to remove all the z stuff?
-
Yes, all the duplicate E stuff is probably going to mess up your extruder.
-
@phaedrux said in homing dual z with independant motors:
E12 isn't valid in any way.
so how am i supposed to show the E1 drive high position?
-
You don't have to. The E driver is assigned to the Z axis and will take all of the settings applied to Z.
M574 Z2 S1 P"!zstop+!e1stop"
That line tells the firmware that the Z endstop will be the combo of zstop and e1stop.
Home the z axis as a single axis and it will take care of the rest.
It's a lot simpler than you seem to think it is.
Again, which guides are you looking at? If it's a Duet wiki page that is leading you astray, let me know and I can try and make it clearer.
-
@phaedrux ok thankyou for explaing that. So the endstops report as stopped when pushed in m119 and not stopped when not pushed but it doesnt stop the gantry had to estop[ it again
-
Can you copy and paste the results of M119?
Can you also post your current config.g and homeall.g just so I'm looking at the current versions you're actually using?
