homing dual z with independant motors

duet 2wifi 1.03 ,3.3 fw
cartesian printer
dual z motors connected to z +e1
dual z endstops connected to z +e1
probe connected to probe
can home x, can home y.
z tries to home, it moves to the upper switches and triggers the switches as indicated by the leds on the board but the motors keep trying to go and it just sits there and bounces on the stops, the e1 light flashes.

Is this being reported from when you send M98 P"config.g"?

@monkey68 said in homing dual z with independant motors:

@monkey68 the heater 0 is room temperature as in its not hot

If you're referring to the heater 0 temp warning it's just telling you what the predicted max temp could be in a runaway situation.

You've got E values listed twice in some of your commands. Why?
Do you have multiple extruders? If so the correct format is E###:### just like you had before for the Z axis. That format is only correct for extruders.

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?

Monkey68 · 14 Sept 2021, 04:17

@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

@monkey68 said in homing dual z with independant motors:

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.
