That’s awesome! Thank you guys very much. I’ll implement that and see how it works but may take me a while, never used object model before. I’ll let you know how it goes.
Again, thank you very much for your help!

@jay_s_uk
Right, that makes perfect sense (says the guy who hasn’t got a clue)
Once again, thank you very much!
The dual motor axis end stops configuration has always worried me because of the potential for disaster, (ask me how I know ) so this issue caught me off guard. I’ll implement it, test it and let you know how it goes. Cheers!

RE: Dual motor axis end stop woes
@tierod
it works! so awesome!
had to make a few changes, after trying this and that this is what i ended up with. dont know if it can be improved on but a couple things to note: will not work if you have the previous homing file stopping with the endstops triggered and it gives the warning :not sufficient axis homed" even when it works, not sure why? i would prefer have the original message you wrote. no idea how to fix that. could you give me your thoughts on the file? by the way, line 2 to 7 is indented, not sure why it comes up not; homeall.g

RE: Dual motor axis end stop woes
@tierod
hi all, just an update on this script
after changing the if statements to false, with the warning at the end it still gave me the red warning endstops not homed. so i moved it back behind the first if statement and it then gave me the correct blue error message.
it works perfectly this way so unless this is a bad move i’m going to leave it this way.
to reiterate, do NOT have your homing stop on the endstops as it will refuse to move, even 5mm off the endstops and all good.
again, thank you guys for this script!

RE: Auto squaring workbee Y-axis on Duet3D 2 v3.3.0
@facardi
as a side note, using a end stop for each motor, i ran into an issue while homing. i had a faulty endstop one time (shorted) and because i use nema 32 steppers the one side drove so hard i bent my y axis. the guys here helped me by writing a script that checks for shorts before it homes. it triggers a error message and stops homing routine. it works great! i don’t know how to give a link but just look for “dual axis woes” -

RE: RapidChange Automatic Tool Changer on the Duet
@meeloo
that’s great meeloo, i for one appreciate very much your willingness to share, especially the post processor. looks like you have it dialed in.
i have atc on the wishlist but would like to build it myself. so much to do, so little time -
RE: Dual motor axis end stop woes
@o_lampe
Thanks for that.
Edited the last post, is correct and works giving the proper warning now, just had to move the warning behind the first if statement. Sorry about the weird indentation! Oh and I also looked at the object model for the first time ️. What a great tool! I double checked the operation and it works with both left and right micro switches. I am so, so happy with this feature and I really think that all the people that help on this forum are number one in my books!! I believe this code should be made known somewhere easy to find, I can’t be the only one that has run into this issue. Again, thank you guys for your help!! Problem solved!

RE: Dual motor axis end stop woes
@tierod
hi again, i havent been able to get to my cnc yet but does the homeall have to look something like this?; homeall.g
; called to home all axes
G91 ; relative positioningif sensors.endstops[0].triggered = true ;if were hard against endstop or wiring faulty
or sensors.endstops[1].triggered = true ;as above
m564 h0 s0
g1 x-2 f1200
m564 h1 s1
m400
if sensors.endstops[0].triggered = true
abort "x endstop appears to be faulty. still in triggered state"
or sensors.endstops[1].triggered = true abort "u endstop appears to be faulty. still in triggered state"G1 H2 Z5 F6000 ; lift Z relative to current position
G1 H1 X-700 Y-400 F12000 ; move quickly to X and Y axis endstops and stop there (first pass)
G1 H2 X5 Y5 F6000 ; go back a few mm
G1 H1 X-235 Y-215 F360 ; move slowly to X and Y axis endstops once more (second pass)
G1 H1 Z155 F360 ; move Z up stopping at the endstop
G90 ; absolute positioning
g92 x0 y0
g1 x5 y5
g92 x0 y0
im clueless when it comes to anything about meta commands etc. i can sort of get around simple gcode
