My end stops are not responding on the Duex5

georgepaul

I have built a printer with IDEX using a Duet Wifi and a Duex5. the X,Y and Z axis homes perfectly but then the homing switch that is connected to the Duex is not responding. i have connected the pins perfectly and the LED is glowing on the Duex and the limitswitch.
When i send a m119 code, the printer responds saying "Endstops - X: at min stop, Y: at min stop, Z: at min stop, U: not stopped" though the LED is lit.

am i missing some Mcode that configures the endstops???

I just tried connecting U axis to the duet and the extruder to duex and they work... Now really curious what I am doing wrong... am I missing a jumper(i have just one jumper on the endstop voltage connected on the duex)??

or is it still the firmware???

@georgepaul It might be best if you post your config.g file so that we can see. In particular do you have your M574 command after the M584 that creates the U axis?

this is the actual m584...the other one was a test i tried yesterday

M584 X0 Y1 Z2 U8 V9 E3:4:5:6:7 ; create the U axis and assign stepper driver 3 to it

dc42

You have 5 axes XYZUV and they will use the endstop inputs labeled X Y Z E0 E1 respectively. Remapping motors to outputs on the DueX does not remap endstop inputs.

georgepaul

@dc42
Oh thank you David.. no wonder it was working when i shifted them to the duet...
so is there any way to remap the endstops just to make things easier???

T3P3Tony

@georgepaul remapping endstops is part of the feature set of RRF3 but that is still experimental so I would not switch yet unless you have to have the functionality

georgepaul

@T3P3Tony looking forward to that
