What are you referring to? The initial problem?

The Answer

3DPMicro

@dougal1957. No solution yet. Narrowed it down though. It's either the sequence in which I am powering it up- 35v to the driver then power up Duet, Can't drive 4988 or 2130 from expansion or conn_lcd pins or something in firmware. Killed 4 drivers so far but not sure at exactly what point. Checked wiring many times. Have 3 more drivers coming to try again. Bizarre. Also plan to try a different capacitor on motor voltage side
Tried on both of the Duets I have with same result

@dc42
Would you mind looking at my config file? I have the 2130 configured and working correctly but the endtop is not right. If I put the T0 in the M584 command it triggers an E-stop (as expected) when the axis hits the endstop after homing X so the E2 end stop pin is right. Im confused about what "T" value is needed to execute the homex. Also drive 5 is showing the switch triggering. But need drive 0 to see this?
Also if I remove the M581, put X1 back into M574 and plug in to normal X stop pins it triggers "endstop hit" for drive 0 in machine properties but still doesnt work when attempting to home.

M584 maps drives, not endstop inputs. If you map drive X to driver 5, you still need to connect the X endstop to the X endstop input on the Duet.

3DPMicro

With it plugged in to the X stop under the Machine properties list drive 0 is toggling yes/no but it runs in to the end stop when homex button is pressed. This is how my config looks set up that way-

In case for a second you might have wondered
I M564'd the end stops so I could test the TMC2130.

Please post your homex.g file.

That part of your config.g file looks OK, so does homex.g. So if the "drive 0" endstop shows the correct status in DWC Machine Properties and/or in M119, you should be able to home X by itself. That is assuming that you don't have another M574 command somewhere else that is overriding the one you published.

@dc42
I cant see any conflicts. one thing I did notice was if I changed the speed in the first X move in homex.g to 180 from 1800 mm/m to give me time to press the switch by hand while the axes was moving towards home the motor sped up after pressing it so its seeing the switch
I was able to determine that the speed at which the motor sped up to is the programmed speed in the next G1, X move which is "; go back a few mm"

next I copied and pasted the homex example from dozuki doc. "Configuring RepRapFirmware for a Cartesian printer" and it slowed down after hitting the switch manually on its way to home which is how it is written.
G91 ; relative mode
G1 Z4 S2 F200 ; raise head to avoid dragging nozzle over the bed
G1 X-240 F3000 S1 ; move up to 240mm in the -X direction, stopping if the homing switch is triggered
G1 X4 F600 ; move slowly 4mm in the +X direction
G1 X-10 S1 ; move slowly 10mm in the -X direction, stopping at the homing switch
G1 Z-4 S2 F200 ; lower the head again
G90 ; back to absolute mode

seems the S1 is not producing the desired effect. Before this test with homex.g I have not changed any other FW files except for config.g. Sorry to be a PITA
