sooo. i can get either 3.3v at the enable pin on power up or 0v depending on whether I send M569 P10 R0 or R1. On 4988 it should be 3.3v on power up then go low when commanded to move. It does not. Driver 0 and 2 stalled below

I can't remember whether firmware 1.19 supports drivers connected to CONN_LCD. You may need to use a later firmware version.

I dont blame ya.

@dc42
at this point I'm kinda confused. Ive read so much (valuable learning) and tried many different things. I think I'm close.
to recap- external driver through conn_lcd. Motor is not operating correctly.-2.0RC1 FW, 4988 driver (substitute for 2130 until sorted), 36v to driver, 24v to duet
-when attempting to home X axis motor rotates abruptly for a split second then stops
-driver gets real hot, real quick when enabled. 25-60c in a few seconds (thermocouple on driver chip)
-enable and direction signals are being transmitted correctly by duet
-configured to full step at driver
-3.25v @ pin 1, channel 10
-reducing accel or jerk seemed to effect behavior
-all changes in config.g have been entered manually. I sent M584, M569, etc but it did not write to config.g (I still dont understand something here)

If the driver gets really hot but the motor moves correctly for a few seconds, it's probably overheating because you have the motor current turned up too high.

What are you referring to? The initial problem?

The Answer
-
@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.; Configuration file for Duet Ethernet (firmware version 1.20 or newer)

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.

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-

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.

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.

G1 Z-4 S2 F200 ; lower the head again
G90 ; back to absolute modeseems 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
