Sent the reboot command then followed with M98"config.g". I haven't finished setting up the tool and don't have thermistors or heaters connected currently.

I'm having trouble getting my duet wifi 2 to recognize that I have remapped the endstop for the X axis to the "e0stop" pin. Despite seeing the led next to the correct driver flash off when the endstop is pressed, when using the m119 command to check endstop status it reads triggered whether or not the endstop is pressed. I've tried messing around with it for a bit but still haven't found anything that works. Despite this minor issue the Y stop works perfectly as is.

Here is my config:

Any ideas would be great.

@deckingman Thanks for the suggestion, replaced the thermistor wire and now its working fine

Out of the blue my printer started failing due to heater faults (temp excursions). I looked for a reason and could find none. It heats up to temp and the thermistor works properly until it starts printing. After about 2 minutes it starts having excursions and not measuring properly.

• I just replaced the thermistor
• The wiring seems fine
• There is no part fan
• There is a silicone sock on the heater block
  Could there be some interference from the motors or something?
  I'm quite lost, any help would be appreciated.

@siam Thanks, thought I had to reference the extruder/tool it accompanied in that line. The problem is gone, thanks a lot.

My T0 slot is constantly in fault, reading "N/A" for the temp.
But my T1 slot is working fine. I am able to switch the 2 thermistors present on the board with the same result.
In duet web control I have 2 heaters mapped to 1 tool, each with their own thermistor:

Any ideas what could be causing this?

@bearer said in z motor not driving when connected to leadscrew:

TMC2660-PA driver

I have a soldering iron and hot air gun for soldering, since its a surface mount part that might be a bit tricky though. I was reading awhile back that you could connect additional drivers to the board so would I be able to use one of the A4988 drivers and connect it to the expansion headers?
If not is this the correct part to replace the driver?https://www.digikey.com/en/products/detail/trinamic-motion-control-gmbh/TMC2660-PA/4500212

Only weird thing is there is no visible damage to the driver itself or any of the surrounding components. Additionally now that I have the motor connected correctly I'm getting the error message that phases A and B may be disconnected.
Here is my config again, and for the test I was running on of the new motors with the x axis driver.

used the exact cable and motor but on a driver I knew worked and it spun fine. Does this mean my driver is dead? and if so how do i replace it?
Also I already have some extra A4988 divers so could I somehow use that instead/ to replace the other driver?

@bearer If it were a driver issue would there be any ways to know, like does it look like other blown out chips?
