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?

@bearer is there a certain reason that that would occur? also how does it destroy the drivers?

I checked using a multimeter that the pins on the motor were ABAB and wired to the board as AABB. But I'm getting no response whatsoever from the motor. I have tested at both 0.8 and 1.5 amps and also I am running just a single motor to test with no load. The motor doesn't even activate and can be easily turned by hand.
When the motor was vibrating and also not keeping its position while idle, it was wired ABAB on the board.

I picked up the new steppers and wired them up to the board. When I try to run them they just seem to be vibrating whether under load or not. When I use the provided jst connectors and run the motor there is nothing at all but when I use the setup for the previous motors they just vibrate. I'm pretty sure this is a wring issue but I'm not exactly sure what it is. I have them set to 1.5 amps witch is their rated current and they are wired in parallel to a single set of pins.

@Phaedrux since they are driving leadscrews that are holding a gantry that is about 3 pounds they need to be relatively strong but don't need to be extremely fast. I will pick up some new motors from stepperonline. Thanks for all your help guys.

Do you think these motors would be good?

I'm using 4 of them on the y and 1 on the x and they are providing plenty of power and seem to be accurate. It was only 30$ for 10 so its not a big deal to get new motors. And here is the latest version of the config for those who were concerned with errors.

I did not realize that those motors were not ok with 3d printers, I'm using them for driving every other axis on this machine and they all 5 seem to be working well. Do you recommend I just get new motors for that axis or is there anything else I can try?

Btw thank you guys for all the tips and ideas, I'm only 15 and this is my first fully custom printer build.

I tried wiring them in parallel and now neither motor activates whatsoever, but I will work on that.
As for the motor specs I will post them below. The entire gantry the 2 motors are lifting is between 2.5 and 3 pounds.

Tested with multimeter and redid wiring, the motors are able to drive both ways but function is still intermittent.

error message says 12/27/2020, 1:57:12 PM G28 X
Warning: motor phase A may be disconnected reported by driver(s) 2
Warning: motor phase B may be disconnected reported by driver(s) 2

Additionally I have problems with some endstops as well but I'm trying to figure those out myself but that's why the homing for x isn't happening.
