When hotend heaters get enabled the duet restarts itself. All motion steppers works fine, runs fine. Bed is on a SSR with its own power source. This printer has been running untouched for over a year. (Very meticulously wired with proper sleeving, shrink, and crimp terminals where appropriate.)

Might be worth noting it is running a Duex5 Expansion, which has also been running in combination unchanged over the last year.

I didn't have much time and just assumed it was the power supply (MeanWell 24v) and replaced it with another meanwell (same spec) Not it.

As stated it has run untouched for over a year, now this out of the blue.

All connections are unchanged, look okay on visual inspection.

EDIT: SOLVED

• Issue with something hotend related..... Swapped hotend assemblies and its fine.

Shorted something on the connSD pins I believe. Board only works when connected via USB. Wifi doesn't turn on until it is connected. Connected to USB the board works fine, prints fine, everything is normal. I found this fried looking component but I'm not sure what it is, does anyone know or have a part number so I can replace? I have an SMD full-size soldering station and am proficient at soldering, just not good at component identification.

For sake of mentioning, I am running a DUEX expansion as well, not sure if that is relevant.

Thank you in advance. Yes I'm an idiot.

@andy-cohen That's odd, even with my probe issues I'm having FANTASTIC results with triple Z mesh compensation. I did design my Z positions so they intersect exactly at the corners of the bed though, not sure how much of a difference that makes.

@phaedrux How can I post a video? I uploaded it to youtube but when I try to post the link the it won't allow me as it "detects spam". The video is 30 seconds long and is too large to upload directly via the post tools. I will try to trim it.

EDIT: This current config works well enough that it allows it to complete compensation, but still has some false triggers.

I just did triple Z leadscrews/motors. I love it. Mesh bed compensation is magic. Love not really worrying about bed level. Designed it so the leadscrews intersect directly through the corners of the bed in the rear, then the front leadscrew is directly in the middle. Make sure you run a high quality gates belt if doing a triple Z, there is a lot of strain moving a heavy bed depending on your build volume. Make sure belt tension stays as consistent as possible.

I had the dive height from 5, 7, 10, and now 15mm. The hotend is not currently mounted 100%, I have to wire up the re-designed carriage I made. Here is the probe in action.
(wont let me post youtube link)
I have it working enough with the following config that it allows me to perform the mesh bed compensation but still has some false probes.

BL touch self triggering. When performing probing that involves moving sometimes it will trigger immediately once it moves to the next point.

Can not get it to stop. I have played with delay, travel speed, probing speed, trigger value, can't get it to stop self triggering when performing g32 or g29. I can run g30 s-1 and individual trigger points ALL DAY, but when i perform any kind of dynamic multi point probing it will self trigger, sometimes it won't. Any help?

Hypercube running triple Z. G30 s-1 reports dead nuts values when test-restesting during calibration.

Here is my curren't config. Running duet + duex

Have played with P value at 25, R value from .25 to 1, Probe speed from 100-400, Travel from 4000,5000, 10000, 12000. Cut and re-crimped/pinned connectors, tests good on the DMM, nothing unusual.

• As far as the large trigger value, I have played with the probe spacing, it was doing this same thing when the probe had 1mm spacing...

• It does not self trigger on every point

• Belts are tight, machine is aligned, running linear rails.
