@droftarts

Edit: After about 36 hours of uptime, I got the VSSA fault error too..

~~I have yet to experience issues on my idling machine. I'll probably try a print tonight and see how it goes.~~

When I initially installed the upgrade, my extruder thermistor (which is on toolboard TEMP0) was reporting something absurd like 2000C, but turning my 24v PSU off and then on again fixed that. ~~It's been sitting idle with no errors for the last 22 hours.~~

Setup: 120v wall power, 24V PSU, Raspberry Pi 3B+ with the Canakit PSU, Duet Web Control 3.3.0-b2, 5x motors, live thermistors for bed/hotend. Bed is a 12v bed connected via a MOSFET board, and it's connected to one of the GPIOs rather than the big high-current bed connector. M115 as follows from up-thread:

@dc42 Thank you! I loaded your 7APR firmware at 10:33 AM local time today and left the board sitting idle while I worked. It's now 18:50 with zero VIN under-voltage events, whereas I had at least one during this time-frame each of the last two days (with the machine sitting idle). I'm going to let the machine sit for another 24 hours before I try printing, but, signs are positive!

undefined

@droftarts Overnight, I had two more events:

I've tried two different PSUs and replaced 100% of the 24v wiring (before finding this thread), so I'm fairly certain it's not a power supply or wiring issue. Only remaining thing I could swap out is the 120V from the power entry module to the PSU, but this really feels like the same issue.

Good news is, I've got a build that seems to reliably generate failures every 12 hours, if you need more beta testers for firmware!

Due to the way my space is laid out, I'd need a wifi bridge (or to re-configure my SBC as a wifi bridge, I suppose) to use the Mini5 Ethernet without the SBC, so I'm down to test firmware for RRF.

undefined

Ok, I caught a VIN error while idle! See below: The error at 1:42 AM was the print failing. The error at 4:43 PM was the machine sitting idle.

undefined

@dc42

Also 0.0v. It's possible I mis-read my logs, but I am pretty sure of what I saw. Also of note: for at least some of that time, my heater was on because I am an idiot (but thankfully I didn't burn my house down). Of course I closed the RRF tab in Firefox this morning because my laptop was dragging -- is there any way to retrieve historical console data from SBC, so I could potentially see exactly when those messages happened and if the heater was on at the time?

[edit]On further thought, I'd say it's more likely that I misread my log, than that this is a new problem you haven't seen before. I'm going to leave my machine on and idle again with a console window up and see if I can capture this again.[/edit]

[edit]I can, in fact, Google, so I've enabled logging with M929 S1 P"vin-debug.log" and we'll see what we get. Is there any harm in adding this to my config.g considering I'm running on a 32gb SD card and there's no way I'm anywhere close to filling that? Would be nice if we could do auto log rollover (ie: save to a new filename after the file reaches a certain size) but c'est la vie! [/edit]

I left my printer sit powered on this week, and see 3 VIN undervolt events while idle. It also died again 3 hours into a 5 hour print last night. I'm happy to do whatever troubleshooting would help folks gather more info to get the root cause nailed down.
