@svenyonson I just make my printer address my home page so whenever I open a web browser, there I am..
This does make me want to program an application in c#. Could add a few more things so it would be like dwc supports more.

I wasn't even trying at the time.. lol

@dc42 This would be a good platform to make a "guest" login. They could view all the details like the Job Status page but not be able to view other "administrative" sections. This is one feature I thought would be pretty cool for business purposes.

@droftarts Thanks very much!

Is there any repair service available? I assume we'll have to pay shipping, labor, cost of parts, but very much would love to have things repaired.
I've yet to pull the machine apart but getting ready to soon as I can't imagine life without it!

Thanks very much!

@infiniteloop Thanks for the input! Again it's been operating forever just fine, well passed useful dates most likely, so the probability of the board finally giving out under such heavy use over the years is way more likely than the 2 wires breaking at the same time, or 2 separate crimps at the same time, etc.

Any other suggestions from others?

Hoping dc responds with a magic diag code... Though I'm afraid the graph spells it out
Replacing the psu would be so much easier..

@infiniteloop Actually you did just reinforce it's the board. The bed heater didn't show that hiccup and it's directly connected via offload relay to the psu.
The 2nd heater wasn't on, but clearly has some sort of hiccup of the relay.

Again, you're trying to tell me that 2 different wires, have an issue all of a sudden at the same time, while all of the other 10-20 wires bundled with it don't have an issue, and I've taken great care to prevent long-term movement-breakage of these wires.
You realize the probability of that? It's not very realistic.
I'll have to tear it apart, but I'm afraid it's seen it's day

@jens55 I grouped all my wiring together, it's all tacked down, then leading to the carriage I used a multi-rubber band overhead crane setup, to guide the wiring taking great care to eliminate any sharp angles.
I've worked with pc's too long lol
But to have both fail around the same time, could be parts failing, but I haven't used extruder 1 for 80% of the time the machine has been up. So everything on that side should be pretty fresh on the MTBF timeline.
@dc42 is there a repair service if I pinpoint it to the board? It's a meanwell psu, which I may have taxed at the high end running a lot of prints at 120/245, but it's not out of the realm of possibility. My other psu is a generic 350 which wouldn't push that I don't think. Trying to recall what my upgraded bed wattage was, which indeed doesn't route through the board, I'll have to collect all the details.
Still hoping you might have a wonderful gcode tidbit that will give me some sort of 'power range from psu vs power range from individual outputs'..

@jens55 Two different sensors have faulty wiring at the same time?
I guess it's possible something could be pinched, I'll have to check it out.

@dc42 Is there any diagnostic you can think of that might aid in this scenario? Since it's gone down I have felt an emptiness inside I've not felt in years!

@jens55 Right, you would think the heater would just cut out or runaway.
Though like I said, it's 2 thermistors, both all of a sudden started doing this on both of my extruders. With both firmware all the way back in the 1 versions up to the new 3's.
It was operating perfect for the last idk, 5 years?
So I'm afraid it's the board or psu. Both out of warranty too
Both the psu and the board never go above 36-38c as I have fans dedicated to each...

@dc42
Here ya go

@dc42 Well now it successfully heated... I'll try a few more prints, iirc it was 'can't heat up to this temp'.. You can see the wobble in the graph

Otherwise it's not the firmware, I started having this issue on 1.21 or whatever it was. Was hoping it was a bug so new firmware looked promising...
Seems after going down that path it's still presenting randomly. This is after a pid tune as well. I've got an enclosure with all fans off, so it's not some random wind.
I'll follow up later, thanks so much DC42! Been awhile since I've been on the site I hope all is well!!

Just wondering, I'm on latest firmware now, hoping there's some sort of diagnostics for heater relay funcitonality or the psu power levels?
I was operating on extruder2, heater faults cropped up, changed thermistors from extruder1 to extruder2, then still got heater faults.
Wiring from board to psu is all mounted and screwed down.

Any input would be appreciated, I'm thinking it's either the board or the psu, I've already changed out the surge protector, I could try another outlet I guess in case it's a power dip on the outlet, but otherwise in thinking about the psu/board, really hoping there's some diags to pinpoint this
