Very true. Power supplies can and will fail at some point. I'll order a spare in the near future to have on hand.

Just wanted to give a little update.

Finally had some time to get into the printer and check the connections. They all felt tight but I loosened and retightened them. Then went through the upgrade process to 3.3 again.

Now it works! Not sure what it was exactly but in any case it's heating and not crashing for now.

Still want to make a new wire loom for the hotend and have some wire on
order. If there are any electrical issues hiding in there somewhere hopefully that will straighten them out.

Thank you all for you help!

@siam
I can't easily see the board where it is in the printer. I'm pretty sure it says 1.04 something.

@dc42
It has been probably about 2 years since I did anything with the wiring on this printer. Loose connections are possible. I used crimp on terminals and ferrules at a all points though. The main concern is that a lot of the wiring isn't motion rated. It's highly possible that some of the copper strands have begun breaking in the jacket.

@droftarts said in Bed heater crashing Duet WiFi at set point:

@adarack Can you post your RRF2 config.g? Maybe you're using bang-bang control. I'd suspect that using PID (or a high switching rate) is causing your PSU problems, though your M122 reports show 'HardFault invState' once and 'HardFault undefInstr' twice as the reason for the software reset. One for @dc42 to look at.

Ian

Those 2 faults were from different operations. I was attempting to PID tune the bed at one point. Then after getting a successful tune I tried to heat it. Not sure if that matters though.

@phaedrux
I ended up erasing the flash and using bossa to reflash it. It seems to have worked.

So I'm at a loss at this point. There are a couple of possibilities I can think of.

I had a bad flash. I didn't test anything when 3.0 was installed, just went straight to 3.3. So I followed the guide and did 2.05 -> 3.0 -> 3.3 and reworked the config.
Something is electrically wrong (a very real possibility) and 3.3 has an issue with it whereas 2.05 ignores it.

The wiring on this printer is quite old now and it defiantly could use some attention. Especially with all the ABS that has been pushed through it. Also, this board is getting a little old as well and it's on its second printer.

It is odd that it only seems to happen when the PID begins to do its work. It will heat fine till it gets close to the setpoint then crash with a hard fault. It only fails on the bed, hotend, and chamber heater work fine.

Thank you to everyone who chimed in. I think I will leave it on 2.05 for the immediate future and check all the wiring before attempting the upgrade again.

@o_lampe
Tried with all fans unplugged and it's the same. Thank you for the idea though

@siam
Gave that a shot. I can get the PID tune done at 90c. It seems if I set the heater to any value it will reset once it's near the setpoint. So I'm starting to think that something is buggy with the PID on my board.

Might have to erase the firmware and reflash. Might just go back to 2.05, with the old config, and see if it still works as it used to.

Decided to try a PID temp of 90c. So entered M303 H0 S90. It completed but with an error.

Warning: heater behaviour was not consistent during tuning
Auto tuning heater 0 completed after 3 idle and 25 tuning cycles in 2939 seconds. This heater needs the following M307 command:
 M307 H0 B0 R0.279 C670.9 D3.01 S1.00 V23.8
Send M500 to save this command in config-override.g

After a M500 I tried to set the heater to 90c and the board reset as soon as it reached the setpoint.

@siam said in Bed heater crashing Duet WiFi at set point:

@adarack does M98 P"configt.g" throw any errors? Which command did you use to PID tune the Bed? What kind of Bed Heater you are using (24V / 230V how much Watts) Is it directly connected to the duet or did you use a SSR?

Thank you for the reply!

M98 P"config.g" shows no errors.

M98 P"config.g"
HTTP is enabled on port 80
FTP is enabled on port 21
TELNET is enabled on port 23
Warning: Heater 2 appears to be over-powered. If left on at full power, its temperature is predicted to reach 365C

The bed is 24v directly connected to the Duet. Not sure of the wattage but I would guess it's the same bed Creality uses of the Ender 3 Pro which is 220W .

The power supply is a 350W Meanwell 24v.

EDIT.
The command I used for the PID tune was M303 H0 S100

I'm having a strange issue and hoping someone can help.

I recently updated my Duet 2 WiFi to RRF 3.3 from 2.05. When on RRF 2 everything was working fine mechanically and electrically.

Now however anytime I try to PID tune the bed the Duet crashes. Shortly after "Auto tune starting phase 3, heating system settling" shows in the console the board will reset.

Tried reflashing the firmware a couple of times both through the DWC and using YAT over USB. The result is the same.

Honestly at a loss of where to go from here and would appreciate any guidance you could give

Thank you.

M122 for the most recent crash while trying to PID tune the bed.
