Printer resetting mid print
-
Hi,
lately my printer is just resetting mid print. I'm driving a Duet Wifi with an E3D Chimera with the latest stable firmware. The reset is mostly happening after a while and never at the beginning. It's happening with Cura and Prusaslicer generated gcode files and with different STL's. I also tried a different SD card with no effect.Here's the M122 output directly after a reset:
M122 === Diagnostics === RepRapFirmware for Duet 2 WiFi/Ethernet version 2.04 running on Duet WiFi 1.02 or later Board ID: 08DGM-956GU-DJMSJ-6J9FJ-3SD6N-KTPZG Used output buffers: 3 of 24 (13 max) === RTOS === Static ram: 25680 Dynamic ram: 93080 of which 0 recycled Exception stack ram used: 268 Never used ram: 12044 Tasks: NETWORK(ready,764) HEAT(blocked,1232) MAIN(running,3768) IDLE(ready,200) Owned mutexes: === Platform === Last reset 00:00:23 ago, cause: power up Last software reset at 2019-12-10 00:27, reason: User, spinning module GCodes, available RAM 11924 bytes (slot 0) Software reset code 0x0003 HFSR 0x00000000 CFSR 0x00000000 ICSR 0x0441f000 BFAR 0xe000ed38 SP 0xffffffff Task 0x4e49414d Error status: 0 Free file entries: 10 SD card 0 detected, interface speed: 20.0MBytes/sec SD card longest block write time: 0.0ms, max retries 0 MCU temperature: min 38.6, current 39.8, max 40.1 Supply voltage: min 24.4, current 24.5, max 24.7, under voltage events: 0, over voltage events: 0, power good: yes Driver 0: standstill, SG min/max not available Driver 1: standstill, SG min/max not available Driver 2: standstill, SG min/max not available Driver 3: standstill, SG min/max not available Driver 4: standstill, SG min/max not available Date/time: 2019-12-10 01:47:47 Cache data hit count 73739878 Slowest loop: 2.08ms; fastest: 0.06ms I2C nak errors 0, send timeouts 0, receive timeouts 0, finishTimeouts 0, resets 0 === Move === Hiccups: 0, FreeDm: 160, MinFreeDm: 160, MaxWait: 0ms Bed compensation in use: none, comp offset 0.000 === DDARing === Scheduled moves: 0, completed moves: 0, StepErrors: 0, LaErrors: 0, Underruns: 0, 0 === Heat === Bed heaters = 0 -1 -1 -1, chamberHeaters = -1 -1 === GCodes === Segments left: 0 Stack records: 2 allocated, 0 in use Movement lock held by null http is idle in state(s) 0 telnet is idle in state(s) 0 file is idle in state(s) 0 serial is idle in state(s) 0 aux is idle in state(s) 0 daemon is idle in state(s) 0 queue is idle in state(s) 0 autopause is idle in state(s) 0 Code queue is empty. === Network === Slowest loop: 15.79ms; fastest: 0.00ms Responder states: HTTP(0) HTTP(0) HTTP(0) HTTP(0) FTP(0) Telnet(0) Telnet(0) HTTP sessions: 1 of 8 - WiFi - Network state is running WiFi module is connected to access point Failed messages: pending 0, notready 0, noresp 0 WiFi firmware version 1.23 WiFi MAC address 5c:cf:7f:76:64:03 WiFi Vcc 3.33, reset reason Turned on by main processor WiFi flash size 4194304, free heap 25464 WiFi IP address 192.168.175.48 WiFi signal strength -48dBm, reconnections 0, sleep mode modem Socket states: 0 0 0 0 0 0 0 0Let me know if you need any more information.

Can you include your config.g and a description of the printer hardware?

It origins from an Anet A8 but there are pretty much only the stepper motors and the z spindles left. It's running on 24V, powered by a Meanwell 320W power supply.
The E3D Chimera is set up with 24V 40W heating cartridges and 100k NTC thermistors and the heated bed is an Anycubic Ultrabase.
Let me know if I missed anything.

The only thing that occurs to me is that the MCU temps reported by the M122 and then seeing that the printer may be in an enclosure?
Have you gone through this process to calibrate the MCU temp sensor?

Is there any active cooling on the board?

There are actually two fans. You can barely see them on the picture. One going directly onto the board, and one exhaust fan above.
Usually the temperature in the enclosure doesn't exceed 30°C, even with the heated bed set to 100°C. As far as I can tell the MCU temperature is at around 40°C when printing. The last two prints failed at around 45 minutes.
I'll try to calibrate the MCU temperature sensor tomorrow and report back.Thanks for your help so far.

The reported last reset in the M122 is power up. Which I think would indicate a powerloss. Is the PSU also in the enclosure? Could it be failing?

Yeah, the PSU is mounted to the printer. It's a Meanwell RSP-320 with a fan so I'm not sure if that can fail.

@Phaedrux I just remembered I had some issues when I initially set up the Duet. It would restart if I set the PWM limit for the heaters too high. So my guess would be that something draws too much power and when the PSU gets a little warm it just cuts off. Do you think that'd be a possibility?

What is the wattage of the heated bed? Are you sure it's a 24V heater?
The greatest draw would be during the warm up phase. Once it's at temp it doesn't take as much power to keep it warm, especially since you have it in an enclosure.

@Phaedrux it should draw 140-145 watts. Here's the data sheet:
Heat Bed Power: 140-145W
Heat bed Specification:
(1)Material: Aluminum base
(2)Voltage: 12V/24V
(3)Max Temperature: 120 Degree Celsius
(4)Dimensions: 220mm x 220mm
(5)Thickness: heat bed 1.5mm
(6)Resistance around 0.9ohm for 12V
(7)Resistance around 3.6ohm for 24V
(8)100 Degree Celsius supported for both 12V and 24V
