ToolBoard: 2 wires fan, heater fault and how to extrude ?
-
i dont know where it could come from.
i would play a bit with the H and L values.
what do you get when you set the same on both?
-
@Veti I have a difference too, but I played a bit with the H and L value and now it is okay, the hotend doesn't return fault.

@Pseud3mys said in ToolBoard: 2 wires fan, heater fault and how to extrude ?:
I check the 2 resistances values, both are at 4.34 Kohm (~11°C). but one thermistor return ~10°C degrees more than the real temperature (~21°C)..
And it is enough to raise a fault with the heater, so it is disturbing.M308 S1 P"121.temp0" Y"thermistor" T500000 B3600 C1.196220e-7 H-12 L0 M308 S2 P"122.temp0" Y"thermistor" T500000 B3600 C1.196220e-7 H-10 L-12
All the value are equal exept for H and L but they don't change anything significantly (I tried to put the same value).
So why one of the thermistor return a wrong value ?You don't need to set the H and L values in config.g because after you run the semi-automatic calibration procedure, the required H and L values are store in non-volatile memory.
You could try removing the H and L values and run the semi-automatic calibration again on the board that is showing the error. But if that doesn't work, use your manually-adjusted H value.

@dc42 I change the H value manually and now it work. Thank you for your help !

@dc42 I have same problem. After few hours of printing the extruder heater goes offline, temperature goes to 2000 °C (I'm using PT1000)
Updated to latest 3.2-beta4.1 and problem remains. It keeps printing so I guess it's still keeping 220 °C, but to CAN bus it reports offline status.

Any thoughts? Can I contribute with more debug infos to solve this?

@flajzi, it looks as though the heat task stack may still be too small. Please try the tool board firmware at https://www.dropbox.com/sh/jv86vnaqjs1j4qd/AAA00AGN-pHCX4ok4L81ukv-a?dl=0. Post a fresh M122 B1 report when either the problem occurs again or the print finishes.

@dc42 Hi again. Problem with 2000 °C is back.
It's keeping same temperature, but it reports nonsense.

@dc42 And hello again... Problem with 2000 °C persists also in RC1 release...
I don't know if that could be an issue, but I'm using PT1000 sensor instead of thermistor...Diagnostics for board 1: Duet TOOL1LC firmware version 3.2-RC1 (2020-12-19) Bootloader ID: not available Never used RAM 3960, free system stack 38 words HEAT 86 CanAsync 89 CanRecv 83 TMC 54 MAIN 219 AIN 64 Last reset 03:17:23 ago, cause: power up Last software reset at 2020-11-22 15:02, reason: HardFault, available RAM 4168, slot 0 Software reset code 0x0060 ICSR 0x00000003 SP 0x200011c8 Task Freestk 4294967295 ok Stack: 20001018 20001304 0000000f 00000001 20000928 000172cd 00018250 01000000 00077dfa 00077ef4 20001218 200032d0 00000020 00017a61 20004660 00000000 20001300 00008895 00077dfa 20004670 00077ef4 42651000 a5a5a5a5 a5a5a5a5 a5a5a5a5 a5a5a5a5 a5a5a5a5 Driver 0: position 7455393, 409.0 steps/mm, standstill, SG min/max 0/112, read errors 0, write errors 0, ifcnt 16, reads 23696, writes 16, timeouts 0, DMA errors 0 Moves scheduled 218054, completed 218054, in progress 0, hiccups 0 No step interrupt scheduled VIN: 24.2V MCU temperature: min 36.8C, current 51.7C, max 62.4C Ticks since heat task active 198, ADC conversions started 11796908, completed 11796907, timed out 0 Last sensors broadcast 0x00000002 found 1 202 ticks ago, loop time 0 CAN messages queued 142406, send timeouts 0, received 324917, lost 0, free buffers 36
My setup is this:
M308 S1 P"1.temp0" Y"pt1000" A"Nozzle"; configure sensor 1 as PT1000 on pin 1.temp0 M950 H1 C"1.out0" T1 ; create nozzle heater output on 1.out0 and map it to sensor 1 M143 H1 S285 ; set temperature limit for heater 1
-
Please post your complete config.g file.
Does the 2000C error occur immediately after starting the system, or is the displayed temperature normal at first and changes to 2000C and heater offline later? If it occurs immediately, try putting a G4 P500 command right at the start of config.g.
-
I have had the same issue. But I found out that screw in terminal block was broken, so i just soldered thermistor wire directly to PCB and problem dissapeared. So check wires and terminals.
-
@dc42 It always happens after few hours of printing. It never happens at the beginning of printing.
-
@Meltex @dc42 My issue is propably different. When it fails, toolboard is always keeping correct temperature at nozzle. It normally continues printing, toolboard is only reporting wrong temperature to Duet motherboard.
When I reset toolboard (unplug/plug power to whole printer), after startup it shows last correct temperature, few degrees below last defined temperature (hotend is cooled few degrees during restart).
So, PT1000 sensor is all time (even when toolboard reports fault to Duet board and 2000 °C) reporting correct temperature to the toolboard. -
