duet 3d HC : Can Bus failed
-
I uses a duet 6hc (sbc mode raspi4) + 5x 1XD + tool distribution board + 4x toolboard for a change tool 4 tool with external stepper in X, 2xY, 2xZ
this morning by plugging in the machine to test the canbus connection no longer works on all external boards
yesterday it works perfectly (programming switch for toolchanger dock)
what will be the procedure to determine the failure pleasem122 === Diagnostics === RepRapFirmware for Duet 3 MB6HC version 3.3 (2021-06-15 21:45:47) running on Duet 3 MB6HC v1.01 or later (SBC mode) Board ID: 08DJM-956BA-NA3TJ-6JTDA-3SD6P-9A96T Used output buffers: 2 of 40 (15 max) === RTOS === Static ram: 150904 Dynamic ram: 60600 of which 0 recycled Never used RAM 142688, free system stack 202 words Tasks: SBC(ready,42.2%,314) HEAT(delaying,0.0%,405) Move(notifyWait,0.0%,352) CanReceiv(notifyWait,0.0%,908) CanSender(notifyWait,0.0%,374) CanClock(delaying,0.0%,339) TMC(notifyWait,6.4%,93) MAIN(running,31.0%,922) IDLE(ready,20.3%,29), total 100.0% Owned mutexes: HTTP(MAIN) === Platform === Last reset 00:01:10 ago, cause: power up Last software reset at 2021-10-19 12:26, reason: User, GCodes spinning, available RAM 142264, slot 0 Software reset code 0x0003 HFSR 0x00000000 CFSR 0x00000000 ICSR 0x00400000 BFAR 0x00000000 SP 0x00000000 Task SBC Freestk 0 n/a Error status: 0x00 Step timer max interval 14997 MCU temperature: min 32.3, current 36.6, max 36.6 Supply voltage: min 24.0, current 24.0, max 24.0, under voltage events: 0, over voltage events: 0, power good: yes 12V rail voltage: min 12.0, current 12.1, max 12.1, under voltage events: 0 Heap OK, handles allocated/used 0/0, heap memory allocated/used/recyclable 0/0/0, gc cycles 0 Driver 0: position 0, standstill, reads 4622, writes 11 timeouts 0, SG min/max 0/0 Driver 1: position 0, standstill, reads 4619, writes 14 timeouts 0, SG min/max 0/0 Driver 2: position 0, standstill, reads 4622, writes 11 timeouts 0, SG min/max 0/0 Driver 3: position 0, standstill, reads 4622, writes 11 timeouts 0, SG min/max 0/0 Driver 4: position 0, standstill, reads 4622, writes 11 timeouts 0, SG min/max 0/0 Driver 5: position 0, standstill, reads 4622, writes 11 timeouts 0, SG min/max 0/0 Date/time: 2021-10-19 13:46:04 Slowest loop: 10808.64ms; fastest: 0.00ms === Storage === Free file entries: 10 SD card 0 not detected, interface speed: 37.5MBytes/sec SD card longest read time 0.0ms, write time 0.0ms, max retries 0 === Move === DMs created 125, maxWait 0ms, bed compensation in use: none, comp offset 0.000 === MainDDARing === Scheduled moves 0, completed moves 0, hiccups 0, stepErrors 0, LaErrors 0, Underruns [0, 0, 0], CDDA state -1 === AuxDDARing === Scheduled moves 0, completed moves 0, hiccups 0, stepErrors 0, LaErrors 0, Underruns [0, 0, 0], CDDA state -1 === Heat === Bed heaters = -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1, chamberHeaters = -1 -1 -1 -1 === GCodes === Segments left: 0 Movement lock held by null HTTP* is doing "M122" in state(s) 0 Telnet is idle in state(s) 0 File is idle in state(s) 0 USB is idle in state(s) 0 Aux is idle in state(s) 0 Trigger* is doing "M950 J4 C"23.io0.in"" in state(s) 0 0, running macro Queue is idle in state(s) 0 LCD is idle in state(s) 0 SBC is idle in state(s) 0 Daemon is idle in state(s) 0 Aux2 is idle in state(s) 0 Autopause is idle in state(s) 0 Code queue is empty. === CAN === Messages queued 396, received 6, lost 0, longest wait 0ms for reply type 0, peak Tx sync delay 0, free buffers 49 (min 48), ts 352/0/0 Tx timeouts 0,0,351,37,5,0 last cancelled message type 30 dest 127 === SBC interface === State: 0, failed transfers: 1, checksum errors: 0 Last transfer: 15ms ago RX/TX seq numbers: 1668/1669 SPI underruns 0, overruns 0 Disconnects: 0, timeouts: 0, IAP RAM available 0x2c83c Buffer RX/TX: 2068/2660-0 === Duet Control Server === Duet Control Server v3.3.0 Trigger: Buffered code: M950 J4 C"23.io0.in" ;Gpin4 = Tool 3 Dock switch (on Toolboard 23);Gpin 4= T3 dock switch on 6hc Buffered code: M308 S0 P"temp0" Y"thermistor" T100000 B4138 ; configure sensor 0 as thermistor on pin temp0 Buffered code: M950 H0 C"out0" T0 ; create bed heater output on out0 and map it to sensor 0 Buffered code: M307 H0 B1 S1.00 ; enable bang-bang mode for the bed heater and set PWM limit Buffered code: M140 H0 ; map heated bed to heater 0 Buffered code: M143 H0 S120 ; set temperature limit for heater 0 to 120C Buffered code: M308 S1 P"20.temp0" Y"thermistor" T100000 B4138 ; configure sensor 1 as thermocouple via CS pin spi.cs1 Buffered code: M950 H1 C"20.out0" T1 ; create nozzle heater output on out1 and map it to sensor 1 Buffered code: M307 H1 B0 S1.00 ; disable bang-bang mode for heater and set PWM limit Buffered code: M143 H1 S300 ; set temperature limit for heater 1 to 280C Buffered code: M308 S2 P"21.temp0" Y"thermistor" T100000 B4138 ; configure sensor 2 as thermistor on pin 121.temp0 Buffered code: M950 H2 C"21.out0" T2 ; create nozzle heater output on 121.out0 and map it to sensor 2 ==> 676 bytes Executing macro config.g, started by system > Next stack level Pending code: M905 P"2021-10-19" S"13:48:16" Code buffer space: 2012 Configured SPI speed: 8000000Hz Full transfers per second: 8.44, max wait times: 18.7ms/0.0ms Codes per second: 0.27 Maximum length of RX/TX data transfers: 3599/608config.g

@bast said in duet 3d HC : Can Bus failed:
if you send M122 Bn to all the boards do you get an error for each one?
-
@bast what are the status LEDs on the main board and on the tool bards doing? Flashing in sync, or something else?

@dc42
all led flashes quickly
this config worked yesteday
i do some other test
when i plug just toolboard ,it s ok -
@bast try each of the 1XDs in turn to see if one of them is causing the problem.
-
@bast if the status LED on the 6HC is flashing at 1Hz, and the tool boards LEDs are flashing continuously and rapidly, then it indicates that CAN communication isn't working.
The most likely reason is a bad CAN cable between the Duet 3 and the tool distribution board, or between the tool distribution board and the first tool board.
Another possibility is that something is shorting the CAN bus out. You could try connecting just one tool board to the CAN bus at a time, to see if a tool board is shorting the bus. Remember to fit the jumpers on the tool distribution board to bypass any missing tool boards.
-
I tested all the boards independently
I have toolboard 0 (adress20) which creates a conflict for me in the general can bus
I am reconfiguring a toolboard to replace it
thank you
