Random underextrusion Problem
-
@matt3o that would be no problem. i got a spare cable thats long enough
-
Is your bed PID tuned? Perhaps it's the cyclical heating and cooling expand contract on the bed causing the Z gap to change.
-
@Phaedrux it is PID Tuned to 100 degree C. The same temp I was printing. The bed is a 4mm aluminium plate with a 4mm borosilicate plate on top. I let the temperatures stabilize bevor printing perhaps 15 to 20 min. Then a g32 +g29
Taper is set to 0, so it should be applied to the hole print.I also print in a heated chamber with 70 C

I am running now the first test print on 3.3 beta + LC1
here is a m122 from main and Toolboard at the start of the print

Did it help with theunder extrusion?
-
@Phaedrux i cant tell at the moment. with the new firmware my heater is going crazy
after 2-3 Minutes into the Print the Temp sensor starting to jump from 250 to 18-25 °C and my toolfan starts and stops accordingly to the temperature... when under 50°C it stops , above it starts.
-
Sounds like a bad connection on the thermistor
-
that was my first idea too, but when no print is running the temp is stable
-
@Frederik said in Random underextrusion Problem:
but when no print is running the temp is stable
Yes, because when no print is running, the cables are stationary.
-
@Phaedrux definetly not the cables
i resetted the Toolboard with the 2 knobs and restarted the same file:
absolute stable, nothing touched on the cables
-
@Phaedrux but what i can tell about the under extrusion, it seems that the artefacts are gone
after this i will print the same Led_Bar.gcode from the last time,
where the Problem occured.But it seems that the Print Quality is restored
This is a Picture where the Problem is better visible. It was switching between under and over extrusion in always the same intervals
-
M122 at the end of the Print,
I have to print a bigger object to check if the Problem is gonem122 b121 Diagnostics for board 121: Duet TOOL1LC firmware version 3.3beta (2021-01-21 11:34:37) Bootloader ID: SAMC21 bootloader version 2.2 (2021-01-16b1) Never used RAM 3692, free system stack 0 words Move 90 HEAT 91 CanAsync 66 CanRecv 74 CanClock 66 TMC 56 MAIN 205 AIN 62 Last reset 00:35:43 ago, cause: software Last software reset time unknown, reason: OutOfMemory, available RAM 15632, slot 1 Software reset code 0x01c0 ICSR 0x00000000 SP 0x20003578 Task MAIN Freestk 747 ok Stack: 20000d10 00011ceb 20000d10 0001df61 00000000 00004008 20000d10 0001ded5 20000d0c 00004000 a5a5a5a5 a5a5a5a5 00000000 0001dd9d 00004000 00018b21 a5a5a5a5 00018b3d a5a5a5a5 00011b39 a5a5a5a5 a5a5a5a5 a5a5a5a5 a5a5a5a5 a5a5a5a5 a5a5a5a5 a5a5a5a5 Driver 0: position 450451, 859.0 steps/mm, standstill, SG min/max 0/0, read errors 0, write errors 0, ifcnt 14, reads 831, writes 0, timeouts 0, DMA errors 0, steps req 0 done 0 Moves scheduled 9915, completed 9915, in progress 0, hiccups 0, step errors 0, maxPrep 0, maxOverdue 0, maxInc 0, mcErrs 0, gcmErrs 0 Peak sync jitter 3, peak Rx sync delay 183, resyncs 0, no step interrupt scheduled VIN: 23.5V MCU temperature: min 48.7C, current 69.2C, max 74.0C Ticks since heat task active 57, ADC conversions started 2139229, completed 2139228, timed out 0 Last sensors broadcast 0x00000002 found 1 64 ticks ago, loop time 0 CAN messages queued 52, send timeouts 0, received 23, lost 0, free buffers 36, min 36, error reg 0 dup 0, oos 0, bm 0, wbm 0 === Filament sensors === Interrupt 4 to 8us, poll 28 to 181us Driver 0: pos 5.54, errs: frame 0 parity 0 ovrun 0 pol 0 ovdue 0

When you pid tuned the bed, did you put B0 in the result?
The new tuning hint leaves it off, so if you just copied that rather than using M500, it will default to bang bang.
Wouldn't have thought it'd affect that high up the print and you should see a cyclic temp variation, but worth checking. -
@OwenD Thanks for the tip. I checked it, in my config was the old version, but in config.override there was the new Version with B0 at the end.
But i have this Parameter normal in a additional Line

Yesterday i did some testprints with the extruder connected to the Toolboard, then to the Mainboard.
The first row of test was a disaster when connected to the Toolboard Driver.
Again Massive Underextrusion and other artefacts.
The Heatertemp jumped around and the LaserFIlamentSensor was constantly reporting to little movement (30:130,3mm)
i had to abort the print at around 50% , after restarting it from Pause around 8 Times.
The same Print connected to the Mainboard Driver 5: No Heater or Filament Sensor Errors! The Print Finished as expected.
Today i changed the Toolboard Firmware to the Version Previous Januar16, that is also in the 3.3Beta Folder.
I running the same Prints again to check if it is better.
since Updating to 3.3 i have no BLTouch Probing Errors the last 2 Days.
