[BUG] BTT SKR 1.4 Turbo, extruder stops mid print, TMC2208

Jeroentjj commented 4 years ago

I installed the BTT SKR 1.4 Turbo and have been able to print for a while. Recently the extruder would stop mid print. X, Y and Z would keep going and heating was kept on. After stopping print extruder wouldn't move with loading/unloading commands, above Cold Extrusion temperature. Rebooting made extruder move again. Changed Vref to 1.1V on all BTT TMC2208 V3.0 stepper drivers and test-printed again, problem remained. After running M122 with Pronterface I discovered UART communication errors on multiple axii. All communications on X, Y and Z are OK now, but I am unable to resolve E0. I also tried changing the pins of E0 to E1, but problem persists there too. I tried multiple stepper drivers, all pads soldered correctly but still ALL LOW on E0. Also tested with known working ones (from X, Y or Z).

I added the TMC stepper library below: TMCStepper=https://github.com/teemuatlut/TMCStepper/archive/master.zip

Also tried modified library: TMCStepper=https://github.com/sjasonsmith/TMCStepper/archive/stopListeningOnBegin.zip

Also tried adding SoftwareSerialM but to no avail: SoftwareSerialM=https://github.com/FYSETC/SoftwareSerialM

My Configurations

Printer: Ender 5 Board: BTT SKR 1.4 Turbo with 3.5 TFT firmware: Marlin-bugfix-2.0.x , downloaded yesterday Stepper drivers: BTT TMC2208 V3.0

Testing E connection... Error: All LOW

Steps to Reproduce

Build marlin bugfix 2.0.x with configuration.h and configuration_adv.h
Install BTT TMC2208 V3.0 on all axii
Run M122 with pronterface

Expected behavior: [What you expect to happen] report: Testing X connection... OK Testing Y connection... OK Testing Z connection... OK Testing E connection... OK

Motor motion on E0 when above cold extrusion prevention, completed print

Actual behavior: [What actually happens] Testing X connection... OK Testing Y connection... OK Testing Z connection... OK Testing E connection... Error: All LOW motor motion above cold extrusion prevention, but stops mid print.

Changed Vref to 1.1V

Changes was made on the Trimpot?

I discovered UART communication errors on multiple axii

Wich Axis?

have you tried to raise the current for e0?

Jeroentjj commented 4 years ago

Hi and thank you for your reply. Yes the change was made with the trimpot. I can't quite remember which axis had issues, I believe X, Z and E0. All all working correctly now except E0.

The video in the link below, starting from 0:55, mentions the vref should be between 0.8 and 1.1V for standard nema17 motors. It's getting hot - How to set the Vref on TMC2208 I remember the extruder vref was at 1.4V, and on this vref it shut down mid print. I have not tried raising the vref again. To what voltage would you recommend?

elmolinger commented 4 years ago

1.4Volt seems too high for me, but shouldn't have killed the driver already. 1.1V is ok (my bad I thought about tmc2209 @ answering)

Rebooting made extruder move again. Changed Vref to 1.1V on all BTT TMC2208 V3.0 stepper drivers and test-printed again, problem remained.

M122 shows Error: All LOW on E0 still after the reset? Or OK?

Non of your links are working so it's a bit difficult to find the sources ;-)

Checked if the UART cable set correctly? Tried to swap cable?

Jeroentjj commented 4 years ago

M122 keeps giving E0 ALL LOW also after rebooting and also after re-flashing firmware. I have one TMC2130 which I also tried, set up in SPI mode, which resulted in ALL HIGH. The SKR 1.4 Turbo should have internal circuitry to allow direct UART communication with the LPC1769 chip, so I have no UART cable. I did try plugging in a different stepper motor cable, the one from Z axis but had no effect. Could I route the UART signal from the stepper driver to a different pin on the board? Not sure if that might help but could be worth a try.

Jeroentjj commented 4 years ago

sorry for the broken links, I've updated my replies and fixed the links. I wasn't using the syntax right.

elmolinger commented 4 years ago

Sry, but routing pins from stepper driver is above my experience.

It looks like broken board. Can you replace it?

The board is almost brand new so I don't believe it's broken, however as I've seen so many people with the same or similar problems I feel it is due to how the board is designed. I don't have a replacement by hand, other than the original Melzi board but it is incredibly loud. I'm either considering to go to the original creality silent board I can buy from a local webshop or try out the mks Robin board.

I also have this problem, runs a little (Printing) And then it stops. I also uses skr 1.4 turbo and TMC2208 in uart mode.
