Prints crashing on raspberry pi.

dot_bob

I keep having prints crash when using the raspberry pi. I have reimaged the card, tried different cards, tried different power supplies, and tried two different raspberry pi's. It seems to happen at randomly they all have been at different points during the print. I have captured a log of the lastest print to crash: https://drive.google.com/file/d/0B1DusAxeMw1TNFlKS2NsMEtDeVk/view?usp=sharing<div> </div><div>-Rob</div>

It is serial communication that breaks. Port stays connected but does not transfer any data. This is often a problem with bad power stability on 5V from the board. You could try an active powered usb hub, a more stable main power for printer or a better usb cable if it is interference on usb cable.

If you have repetier-firmware you can try a data transfer only test. Send

M111 S24

and it will only run communication, no execution. Then printing is fast as it only sends data and you will most probably see it succeed as motors and heaters are all without power and do not cause voltage to change during print.

As far as I can tell it must be a bug in the RPI kernel. I have tried many iterations from hub to no hub and directly attached. I have tried two RP3's with different power adapters and pi and printers on completely different circuits. I have tried using the prebuilt image to installing everything on raspbian and I still get crashing. I have no issue if I attach the printers to a hub and use a 5 meter usb cable to my desktop running Repetier Server.

When it does fail I see this or something similar in the kernel logs retrieved with dmesg:

B0: ftdi_set_termios urb failed to set baudrate

[155675.158775] ftdi_sio ttyUSB0: urb failed to clear flow control

[155717.118943] cdc_acm 1-1.5:1.0: failed to set dtr/rts

If I remove and reinsert the usb devices in the pi they don't re-enumerate it requires a reboot to get the server to enumerate the printers again.

For now I can use the PI act as a remote terminal for the server on my desktop.

You also need to unpower the printer if you unplug usb to get a new port. That is why I think that it is the usb converter on arduino board that crashes. Seems like that chip is ot as stable as the main AVR.

With hub it is important to use a ctive one (with power) also with good Pi power I can use it without hub as well. Problem is that some usb cables that power pi are too thin dropping voltage or 5V units do not send full 5V. So if you can measure voltage on pi without anything else connected. Pi is also very sensitive on voltage. If you use original pi image you would often see the rainbow on hdmi output to indicate low voltage (our image has this disabled).

Here is an update.. I have been able to work around the buggy USB stack on the PI. It was actually my cameras that were crashing the USB stack on the pi not the printers. Anyways to work around the issue I added the following to the command line of the kernel:

dwc_otg.otg_cap=2 dwc_otg.fiq_enable=1 dwc_otg.fiq_fsm_enable=1 dwc_otg.fiq_fsm_mask=0x3 dwc_otg.lpm_enable=0

I don't know which specific option fixed my previous problem.

Now I have a new issue. Repetier Server crashed during a print and won't restart.

Here is a capture of the logs:
