My anet a8 based printer has been stopping roughly an hour or so into the print. I have been running from an SD card from viki 2 display. Reading some other post I used the USB with pronterface. When I got back home from my cook out the printer was stalled still at temp with the following message.


[ERROR] Can't read from printer (disconnected?) (SerialException): call to ClearCommError failed
[ERROR] Can't write to printer (disconnected?) (SerialException): WriteFile failed (WindowsError(22, 'The device does not recognize the command.'))

I have sleep mode turned off and was 10% into the print. Thoughts. Thanks Tim

What board do you have, and what does your config look like? Using latest firmware and config?

V1 5X config file attached the saved original config file is from 4/19. I don't think it is the latest but has been working fine for months.

I currently have it printing directly from the smoothieboards SD card using the viki 2 controller. I will see what happens.

Arthur,
I had filament jam at 49% which is the furthest I have gotten. Did you have a chance to look at my config file? Should I reflash my firmware before I start printing again?
Thank you for your time.

Remote SD Cards are pretty much well known for having crashes on a regular basis. Would you mind trying to print from the on-board SD card and see if it helps?

not only that but you MUST totally disconnect the external sdcard as the wires leading to it will also interfere with the internal sdcard. You can't run SPI wires like that, they pick up too much noise.

Arthur,
I attached is my pinout for the viki2. What would be your recommended changes to disconnect the external SD card and keep the rest of the functions operational. My thoughts are I comment out everything under external card and disconnect from pin 0.27 and 0.28. Its funny though I have been printing in this configuration for a couple of years now with no issue. Why now, anyway, I have cleaned things up with my printer and will give it another shot. Thanks for your help

ok as you are using the alternate sdcard connections no need to disconnect them. (Some people use the internal sdcard spi connections which would need to be disconnected)

I would just comment out the external sdcard in config and play from the internal sdcard. 

Noise is unpredictable, and any change in wiring or routing of power cables can change it.

If it still has issues playing from the internal sdcard then you need to look elsewhere for the problems.
