My printer stops ramdomly printing. It happen after one hours or two, every minutes or so, then start again, then after a while stops again, etc…
I do not use SD card, I only print through USB connection to a Raspberry or a PC.
After checking the logs files from Repetier, I see at each pause time, an error Warning Communication error on the USB port.
So, as suggested in the FAQ, I did try almost every item (ferrite, replace USB cable, wires connected, etc, etc…), but none of them work, and still print hang ramdomly.
One thing though: If I do stop heating bed, then no more problems…
If you have any idea how to solve this, I would appreciate, thanks
Can you try putting ferrite on endstops, thermistor inputs, motor cables and heater cables ?
Also, are you sure your power supply is reliable ?
Is your printer larger than usual ?
Thanks for your answer.
This printer is normal size, Prusa like (220x280mm). Power supply is brand new, coming from Amazon (Lixada AC 110V/220V à DC 12V 30A 350W )
It’s a 350W, it should be enough even if a have a dual extruduer configuration. However I’ll check again tonight.
I may try ferrites on switches and motors and heater. I took care about cabling, tried various configuration already.
Is 250000 the “perfect” baud rate for those boards ?
So I checked power consumption , it never exceed 20A, so ît should be ok.
Then I connected an oscilloscope on usb signal between the board and raspberry, the signal is not clean, even when printer is not working.
