Resetting the printer during a print in random places

Kevvv

Hi, I have a 3d printer with a duet 6hc control board. The printer is for pellets, so two heaters are installed, which are connected to the board via SSR 5A. The melting system is driven by a gearbox. The power supplies are MEAN WELL LRS-350-24. The height sensor is an IR probe. For how long have I been struggling with the problem of resetting the printer during a printout (reset occurs in random places).

My observations show:

accidental reset occurs when retraction is enabled,
I placed the entire control system outside the frame of the 3d printer so that the vibrations do not pass, but the reset still appears,
resetting occurs regardless of the model.

Have any of you had a similar problem and can help me?

@Kevvv Consider upgrading to the latest v3.4.5. Did you capture the M122 output after an unexpected reset? If yes, it indicates that there is an intermittent power connection on your setup. Check if the power cables are fitted tightly and if the blade fuses have proper contact on the board.

Kevvv

@chrishamm I had the same problem on previous versions of the software but I will try to update to the latest one.
I'm using Duet Web Control and after a reset it takes a while for it to reconnect, but the M122 boots up immediately after reconnecting.
Does this mean a loss of main power or maybe one of the motors? Is there any way to check?

chrishamm

@Kevvv That diagnostics output just tells me that the reason for the last reset was not caused by the firmware (Last reset 00:03:00 ago, cause: power up). So it may be your power wiring, blade fuses, or the PSU.

@Kevvv said in Resetting the printer during a print in random places:

My observations show:

accidental reset occurs when retraction is enabled,

I suspect that either retraction is overloading the power supply (which seems unlikely), or retraction is causing the extruder to generate static charge, which is discharging through the Duet. Try grounding the hot end metalwork and the extruder motor body.

Kevvv

@dc42 Thanks for your help, I grounded all the motors but from what I noticed especially grounding the Y axis helped.

dc42

@Kevvv that's interesting. We've suspected that belts might accumulate static charge, but we've no evidence that they do; whereas we have reasonable evidence that some hot ends accumulate static charge.
