Another Layer Shifting Issue

Veti

what kind of print is it?
i had problems with some pla prints where the edges were curling up on overhangs.
When the nozzle went across it, i got layer shifts.

Turbo

containers for a resistor box. simple squares with a divider in the middle. No curling to be seen.

just out of curiosity, what motors do you have? your currents seem a little low

@jay_s_uk original motor part is in og post

Hi .... it also happened to me in a previous printer, I also changed the power supply only to discover that it was a false contact in the motor cables. I changed them directly even if measuring them several times with the tester (at that moment) they were always ok.
Now, I don't know if this could also be your cause but if you think it appropriate you could try it.

Turbo

@luc false contact? I've tested continuity and everything is fine.Is a false contact something different?

jay_s_uk

@Turbo yep. missed that.
You could get away increasing the current by another 100ma to 800 for both X and Y.
Rule of thumb is about 80-85% of max current, so at the moment, you are running under that

luc

@Turbo Listen ... I don't speak English well but I presented you my experience of my case where I wrote that I also did the continuity and isolation tests several times and they were always ok but your case is perhaps different.

Turbo

@luc Rereading that i see what you mean. I'll look into replacing the cables when i can get some connectors.

Bad bearing occasionally sticking? Wiring loom occasionally catching?

I'd say you should watch a print the whole way through to try and catch it in action to see what you can see.

Is it direct drive with no guide tube for the filament?

Turbo

@theruttmeister it is direct drive with a guide tube

Turbo

@Phaedrux no obvious friction occurring in the rods/bearings, they're also barely a few weeks old from mcmaster so i don't think they're bad. Swapped them just in case. Wiring loom is organized with cable chains, so no chance of that happening. Ive watched 3 1hr prints at 200% speed now with nothing happening. it really just hates me.
