    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

            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.

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

                @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

                  @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.

                    @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?

                        Isolate, substitute, verify.

                            @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.
