Usually only one axis skips steps, especially since the MK4 has collision detection. A shift in both axes would rather indicate a steel sheet shift imo

Fantastic! Glad you got it in the end

Did you losen the idler tension screws? TPE requires that the tension is very very light otherwise it tends to buckle around the gear before entering the nozzle tube. Reducing retractions to a minimum is also always a good idea, as well as limiting the max flow rate.

I’m afraid I can’t recommend anything as I’ve never had issues with this, so I never really researched it. But if the banding frequency changes from print to print, then an issue with the Z axis is unlikely

What is driving the bed height? Lead screws? Check if they are straight and/or wobble around as they turn. Any imprecision in bed height due to mechanical issues with the Z axis would also translate into perimeter width variations.

I can only guess the print orientation but it looks like curling to me. Basically on that side, the part cooling fan (or lack thereof) is making the plastic of overhangs curl more than on the opposite side which gives you this bad surface finish. Otherwise maybe a retraction issue but that would probably show in other places too (oozing).

And install python and install those dependencies before you can even run the thing

Yeah their security track record as of late is pretty bad…

Interesting, that would confirm the pressure advance as the likely culprit (speed and acceleration are taken into account in the algo). Maybe your slicer has a bug related to this? If changing the value wildly does not improve or worsen it, then it might not be calculating what it’s supposed to. Can you try another slicer?

All seems to indicate something related to pressure advance, whereby the printer thinks it needs to extrude less because of some pressure buildup but it underestimates how much is really needed. Does it happen if you print slowly? E.g max 15 mm/s or less.

I reported the bug to Proton support and they said they are investigating but suggested I uninstall and reinstall the extension. I did and lo, my forms started working again. I can recommend you try to uninstall and reinstall too (disabling it was not enough).

Note that the “plus” suffix doesn’t hide your real email, that’s a small but notable difference. I could well see websites parsing for +… patterns and removing them before selling your data.

That’s cool! I’ve used enough raspberry pi’s over the years to know that SD cards, even if industrial grade are likely to fail at some point so I try to avoid booting from them. eMMC would be much better but sometimes a pain to flash depending on the tooling available. Having a SATA port would allow to use HDDs which provide a lot of capacity for cheap. I guess the processor needs to be an Amlogic for the best media experience?

How does storage look/work with a SBC? Do you have to boot off of an SD card? Any support for sata drives?

This is mostly a cooling issue. Not being able to solidify the plastic fast enough after it’s been deposited.

Have you seen how fast printers with stepper motors can get? They print benchies in less than 3 minutes. The bottleneck is not the motion system, it’s either the hot-end or the part cooling. Also stepper are super accurate and very flexible. Drivers are advanced and can tune for torque, speed, sound etc. Collision detection and skipped step detection is also a thing.

Sounds like you found a bug, it’s worth submitting to SuperSlicer

I’ve never used podman but always wondered if it was able to use the host’s network stack to perform things like sending ICMP packets.

Been using this for a few months and now I don’t know how I lived without it before.
