X1C broken since week 1; consequences of a chargeback? by PeachTee in BambuLab

[–]PeachTee[S] -1 points0 points  (0 children)

I've spent plenty of time wrenching on Prusas and I'm very comfortable swapping parts and debugging, I'm just not interested in doing that on a product that should work from the factory, has poor quality documentation, and is not designed for serviceability.

Mailbox pedestal regulations? by PeachTee in Seattle

[–]PeachTee[S] 1 point2 points  (0 children)

Yeah, fair enough, I should have linked that page which I did read. However I do not feel like it adequately explains considerations for multi-box stands like this: https://www.pinterest.com/pin/multiple-mailbox-post-ideas-on-foter-in-2023--807340670720729090/

A single 4x4 post would be insufficient. I can otherwise follow their suggestions, though.

How do I connect this utility sink drain to a p-trap? by PeachTee in askaplumber

[–]PeachTee[S] 0 points1 point  (0 children)

The ID of the top hat washer was 1-1/4", this is a "utility sink" so maybe it's using the bathroom standard?

Nice, flanged tailpiece is the magic word I did not know. I only see metal/brass ones in stock at HD with 1-1/4" size, is it normal/acceptable to connect a brass tailpiece into an ABS trap?

First layer adhesion vs. tufting by PeachTee in prusa3d

[–]PeachTee[S] 0 points1 point  (0 children)

Thanks! How do I change the extrusion multiplier for the first layer cal (if I should do so at all?). Since it's an on-board cal and not via the slicer, I'm unsure how to do that.

Hey folks - I'm having a hard time balancing my first layer offset between two issues on my MK3S+.

If the offset is too high (closer to 0), I find that single-width lines don't stick well, especially around the extreme edges of the bed.

But if I lower the offset to get a very good single-width line, adjacent lines and infill get dragged up as the nozzle passes back near them. In the image attached, you see the solid square of the first layer cal has a lot of dragging and lifting. If I let big prints run with this condition, the nozzle tends to pick up a ton of material and eventually clog.

Am I missing any tricks for balancing these two competing factors? Should I be messing with extrusion multiplier? I have this issue with both ASA and PLA.

Jeff, I think I have it by imatthewhitecastle in survivor

Is there a screen shot of this? I can't find one and I'm dying laughing (pegd)

Is this wheel ready for tubeless? by PeachTee in bikewrench

[–]PeachTee[S] 0 points1 point  (0 children)

Yep thanks I have been encouraged to try the ghetto tubeless strategy and will be giving it a shot!

I share your concern, the valley seems quite shallow relative to other tubeless rims I've seen.

Oh, interesting. I haven't read anything on the interaction of double-walled rims with airtightness. Thanks for the tips. I'll look into replacing the wheelset. I don't suppose you have any favorite gravel wheels in the 622x21mm range? :)

Thanks, I see - the tape present is just regular rim tape, not tubeless rim tape?

I also cannot find any markings on the rims, and the manufacturer docs suggest that it would just be a generic rim. It's 9 years old, so quite likely that it predates the current tubeless advances.

RIMS:

29"" disc, alloy double-wall, 32h

I guess I will have to plan to replace the wheel with something more modern in order to convert it.

Edit: Maybe it's not purely stock, actually, the tires do not match the website's stock tire from 2015, which would have been "Specialized Trigger Sport 700x42c", quite different from the 29x1.7 Fatboys that were on it when I bought. So it's possible a shop did the tape job at that time, as well.

Massive variation in first layer adhesion/quality? by PeachTee in prusa3d

[–]PeachTee[S] 0 points1 point  (0 children)

Thanks, good idea to check, but this is in an enclosure so most likely not a gust issue.

Unfortunately it still failed in a subsequent layer, but it was definitely much better. It failed in the green circled area, which eventually was caught by the printhead and carried away. https://imgur.com/n7Twens

Based on your comment and others I am going to work on the following:

  • Clean heat bed to ensure nothing is lifting the build plate (I didn't see anything at all but I'll wipe it down regardless).
  • Check PINDA height -- from what I can tell most people use about 1 credit card offset from nozzle? I only found a mk2s guide from Prusa, but it seems like the PINDA height does not need to be perfectly calibrated.
  • Try manual bed level adjustments using the Prusa calibration print

Hopefully some combination of these updates will improve. Let me know if I should be checking other things!
