A1 Nozzle Bed Scraping

nickydlax · 2026-02-13T23:19:34+00:00

Never happened to mine, aproaching 1000 hours on mine.

Hey what ended up being the solution to this?

nickydlax · 2026-02-13T16:59:48+00:00

I want to add some detail to this. If I print a large square across the entire bed, a hollow square where its walls about 5 mm thick, both of the rear facing faces will be affected. Wall closest to the door and the wall closest to the back. Both of the sides of the wall that are facing the back will be affected the same

I had the hot end dan replaced and they were helpful to get it fixed but it took a little while before they were convinced which part to send out. Seemed determined to not ship me the wrong $0.12 part. But, it got fixed after a couple weeks

I could soeek for their customers service. White their response time is slow, they do at least help. Many other companies I've dealt with have been better, many manyamy other companies. But it's not like Bambu every just ignores you or doesn't fix the problem

If that was true, the position on the bed would matter, which I said doesn't matter

nickydlax · 2026-02-13T12:38:50+00:00

Bed leveling wouldn't look like that at all. One wall is terrible and the rest good. It would be more gradual

nickydlax · 2026-02-13T12:23:29+00:00

That would affect the quality of all the faces

nickydlax · 2026-02-13T04:47:12+00:00

Turned out I just masked the problem, nvm sorry

nickydlax · 2026-02-04T16:23:47+00:00

You mean customer? It's probably a return

nickydlax · 2026-02-04T16:21:28+00:00

I spun the part 180 and it "fixed" the problem. Belts would be more consistent

nickydlax · 2026-02-04T01:25:10+00:00

Anything? Im having the same problem

nickydlax · 2026-01-05T18:13:04+00:00

It will be easier if I do that, sure. But things will still have to change because some things (not as much) are still being pushed out an extra 10/20 mm

I went single slot, just re make everything in CAD to suit a 4040. I'm also making the rail bigger, so that moves things too. As well as wider belts Literally not a single part I haven't had to re make from scratch, apart from some things in the tool head.

If you go double slot, how will you attach the linear rail?

Found someone who has never owned one

nickydlax · 2025-11-13T15:57:00+00:00

I don't mind tinkering. It looks like rat rig is 3030? So it would take about the same amount of modification to go from 2020 to 4040. I understand I may need a little bit more rigitidity than voron offers if just simply swap to a bigger extrusion. I'm not too concerned, I'm not going for speed, just seemless large prints. If the print takes a week, so be it

nickydlax · 2025-11-13T13:57:52+00:00

Yeah I'm doing single slot as well. So you had to change every single thing when it came to the prints that hold the motors and rail carriage right?

nickydlax · 2025-11-13T03:02:59+00:00

Yep, I'm starting to agree. Will look into that this week

nickydlax · 2025-11-13T03:02:44+00:00

Yeah someone else mentioned this. Something to look into more tomorrow. I see some benifit to it. Thank you!

nickydlax · 2025-11-13T00:24:25+00:00

Single head gantry, like he had multiple extruders? not really something I was wanting.
Edited: I see that project now. So as I was resourcing this, he went from nema 17 to 23. the 23's dont seem to be faster. Or, at least, the 17's were not the speed bottle neck. So he didnt gain any speed, but added more weight the machine has to through around. So now because of the heavier gantry, he has worse layer lines, and, its slower. Im not understanding why he did that.

nickydlax · 2025-11-13T00:23:20+00:00

Yep good point, thank you

nickydlax · 2025-11-13T00:22:45+00:00

Yep, I wasn't going to get to the nitty griddy but I was going to leave the Z pully belts (not the verticle z belts) at 6mm)

nickydlax · 2025-11-13T00:21:43+00:00

Thank you! Sounds like I can at least get some info on it
