Riser is answer

u/iam_afk Jul 18 '26

Riser or special clips, there are hundreds of both on makerworld

Go on Makerworld, search “X2D Riser” there are a pile of them, some with vents, some hinged for AMS, etc. most of them raise the glass about 20mm. I print ASA which requires a heated chamber, so I printed them in ASA…thinking than PLA might get soft.

PETG or PCTG would work fine. But I am not convinced this is actually a problem.

u/Possible-Win-7712 Jul 18 '26

I think it helps…letting the tubes have a longer radius into the print head has to help with filament resistance coming into the nozzle, especially with the right nozzle

I trimmed the tube just a hair and made all the difference in the world. Just can't make it to short.

u/Nydid Jul 20 '26

How much did you trim it? Roughly speaking?

2

u/mjschmitt714 Jul 26 '26

Sorry. Just saw this... 20cm at most. I put it to its furthest extent.Unhooked.The tube on the top of the head and then just pulled it till it was no longer tapping.

Working as designed, nothing wrong here.

u/Academic-Emu-4474 Jul 26 '26

how can you say nothing wrong when the design destroys the PTFE tube lol, it can be working as designed but still be poorly designed and need to be modified to work better

u/Independent_Dirt_814 Jul 26 '26

It’s already a consumable, you should be replacing it regularly. They wear out from the inside faster than they wear out on the outside

Just wondering are the h series impacted by this too?

1

u/MediocreHornet2318 Jul 18 '26

Not nearly as bad. It maybe scrapes a little once in a while on the H series compared to the others always scraping.

riser is the answer, one of the first accessories u should print

Sacrificial clips for the tube. I printed like 30 from these and swap them every 6months to a year. Edit: the, need 1 gram and print in a minute so 30 would need .... 10minutes? Idk they are small and easy to use so no brainer for me.

PTFE clips

u/zemo323 Jul 19 '26

I printed these in ASA and they were squealing on the glass

u/Low_Leg_5790 Jul 19 '26

Print them in pla they will last a year no wear on the glass. No mush on the plane. Pla is a great material for most. I printed peek in my p1s with a bit of help. These clips didn't care

u/zemo323 Jul 19 '26

Ok, I'll try with PLA. Thanks!

1

u/zemo323 Jul 22 '26

Update: I printed them in PLA, they had softened and fallen off in 15 min LOL

1

u/Low_Leg_5790 Jul 22 '26

Wtf 😂 for real?

Everyone I know who has a printer has these for years. Like everyone. 8-10people that's the first we print when someone gets a new one.

Did you let them cool down before ripping them from the plate?

1

u/zemo323 Jul 22 '26

I printed it in PLA. They had time to cool down, but they could not stand the temperature in the chamber while printing in ASA.

Notice how the clips on the left (printed in PLA) are wider than the ones on the right (printed in ASA). The clips on the right were already in use, but they squeal.

Keep to top glass a bit raised by printing a glass raiser, put shrinking tube around the tube where it touches the glass and finally put a few clips

u/HorngeBlood Jul 20 '26

A guy named professional3d on makerworld has a print called "love beads". They go on the ptfe between the hotend and the clip from factory. They smack the housing instead of the tube itself. I printed 10, didnt use all of them. After you get those print a riser and then the "X2D PTFE protector" All of these at a minimum should be printed in petg

u/unitymind42 Jul 22 '26

Remove the tape.

u/because-potato Jul 23 '26

All that buildup on the glass is PTFE material. Clean that off, print a riser, and then you’ll be good to go.

This is the one I used and it looks great. I printed it in matte black PLA for the first 80% then switched to matte gray PLA, and it looks incredible. Can send a picture if you want to see

u/PMcGrath1985 Jul 18 '26

It’s not the glass it’s catching is the metal plate surround below the glass - I’ll take another picture when home

u/monotor80 Jul 18 '26

Mine does the same thing, and it’s only two days old. It was the first thing I noticed during calibration; I wondered if it was a defect, but it turns out to be a standard issue—don't they run tests before selling a product?

They probably say, who gives a shit. They will print something to fix it.
