How to clean glass bed? (CR6 SE)



  • Hi guys some insight based on what I've seen dont use IPA I did and my bed adhesion is no where near as good as it was I actually fitted pei sheet and back to 100% print quality i fitted the pei to the glass bed as the base underneath was not level but trust me it made a huge improvement. If you've already used IPA assume the adhesion is not going to be anywhere near as good wish I had know this before but happy now with my first layers again.

    I was convinced the abl wasn't doing anything or something weird but it ended up being adhesion issues creatality I recommend you take the comment of the manual.



  • @rjamison said in How to clean glass bed? (CR6 SE):

    Still no explanation how IPA damages them, either

    If you use a light-coloured cloth with your IPA, you can see a yellow residue coming off the bed onto the cloth. That's the coating that makes it so you don't have to mess around with glue or hairspryay with the glass.
    Before using IPA on mine (as I'm used to with glass beds, and as the manual recommends) I actually had pretty good adhesion. Now it's like printing on hardware store glass plates back in the day, but it has a weird texture and the creality logo on it 😞



  • @3dala +1 on sharing experience.

    I finally heard back from support, who said my glass beds weren't damaged enough for them to replace. Still no explanation how IPA damages them, either. Just an admonishing about using water to clean them.



  • @3dala I ordered 3 different brands of flex beds and one 3rd party glass one, I'll definitely share my experiences once they arrive and I have a chance to put them through some prints. πŸ‘



  • @shinmai thanks a lot. if you can recommend a 3rd party bed, would be great if you can share your experience.



  • Creality is not responsive at all (haven't gotten a single reply to my e-mail yet, it's been a week) but if you don't mind paying for the replacement out of your own pocket, the beds are now available on the usual sites (AliExpress et al).

    Personally going with a 3rd party platform since Creality doesn't seem to be addressing customer support enquiries about this at all.



  • Hi,
    i think my glass bed is damged too, because i cleaned it like described in the manual.
    I got a lot of adhesion issues.
    Now i tried to clean with water, but still the same problems.

    Is there any chance to get a new one?



  • @admin @admin cr-6manual pg3
    So where can we claim for a replacement glass platform, to replace one that's been damaged by following the user manual to the letter?



  • @admin I'm interested in a possible free replacement as well. The user manual literally says to use Alcohol. ! There is is RIGHT THERE https://imgur.com/a/hbe5SUD



  • @admin or is there a way we can repair the print surface?



  • @admin Since following the instructions in the manual damages the glass print bed, I (and I presume others) would like Creality to replace damaged print beds. How do we go this?



  • Dear @rjamison

    I have double-checked this, It is not wiped with IPA, it can be wiped with detergent or water, not with ethanol or isopropyl alcohol, which will damage the surface coating of the glass.



  • My new bed changed from Black color to Brownish color after cleaning with the alcohol. Adhesion has gone in reverse. Instead of not adhering, the prints are getting to the point of almost not coming off. Should I just flip the glass over and use the non coated side?



  • @admin i don't understand. Are you now saying that cleaning the bed with IPA doesn't cause damage?



  • Dear @rjamison

    I send your question to our engineer, it seems that Wiping after power off has no effect.

    The 3rd page of the user manual (if the cover page is page 1) specifically says "Use glass cleaner or isopropyl alcohol to clean the print surface before every print for consistent results".

    To be clear, it says to do this "before every print".

    I've already done quite a few prints to test different filaments, and have been cleaning the surface between each print AS INSTRUCTED. I have also noticed a degradation in bed adhesion, which I thought was due to some of the filaments I was testing, but now Creality is telling me that it is because I used IPA to clean it.

    If using IPA is the reason for the decreased bed adhesion, then I would appreciate a new glass print bed to replace the one damaged by following the instructions in the user manual.



  • Bit worrying to find this - I've been using IPA and a micro-fiber cloth to clean between prints and it seems to be working fine... but if it's doing long term damage to the plate that would be great to know.



  • @admin ?



  • Really glad I came across this post, I was trying to print a thin card and had bed adhesion issues just in one spot, dead center. The only thing I could conclude is that this was due to fingerprints because I usually wipe away the glob left at the start of a print. I typically print on a glass mirror and clean it with glasses wipes, so having no idea what coating is on the bed of the CR6 I would have potentially done the same. From this post I concluded that what ever the dots are, it’s not friendly to alcohol, so I washed it with some dish soap and warm water and adhesion is working well again.



  • @admin the manual specifically lists isopropyl alcohol as one of the cleaning agents to use on the build plate. If this is actually damaging the plate surface, the manual does need to be changed.

    How is it damaging the plate? As in - what is happening to the plate, and what are the consequences of it? Are they purely cosmetic, or somehow impacting proper function of the bed?
