Just wanted to update it might help others out. Back in November I performed the firmware update and after that update i could not get anything to stick to my textured plate finally got it working by changeing the textured “squish” in the start g-code in the slicer from -0.04 to -0.06 fixed my issue. Trued contacting Bambu only too over 2 weeks for them to reply. Which i dont even think they read my issue as there response was a very generic troubleshooting steps which was already done and in my ticket anyway. I upgraded to the new X1 custom firmware put evertrhing back to stock and now i have no issues. So yes it was a issue with the firmware so if anyone else has the same issue lokiny into your firmware.

Great idea. Did you only have issue with the textured plate? Why not also add an “if not” tectured plate to set squish of -0.02 for these plates if the issue is firmware.
Yes it was only the textured plate and that setting is in there if its not using a textured plate then it will revert back to 0.0
If you are having to adjust the Z offset for the textured plate, I would be suspect of a bent or worn nozzle tip. You should not need to adjust that distance at all.
I have had occasions where adhesion was the only thing noticeably different and ended up with a slightly bent nozzle. This would also be apparent by a slight shift in part location on the bed. Prints will not be affected. It will still give you perfect prints.
Well not for me as I said it was a firmware issue. I agree shouldnt of had to but in all reality it is no different than changeing a z-offset which is most likely a setting they changed in that firmware update. The nozzle/printer only had about 100 hours at that time, and had no issues with the cool plate, only the textured plate.

thanks for the update, its kind of interesting though. Ive hammered my 6 PEI plates for 6 months 12000 hours and as of late they have lost there fun… After much washing and IPA they still past their best. I plan this weekend to use 0000 steel wool to buff them a little, but what your saying above may help as they wear, i may try that if the steel wool doesn’t work. I do love the smooth plates but Glue annoys me yes it works perfectly but makes the prints sticky… and the amount im printing its a pain to wash them all. Ive reverted to an old tin of 3dLac which works wonders but honestly id love the PEI back, so before i buy 6 new ones im going to try the steps and see how it goes. thanks

I’ve had my PEI plates do that occasionally. I refresh them like this:
-
Scrub thoroughly using soap and water (heavy mix) and a quality scrub brush with stiff but thin bristles. This works the soap deeper into the texture and does a great job.
-
Dry thoroughly and follow with a microfiber cloth and IPA (99%). Allow to dry and then wipe residue with a dry microfiber cloth.
-
Try not to reuse your wiping rags or cloths between prints as it can transfer residue and oils back to the plate and make adhesion worse. I personally use “wipe-alls” to lean the bed. They are disposable, strong, lint free wipes and stand up well to the textured surface.
Where can that G code be found. I’m assuming in the Studio Machine settings under G-code but what line or section?
Try the Windows Snipping Tool. It’s a lot easier to use and the results are better. Also go to your Windows Settings - Ease of Use to assign the PrtScr key to the tool to make it even easier.

Not a firmware issue. Just need to clean the textured bed and scrub with good scrub pad that is slightly abrasive or magic eraser works well. Avoid ipa. It doesnt help.more squish just means elephant foot and yiu are mashing out into bed a bit harder. Scrubbing does the same.
Hmmm, Interesting.
Marking to come look at later.
Well that seemed to fix my issue.
FWIW my story is as goes.
On my X1C I haven’t updated firmware since last year. (1.04xx on the printer, 5.xx on AMS unit) Picked up a 2nd AMS unit last month (firmware on that was 6.xxx) New AMS wouldn’t read RFID tags, store entered info…etc) After a chatting back and forth with support it seemed I needed to update everything(1.07xx.) So I did on Monday evening.
Yesterday I started running a new batch of these plates and they were lifting on the corners. Naturally I went through all of the normal steps, cleaning, recalibrate…etc. Nothing was working. I just had a previous batch of these plates running on Saturday and had no problems. The only change was the update on Monday.
So thank you Navlife for posting this.

It was a firmware issue. If you dont have anything helpful to post then why post at all?
I suddenly started having adhesion issues with the textured plate on my A1 mini around that same time. I wonder if it’s related.
I found it under the A1 I checked The Mini too its the same it might work for you if you want to give it shot. I don’t have an A1 so try at your own risk haha.
One other thing to try guys is Tram the bed. i know we shouldnt with Bambu but i ended up doing it anyway, because i had to replace the signal cable as i was getting force sensor 2 errors a lot. Im not sure if any of you notice this, but i run quite a few X1C and P1S and when i run a batch of prints i notice some of them stick more than others, they all complete and work, but some are a bit more stuck on, which to me indicates bed needs tramming. I always tick bed level before every print but you can 100% tell. Bed levelling will only compensate for so much. i cant remember what the old number was but its within a range. Bambu have a bed tramming file you just load to the sd card and run through it the nozzle goes to each corner and you use the old paper method, takes about 10 mins… That being said i have now switched back to Cool Plates or smooth PEI as its a lot better at full plates where as my 15000 hours of PEI was loosing the will to live :). Cant beat a bit of Old paper levelling bring back horrific memories of me sat in my underwear struggling with my enders
