@user_3830817761 this has been a big issue for all of us , suggest you to sort out ASA as PETG a bit better but not good for some parts
- glue , magnets and etc will not solve the Warping which causes lifting or detaching
- Check if Your Bed is flat i found that my one was 0.5-0.6mm curved also check when heated with flat metal ruler
- ASA out of the box is not dry , make sure is well dried, sitting outside only after a day is enough to have problems. We found that our eSUN drier does not dry it unless i keep it on for 2 days and even then some moister still in, so no using the oven or the X1C drying cycle
- the other suggestions BED 110C, no AUX and no Chamber fan, part fan reduced to min , reduce print speed 70mm/S is a good but that is the last thing never go above 150mm/S
- Chamber Temp 50C+ recommended 60C/65C( almost not achievable without extra heating) soak , very slowly cooldown by leaving the bed on after the print
- insulate the machine outside helps
- PA(K) and Flow must be very well calibrated and the auto flow is not good enough
- Reduce accelerations from 10000 all the way down to 7000 even i have a profile with 3000, and mixed depending on the role
The top surface unless the warping is bad, usually points to wet filament , PA(K) or flow calibration issue - see some of the modification other people done
The 3 main design and QC problems of the X1C for ASA/ABS
- very often curved bed - with V3 it is reduced but still there( i replaced my V2 with V3 under warranty)
- Uneven heating on the plate especially edges - temp soaking, object rotation different infills helps , but better to have a cast plate on top
- Chamber it self has temperature variation with out extra heating especially in some areas - for my prints a good cover around solves it most of the time
For our ASA/ABS printing we sorted it out 90% with out special plate and without forced heating after replacing the bed and with blanket very often only for big models, but some models are still a challenge and once successful once not
For one model we added hex holes all around to reduce the tension and that sorted it , but the model allowed it
Here is the last one i am thinking to try before adding forced heating found it in the other thread :

(Warped bed :( seems like a common QC issue - #1570 by user_514568738)
I’d just like to say this ultimately solved my problem with warped bed. Thanks for the links. I like my printer again.
