Yea so seems like this is a classic issue with support, based on responses on my own post as well as some of the others I've read in this sub.
Is this also true with Bambu? I'll eventually buy another printer, and I don't want to deal with these shenanigans from Qidi. I just don't know if it's a "pick your poison" situation, or if there's an actual decent printer manufacturer out there.
I got a replacement hotend from Qidi for an in-warranty repair. This new hotend appears to have broken conformal coating on the back. I compared it to a brand-new hotend from Amazon (I wanted my own backup, just in case things go awry again) and there's a definite difference between the two.
Qidi tells me: "Please rest assured that our hot end is normal and there is no problem.
Regarding the issue you mentioned about the silicone detaching: our hotends undergo testing before shipment, and it is normal for the silicone in that area to detach after being heated. The hotend remains fully functional, and this will not affect performance."
I disagree. To me it appears the hotend got subjected to some serious "testing" prior to shipment, if that truly made it look the way it is.
Other owners, what do you think?
