cannot get prints to stick
I have had my printer for almost a year now and I still can't figure out what I did wrong. I have to either; a.) resand the bed every couple of prints, b.) use a fresh glue coating every print, c.) recalibrate every filament change or a long time of idle. I know people like Prusa are using the printers close to 24/7 and printing well I feel the printer should not require this constantly. I have tried using closer z-axis adjustment, replacing the PEI sheet, and changing to polymer bearings. anyone have the same problem or know what could cause this?
p.s. I have used both pla and abs and must use an adhesive for both.

Re: cannot get prints to stick
Aside from a good Live Z setting, a very clean PEI sheet (clean with pure acetone) is required. I find PLA sticks VERY well with these two things.

Re: cannot get prints to stick
Did this recently start happening with the new firmware update? I was having issues with the first layer after I updated the firmware and I eventually found out it was because I was printing the first layer too fast. I had the first layer speed set at 50% so before with 60mm/s regular print speeds I was having 30mm/s first layer but with the new firmware I'm printing at 100-120mm/s which resulted in first layer speeds of 50-60mm/s causing the filament to curl up on the first layer. Once I lowered the first layer speed the filament stuck much better. The only issue I have now is due to the bed being bent in the front left causing the first layer height to be off in that corner of the bed.
