3d models do not adhere to the bed

My 3d models are not adhering to the bed, I’m using PLA filament at a temperature of 210 degrees and all my print are taking off the bed

Do you have the thermistor properly positioned?

I had to tweak the right Z height for a good fix on the BuildTak. Closer meant better attachment. I was printing PLA at 200°c.

thank you everyone, problem solved, it took only a better Z calibration

Glad to hear your up and running!!

Same problem here, i have recalibrate the Z-axis and now all prints are great!

did you do anything special on top of the procedure in the instruction manual?
