prusa mk3s: first layer lifting in a ripping fashion

[thatgerhard]

I'm printing using PETG, The build plate is clean and I also used glue stick for adhesion. I've done the 1st layer calibration and that was fine too, it's when its extended printing that this happens. Any help would be appreciated.

The only time I get is when I try to 3D Print the first layer too fast.
Sometimes 1st and 2nd layers then it will finish 3D printing perfectly.

Thanks for the reply. I'm going to try that and report back.

Just out of interest, at what speed do you normally print at once the 1st layers are down? Oh so far so good on the print the 1st 4 layers are done and nothing lifted yet. Yay! Thanks for the info earlier.

You are welcome.

I have my 3D printer setup to print the first layer at 32% then the remaining layers at 72-82%.

This is relative to which slicer I am using Cura 15.04.6 prints at what I consider a normal speed however Prusa Slicer seems to print at slower speeds.
Could be how my configuration speeds are setup.
