Prusa i3 MK2S print problem
Hello! I recently bought the Prusa MK2S kit and I'm having some trouble with it
So sometimes the 1.75mm PLA filament is not sticking to the bed so I tried using glue stick, but it still doesn't work.
We've tried calibrating the z axis using live Z axis and moving the PINDA.
Also we tried cleaning up the bed with alcohol.
The settings to print PLA was...
Nozzle Temp : 215 C
Bed Temp : 55 C
Here are some photos how it failed

Maybe try to clean the bed with acetone, it worked quite impressively for me.
Also maybe printing a little bit lower in temperature (210, 205) ?

I'd try the Z Calibration print several times - perhaps from a cold start and a warm start to see if heat changes the PINDA level.
Looks very much like you're first layer isn't getting "planted" well.
If you do the Z Calibration print and can easily scratch the test extrusion off the bed, then you may need to go back and get it better adjusted.
I had to play with it for a while (well, not that long) to get it to a point where it was sticking consistently but yet not squishing down too much.
From what I've read (and I'm definitely no expert), if the PINDA is too high, it will work, but be inconsistent so one time you'll get a good initial Z level and another time you won't.
