This is correct, shrinking forces are fighting against bed ashesion. I use 60C and then drop it to 55 tho. On top of that you need clean bed and revisit first layer squish

You already got a good answer about lowering temp and tuning retraction. Other than that, you have underextrusion there (gaps in the flat part on the build plate). I think you should extend your calibration:

Calibrate temp - flow - retraction

To reduce stringing you want:

• lower temp
• higher retraction
• faster travel speed

Be careful with first two, if you go too far you might get a clog. Sometimes its just better to accept some stringing, but since you are at 215 I bet it can be improved quite easy

Liftoff, at least It was the best for me at the time when sync came out. I tried everything back then, but I should do it again

There is a search on bottom. Search a name then switch to community tab. Or just select it from posts.

Only thing, it cant search more than one instance at once (I think). Otherwise best app imo

Not below 100$ anymore, at least not where I live. Do my vote for 100$ used intel nuc 😄
