Can't find a usable temperature for PLA I have a Monoprice MP10 Mini, a cut-down Creality CR-10 with lobotomized firmware. Heated bed.

I'm trying to do PLA prints, but have been unable to find a usable temperature.

If I set the temperatures (either nozzle or bed) too low, the initial raft layers don't stick, the print shrivels up, and the result is a tangle.

If I set the temperatures high enough to allow initial sticking, the raft prints okay, but after that the filament leaks out of the nozzle during long moves producing strings (only a little unsightly when outside the print area, but causing bumps when moves over the build and eventually the nozzle knocks into them) and all solid flat areas (ceilings/floors) warp.

If I start with a high temp but reduce it during the print, the layers stop sticking to each other, solid areas still warp, and the printer eventually fails to extrude anything (presumably the filament congeals inside the extruder or tube, that's very unpleasant to recover from, fortunately I have some cleaning filament).

Tried with multiple types of filament and multiple models (from thingiverse, converted into gcode using cura 3.6)

What should I be trying?
First, you shouldn't need a raft for most PLA prints. That will help you get better bed adhesion at lower temperatures.

Second, you can reduce the stringing by increasing travel speeds (120&nbsp;mm/s is not too fast) and a small amount of retraction: around 1.5&nbsp;mm for direct drive and 5-6&nbsp;mm for bowden.

With those settings, you should be able to print most PLA with a bed at anywhere from 50-60&nbsp;&deg;C and an extruder at anywhere from 190 to 215&nbsp;&deg;C.
