So here is my print start with printbot metal. White pla 205c tge gilament get stucked to the nozzle and it get messy
Far too close to the bed, you want there to be about the thickness of a piece of paper between the nozzle and bed for the plastic to flow.
Ok so i have to increase the z? And the filament that stuck in the nozzle?maybe wrong temp?
It looks like the filament is sticking to the nozzle because it has no other place to go; I’d raise Z and see what happens before changing temps.
If you are at say Z -0.5 you’ll need to add more Z. Z -0.2 and try again. There is a ZProbe setup guide at http://help.printrbot.com/Guide/2.+Setting+Up+Your+Auto-Leveling+Probe+and+Your+First+Print/107
Also first layer should slowly!
The first layer is slow 18mm/http://s.it is printing first the brim pf a cube. The stucked filament starts from the home http://position.in other printers that i have when the nozzle goes up to leave the home position the filament stays to the bed so the nozzle is clean. Here the filent stay there and all the extra filament around it.
Are you wiping the tape down with alcohol after you apply it? Get your Z-height right, and you may still have adhesion problems if you’re not cleaning the wax off the tape.
