signori,buonasera a tutti. Volevo porvi un quesito: ho costruito una fresa cnc interfacciata al pc con una scheda tb6560 e mach3. ora, ho comprato un estrusore per stampare in 3d ma non so come fare la calibrazione essendo senza firmware… avete qualche consiglio?grazie.
The short answer is that you need to make sure that the amount of filament that it pulls is the amount requested. There is probably a steps per mm setting in the firmware.

There is a page somewhere on the internet with a bunch of pictures that show what different problems look like.
If these links are not enough, do an internet search or go to https://plus.google.com/communities/117814474100552114108
Good luck!
