Hi all
I've finished building a repstrap based on the wolfstrap and printing has began.
I'm using Gen 7 1.5 electronics running the Teacup firmware and Repetier Host using slic3r 0.9.9 and I've a 0.30 mm J-Head MK5 hotend printing with 3 mm PLA.
During the printing I see rather often a big and very fast retraction of the filament where a regular retraction should suffice. When this happens the printer will continue to print but without extruding filament for quite some time and the end result is a ruined print. FYI I've slic3r configured with a 0.5 mm retraction which is sufficient for my setup.
Can anyone please try to explain what can be happening and how to solve it ?
Thanks in advance.
Michele
