Hi I have some issues with stringing and under extrusion (top and bottom layers) on my new machine. I have a Lulzbot Mini as well and don’t have these problems.
I have tried nearly 10 times adjusting various settings and the stringing won’t stop. I am printing PPE for donation but this is really slowing down the production.
Any ideas would be appreciated and help others!
Filament is: MH Build PLA
Printer: Lulzbot Taz Workhorse
Things I have tried:
Temperature - I usually am around 205 C but when I put 205 into Cura, the printer seems to print at 195 (even though 195 is no where in any of the temperature settings). So I put it at 210 which brings it closer to 205. My initial Build Plate Temp is 55 C.
Retraction - I have experimented but landed at a Retraction Distance of 2mm and speed of 40 mm/s. It was initially at Retraction 1.75mm and a speed of 20 mm/s.
Speed - I have tried a slower speed but it doesn’t seem to make a difference. I am currently printing at:
Infill Speed (20%): 40 mm/s, Wall Speed 30 mm/s and Top/Bottom Speed: 30 mm/s. Travel Speed is 175 mm/s and the initial layer speed is 15 mm/s.
