I’m always looking for ways to evaluate the fitness of our plastruder designs. Today I let the plastruder sit at full operating temp (200C for the green PLA 4042D) for two and half hours. It just sat there oozing PLA while I took a nap! Then, upon awakening, I clicked on Build and set it loose to print this 80mm x 80mm x 50mm monster block (a 3.5 hour print job). The filament drive is just the plain old 2 RPM DC motor with the aluminum pulley – nothing fancy. I think the nozzle is a 0.4mm but it may be 0.35mm. And, the temp for the heated build platform was set to 50C.

After 3 hours and 21 minutes the 80mm x 80mm x 50mm block finished – no issues. And, the dimensions of the actual object were just about spot-on: X = 80mm, Z (minus the raft) = 50mm, only Y is a little under at 79.5mm. Does this qualify for the longest print in the mBot HOF (not sure what standard configuration settings mean)?


I think this design would leave the extruder on most of the time. Maybe take this design and punch some random holes in it so the extruder is forced to go on and off? Our standard nozzle seemed to extrude into air indefinitely, but die when doing a part.
Otherwise it looks great.
Tempting to get one :)
Hey Chris -
mb v1.4 and ext v1.8. I’ve finally managed to get v2 to compile so I’ll like be experimenting with it (i won’t use it if I can’t compile it :) ummm…i’m using SF from 7/09! I’ve got newer versions installed but for some reason, I still use this version. Feedrate and travel feedrate are 60mm/s.Rick
A few questions if you don’t mind answering:
- What version of the firmware are you running? I tried 2.0 but its been acting kind of odd.
- What version/release of skeinforge are you using?
- What feedrate are you using?
Thanks

Yes, a hybrid.
Nice, I guess this was made using the hybrid PTFE/PEEK insulator?
