Topic: Number 166 up and running
Finished my Filastruder on Sunday and already extruded all the included plastic. Works fine after fixing some minor issues:
Didn't cover the brass nozzle with insulation at first, resulting in some temperature problems. Couldn't even reach 180 C.
The motor torque tightened the pipe in the flange and almost spilled the contents of the hopper on the floor... had to take the bolts off and reorient it. How are everyone's hoppers vertical, have they just been adjusted to vertical even though the feed hole in the pipe isn't pointing straight up?
After fixing these it worked fine. I used some ideas from Thingiverse to make a more compact setup (I'm always critically low on tabletop real estate...)
I have a 2.8 mm hole in the nozzle and got 2.85+-0.05 filament when letting it pile on the floor randomly from a height of 150 cm, at temperature of 185 C.
The Sestos controller needed to have the Ctrl set to 2 in the settings to enter autotune mode. After autotuning, the temperature is very stable (+-0.2 C or so).
Is the published output rate of 1 kg per abour 24 hours for 1.75 mm filament? I'm making 3 mm filament and the rate seemed to be quite a bit higher than that.
I found granules of Bayblend T85 on ebay.de, and should be getting 20 kg of those shortly. It's an ABS-polycarbonate blend. Will report on how it works (or doesn't).
