Re: Heated Enclosure

Here's some feedback on the heated enclosure so far. Basically you never need to run the hair dryer because the machine heats the cabinet up enough as it is. In fact, if you want to run with the door closed you actually need to use the cooling fan to keep it in a range that won't overheat the steppe...

Re: Printing Spare Parts

The multiplier crushes all the drive gear depth, filament hardness, printing speed, shrinkage, and other imponderables into a single number that works reasonably well. Make sense? Actually, yes! It's like one big fudge factor that compensates for all the unknown variables. I guess the key word here...

Re: Printing Spare Parts

The originals are printed in ABS, and yes, what you're looking for is the extruder multiplier value. I don't know what it usually is for ABS, but for all the filaments I've used it has invariably landed in the ~0.88 range. You can do a full calibration test if you want, by getting one of the thin-w...

Re: Printing Spare Parts

Would that one allow the use of Ninjaflex filament? I've read where the standard V3b won't work with Ninjaflex. Not sure where you read that...I used NinjaFlex on a V3B just fine. Go slow & hot (40mm/sec, 250C) and up your extrusion multiplier to about 120%. The PTFE tube likes to fall over but the...

Re: Printing Spare Parts

The press fit on the stock model is super tight. Try this model for a slightly less punishing fit: http://www.thingiverse.com/thing:433292 It has some extra modifications as well, most notably the filament guide tube and more cone on the hot end intake. Would that one allow the use of Ninjaflex fil...

Printing Spare Parts

Does anyone know what material the extruder drive block that comes with the M2 is printed from? I printed one out of ABS but I don't think the original is ABS. The holes and slots are very slightly undersized in my print, which can mostly be fixed by re-drilling them to the correct size but that slo...

Re: Heated Enclosure

How much time do you have to put into it? Do you just load up a big hopper with pellets at the beginning of the day and then it's hands-off the rest of the time or is it one of those things you have to keep checking on?

Re: Heated Enclosure

Guys the Filastruder does a great job on consistency, it just sucks for extrusion speed. I get 1.71mm all day long... ovality is 0.02. I wonder if speed and consistency are tradeoffs. The Filibot Wee has a much higher extrusion rate than the Filastruder, it would be interesting to know how consiste...

Re: Mounting M2?

I was kind of wondering this too. The rubber feet on the machine allow it to shake a lot more during fast movements like fills than if it were bolted to a solid surface. The question then is that bad or good?

Re: Heated Enclosure

Given that one of the common complaints with cheap commercial filament is inconsistent diameter it would make sense that home brew filament would suffer from this defect to an even greater degree. If a company that mass produces it with more accurate machines can't hold good tolerance than someone w...
