Re: Extrusion speed
You'd say retract_speed has something to say about the speed at which it retracts, not extrudes. In fact, the speed at which it retracts is high, it's the extruding speed that is the problem.

OK, it is a bit more complicated: Slic3r uses retract_speed from both retract and also for reversing of the retract (which was done before). For normal printing moves: * retract_speed is not used at...

That's some very useful info. I did calibrate it but I'm beginning to wonder if I used the right technique. I put a line on the filament. I then retracted it 10mm. It then put another line on the...

If the PVC is big enough, the extension below the basalt could contain the steppers. Or use larger PVC just for the 'feet'. I kinda like the two-sides and a door, though.

Why is this calle a "grounded" experimental printer? Must it be attached firmly to the ground? Must it be electrically grounded? Is GUS Simpson a type of "grounded" experimental printer? :S

usually the delta has "arms" on rods. This printer has them fixed.

Your filament may be deformed with the hobbed bolt to such extend that it wil buckle inside the bowden tube that will cause to much friction or it may cause the filament to deform to a more flat...
