I would think that build quality (especially the strength of the inter-layer bonding) could depend strongly on the ambient temperature in the build volume. I've tried searching for information on that...

Hi Tesseract What is your esteps setting in config.h? If you are still using my value that may be your issue. I have 1/32 drivers so you would need to halve my value for 1/16 on Pololu., assuming you...

Does each unit use its own stepper motors or could you use 1 set of motors of beefy motors for the whole lot? Very nice design! EDIT: first time I watched the vid I didn't look carefully and didn't...

What's the cost impact of making the rods larger in diameter? If it's modest, bumping up the diameter is a pretty easy decision.
View ArticleRe: LISA Simpson
The rods are $53 more. The nuts are the same cost. The upsized 1607 bearings are $10 more.

I am pretty sure that the machine in the vid has only 1 set of steppers. I haven't calculated anything but I assume that you can get away with normal NEMA17.

Stepper motors are noisy. The step frequency is normally right across the audible range. Having said that if you feel your printer is too noisy you can try these things: Put some squares of carpet or...

@cozmicray: A linear rod would completely change the geometry. It would cause a cascade of changes that would essentially turn this back into a regular Rostock with lead screws instead of a belt. BTW,...

if that were the case how would the motors be, meaning they may not extrude but would I be able to be turn the shaft by hand without any resistance or would it be hard to move?
