Product Review: Maker Farm i3 Prusa 8"

[MeoWorks]

DrLuigi,

It might just be the sensitivity of the recording but I can definitely recommend adjusting the pots again to get the stepper motor noise down. My Prusa sits on a sheet of neoprene I cut from an old laptop sleeve and it doesn't make a sound aside from some nice robotic motor noises from the steppers. Then again, I do print very slowly, 20mm/s on all fronts and have adjusted settings in my firmware that deal with jerk speed, so my steppers don't work as hard and vibration is minimal. My thinking is, why print fast and have it look ok when you can print slow and have it look fantastic!

Well i already thought to get my multimeter up and check its voltage, But i just cant seem to find a decent picture that tells me where i have to measure it with,

And what Voltage it should have.

So far i have let it standard and didnt mess with the pot, so that could help me with the noise.

You probably know this but just do "tiny" adjustments with the pots. Don't make big turns or you can really mess them up. They don't bottom out and if you go past a specific point it's hard to get them back to where you started. That's a caution I read.

Good point MeoWorks about the stepper pots. I found that my motors were running very hot right out of the box. I adjusted them back about 1/8th of a turn and now they run at about 140F instead of 180F. I think they are quieter too since that adjustment.
