Indeed, all manicurists loves me!!😍🥰

do you happen to know what resistance (R1) is because it's burnt on my device and i can't tell it's Ohm

[@viocaia]

Sorry but I don't have it on my bench, it's back to work

Hi there and thanks for the video! My machine works on maximum rotations, you cannot change the speed (the diode lights up). Do you have a guess what's wrong? Thanks in advance!

[@viocaia]

That should be a final Mosfet in short...so all the voltage goes to the motor. Replace the transistor.

[@MagicATR]

​@@viocaiaThe transistor that sits on the radiator? bdw93c?

[@viocaia]

@@MagicATR I believe so...if you have a multimeter on resistance/diode mode, you should see a short in between legs

[@viocaia]

@@MagicATR Yep, that's Darlington transistor, not mosfet like I thought before.I never encounter such a problem.

thank you for the video. it was usefull, but the locking system with the 2 so called doughnut shaped parts are actually assymetric, and it have a marking on it. I think that was an S letter, which have to look in the handlebar's direction. I assembled it first in reverse direction and it were unable to lock the milling heads

Hi! What oil are you using, and which one would you also recommend for efiles?

[@viocaia]

Any oil for fine mechanism will do the job, like the one for sawing machines or watches...you can easily find some in any auto part shop

[@amusetherest]

@@viocaiathank you!
