Holy crap, one A4988 adjustment video where somebody actually speaks! Thanks!

[@davelane1773]

Very well explained. Your content is top notch. Thanks for all you do.

[@windowsraspberrypicomputer5577]

You saved me thanks took me a while to find such simple information.

[@Kady3DPrinting]

The best video for adjusting

[@businessuser8640]

TOM HANKS, dude. Your explanation was perf.

[@aaronnewman2]

If you cant measure voltage with a Arduino uno CNC shield, your Arduino needs to be powered on... Just in case this helps somebody, that was my issue.

Please help the problem of drawing at an angle of 45 degrees and I tried hard but could not how to solve the problem if it is possible to clarify with the picture. Thank you

Meus motores aquecem muito, uso DRV8825 NEMA 1.5a, Conf. o vref 1.05a 70% (0,55 xy e dobrado 0,77 no Z, esquenta muito, nao consigo colocar a mao nos motores ???? HELP

[@freddiemeinertzhagen]

This video is incredibly useful

[@andrevoerman1483]

Very clear! even for a beginner like me

[@corlissmedia2.0]

This is a great video! Thank you!

I saw another video saying you want to make sure the motor connected to board as well before powering the board or you can fry the drivers. That was for an Arduino CNC shield and DRV8825 drivers though. kzbin.info/www/bejne/hZfchWSuib92bNE

I recently went through this process on my Maker Select v2. The formula used was current (amps) x 8 x sense resistor value (.1). Then that number was multiplied by .9 to get 90% power. I'm setting my Voron 2.1 up now (using the recommended 2a stepperonline motors w/ 4988 drivers (sense resistor r100) and was wondering if the 1.4 vref value I got would do the trick?

[@OleksandrDiedov]

On Voron 2.1 and preferred motors (from official BoM) you need only 1.2-1.4A on 12v and near 0.9A for 24v.

[@iiianydayiii]

@@OleksandrDiedov Nice, thanks

[@KK3DTechnology]

input voltage 24 volt. Vreferenc is depend on voltage..?

[@CanuckCreator]

input voltage does not affect setting your drivers Vref

[@KK3DTechnology]

@@CanuckCreator ok 👍🏻

[@KK3DTechnology]

@@CanuckCreator 12 or 24 volt system which one is best

[@TheShazzbag]

Does klipper need to be pre installed on the Mega?

[@CanuckCreator]

No. No software installed on the controller is required to set the vref this way

[@leonhuynh3074]

What is 0.8 mean?

[@jamesmurraldeo7624]

8 x 0.1
