Vref for the stock stepper drivers

[wotor]

Hi everyone. Can someone please tell me correct vref for stock stepper drivers?(A4988ET) I got a new A10m and motors are getting quite hot. I check vref with multimeter and I got 1-1.1V on drivers. I contacted geeetech support, but they didn't answer. My resistors are R200.

Thanks for the reply vert.
I set all drivers today to value 0.9V
Motors are quite warm but not hot, haven't seen any of skipping steps yet. I ordered tmc2208 and I hope you can help me in future with fine tuning my machine.

Check out his YouTube channel. He’s got a lot of useful vids on our printers! I think it’s vertabreaker something or other. Anywho he’s a huge help to the geeetech community! And I’ll thank him once more! Thanks again for all your awesome work and the help you’ve given me personally.
