driver voltage
hello friends I would like to know what are the voltages of the a20m drivers with board Gt2560 V3.0 the drivers are allegro A4988 with resistance R200 since and to turn them in days past and were unconfigured reading on the internet I found a formula
Vref = Imax (8 x Rf)
Vref = 1Amp (8x0.2)
Vref = 1amp (1.6) x 70%
Vref = 1.12
this formula is well applied to all drivers or I could pass the correct voltages of each driver please help
Axis X:
Axis Y:
Axis Z:
Extruder 0:
Extruder 1:
I moved them and I did not take the precaution of taking these voltages before making the movement
I thank you because I have my a20m unarmed because I could not with the voltages

Re: Drivers Voltage
Hello.
You must read the value of the RF resistor from the elements used. These modules are mounted in very different versions. I have seen with 0.1 and 0.2 ohm resistors. There are also versions without them.
My doubts aroused only one record.

I agree with the rest.
On the forum I help to use the rod, I don't give fish.

Re: Drivers Voltage
Hi friend
reading the resistance is R200 this means it is 0.2 and 70% is for full sptep but should remove the jumpers in this case we handle 1/16 step or the voltage for the drivers should be 1.6v according to the table conversion.
the table says
full step without jumpers multiply by 70%
1/16 step with all the jumpers is not modified anything would be 1.6v but I think that 1.6v for the drivers is a lot of voltage what I would like to know is if someone who has an A20M can take the voltages to the drivers and I can happen because mine are bad
