Re: Current for a Printer with 5 Nema17 Steppers
Ok maybe i just figured it out myself. Because my multimeter is very sluggish i changed the axis Speed to 5mm/min. Thats probably why the current was so low. So.. i should be fine with 7A - 10A right?

You don't drive stepper motors with dc, so they don't draw 1.7A/Phase (its another miss leading stepper motor number for worsts case condition, ie DC) I cant recall the maths of it, but what I can say...

1.7A per stepper happens at a much lower coil voltage than the common 12V and the driver output works in PWM mode. So the average ( DC-equivalent ) current asked from the PSU is 5-6 times lower than...

View ArticleRe: Current for a Printer with 5 Nema17 Steppers
The 1.7A label rating of the motor is a kind of maximum rating, and NOT the value it should run at, not even something you should aim for. Most likely should make a driver setting at 0.7-1.0 amp or...

Some questions: 1. Why are you using external stepper drivers at all, when it appears to me that the electronics you are using is capable of driving those motors directly? 2. Why are you driving 1.68A...

In my opinion, interfering with step or dir lines, with anything, might not be a good idea. Any logic you put there will just add delay for rise time, logic processing and output, and that could be /...
