Re: Cheap unipolar NEMA 17 motors in Québec
Me again... I found an other way to plug the wires of this stepper motor, and like this, theorically, it is 4 times stronger. In fact, I have no way to test it but it is way stronger. Ok, basically in...

Hello there, I’m doing some experiment based on leading screw motion. My issue is to find a Nema 17 stepper motor that provide high RPM (3.000) in order to obtain fast movements. The configuration is:...

Typical motor for this is any motor rated with 1-2-3-(max 4) ohms coil resistance and (min 1)-1.2-1.5++A current. The voltage is the product of the two numbers, so if its only two given, you can...

Hello everyone my Z axis is somehow not moving and i tried to switch the motors and figured out, that that was not the problem so it has to be in the firmware. I tried the same with x and y and those...

So I have been building a reprap and have been having problems with the motors and think I have isolated my problem. I decided to start my motors fresh so I set the firmware over and set the vref to...

- The fact that when motor stops you can not turn the shaft by hand, that is absolutely normal, that is actually how it is supposed to work. What happens is that the stepper motor holds its position....

Hello it looks like some of what I said was not very clear, When I was adjusting the pot on the driver chip I had to put it all the way to around maximum power around 1.2v vref to get the shaft to...

I dont know that how much is VOLTAGE this model of stepper motor, anyone can tell to me ? [www.huaning.com] >>> model 17hs0002-11 Can i use this motor with ramps?
View ArticleRe: stepper motor 17hs0002-11
Simple multiplication: Voltage = Resistance * Current = phase resistance 30 ohms * rated current 0.4A => 30ohms*0.4amps = 12V You could try use that motor, but will not perform that good because...

QuoteThe "axis step per mm" does not affect torque in any way. This setting only determines the length of the move. If you set it to 10, it will move some distance, if you set it to 20 it will move...

Quotetyscof I get that it doesn't effect the torque but when I set the values really low like 20 the motor will move and I wont be able to stop it like I could before. It has the torque that it should...

Thanks NoobMan But i use A4988 / DRV8825 Stepper Motor Driver Carrier, High Current that it operates from 8.2 – 45 V [www.pololu.com] . I use ramps1.4 for 3d dlp printer.I think that i dont need high...

"High" speed is a relative term, but what is low or normal speed for other type of motors, for stepper motors would be high speed, so i guess you do need that. Because you do want your motors to still...

I use 12v power supply with 5 ampers. I decide that use this stepper motor. model 42D4002 2.9 V 1.2 A 2.41 ohm Is that suitable for DRV8825?
View ArticleRe: stepper motor 17hs0002-11
Yes that should be ok. With the note that 1.2A is more of a minimum, something like 1.5-2.0A would be sort of better. Although in practice with the pot on the driver will probably adjust current peak...
