Re: Stepper motor doesn't work
Update: I managed to use motor with test code:), but in marlin it doesn't work. It turn when I command 0.1, but in bigger value, like 10, only noise.

Hi, I start to test x axis in pronterface it is good, motor is cold, but stepstick with heatsink is hot. Is it normal? Maybe I use too high current?

Ehhh.... is there obvious heat? It sounds like it's a heat issue. The defect follows the motor, not the axis. If it was an issue with the software, when you switch the x and y axis, it shouldn't...

Possibly your G code tries to move the motors faster than the Pronterface jog buttons and the motors can't handle it. Have a look at the F codes to see what speed it is trying to move and try jogging...

I have this 6 lead Stepper motor 6 volts 0.6 amp. jAB1Uz2.jpg this is the lead pic PSguz5m.jpg can i use this for the RAMPS 1.4 board? I know that usual motors are 4 leads. but is there any way for me...

Using an unipolar 6-pin stepper in bipolar 4-pin mode is always possible. You just have to find out which pins are the center tabs and leave them unconnected. For this you best measure with a...

View Article3 phase stepper with 1000 encoder
Hello, I have a question that I cant seem to get my head around, would appreciate some help. I have a 1.2 angle 3 phase stepper with 1000 line encoder. This means my motor does 300 steps for each full...

Isn't the microstepping applied to a sequence through all (3 in your case!) coils? In this case, a complete microstepping cycle would be applied to 3*1.2deg = 3.6deg, which comes to 100 cylces per...

I dont really know how that works, I am currently reading on it but, even if thats true, 1000 cpr isnt divisable by 3.6 degree...or is it not calculated that way?

I am designing a test rig where a uniform (but programmable) torque load is required, and moved intermittently at 60-120rpm. Can a stepper be used as this variable torque load ? It would be rotated by...

Steppers are designed to keep position, not to keep speed or torque. A simple DC motor would meet your requirements better.

They do run hot, if they over heat they shut down from their internal thermal protection. You should check you vref anyways.

Nice. I like a lot. What sort of step/mm setting does that work out to be?

I started my tests having just 2x encoder resolution and that turned out to be 31.189 steps/mm. It does not sound like much, but I reckon these values are actually accurate, while microsteps do no...

Impressive demonstration! For the future I think you can drop that part with calculating from wanted position to step pulses in Marlin, then back to wanted position in your stepper driver Arduino....

I have just tested it and I realized I was provided wrong information. The seller claimed the encoder had 888 lines but it turns out this is wrong. I guess it is something around 450. Anyway, the...
