YES! Just did 3200 steps per rev - dont have the 2000 setting - much much smoother!
How can I increase the speed of rotation independently of the number of steps? I changed "velocity" but it does not look like it is going faster...

Thank you so much for your help, I was really getting annoyed with this!

Good morning Hood - I's sorry but I don't know what Sherline mode is... newbie!

Also, noticed that in Motor Tuning, Step Pulse and Dir Pulse were both at 0 uS...
changed Step Pulse to 4 or 5 - now the stepping is much better and regular, but still slow, and there are lot of vibrations...

getting there... maybe...?

thanks

Thomas

I did change "step per" to 400 for the X-axis in the Motor Tuning... I get small irregular steps, like before...

very frustrating! Don't know what do do nest...

many thanks

I am test benching: microsteps at 400/rev (0.9 degrees),nothing connected to the motor.

power supply can either be 5V near the Estop, or USB.

Just tried with 5V... now I am getting confused. With the 5V-non-USB, the stepper does not work, but the very small led next to the X connector block still blinks a bit.
Now I went back to USB powering, I get the same -no stepper, small led blinking.... restarted Mach3... same, now the stepper does not even stutters...

Hi there,

I tried 2-3, 2-4,2-5...2-17 and they all gave the same result as the "correct" 2-14: slow, irregular steps (about 2 Hz)

any suggestions?

many thanks

Will try that!

The breakout board is powered via USB (signal through DB25), so yes, it should be powered.

I have my stepper set at 400 pulse per rev (angle 0.9). There are no screws or anything on the stepper yet

many thanks

Thomas

Just tried this:

I disabled all axis except X, then for X tried again changing pins from 2 and 14 to 3 and 16, then 7 and 8 - in this case nothing worked at all

Hi Hood,

Sorry I don't understand this:
>Looks ok with the exception of Y axis ins being the opposite way round, well depends which part of the document you look at

Anyway at the moment I am only using the X axis. Shall I disable all of them except X, then for X try again 2 and 14, then 3 and 16, then 7 and 8?
Is this correct?

many thanks

Thomas
