Is that steps per inch ?
If it's steps per mm then I think you need to retune your motors from scratch.

Also the onboard graphics can be a problem unless you have a seperate PCI graphics card fitted and selected in BIOS.

Just a thought.

Go to config, ports and pins and put a check in the sherline 1/2 pulse mode box. Then try.

Tangent Corner / Interesting ?

This is an interesting eBay item perhaps.
Says it need no driver to operate from the USB with Mach3 - Is this a load of old **** or what ?

Is the stepper making a screeching sound when it is not working ?

Hi and welcome to the forum.

Go back to motor tuning and reduce you velocity settings by about 20% to 30% below the point at which they stall and screech then save the setting before proceeding to the next axis etc.

I think Hood is right and I am on the wrong track here but one thing I forgot to mention in my earlier post is that after zeroing the offsets (on the offsets page) you have to save them.

General Mach Discussion / Re: testing mach3, cannot run two axis at the same time

« on: March 28, 2011, 08:21:16 AM »

Then I think it as Hood said you need to lower your velocity settings for each axis in the motor tuning section (don't forget to save axis settings after each axis alteration).
