What CNC Machine is this?

For those three pictures on the axis settings - I'd be setting the pulse-width to 5us in the first instance. The reason? - okay, I don't know what stepper drivers you're using but many/most use opto-isolated inputs for the step/dir signals, and /cheap/ opto-isolators can have slow response-times in the order of 3-4us (actually, worst-case performance can exceed 5us on many devices). Some are faster, but typically cheaper devices are relatively slow. Changing the pulse-width to the slowest possible (5us) gives the best possible chance for the pulse signal to be recognised by the stepper driver.

Thanks for all answers but i burned the bob when try to measure volt from spindle port, all output is dead so this shitty obsolete things is going to garbage or saving the rest for someone how need it later.

I order this instead http://shop.cncdrive.com/index.php?productID=1098 and keep writing in this post http://www.mycncuk.com/threads/15333...for-avid-drive beacuse i will same time upgrade the machine, the 10mm rack inside the alu profiles is not a good idea to save, its bad aligned and get big backslash on some part and to hard fitted on some.
