To my understanding this could be my setup of the motors but when I initially got my machine moving yesterday I moved all the motors fine with no issue so not 100% sure.

At the moment I am just copying what others are telling me to put in mach3 settings but I would like to know what I am inputting and why so that I can better understand my machine.
Is there anywhere particular I can look up for research material or download a book etc. and or is there sites to avoid as known for giving incorrect information?

If you are interested my settings on the motors are on the attachment, I am not sure what else you require other than I am using 220v and all three motors have jammed.
PS the temperature in my garage has dropped to 3 degrees I do not know if this makes any difference in the structure/performance of the machine itself.

Kind Regards Graham
The high pitched noise can come from stepper stalling. Try reduce acceleration to half and see if it goes away. Could also be that there are some mechanical issues, so the movement is stopped and because of too low torque, the stepper stalls and you get the high pitch noise. Very difficult to say without more details. The settings you show does not say much about the steppers and the current/voltage you feed the steppers with, or which type of steppers they are. The speed you have configured seems pretty low, but perhaps that's the maximum for your machine, perhaps it can be increased with better drivers and higher voltage.

I have not used Mach3 for quite a while now, but the Internet is full of documentation about how to set it up and which parameter is what. I think Mach3 is THE best documented CNC software in the world, so it should not be difficult to find plenty very well written and detailed pdf documents about it. I know I had a lot of that when I was still using Mach3 and all came from the Internet.
