All still manual other than a jury rigged x feed i put together. The Z axis is heavy to wind manually so I'm thinking struts would help till i get it converted.

Hi Derek
Yes I found the head very stiff in use and I was concerned that the stepper motor would have problems, this is the gas strut I fitted http://www.wdscomponents.com/en-gb/g...50/c-340/p-887 you will need to slect the best lenght for you mill
It has a valve to adjust the gas pressure so you can balance the strut against the weight of the head. the system has been fitted for about 6 years now and is working very well.

Hope this helps
