Yes, I had problems with losing the Z-position due to the computer I was initially using. I had a 1 GHz AMD machine which could not seem to keep-up with Mach2 demands. I chased the problem for quite a while and tried a lot of different things with the electronics with an attempt to solve the problem. I finally switched computers, and the problem disappeared. I am now using a 1.4 GHz Intel Pentium 4 machine and it runs it flawlessly. It was strange that I only lost location on the Z-Axis though; and never on the X or Y. If you own a faster computer, I would try swapping them and see if the problem disappears as it did in my case. |
