I needed to change the computer running mach3 USB ( R3.043.066) licensed.  I downloaded same version on new HP computer ( Windows 10), configured ports & pins, but when I setup Motor Tuning, there was no blue lines.  I selected X axis, when I imput veloc. and accel, they disappear if I touch slider bar.  When I imput steps and touch slider bar, veloc and accel disappear...
I have looked at old settings and see no difference, even downloaded mach3 again.  Motor outputs were the same.
I have not connected to cnc machine yet, but I was able to set up Mach3 before.
What am I missing?
