H.O. & all
with Henrik's help I've been making some progress on my mill. I did have two axis running (X & Y) last week using the uhu chip. I've had a reoccurring problem with poor/no communication between the axes & mach3 and or erratic movement under the terminal program over the life of the project. Henrik gave me some suggestions & using his guidance I got the X & Y axes working well in mach3/uhu chip. I was working in the Z axis & managed to short out the Y drive killing it.....
so after repairing two drives over the weekend I was in the shop today and now have the X & Z axes up and some sort of problem with the Y axis wanting to run away. When I quit to grab a bite to eat I had decided I needed to check my Y encoder cable to see if I've broke a wire or shorted two or more at the drive end (quite a sharp bend there)
I've had the X & Y running using the module and basically just got them rough tuned using the module (before I smoked the Y axis). I had the road runner program running in mach3 and so far what I'm seeing is two significant differences between the uhu & modules. first & what I was hoping for, the module handles 500, 1000 & 2000 count X 4 encoders w/4000rpm servos with no problem, very consistent control . what I wasn't expecting but am pleasantly pleased with is that with the module the servos sound so smooth & as though they are effortlessly going through the motion. when using the uhu chip I thought the servos sounded very good. with the module, the servos have a real different, quiet, free (?) sense about them. I know I'm being very subjective in this post but just wanted to share my experiences so far.
