the reason I added the MPG at an early stage is so I could have an ESTOP that I could take with me round the back of the machine,
once the x axis had been proved to work a few nights ago, I then made a list of the terminals on the csmio to be used on the remaining axes y,z and a, I also colour coded them for the cat 6 wire I was using showing which terminals on the EM806 drives and double checked it, I was going to run a piece of cat 6 per drive as when I asked CSLABS why the MPG could be not I nice movement they told me it can only be noise, but I read the differential input manual and it shows its ok to use all 4 cores of cable to feed 2 drives as long as the ground at the csmio end terminated at 13,
so I set it up this way after checking my drawings and terminal numbers again.
powered up the machine and things ok checked the x axis first and fine apart from reverse, checked the channels on the plugin config for the remaining axes and they were good so I moved the z through the mach screen MPG and nice, same for the A axis, nice, no y response either direction. so I check things again and cannot find a connection problem y axis holding torque is good, the voltages from the drive pins when jogging is the same as the good axes, so I move each axis slowly with hand held MPG and notchy or lumpy in movement I don't know the best word for it, and still no y but I expected that.
I look back at the forum and there is mention about no user setup required other than plugging it in correctly, I looked at the MPG setting and it was enabled so I disabled it and instantly lost all the values, that's exactly as it happened, I spent 15 mins trying to input but couldn't remember what the settings were as I had not altered most of them so no recollection of what the initial figures were,
I have kept things tidy and written down every stage notes and not altered more than 1 thing at a time before testing it, its very time consuming but at least its traceable, but I never backed up the settings but be sure I will the instant that its back in a good state,
thanks,
