Jog issue
« on: July 01, 2015, 07:43:23 PM »
I'll do my best to describe this issue I am having.

I have been getting my Chinese mill setup, didn't have to many issues till now. I went setup backlash because I was having issues cutting round circle. Turns out though my Y axis is not jogging correctly. I set the mill up to push the 1" (25mm) dial indicator. I back the mill up then push into the meter to remove any backlash, then I use jog (step) to move 1 mm and mach3 says it moved 1mm but it actually only moves on the Y axis .7mm.

So I went into the "Settings" Tab And did "Set steps per unit" and it does the same thing, mach then resets my motor setting but It still not right. In fact the amount of movement is never consistent, sometimes .7mm other times .69. My meter might be a little flaky but its random enough that I know I have problem. The X axis has no problems, works as expected and all the backlash and everything is taken care of. Its just the Y.

Any pointer or material to review you could suggest I would be real grateful.

Thanks
Matt

I figured this one out. The machine actually has an OS an it needs to be tuned as well. I completely missed it.
