Hi all,

I built my first 3 axis machine a few months back and have had great fun playing with it. I was able to set up EMC and get the thing to draw on paper without any problems. After not having used the machine for a month or two now, I'm having all sorts of trouble trying to touch off on the Z axis. I home all axis and then touch off the x and y axis, lower the z axis onto the paper face and then touch off at 0. The problem I'm having, is that the Z axis is nearly always shown to be -1.6792 below the workpiece hight, so when I run the machine, the Z axis floats 1.6792 above the workpiece.

My machine uses a Geckodrive G540 with 3 x 387 oz-in steppers.

I can't remember changing anything apart from home/limit inputs in the configuration.

Was just wondering if anyone has had this problem or might be able to point me in the right direction?

Regards,
Damon

Problem now fixed. Simply created a new config and all is well. Not sure what the problem was, but at least now I have my machine back.

regards,
Damon
