Got my ATC installed and ready for software. So excited to get this up and going. ![IMG_2636](https://us1.discourse-cdn.com/flex022/uploads/onefinitycnc/original/3X/6/a/6a421bb746b0c4cd1e05ee2ac83c565c963514cd.jpeg) I do have one question! What is the Z20 spacer plate for? Is that for those that install the ATC on the front of the table? I understand it’s a spacer for the Z20. ![IMG_2635](https://us1.discourse-cdn.com/flex022/uploads/onefinitycnc/original/3X/0/1/016b983503b24c2eb177d13f411abec1337e6c19.jpeg) Thanks Chris ---

It goes behind the z slider sandwhiched between it and the x gantry. It pushes the spindle forward when used with a qcw adapter (which is not used in your picture). ---

Ok, that is what I was thinking. Thank You
