    Default Help with erratic Z position after tool change.

    DIY router: My tool change position is Z2. During run when M6 is called tool moves to Z2. After tool change it should return to previous position. PROBLEM: Tool moves to Z~=1, DRO shows Z~=-14. Any ideas?

    Not sure about DRO.
    But if it is CNC control, then we can set gear ratio by parameters to correct it.

    It is not consistent. All axis respond correctly when I run simple exercise code (+5' -5 loop). Not just with the tool change. Sometimes when jogging with a 1"increment, it will move only half the distance but the DRO says it moved about ten times that.
