    Default New 4x8 ATC Router- Reversed a backwards axis- now what?

    Alright, so our new 4x8 China router shipped with Mach3 installed. I've used Mach3 before on other routers and mills, but haven't done any setup/config modification on them, just button pushing.

    My situation is as follows- The Y axis came reversed, so it's making mirror images of the desired parts. under Config/Ports and Pins/Motor Outputs I changed the DirLowActive from X'd to Checked, and that now has the machine jogging in the correct directions, though it homes in the wrong direction (as expected) and gets confused.

    So my question is- What needs changing now to reflect the corrected axis? Can I just do the math for all the home switches, soft stops, ATC tool holder and tool touch off locations, and call it good? If so, would I just mirror those points around the midpoint of the work envelope or what? Or should I just pretend the old settings never existed and act as if I'm setting up a home build (experimentally determine everything by jogging around)? Have I missed any components that'll give me trouble?

    Thanks, and sorry if I'm not being terribly clear- I'm far from computer literate!

    Thanks Daniel! It now homes the correct direction (Y positive end on this machine) but when it hits the switch, it errors out with with a "Limits Re-engaged" message. Won't reset to let me jog off it, have to shut down and gently move the head with the power off.

    Never seen that one are the soft limits on

    It does it whether the soft limits are on or off. Currently off.

    Default Re: New 4x8 ATC Router- Reversed a backwards axis- now what?

    OK I got that sorted by changing the home offset to reflect the fact that it's at the positive side of the axis. Made good progress so far, thanks! It now homes without error.

    I've updated the M6Start.m1s macro to reflect the new Y locations for the tool holders, but I'm now getting an error when it's most of the way through a tool change. Example- T1 is in the spindle. I input T3 M6 into MDI, press start. T1 returns to the T1 fork, releases as normal. Head goes over to T3 fork, picks up T3 as expected, the head raises. At this point, I get an error message that says "Wait Brush Position Limit Signal" and 3 or 4 seconds later it changes the error message to EStop Button Pressed.

    The ATC did work fine without this error before I corrected the reversed axis, and the only changes to the M6Start.m1s file were the "TxYpos =" values. I've copied the file below. Any ideas?
