Hi, we just got a new 4x8 China router (from a US seller) which fortunately has Mach3 on it (not Syntec like our older router).  The Y axis had been set up reversed so it was cutting mirror images of our parts, and I'm in the middle of sorting that all out.  I believe I've got the axis issue resolved, but now the tool change function is a bit wonky.   I've run other machines with Mach3 in the past (a K2 router and a Tormach mill), but I don't have any programming/troubleshooting experience with it, just button pushing. 

Anyway, it's a 8 tool bar type ATC, and 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 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?
Thanks,
James
