I've recently bought a Boxford TCL160 lathe that was already converted to Mach 3 by the previous owner. Everything seem to be working fine on it, but I noticed one thing that was wrong with it.

I noticed on the readout of the X axis that when the travel should be going X- the readout would be going X+. is there any quick way of sorting this problem out as I would really like to start using this lathe.

any help would be much appreciated.

thank you
