My current lathe is a Colchester Bantam, having discovered that the Boxford AUD was not up to a decent cut , and a decent Myford super seven had reached serious big bucks by that stage if you wanted a gearbox and a cross feed,
I find that the bantam is a BIG little lathe capable of some serious work and comes complete with all the bells and whistles .(but we digress)

I am not yet confident enough to hack my Bantam about , at least not until I have become confident with the CNC process.
Hence the reason for buying the TCL. As they say ,"any old bike is good to practice on"

So having arrived at the stage where you have persuaded me to chuck the Boxford boards away, yet we think we can retain the lenze spindle controls , I am trying to establish whether I need to keep he processor board . It looks to me as if the relays which call the Lenze controller to run FWD, REV, and the latching functions may be within the processor board . Or have I got this wrong??

I am also trying to get my head around the pin signals to the BOB in relation to the switching functions of the manual control board . Each button there seems to switch a control voltage to earth . Is this a parallel arrangement to the control voltages utilised by the CNC software so could both working options .
