Many thanks for the reply Adrian,
No air on my TCL160(1994) so manual only for the chuck.
I have a limit switch on the body of the cabinet which is activated by a rod on the Z Axis. Clearly this serves to prevent the tool post clouting the chuck. (Good idea)
I read somewhere that depressing both Left & Right feed together that the machine should execute a 'Homing' action.
This didn't work for me unless I misunderstood the methodology. Any Ideas ?
Should there also be a Limit /Homing switch for the X axis ?
I purchased a spare set of boards which were removed from a non turret machine together with a Small format Motherboard SBC-GX1 complete with compact flash with Software 4.3.1 installed.
I wonder whether this software can be upgraded to V5 or even 6. Any ideas on this ?
The PC motherboard I'm told was fitted inside a TCL160 ? There is no such board in mine. Did earlier machines have a PC inside ???
For the moment, I will try and get the native software running and see exactly what the machine is capable of doing.
I will then convert it as you have done so if you have any schematics of your arrangement or any pictures that you'd care to share I would be very grateful.
Meanwhile
Best regards
