Thanks for the feedback Bob, We haven't put a billet in the chuck yet, or a tool in the toolpost, we're just playing around with the Codes to see what happens, we think we've allowed plenty of space between points so we shouldn't get any smashups!!

Thanks Admin,

Already downloaded this manual, and gradually working through it

The stumbling block was the LCB3 connections not being in the right place

I've made drawings of Mirac control wiring, in wmf format if anyone needs them

Mirac lathe Help

Thanks Mr Magoo, There is no Desktop tutor keypad, the keyboard is fixed to the machine on the left of the headstock, under a built-in monitor. This may be the difference between a Mirac and a Mirac PC ?. There are other keys that appear to work as I can page up & down, scroll up & down, turn coolan...

Need help with Mirac lathe

Thanks for the feed back guys, We have managed to get all components working now, the toolpost controller has a new (well, 2nd hand) mitsubishi U120 variable speed drive, and with the basic parameters set and output voltage reduced to 110vac all seems well. The computer is communicating with the LCB...

I have downloaded the available software, drawings and manuals. The machine is not a MIRACPC as shown in various pictures on this site. The...
