Hi, The machine is at the Isle of Man College. The switches operate with a metal plate over them, but not when the axis is driven over them. Checking out your links next Thanks.

Hi again, we have removed the bellows and covers and cleared the machine of all debris. we have checked the boards and ribbon connectors and cannot see anything wrong. The Y and Z proximity detectors are working in reverse, manually operating them causes the lights to go off on the debug board.chang...

Can I just clarify where the homing switches are ? We have found a switch at the top of the Z axis and the inner end of the Y axis. On the machine debug panel both Z and Y homing switch lights are on all the time. Operating either of the switches manually causes the emergency stop light to come on a...

Just to clarify:- The machine would not home. The new software was to enable me run the tests described in your previous link. I can jog the machine with the secret button and the axis move the correct amount in the following directions: Page up key Z moves up Left arrow key moves table right Down a...

On the control panel a small green Y and Z are displayed all the time, which from the link you posted me should only be shown in a test ...

Z+ head moves up correctly
X- table moves to the right
Y- table moves to the back
could it still be the homing switches ?

Thanks for the info. Our version of the software is too old. I have ordered a site licence of the new version and then I will give it another try.

Yes. The axis move the correct direction and amount until all axis display zero on the control panel, but the machine is not at its home position

Tried the VME settting but does not work as well as the basic TRIAC machine setting. I am unable to read the original floppy disc as it seems to want to re-format.

We have a 1998 Triac which has not been used for 4 years. The computer which ran the software (VR Milling) has crashed. We have re-installed the software on a new computer running windows XP professional and the programming and simulations work fine. I can drive the Triac, using the secret button, i...
