Almost everything. The table and quill move as expected using the Heidenhain controller and joystick, but not the handwheel. We can create and run simple programs using the Heidenhain conversational programming mode.

We need to reassemble the machine and make many adjustments as well as establish a CAD/CAM process on a external computer.

A replacement cover for the variable speed drive is partially installed. We need to remove the cover and replace two alignment pins, then adjust the Reeves drive.

A draw bar should arrive from Kurt around 4/21. It will need to be machined to length and drilled for a pin.

The machine was wired at the factory for 460 volt 3 phase and we use 230 volt 3 phase in our shop. Ed and Dean rewired the motor and controller box, in a temporary fashion, to use 230v. It is currently using a 460 to 230 volt transformer, which will eventually be removed.

Move the automated lube system power back to the relay in the control cabinet. It is currently powered through a separate 110 v cord.

The mystery of the spindle taper has been solved. NMTB 30. We now have a good supply of tool holders.

the TNC 151 power supply failed while we were working on the machine. The problem was a bad 220uf 63 volt capacitor, which we replaced.

One half of a y axis limit switch failed. We swapped it for the other limit switch on the same axis which only needed one half working.

The homing sequence could not complete due to a bad index signal from the y axis rotary encoder. By adjusting the alignment of the encoder to the motor, the signal appeared. This adjustment may need attention in the future.
