Almost everything. The table and quill move as expected using the Heidenhain controller, joystick and 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.

Y axis ball screw cover is bent and not sliding properly. It should be removed and replaced (or bent straight). Removal is difficult because it is bent. This could require removing the table, which is heavy.

Find a process for backing up and restoring system parameters. Update: Parameters can be accessed by pressing MOD repeatedly until you are prompted to enter a Code, which is 95148. The EXT key allows import of parameters from this screen, but apparently not export.

In some cases, there isn't direct translation. The front panel buttons are labeled for conversational language.

Move the Heidenhain power source back to the Bridgeport control.

The Handwheel uses a Heidenhain HR 150.001 5000 F4 controller, Id.Nr. 220 954 01, S.Nr. 1300302 A. It is very fragile, using a glass encoder wheel. We have determined that the light bulb that illuminates the wheel, triggering a signal from the photocells, has burned out. This will either need replacement, or we will need a new encoder.

Clean up the BP service manual scans and add the document to the wiki.

The TNC 151 can be programmed in Heidenhain conversational language, or G-code. By default, the keypad labels indicate their functions in conversational mode. In G-code mode, the keypad buttons take on different meanings. The controller originally came with a keypad overlay, attached by magnets, that had different labels for the buttons for use with G-code. We don't have this. Improvising something would be helpful.

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.

''' Emulator '''
A TNC 151 emulator that runs under Windows is available for download at http://www.cnc-developments.fsnet.co.uk/ Note that this definitely supports Conversational mode, but it is unclear whether it supports G-code programming. It appears to be shareware, with some features limited.
