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. Ryan contacted Heidenhain, who does not repair this, and said "this was a very particular lamp/lens assembly, with the lamp focused through the lens in a particular way – not exactly a flashlight bulb." Heidenhain has a replacement: "ID. Nr. 540940-07. It is the current version of the HR 150. List Price $594.00" At Dean's request, Ryan shipped the encoder to Oracle Encoder Service on 5/6/15 for repair; quote was $290.

Dave will order a design computer for the milling machine. The computer will be set up on the desk to the right of the mill. We don't have a network cable run to this area, but it should be easy to add this under the cat walk.

Investigate the air leak at the back of the machine. It appears to be leaking at the filter drain. Could be a missing O ring or a cracked bowl.
