Hello, I've been lurking in the shadows for a bit. I'm looking to upgrade my 2 axis Bridgeport Series II with a 3rd Z axis control. Currently my Z axis has a linear glass encoder.
I aquired a Z axis quill drive made by Elrod Machine, http://www.elrodmachine.com/CNC_Z_Axis_Quill_Drive.htm. Its an older model which doesn't include the integrated glass scale so I figure I'll attach a rotary encoder to the end of the ball screw ont eh quill drive. In fact this is exactly how the Anilam Z quill drive is built.
So heres my challenge. I need to replace the glass scale with the rotary encoder and the electrical output of the rotary encoder needs to be exactly the same as the glass sclaes as I don't want to have to change anything on the control, an Anilam Crusader M three axis control. The Anilam glass scale on the machine now is a "System D-10". The Z quill drive takes 5 revolution per inch.
This kinda sounds like one of the word problems back in elemetry school. I'd appreciate your thoughts on this.
Thanks,
Michael
