IF YOU DO NOT LIKE THIS MONITOR FOR ANY REASON, RETURN IT BACK FOR A REFUND OF YOUR WINNING BID (see below).
For sale is a Heidenhain Monitor BE 211 B. It came from my Bridgeport Interact mill that I retrofitted to EMC2 and Linux (see www.linuxcnc.org). Here's what I know about this monitor: when I bought the mill for $500, the control was bad. I invited a tech from a firm that specializes in Bridgeport repairs. What we found was that the right lights would not come up on the Heidenhain control and the display was blank. We tried two more displays that the tech brought in, and all of them were blank.
So: I have never seen this display run. I suspect that it may work. I feel good enough about it to offer you the following warranty: If you do not like this item for any reason, within 7 days of receipt, you can return it to me for a refund of your winning bid. You will have to PAY SHIPPING BOTH WAYS and pack carefully.
