Title: Locating Breakout Board
Post by: BobsShop on January 13, 2007, 09:33:14 AM

I am wanting to add limit switches to my Taig 3-axis mill and cannot figure out what type of break out board to use.  I have contacted two different companies (including Bob Campbell Design which has been mentioned here as a good source) and asked about their boards, but have not received any responses (couple of messages to each over a week period).

Can anyone point me in the right direction.

Thanks

Bob @ BobsShop

I personaly don't use a breakout board. The circuit for adding limit switches is pretty simple. If your interested I can try to post the circuit. If you feel mor comfortable using a breakout board I'm sure either of the two you contacted will do the job for you.

Have used a PMDX122 on the Bridgeport CNC and its been good, costs about $80 www.pmdx.com
Have a CNC Building Blocks one for the Lathe I am doing, it has a feature I want (Index homing) Not used it yet as I am still waiting for encoders and such before I can get into the final wiring and putting together. It looks a very nice board, costs about $140 www.cncbuildingblocks.com

Graham.

I went for ones from US Digital, they left the USA on the 30th and tracking says they arrived in the UK yesterday. The plane must have gone the scenic route ;) Hopefully I will get them on Monday but the way its been going it may be next year before I eventually get them.
