Thank you for doing this Andy, I will shortly be attempting an LCNC retrofit on an Emco 320 and was wondering how I was going to manage the toolchanger. I think this will really help. Cheers, Pete On 17/03/2022 01:25, andy pugh wrote: On Mon, 14 Jun 2021 at 16:33, Nicklas SB Karlsson wro

Hi Rita Now that you are retired, I thought you might be interested in this email. The group is heavily involved with open source machining. As this posting indicates, they are doing serious work. This isn't exactly the kind of woodworking that you have expressed an interest in, but it isn't

My carousel have an ordinary encoder used to sense angle of carousel wheel with an index impulse. A digital output signal rotate carousel, index pulse must occur before sensed value is valid and have to wait until a given position depending on selected tool to turn off rotation of carousel. D
