Stuart could you please send me a PM with chris radeks email unless of course he sees it here. I have no way of contacting him..
just to confirm does your toolchanger calculate the shortest path and move the chain magazine that way to get to the required pocket? And also I am a little stuck now actually getting the handshaking with linuxcnc working I know how to get a S32 number into classic ladder. to tell classic ladder which pocket to choose and I have me ladder logic to not more until I send a tool prepare signal from linuxcnc. But I don't actually know how the linuxcnc signals work properly. I am just guessing. I know how to send a tool prepared signal from my ladder logic back to linuxcnc to tell it that the tool is prepared and the toolchange can start. So I would really appreciate some help on the actual signals. From the sound of it you have used linuxcnc for ages so know all about it. Even if you shared me your tool change hal file that may be enough. I just want to check what actual io control signals I need to connect for each part and if there is anything i need to look out for I think this infomation is not machine specific any random position toolchanger would need to get this handshaking working. regards Andrew On Thu, Apr 16, 2020 at 9:01 AM Stuart Stevenson <[email protected]> wrote: > Andrew, > > Here is a machine of the same make and type as the one I had. > > https://www.dropbox.com/s/45pwhcvfqr38dfd/Used-Enshu-VMC.jpg?dl=0 > > It is somewhat different than your machine.
