Hey everyone,
I am at the end of my ATC design and have been trying to decide what to do for driving the tool carosel. I would prefer to use a geneva mechanism for spinning it for more accurate indexing of the tools but have not yet done any looking into how I would control it with Mach. several things come to mind that may or may not be an issue. how to have mach understand which tool position it needs to go to when called in a tool change command. hmm.. that was a bit vague, let me clarify, if i were using a belt drive setup, i would do it by degrees, my tool changer is a 12 tool unit so i would have tool 1 be 0 degrees and each proceeding tool would be +30 degrees. so:
T1 - 0
T2 - 30
T3 - 60
T4 - 90... and so on until you are back around at 0
with the geneva wheel, would you do it the same way and just account for each rotation of the stepper to be a block of 30 degrees? any help or direction on this would be greatly appreciated!
Thanks!
Chris
