Brains Development / Jogging from a shuttle control via brain
« on: February 14, 2017, 10:54:06 AM »
I have an old jog/shuttle wheel from a video recorder connected via PoKeys55 to Mach3.
I've got the jog wheel working as MPG1 without much difficulty - I aim to use that for very fine positioning.
I've written a brain to interpret the 4 inputs from the shuttle section - that seems to be working (have so far coded only the first 2 positions in each direction to prove the concept). My problem is in what to set/trigger based on the interpreted shuttle wheel position. I find the names for the various buttons, DROs etc. related to jogging somewhat cryptic.
I'd like to trigger a continuous jog which gets faster as wheel twisted further, which stops when wheel released.
So far I've not been able to work out a generic jog+, or jog- that I can set (to affect axis selected from screen - or buttons later).
Slow Jog% seems to behave correctly when viewing the brain, but not when viewing the jog control on screen.
I'm getting frustrated - not entirely clear if some of the issue may be with the brain, or if it's all about choosing correct jog mode and settings. Is there a very clear explanation available of the numerous jog related items within Mach3?
I'm familiar with control systems in general, but have limited experience with Mach3.
