Hey andy I have the classic ladder program I have made working fine to chose select the correct pocket and I am getting pretty used to classic ladder now.
currently my formulas for choosing direction are simply comparing the current pocket number to the required pocket number (C1 is the current toolnumber. C2 is the required toolnumber. %C1.V>%C2.V ----------------------------------set MAG fwd %C1.V<%C2.V ----------------------------------set MAG REV %C1.V=%C2.V ------------------------------------reset coils (turn off magazine motor) and tell linux cnc this is slightly better than just going in forward direction but not that much better. it works pretty good if the numbers are 4 and 5 but not if they are 23 and 0 the magazine goes the long way round and takes ages. How would I use your Hal component with this as you say all I want it to do it chose the correct direction for the shortest path.. I could probably do it within classic ladder if I could work out the equations. But I am definitely open to using the hal component if needed. I am just a little confused how it all works regards Andrew On Wed, Apr 15, 2020 at 4:49 AM andy pugh <bodge...@gmail.com> wrote: > On Tue, 14 Apr 2020 at 12:02, andrew beck <andrewbeck0...@gmail.com> > wrote: > > > I don't quite understand if the carousel component can interlock the > motors > > so I don't turn both fwd and rev contactors on at the same time for > > example.
