It doesn't say anywhere in the linuxcnc manual for classic ladder - but is there a limit for the compare block to just 2 compares? ie..
I had this in the compare %IW0<%W0,&%IW0>0,&IW0<7 For the life of me the logic just wasn't working. Finally I put it in 2 separate compares.. %IW0<%W0 in one.. followed by %IW0>0,&IW0<7 This worked as expected.. BTW - the old emco turret with no feedback should work pretty darn well with a little ladder logic.. Only 1 output. (logic 0 runs the turret into the pawl through a current limiting resistor.. logic 1 runs the turret clockwise to the next tool.) https://www.youtube.com/watch?v=JGGPob1iKj8 The original Emco compact 5 CNC, when you would call a tool - say you are at tool 1 and going to tool 3 - would stop at tool 2 and index. (it stops at every tool location between the one it was at and the one you called) I think this was probably convenience as you need 2 different time delays - the initial one to go to the next one.. (slightly longer than every pocket after the first..) I am currently using 2.2 seconds for the first tool - 1.8 seconds for every tool after. kinda neat. _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
