I reached milestone today when I got the tool change command to work - sort of. The "iocontrol.0.tool.*" pins were not connected correctly. My toolchange.ngc is now called correctly and it activates the carousel component as expected. The first pocket trigger still generates problems since the carousel continue to think it has gone when step further than it really has. After homing it stops at pocket #1 and the carousel.0.current-position also indicates #1. But it's after that things gets a bit strange. Issuing T5 M6 will move the turret to the physical pocket #4 whereas carousel.0.current-position will indicate #6.
Every tool change from there on will offset the commanded tool pocket compared to the actual tool pocket by one, where the physical pocket is lagging the commanded tool. If I try to shift just one tool forward it has the same result as when I tried to jog one position earlier - it just goes back and forth within the same pocket, although increasing carousel.0.current-position by one . To make it change one physical position forwards I thus have to command a tool that is two positions ahead. Adding "+ 1" to the target on line 235 in carousel.comp takes care of the problem from a physical aspect but carousel.0.pocket-number won't match carousel.0.current-position afterwards as a result of that change. Due to that carousel.0.ready will not go high and therefore the subroutine will timeout. I haven't found out how to deduct "one" from carousel.0.pocket-number variable but if I do think things will match. Not a global solution but it might be good enough for me. *edit* I got your last answer right before sending this so I will evaluate your response and see what I can come up with. I didn't know that it wasn't necessary to remap to make this work. I followed your advice to take a look at the sim.axis.vismach.VMC_toolchange example in a thread at the forum. But that part seems to work anyway. Regards, Andreas Den sön 10 jan. 2021 kl 10:43 skrev Andreas Linnarsson < andreas.linnars...@gmail.com>: > Andy: Here's my first shot at using the HAL scope.
