Re: [Emc-users] m101 Turret Program
Doooh...I remembered this morning that anything from iocontrol.X is in user space. My original concern stemmed from an application where I was controlling an antenna rotor using "sleep" to control the timing of a 60 Hz two phase signal. The motion would be erratic depending on the system load. The rotor worked fine, but it brought to the fore, the limits of userspace timing. Though, now that I think about it, the timing for the turret is probably much more tolerant. Plus, I'll be adding feedback to compensate for variations (hopefully). I need to get this project done before senility really sets in.

Re: [Emc-users] m101 Turret Program
G4 delays in gcode and "sleep" delays in shell scripts are both non-realtime. The delay you get will always be at least .2 seconds, but may be longer.

Unfortunately, I know next to nothing about Classic Ladder, so I tend to use what I know. I have been trying to figure out if I should learn Classic Ladder, but it seems to me, that PLC's where a way to bring the old world of physical relay systems into the computer age. Since I don't come from that world, I don't see the point. Although, this statement may just go to show how little I know. > Then you could use the tool pins from emcmot to control the turret > -automating tool changes to use regular T and M codes,instead of using > M101- or you could use M101 to set a pin true to signal the ladder > program... The lathe turret tool change is not like a mill tool change. No interaction with the spindle is needed or wanted. All that happens is the turret rotates to expose the needed tool. So I'm thinking that m6 will not be used at all. Only the t word is needed, but I have not been able to find out what t actually does. (P. S. I forgot about the tool table. m6 may be needed to activate the current tool information.) Plus the actions taken when the interpreter reads a t word seem to be compiled in EMC, so are not subject to change, or at least for me at the moment. There does seem to be an "EMC from source how-to". > As I said i'm more curious then anything.

Re: [Emc-users] m101 Turret Program
Hey Kirk Just cause I'm curious, Why didn't you use classicladder to select tools from your turret? It has timers good to 100ms min. Then you could use the tool pins from emcmot to control the turret -automating tool changes to use regular T and M codes,instead of using M101- or you could use M101 to set a pin true to signal the ladder program... As I said i'm more curious then anything. Also I am Modifing Classicladder for more features -so if there is a particular missing feature I would love to know. I would bet you are just more comfortable with scripts!
