[Emc-users] Two motors, one axis
I know this has been covered before, but I cannot find it... How do you connect two pins to the same signal to be able to, for instance, use two stepper motors on the same axis?

You can use either net: net signalname pin-writer pin-reader1 pind-reader2 or net again: net signalname pin-writer pin-reader1 net signalname pin-reader2 or linksp: net signalname pin-writer pin-reader1 linksp signalname pin-reader2 or linkps: net signalname pin-writer pin-reader1 linkps pin-reader2 signalname or only linksp: newsig signalname type linksp signalname pin-writer linksp signalname pin-reader1 linksp signalname pin-reader2 .. and probably a couple other ways too ;) Regards, Alex - Original Message - From: Len Shelton l...@probotix.com To: 'Enhanced Machine Controller (EMC)' emc-users@lists.sourceforge.net Sent: Tuesday, January 06, 2009 8:32 PM Subject: [Emc-users] Two motors, one axis I know this has been covered before, but I cannot find it...

How do you connect two pins to the same signal to be able to, for instance, use two stepper motors on the same axis? You can do this in one or more 'net' commands: On one line: net Xstep stepgen.0.out = parport.0.pin-02-out parport.0.pin-08-out On multiple lines (just one of many variations): net Xstep stepgen.0.out = parport.0.pin-02-out net Xstep = parport.0.pin-08-out For a given signal (Xstep in this example) you can have only one source (a hal OUT pin, stepgen.0.out in this example), and as many readers as you like (a hal IN pin, parport.0.pin-##-out in this example). (For so-called IO pins like index-enable, the rule is a little different and I won't try to summarise it for fear I'll get it wrong) Jeff -- Check out the new SourceForge.net Marketplace.
