Hi everyone, Well I've finally gotten around to adding a rudimentary 4th axis to my minimill. I've just started trying to figure out how to make AXIS and EMC2 spin it, so far without success. (For some reason, after I've banged my head against a config issue long enough to get something going, I immediately start using the darn machine and after a year or so, I'm practically starting over in trying to understand it the next time!)
Anyway, I _thought_ all I would have to do was add a fourth axis description to my .ini file, and a few new signals and pins to my HAL file. A quick look at stepper_xyza.hal ought to make things clear. Ha! Not so much, as it turns out. There are a whole lot of things in stepper_xyza.hal that aren't in standard_pinout.hal (like differentiators and enable signals) and I can't for the life of me figure out why. A couple of clumsy attempts to reference both hal files in my .ini file failed, as did attempts to add stuff like Avel and Apos signals/pins to standard_pinout. So I guess my question is: what basic steps should I shoot for in adding an A axis to an XYZ minimill? Somehow adding stuff to standard_pinout appeals more to me, since I (thought) I understood how that all went together! I added a limit switch signal/pin etc. and messed around with HALscope, and all of that ended up working, so I _was_ feeling pretty good about my ability to extend EMC2. I'd really like to pull that off again! thanks, Pat =================== Patrick Ferrick Town of Webb School Main Street Old Forge, NY 13420 (315) 369-3222 (315) 369-6216 (fax) ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
