OK, before anybody goes to a lot of trouble to explain the finer points of adding a fourth axis...! Here's the answer: I stumbled across Ray Henry's (virtual) conversation with a dude whose username is chinamill, which cleared up just about all of my confusion. Thanks, Ray!
Now I'm at the point of having the A axis present and accounted for, I have Astep and Adir coming out of pins 8 and 9, and the HAL config looks great. And I get almost immediate following errors on joint 3, the fourth axis! Aaaaargh. It's been a while since I've done battle with this issue; I copied one of the existing axis configs and changed LINEAR to ANGULAR, and UNITS to 1, keeping all other parameters the same. I figured since the X axis has been working fine for quite a while now, the A axis would too with the same maxvel, accel etc. But no. Is there anything fundamentally different about an angular axis that might account for the following errors? I have tried lots of different FERRORS, etc. in an effort to get around them (as I have many times before) but so far, no luck. thanks again, 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.
