Bryce, I would (and did) avoid using Gantrykins. It is rife with bugs (like ignoring MAX_VELOCITY, or try jogging with keyboard keys in Manual Tab/World Mode and over 488ipm - gives immediate fault but in Joint Mode/Manual Tab, can jog at any speed) and/or gotchas (World Mode only supports continuous jogging not incremental, and I guarantee you will screw up and jog in Joint Mode). We spent a long time trying to get Gantrykins to behave including modifying Axis to switch to World Mode automatically, but ultimately gave up and are very happy with our trivkins configuration. See documentation here: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?GantryPlasmaMachine
I reported a number of bugs on the mailing list back in Dec/Jan/Feb related to Gantrykins and World/Joint mode and was ultimately convinced to just use trivkins. If I were you I'd save myself the frustration. Wait, I was you and I didn't! Go ahead and experience the frustration and then switch ;-) Or as we say, Learn from the mistakes of other's by repeating them yourself! BTW, good name. 10 years ago I named my son Bryce :-) Tom On May 29, 2012, at 2:45 PM, Bryce Johnson wrote: > That is true, but then I will lose the ability to square off my gantry when > I do homing.
