I've just been trying to tune my gantry setup and I have had a few problems. I am using 2.5.
I am using gantrykins with XYZX. I am trying to set up my limits for for speed on my Z axis of 180ipm. In joint mode, jogging around, it seems to obey this. When I switch to world it doesn't listen to that limit anymore and I can (try to) jog it up to my MAX_LINEAR_VELOCITY = 6.00 in my [TRAJ] in my ini. This will throw a joint error. It seems like I lose some flexibility when using gantrykins vs just slaving the drives together (although I would like to be able to home both X1 and X2 independently). Is there a way to home the drives and then run it as if they were slaved? And then some other problems are my somewhat poor base period (this is the reason my Z can't go about about 180ipm on a screw drive). I have a 3 GHz pentium 4. Tried the SMI fix, an external video card,and disabling all the power saving stuff in the bios and can't seem to get it below ~45000 jitter worst case. I've thought about getting one of those little atom boards to improve the stepping, or should I get one of those mesa cards I keep seeing you guys use (like 5i25? at $90 that would be as cheap as a atom board). Could I plug that directly into my C10 breakout board from keling (http://www.kelinginc.com/c10.pdf)? Probably should have broken that up into a couple posts... but thanks for any help.
