Thanks Dave, I'd be interrested to know how it turns out, keep us posted. I don't use the AH-HA software. Just the controller black box. I use Microsystems of ...
Mariss, Has there been any change in your G320/G340 Fault/Reset Manager? I breadboard your circuit & couldn't get it to work. I didn't know that HEF4001B had...
Mariss, you were a great help on the ceramic capacitors, now I'm questioning the differences between film caps. Noticed the polypropylene is much lower...
Hi, I've three 201's, driving size 34 steppers at 72V 7A, the rated torque is 1280 oz/in, for some reason I cannot get above 360 rpm under Mach1 control...
Hugo, 2 points: 1) Mach1 tops out at 8 to 12kHz. 12kHz is 1,200 full-steps per sec or 6 revs per second. That is 360 RPM. You are being limited by the ...
Hi Mariss, Thanks for your reply, first I'd like to thank you for the schematics for the returned current, I have made it and works great. Mach1 could go up to...
Hi all, I got the Gecko put in the Ahha box working today. I only used the step and direction wires on the Ahha Z-axis to the Gecko. I screwed the Gecko to an...
Hello Coop, Thanks for the update. I was able to get my AH-HA going by swapping the bad X axis with the Z axis. The axis was still working but the movement was...

Will the processor in the gecko 2002 have enough capacity to do the geometry calculations for a hexpod? I'm imagining that the host computer would output xyz...
Elliot, Tests indicate that the G2002 can do circular interpolation on 3 axis- pairs simultaneously while using less than 50% of the Rabbit RCM-2300 resources...
Thanks, Mariss. If someone else wants to jump in, feel free. But if no one else has the time, I can locate the correct algorithms for hexapod/Stewart platform...

The Rabbit on the G2002 uses a language called "Dynamic C." This is a subset and superset of standard C. You also have the ability to embed assembly language...

Jerry, I have it running circles (well, actually 1 circle per enter key stroke on the PC via USB) on a very nice NEAT 4" x 4" table. Your choice of radius,...
