Chip,
I originally used two chains over idler sprokets with lead weighted counterbalances, but before I got it completed I picked up a pair of gas struts (220 lb force ea), and am now adapting them to the knee. If that doesnt work, I can always go back to the counterbalance weights.
The only real problem I have is I have not been able to get an accurate weight of the knee assy, so Im guessing a lot. I have been given 600lbs, down to 450 lbs. Does anyone actually know please tell me if you do. Unfortunately I dont have air available, so thats out. Thanks. rogerbsstt
Another question. My machine is set up to only have a limit switch at the end of each axis, that is used for a limit and a home, I think. Can I use this setup to home the machine to these limit switches and then somehow enter a work area size in Mach 3 to specify the working limits of the machine? This would reduce the number of switches and pins needed.
Thanks rogerbsstt
