I've been looking at the camtronics setup but it's still a little expensive for me. Right now I'm looking at going with the 600 oz/in servos with encoders direct connect to lead screws (yeah seems like it's too much power but I'm of the Tim Taylor school, if I'm going to run into something might as well do it hard), going with the geckos probably the g320s (it's late not sure if thats correct) The only thing that I'm worrying about right now is the breakout board and the connection to the computer via parallel port. I've got some plans started tonight for the machine, try and post them sometime this week when they look a little cleaner. Trying to get a working area of 36" by 48" with a 8" Z axis. I'm going to go with 1" dia hardened rod with bronze bushings for cost on the linear slides. probably put some kind of lubrication system on them with scrapers to keep dust from getting in between the bronze and the rod. Does anyone know where to get the cat track cable guide suff for a reasonable price in the northwest?  |
