All,
I have asked similar question in past but now I am down to actually purchasing and installing so I will ask with more detail this time.
I am building a CNC router that has a 4' x 4' operational area. It is a gantry type so there will be dual racks on one of the axis. Here are the questions:
1. What ration / pressure angle is best for the application?? Plan to do a gear redution drive on the steppers for increased resolution.
2. Where is the best place (most cost effective) to purchase the racks and pinions.
3. Any other ideas for driving this size of machine. It will also be a plasma so it will need to have jog rates at 1000ipm and drive a plasma at 800ipm.
Any advice / help is appreciated.
Thanks,
Kirk |
