To try and answer some of your questions:
-- My total budget is $1300.
-- I do have stepper motors already but no drivers. I had motors left over from past projects. They are 680 oz-in holding torque, 2.80A, 90V
-- This machine will be for hobby/prototyping different ideas for new designs.
I completely agree with your advice, and thanks for those comments. I'm modeling up the design I plan to build in SketchUp, and I've been looking at components online for about a month. I hope to post the information on the build online, probably in a blog just because that's an easier format for me to organize the information.
Some questions I have:
Are there other components that I should consider for performance vs. the cost? From your initial comments it sounds like these may be OK, but I'm definitely not locked in. Also, you said the BK/BF blocks especially required some work--could you give me more information on what type of work I might be looking at?
Do you think that it's worth the extra $$'s to go for the larger diameter rails and ball screws? I'm sure that especially with the ball screws this is dependent on the motors and the speeds I hope to achieve, since increasing the diameter quickly increases the weight.
I'm also curious about the software and electronics that I should consider, so any tips there are also appreciated. So much to learn . . .
Thanks again,
Daniel
