How to Run a Large Stepper On A Small Board without frying
Hi all,
I was thinking of buying some Gecko G201's for my first router, and buying brand new motors and making a small machine at first. I figured that way, I wouldn't have to move from a small system to a big system and by new drivers and steppers. But then I thought of just getting a cheap kit and gettting some good motors, ( again so if and maybe when I move up I don't have to buy twice). I was looking at the Hobby CNC 4 axis driver for about $60 for four axis. I want to buy some 190 oz-in vexta motors for this. They are rated at 3 amps and 3 volts. The board is rated at about 1.25 amps per phase continuous and 1.5 amps at startup ( just wondering, what's that mean?). So my problem is, how to run these motors at 1.25 amps or whatever. How much torque would I lose by running these motors on this driver? Would there be any other problems like overheating, or lost accuracy?
Thank you very much for your time.
I really appreciate it.:rainfro:

They should run fine, but you'll lose about 2/3 of your torque. You might want to look at the drivers here:

A little more money, but you may not need to get Geckos in the future. Or, you could buy 190 oz motors that only use 1 amp or so. I saw them on the Oriental Motor site.

Where do you get the parts for those boards?
Thanks.
Also, how much do you figure the cost of these would work out to, I mean the single axis ones for one.
Thanks.
Hello?
He's got parts lists with part numbers for Digi-Key. http://www.digikey.com

What's the cost work out to total after all of the parts are ordered?
Thanks.
You'll have to figure that out yourself. I have no idea.

Oh, just wondering from someone who else has had expierience with making these boards. I figured it out, and I'm not sure If I can say on this post.
Thanks.
