Hi Guys,
Thanks for all the good information. I kinda expected the answer about the steppers being slow by nature. I'll have to wait until after Christmas to upgrade the power supply and drivers. I was looking at a full Geco or a setup from Keling, just to get good quality. Unless you have other suggestions.
In answer to the question about testing the motors off machine, yes I did and I wasn't very happy with those results either. I was hoping that under load they would perform better. I'm used to automotive engines where non loaded they over rev easily. I am surprised that a cordless has more torque than these steppers. Makes me rethink the entire stepper concept (has anyone dsimantled their cordless and wired it in? LOL). I'm posting the motor specs. for recommendations on the power supply, drivers and/or new steppers. I've tried compensating for resonance and got minor change. I'm using 1/8 micro-steps and the motors sound good until they lock up. Unless whislting and other weird noises while idle is unusual. Running they are smooth. They get warm, not hot, and are great for warming your hands while working in the cold garage!
I went with the Toshiba 5650 mainly for ease of installation. One board does all, but the board is limited to 36 volts. How do Geco or other quality systems get wired in? The multiple box setup has me confused.
Once again thank you for all the help,
Richard B.
