Hey,
The website says it's for unipolar motors only. It appears that your 6 wire motors should work, just depends on how they are wired I guess.
It appears that this driver board you have is not a microstep drive, nor will it allow high motor supply voltages. I speak from experience here. I've got an old Supertech 4 axis stepper cnc system, setup for 12V. It is pathetic. I'm affraid you will not be pleased with the performance of your system, as I wasn't pleased with mine.
The nature of steppers is to loose steps when the load is higher than the torque of the motor. Your 53oz in motors are going to have a hard time driving anything of any weight without loosing steps. For steppers to remain accurate, the motor needs to have more torque available than it will ever need on it's application. Finally, bipolar motors of the same size have much more torque than a unipolar. I'm not familiar with your machine, but I would be looking at bipolar 200oz in + at a minimum. If you need more than one person to move your whole machine, then 300 oz in + would be recommended.
Furthermore, you are going to need a better driver to get any decent performance out of any motor. At a minimum, check out Xylotex bipolar micro step drives or better yet get some Geckodrives. I always hear about people using 20 - 25X the rated voltage on the motor for the DC supply. With Geckos, the right sized power supply for your app, and decent software (Mach2) you will have those motors flying smooth as silk at 60+ IPM, rather than a jerky, rough, unreliable 10 IPM that you might get from your existing setup.
I ditched steppers all the way, and I'm currently building a Gecko DC servo based system for an Emco Turn 120 cnc lathe (big in the educational field as well). Do some research, Geckos and Xylotex have GREAT support for thier products as well as tons of users that can help you. You are going to be on your own with your existing stuff. Good luck.  |
