Hi ...I've got an application where I'm using a system that is designed to motorize a microscope, controlling 3 axis - X & Y Stage drive, and a verticle Z axis drive. When applied to a regular microscope, this works great. In my project, I'm trying to salvage a really nice microscope that, unfortunately, has had a reduction gear break...rendering focusing impossible (Microscope is no longer made/supported & gear is too costly to try and recreate).
I was able to get the Z axis mechanics under compression spring balance, where it now is resting at mid-travel, and can turn the focus knob with my hand...but when I try to hook up the motor, it is not powerful enough to drive the stage up/down very far before free-wheeling/slipping. I need a way to boost the signals coming from the controller board such that I can drive a stronger motor.
The driver board did have switches to set motor current, and I have them set to max, which is 1A. I'd like to still be able to use this controller (as it is a really nice package, combining extra functions I need)...so wondering if there might be a way to double the current (like from a stand-alone circuit) - similar to a voltage changer...or similar...keeping the stepping control, but developing stronger current. Would like to hear your thoughts!
