Hello, I need to transmit motion at a 90° angle, I was considering worm gears or bevelled gears, but then I thought about a flexible drive shaft, it would be cheaper and wouldn't have any backslash issues. I need to transmit motion at a 90° angle with a low toque and low RPM, the application is a simple and precise multiple rails positioning system for a few lasers. Do you think I could use a flexible drive shaft for my application? Would it be harder to turn, compared to a geared solution? Would I have any disadvantages?
