Is there a reason that i couldn’t just measure the length of my top beam and then use a caliper to measure from the end of the beam to each motor and then just subtract that amount from the total length of the beam to get the spacing between motors value?
My motors go about 1/2 inch into the space between the joists in my ceiling, so the chain stretch method wont work - there’s no straight line between the tops of the motor cogs.
Measuring the length between the motors is tricky with a tape measure and it’s also not very accurate, but measuring the full beam and then subtracting the edges seems like it should work.
Also - am I supposed to measure from the center of the cog, or the inside / outside of it?
I’m assuming from center of gear like this:
