Interested to see your version and to see how reliably it produces equal length rods.

I'd think that excessive resin would disappear in the hollow carbon rod, which is the path of lowest resistance. Maybe it'd help to glue only one side at a time and hang them up, so the resin runs down the rod.
I was surprised about your printed rod -jig, since it must have taken some time and lots of filament.
BTW what did you mean with, you "have the right bearings to measure the length with calipers"?

When Haydn measures these he puts 3/8th inch high-grade ball bearings on each end and measures with calipers, as the end surface of the ball cups is potentially rough and isn't a mating surface, so measuring from those surfaces doesn't really tell you the effective length of each arm.

I had good results with flexible couplers between leadscrew and stepper shaft. But I added a steel ball ( 4.5mm ) between them. Now the DOF in Z-direction is eliminated and it can only flex in X&Y.

Are you saying that by adding a ball bearing inside the coupler (with no gaps to either end), it would eliminate lateral stretch and compression? Compression would be eliminated but I'm not seeing how it would stop the stretching.

M305 P1 X501 R4700 ; heater 1 uses a PT1000 connected to thermistor channel 1 which has a 4.7K series resistor
