At Tiko 3D our vision is to make 3D printing accessible to all. We have created the most affordable, elegant and easy to use 3D Printer!

Your original weight was 85 g (nut) and that seemed to work for you. But now you need 3x that weight? Did I read that right?

They are spring loading horizontally between the two arms from each motor, close to the effector end and at the motor end, in order to reduce backlash. This is not my wheelhouse, though. What do you think?

Then when I release the head, everything moves down under the weight until all the slack of the gears is caught-up, meaning that ideal weight is pulling down and no more backlash in the gears. So now there is no delays when reversing direction in any of the motors. This along Teflon tape around the motor carriage clips and lithium grease on the guide tracks makes this printer as good as it can get.
Total weight added to each motors: 82 ~ 85 grams.
These picture are self explanatory. I use a hot melt glue gun, epoxy would do too.
