Any time you design anything, you know there are iterative processes to all design as they improve.
I am moving away from Boroglass since it is expensive, this is not all bad. I was able to find a precision aluminum plate with a tolerance of .005" which is absolutely terrific for 3D printing. My print diameter will still be 400mm +/- a few mm.
As for pushing the envelope, instead of using a stationary tool holder, I plan on using a stepper driven tool holder that will rotate. Disengage the electromagnets on the effector and and the stepper will pull the tool head above and then the tool holder will rotate and switch the tool head and then return to the effector where the electromagnets will engage once again.
Short and sweet for now!
