steps per mm formula and dual z

I haven’t tried it what I want to do yet. I’ve got a Azteeg X5 GT that I am setting up for my Trinus printer. the trinus has leadscrews on all axis. 2 Z, 1 Y, and 1 X.

based on information extracted from the firmware on the printer. the X, Y, and Z axis are using 228.5714 steps per mm. with 200 steps per revolution and 16 microsteps, that leads the thread pitch to be 14 mm per revolution.

my first question is, can I enter a formula into the alpha, beta and gamma steps per mm line in the config file? (200*16)/14 or does it want a solid number? looks like it is 12 decimal points long.

I am starting with 16 microstepping to make sure it works, then I will switch to a higher microstepping. I can go up to 128 but I fear that may generate too much heat.

228.571428571429 = ( 200 * 16 ) / 14
457.142857142857 = ( 200 * 32 ) / 14

my second question is, due to the 2 z stepper motors, would it be better to wire both motors into 1 driver, or to figure out how to use the E1 driver to run the second motor? for the second method, how do I configure this to work?
