I have minimal documentation on the AXYZ stepper drives (AXI 2200 microstepper). I have a wiring diagram and some calibration data for the machine size, steps/mm, velocity and acceleration. However, I don’t have specs on the drive step timing (ie step time, step space, dir hold, dir setup) in nanoseconds.  

Is it safe to just try a few of the pre-configured Geko drives and see what happens? Overall, how big of
an issue is this and what are my options to figure it out?

 

 

Yes, G1 moves are controlled by the feed rate but G0 moves are at full machine speed
Also multi-axis G1 are coordinated but G0 moves are not.


You  could use some logic (say not + or components) or the lut5 component
in conjunction with your external spindle-at-speed signal to force  spindle-at-speed
true either when the spindle is on and the external spindle-at-speed is true or
the spindle is off.

A lut5 example might look like this:

setp lut5.0.function 0x0d
net spindle-on lut5.0.in-0
net ext_spindle-at-speed lut5.0.in-1
net spindle-at-speed lut5.0.out

A lut5 function value of 0x0d means it's output will be true either when in-0
(spindle-on) is false or if both in-0 (spindle-on) is true and in-1 (ext-spindle-at-speed)
are true.
