AXYZ retrofit - Stepper driver settings

Category: CNC Machines

Start with generic values, should be 5000/5000, direction is not important so leave it at 20000.
You can safely try Gecko settings, mark the motor pulley/shaft with a marker and set it to go back and forth several turns and several times, see if it returns exactly where you marked it, if it misses even by a very small bit, do not use those settings on a production machine.

Just wondering if the existing tang primer 20K plugin will work for the tang primer 20k Lite board? It is a simpler board than the dev board and has 117 available IO. It's not a great deal more expensive than the nano9k.

AXYZ retrofit - Stepper driver settings

Category: CNC Machines

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?
