What is the current state of your 2 motor stepper control library-- seems an issue with the latest commit?

I am interested in using the phidgets 1067 boards to control two stepping motors for RA and DEC control. I have used phidgets quite a bit for varios projects including the 1061 servo motor controller and prefer to work in python just because I am more familiar. Unfortunately, I only have 180 tooth worm drive in an old Meade LX3 to work with for my experiment. However, I have disassembled and the condition of the drive and worm is excellent and was well machined at the time.

I was thinking of swapping the 1/8 rpm motor with a Stepper and giving it a try to see what kind of results I might get For deep sky tracking, this drive would need to advance 1 tooth every 480 seconds with 2.5 steps per second without microstepping (based on 1.8 degree step angle?) Obviously, I am a complete newb to this but very attracted to the idea of stepper control. The 1067 micro stepping of 16 (while coarse by professional standards) would give me 40 steps per second theoretical? which would seem to limit vibration. Can you recommend a specific NEMA motor and a barebones strategy for a newbie approaching this task (assuming to start...DEC LOCK, one 1067 phidges controller and a raspberry pi 3 or windows machine available?? Thank you for any information.
