I have a project that requires driving a 14.5 inch telescope for photometry.
I lack the experience to make a stepper controller myself
I have the programmer and some parts to try and make a pic stepper controller myself.


However, do you have a pic controlled kit
I do not have a parallel port for a printer on my laptop

or do you have a suggestion as to what stepper driver kit you have that I can operate from usb from my computer.

I will want two axis

A little research came up with no hard timing numbers for the Linisteper so I did a little experimenting to see what would happen. I took Step Time and Step Space down to 25ns without any problems. Direction hold and Setup isn't as critical so I took them to 50ns each to verify function. For some additional safety margin, I'm using 30, 30, 100, 100 for the 4 Linistepper values in EMC2 with 18th step mode. Faster numbers may be possible but with my Latency of 12,001 and small motors, these are about the limits of my hardware so I didn't bother with anything lower.
