General Mach Discussion / Re: Wiring FL60STH86-3008B 8 wired stepmotor HELP!!!

Hi guys
I use both these motors and at first sight they appear identical and are supposed to be interchangable. However there is one very annoying and subtle gotcha.
See my post http://www.machsupport.com/forum/index.php/topic,12773.msg83404.html#msg83404 (reply #5) to see what I mean. The scheme on the left is M60STH88 and on the right is FL60STH86. At first glance they look the same, indeed all the colours line up with the labels A, A dash etc. BUT the start of the coils is on different wires. Parallel wire an FL60STH86 up as per the M60STH88 and it'll be phase fighting and jumping around like a box of frogs. Use the diag on the right for the FL60STH86 motors.
Cheers
Ian
