I am new to CNC and this forum so please be gentle with me
I recently purchased a used Sherline 5400 that is 3 axis CNC
the books were lost in transit and all I can find out about this is that it is
a retrofit from Backtrack Manufacturing which is written on the driver board
I was told that this system is about 5-6 years old, looks older to me but then I am new.
The mill has the old style backlash nut locks. My question really has to do with the steppers, all that is on them is "57BYG" and "No.960710"
no voltage or amps, I think the driver maybe dead and would like to replace it
but with out the volts and or amps of the motors I don't know what to buy.
Does anyone know this system and could you supply me any info at all.
I would sure appreciate it! My budget is of course low and would hate to have to buy motors as well,
maybe later after I become more experienced it would pay but right now I just what to learn how to do this all
