Chester Conquest mill power feed

<< < (2/9) > >>

Darren:
I did consider pic, but it was way too far into new territory for me.

Now that would make an interesting write up to follow...... :thumbup:

raynerd:
Nice going John, I`ll keep watching with interest as this is the same milling machine I own.

I have reading  few thread on here about mill power feeds, I think Darren also has a thread. Why do you guys use standard electrical windscreen motors rather than hooking up a stepper motor? Electronics isn`t my strong point - but I just thought you`d have more control with a stepper?

John Rudd:
2 reasons for going with the wiper motor....it was £6...

I'm a tight wad...tight Northern git whatever..

and pwm speed control is easy to do...

Steppers can be expensive and need a stepper control circuit...slightly more complicated...

raynerd:
OK - I understand. So basically a stepper would do the same job just at a greater expense.

 Good luck with the rest of the mod, I`ll be watching!!

Chris

Darren:
John, what do you mean by 0%?

zero voltage or full voltage output?

Or should I say fully chopped or full intact wave?
