Been a LONG time since I was on this forum. As I get older, I am starting to disassemble my wood shop (so my kids do not have that task!!)

I have an alpha 2HP Spindle 96x48. Wonderful machine...

A user with an older PRT and a new computer is looking for help
to build and manufacture some parts.

I got him going a couple of years ago but his old computer system died. The Shopbot support...

There are actually 3 sets of controllers in your picture.

I would get a schematic from Shopbot before making the call to
the electrician.

I believe you have a defective contactor or defective...

These contactors have built in heaters which are essentially
fuses or bimetalic strips so when they get too hot (undersized or device
pulling too much power).

You need to select the...

do you know the make and model of the controller?
Does it have OVERLOAD RELAYS in them?

The overload relay is a bimetalic strip that acts like a resettable fuse.

When it gets too hot, then...

Hey Kip,

Tell me what you mean by "PULL". The contactor is engaging, hence the

I have to say that this contactor is very busy!

So I have a couple of thoughts...

SO if you work with people (nursing, health care, counselor) you get paid low wages but if you get a few computer skills under your belt, you can make a solid 6 figure salary.

I think cleaning the contacts did the trick.

Warnng: if you clean them too much, you will wear the copper or silver alting off the contact...

There can be only two problems...

1. That the control circuit (start, stop, coil and COntact #4) is wired incorrectly
2. That contact #4 (leftmost in the picture) is worn or corroded.

How do...

Hi Wayne,

Is the starter a self contained unit with the start and stop buttons separately?

The reason for this question is that if there is a start/stop station SEPARATE
from the starter, then...

Exactly what I needed!!

I demoed my system to a fellow that is interested in a system. he will be cutting primarily hardwoods but wanted to know if the system could cut 3/16 soft brass.

You talked about reducing the stepover.. A second thought is what wood are you using? Poplar and Boxwood are good for carving because of the lack of grain but they fuzz up a lot.. You may want to...

So my situation was that I was pouring a foundation for the shopbot room (18 x 24) and a adjoining foundation for the refurb in the house which was
24x50 to contain the shop. The challenge was that...

When I spoke to Frank, my understanding is that the relay may not have enoght power to drive (close) the contactor. I wanted to do the same thing and he said this is not how it worked.

I was in a class with a very wise man on this forum.
