x and y axis work fine. the spindle does not work. the person I bought it from ripped the end off of the connector and had been toying with it by just twisting the wires together. I bought some molex and wired it up....nothing....cut the ends back off and twisted the wires together.....nothing...

any ideas?
 
Randy,

I owned a 4 blade cutting station CNC by Leonard. It only had X and Y. The W was a constant speed for all 4 spindles.

Got any pics?
 
spindle is 200 s200

A command? I can't get it to work manually through mach at all...

On top of the fact it was run with the wires simply twisted together, I found all the heat sinks for the chips laying about the case, one on top of the fan. I suppose they could have shorted the thing.

Everything else seems to work fine...

If you don't see M03 or M04 in the commands, then it's not coming on.

Tom, M03 or M04 turns the spindle on.

Joey, on this machine in the 1990's you turned 1 switch on that got the one 220 Motor spinning all 4 saw blades. Another switch turned all the dead centers spinning. The rest was just X and Y.

On a side note after buying shims from Graingers we spent two weeks trying to shim so all four worked equal we were only able to get the upper two dead nuts so the bottom two were used for rough cuts.

We built a small room around it with sliding glass doors in the front.

If I remember right all my CNC's back then worked off (?) AhaHa control boxes.

This one has a Xylotex controller on Mach2 though.
Technically that is the A axis. The spindle would be the saw .
If the keyboard shortcuts are set on Mach 2.
XY on the arrows.
Spindle has no shortcuts afaik. You have to turn it on on the command.
The A axis might have a shortcut on the keyboard .

My cnc was caveman style. THe spindle speed was a Hightower spinner.
The router came on via M03 command. M07 for the vacuum.
Xylotex and Mach2 as well.

PS
I'd get rid of the Xylotex and get Gecko.

you might try borrowing one of the motors that you know to be wired correctly and connecting it to that particular drive and then just try to jog it...and vice versa with an obvious working drive.

It appears to be a 4 axis controller...is there 4 steppers? x, y, a? maybe the long axis is slaved.

The rotary stepper is a molex and the others are different connectors...

I could swap the wires on the card....

Been fiddling with it for two days getting the distances adjusted. I hadn't tested the rotary until today.....

According to the previous owner, it all worked properly.
 
lol, yah worked so good he thought he'd cut the wires in half and twist them together. It appears as if all 4 drives are wired....whats the 4th one go to?

I don't know how the original plug was ruined. After repairing the wire and attaching plugs, it didn't work so I tried it directly(which is how he did when it worked most recently).

I don't know what the fourth wire set does. There is a label on it that says "do not connect". I could have asked Blud about it, but I already felt bad about calling him at 7pm for advice.

What benefit would I see from the Gecko and extra cash over this(that is SUPPOSE TO WORK FINE...)?
 
What is your CNC experience? I think thats important to the advice you might receive.

I'm a cnc beginner I'd say. I did have that same model blud machine and sold it about 5 years ago. I got it set up and running, but then sold it... I also have a Taig CNC mill that has the same controller and steppers, but haven't used it in years...

Anyway, in reading everything I could find on setting up and building cnc controllers years ago, including most of the Mach manual, there are huge warnings that come with the controllers and stepper motors. They say if you connect or disconnect a stepper when it is powered up, you will ruin it. Seeing that you have a ripped wire, that could have very well have happened.

Those steppers are pretty cheap. You can get a new one and a new connector, and test the obvious.

If you are a beginner, you really need to read the entire Mach chapters on setting up your steppers. Print out the whole book and put it in a binder.

Good luck, from a cnc novice:)
