General Mach Discussion / spindle and charge pump

« on: April 10, 2008, 01:19:15 PM »

I am wiring my Spindle through the charge pump and having no luck getting the spindle to start ? Here is the way I have it wired.

Charge Pump has 5 pin blocks on the end and 2 pin blocks on the side.

GND, 12v, N/C, Input, N/O Output
on the side IN 12.5khz, GND,

GND and 12v goes to Charge Pump Power Supply.

N/C has nothing, Input goes to Pin 14, N/O Output goes to -4 side of the Solid State Relay , +3 side of the spindle relay goes to Pin 15.

2 blocks on the side = IN 12.5khz goes to Pin 1, GND goes to LPT GND.

The charge pump is a CNC4PC, Spindle Relay is a Teledyne Solid State Relay 10 amp 120 240 volt,  3-32vdc.
The power supply is  Nemic LamBDA, Model HR-11, 24volt, 5.0amp.

Pin 15 has +5v Red X, Pin 14 +2.48v Green check, Pin 1 +5v Red X
Spindle still doesn't turn on, need HELP on this one. Would it be easies to wire spindle around the charge pump ? 

Thanks Wil Trower

My thinking is it might be best to replace with the same kind of board since I know very little about this procedure. Any help out there. Thanks Wil

Mach3 and G-Rex / motors running table not need help

« on: December 28, 2007, 11:03:36 PM »

I am new to this cnc world, and have loaded the mach 3 today and was going pretty good until , the tuning of the motors came along! I was tuning them as it said by the sound of the motor smoothness, with out chatter but I noticed the table wasn't moving in any direction. Can someone tell me what i need to do to make the table move with the motor or do i have an other problem. The mill is a Terco mill. Only one motor has any info on it and it runs at 200 steps per rev, other two have no tags on them, they are orange if that helps any. Not sure what else to say about it, let know if you need moreinfo and I'll trry to get it. Thanks for any Help...Wil
