General Mach Discussion / Re: True 4 Axis Simultaneous on Mach3

« on: November 24, 2012, 04:23:12 PM »

YOu normally do not move all axis in 4th axis protocal. The axis that has the rotary inline with it normally stays on the centerline of the axis and the rest of the axis do all the work as the tool needs to stay on the centerline. There can be exception to that rule but the CAM will have to able to calculate where the tool point actually is.

IF you do not understand what it is you are looking for PLEASE get qualified help to find the problem BEFORE something bad happens.

One of your pictures show what looks like limit wires having the shields going to the frame. Bad idea. Another picture show s the back of the controller and shields going to the supply earth AND you ALSO looped pairs together at the controll box  THERE was serious grnd loops.

The idae of star point grounding is that ALL sheilds lead to ONE terminal point at the EARTH GROUND.

In one post you talk of the motor frames and sheilds being CHARGED with voltage. That means you have crossed the DC common and grnds somewhere. and you have a current loop leaking voltage back to earth ground.

You really need to start over.   Earth Ground is NOT DC common and not AC neutral.  TH earth ground is a last chance safety to help keep you from frying yourself when something shorts and you are touching the machine .

Earth ground is also a place to drain any noise that accumalates in the wiring sheilds.  You never want to piggy back grounds to easch other or to DC comm or AC neutral.


I would start from the begining.  Surely you have the wiring schematic for the controller. Wire it as the drawing  THEN check for stray voltages. THERE should NOT be any anywhere. IF there are find out WHERE it is coming from. You could have a miss wired control box that is bleeding voltage out to chassis grnd inside the controller.  A GOOD RMS voltmeter is your friend.

The problem could also be the SUPPLY side of the machine someone COULD have mis wired a neutral to a grnd somewhere in that curcuit and YOU are getting the backfeed at the plug.

BUT rest assure you have a problem somwhere and it could get deadly at some point.

Trying to trouble shoot your electrical problem from thousands of miles away is like fishing with rocks.

I would start at the wall plug and start adding on componets  and work your way out untill the problem showed up,  then fix it.  Look for stray voltage from the chassis/case/frame back to earth ground. Seeing as you have already let some magic smoke OUT it could be from anywhere or from a damaged component inside the boxes.

Not unless you are running IR tubes(;-). If you think back you have been here many times before only to com back and say NOPE it still does it. You have serious wiring problems that you need to get to the buttom of.

The Manual should tell you everything you need to know. Give it a read.

I was looking at some of your pictures of your machine and reading some opf your voltage to frame comments and you have serious grounding problems .

IS this a customized screen set or the Standard 1024 screenset. ON what page are you refererring to for the tooldesc label.

Have your M6 macros changed ?

The nice part about only using 1 macro is that it can be programmed for Sheetcam. Values like switch offset can be applied directly to the macro. You have up to 3 vaules you can bring in.
