I finally got my DRO,s in agreemjent but when I move to a ne location to set 0,0 for a job the Zero key does not work.  What setting do I need to change to allow me to reset the work 0,0 to the new location?

General Mach Discussion / Jog mode problem

« on: December 23, 2014, 05:47:43 AM »

I seem to have encountered a problem with the jog mode setup in Mach.  when I start Mach3 the default is to step not continuous jog.  This started when I purchased a pendant "remote control" I am not able to get Mach to default to continuous jog.  Is there a way to do this?

The plate works connected to the controller as normally open when the tool touches it reacts but the macro makes it go nuts.  I never know where the tool will end up.  it will rise but sometimes an inch and sometimes 1/2 inch etc.

General Mach Discussion / Tool Zeroing

« on: November 28, 2011, 10:16:24 AM »

I have looked at several posts for tool zero macros etc. tried several but with no success.  I obviously do not unerstand how htis works.  One I was really interested in was a simple copper plate of a known thicknedd two leads one to the controller and the other to the tool with a cli[ when the tool touched the copper it would auto register a prefixed dimension of the copper plate.  I tried many ways to make this work I needf help this would save me a lot of time if I can get it to work.

I can do that.  The movement I saw was grab the router standing in front of the machine and I could move it along the y axis in and out about 1/32 then from side to side along the X axis same thing. I have tightened the bearings a bit removing that slop now I can check for backlash knowing what I am looking for.

I think I have found at least part of the problem I cut with the wizard a 3" dia meter hole it was about .005 undersize.  then I looked at my x and z axis found I could move them slightly with my hand so I think when the router pulled on the bit it lagged behind the motor then when it pushed it still lagged behind the motor creating some of this undercutting.  I am trying no wot get them adjusted so they are snug but not tight.  These bearings are a bear to adjust.  it's a bolt through an eccentric and a hex nut so you have to sort of coordinate the tightening of them so you can achieve a good fit.  The wizard helped a lot took any variable of software etc out of the equation//

How can you check backlash on the machine?  I have never doe this before.

I am planning on that tonight.  It might even be the vertical and horizontal tracks with the v rollers sloppy enough for a small movement.  4" above the work surface it would not take much of a movement to move 7 thou and drag behind the gantry.....I will be looking at that tonight too.  First make the cut with the wizard see what I get then move from there.

it is a router motor mounted to a plate guided by V slides and bearings V that ride on the track.  Same for the X axis.  I am only cutting wood and usually only 1/8 per pass conservative on the material removal to allow the cutter to clear the flutes.  I also only run around 50 IPS not fast.
