I am not new new as I have been watching the site for a bit.  When i check my box and found this message i did not think much of it.  Then I read the replies and I was shocked!  This is incedible.  I have obsessed about building cnc router and plasma cutters for decades.  Anyway I have done just that.  So my next exercise is to figure out what it is I want to build with the machines and build my business.  I live on a relatively small island off the west coast of British Columbia, Canada.  Here are a few links to what is happening in my shop.

All the best - Ron

artcam pro 2008 jerky motion issue

I am having some trouble getting smooth motion out of my router.  I am under the impression, i can not recall why, that cv does not work with arc moves.  I actually have two systems.  A plasma system where I had to change the posts in sheet cam from mach with arcs to mach with out arcs.  Seemed to be necessary to get smooth motion out of plasma table.  The router on the other hand is still aproblem.  The posts in Artcam does not offfer a post with out arcs.  I should metion I have limited exposure to gcodes.  I just know the problem is associated with the I and j codes.  ANyone had any insite to this work be greatly appreciated

Hi - Don't delete me
My name is Ron.  I have been automating industrial equipment, processes and plants for25 years.  Mostly PLC and Plant Wide Supervisory and Data Acquisition Systems but i have always been intrigued with CNC.  I am winding down in business and and have now successfully built a router, a plasma cutter and upgraded an engraver.  I have currently working on a 4 by 8 router and plasma cutter.
