Hey Bob,
   Can you post the Gcode that gives you the huge circles? Also, you might want to look in general config, IJ mode, almost center of the page, try changing that and see if it helps.

Hi, Bob

Sounds like your using LazyCam, If so click on the lead- in marker.

Then Double-Click it, A window will pop up, At the top set the lead-in to a smaller Value.

Hope this it It, Chip

No I am Using Dolphin Partmaster sorry for typing error, Hear is the code just a simple square drawn in dolphin with a lead in/out the lead in is wrong and the corners of the square are deffo wrong. But like I daid if I change the post process to mincromill (which works on a taig mill) everything is fine????

Good to hear Bob,
     A post processor basically generates code the way a certain machine likes to see it. You may be able to make your own postprocessor by coping one and editing it to your liking or some cam packages actually have post generators, kinda hold your hand and walk you through it deal.  For some reason, I had to seperate my G0 rapid moves on mine at some point. I had to but the z on a seprate line from the x and y. I think it is because my knee is soooooo slow and I also had to change the way it generates code for arcs. Dolphin might write you a post processor for use with Mach or they may have one allready, what ever the case, let us know so we can post it. We have a place just for post processor for Mach. Their might be one there that you could use now. Here is the link.

Hope this helps,

Hi Brett,
Just spoke to dolphin and they have a post process for incremental, absolute, and 4th axis. so going to try and get hold of these. I tried looking at the post process file as another thing Dolphin does is put G00 and G28 on the same line and mach reports it does not allow this. I was a bit bemused by the content and drew the conclusion it was abit beond  my knowledge AT THIS TIME.  Bob.
