Getting MACH 3 to do a leadin with wiggle!!

Problems and questions
1

Hi to you all,

I have sheetcam combined with mach3 for a plasma solution.
I can set the leadin to “normal”, “ramp” ore “wiggle”.
The cutting path in sheetcam show some extra lines that could become a ramp ore a wiggle. In the NC however, (after posting) some moves are there, but on the wrong place AND without a Z command!!
Can somebody provide me a post where the ramp ore wiggle is working!!

A note: after searching this forum I learned the Onleadin() function!! This is NOT in my post. The post that I use is a standard post that comes with installing sheetcam. The name was something like “mach 3 with dthc”.
I also use the probing function to set the Z to 0!!

What do you have your pierce time set to? If it is short you won’t get a wiggle. The number of wiggles is calculated from the pierce time, feed rate and wiggle length. Could you tell me exactly what post you are using. Most of the Mach posts should output Z moves.

Hi Les, Sorry to but in, I to am interested in this, is it for thicker material ( I’m guessing )? I may have jobs coming up for 1/2" steel.
Thanks Ray

Yes. It is mainly for thicker materials where it takes an appreciable time to pierce. As the torch is moving the back spray of molten debris tends to exit sideways instead of blowing straight back onto the torch.

Thanks Les, Is there a on line manual or where would I find guide lines for setting up this feature ? Ray

I am afraind there isn’t much documentation on setting up wiggle pierce. The problem is that I don’t have access to a plasma cutter to run tests so I don’t really know what settings work well.
