strange holes
« on: August 09, 2006, 12:20:33 AM »
I am not sure if thisĀ  is the right forum. If it is not I apologize. I am testing out a program for carving. I output the gcode to mach 3 and then test it there. I am getting these weird holes from the z axis and it doesn't happen when the z axis is a set depth, this happens when it move up and down.
Anyone know why this happens?

Looks very odd.

Post the G-code so we can have a look at the z moves.

It seems to happen around line n110 - n140.

I am not sure. I could have all of the settings in mach 3 messed up.  This was suggested in another forum.

"You might want to check your Mach 3 settings. If your setings for your Z axis is not correct then you can possibly get
more movement then the VCP toolpath actually tells it to."

I am not sure how to check my setting for the z axis. I am completely new to this so excuse my ignorance.
Thanks

Are all the holes at the Z plunge in point of all the different cut sections?

In the picture on your first post,  are the 'stange holes' where the cutter starts cuttting that section?

Yes and I think I have figured it out. I had the some settings wrong for my z axis too many steps so it was going deeper than it was supposed to but only on z.
Thanks
