My drill wont drill!
« on: May 29, 2011, 05:19:44 PM »
Hey guys, I'm having a problem with drilling operations. The drill will go to the proper x,y locations but it wont plunge, it just stays in the clearance plane and goes from location to location. I have included the g-code its a simple small bracket that has four holes set to drill .1" deep the material is .09" thick.

The code is generated from visual mill 6.0 and my machine is a Sherline 5400 inch. It will mill without any problems, for some reason the drill operations don’t want to plunge.

Get rid of the L0.0
The manual said L=0 is not allowed.

Try it like this:

Ok I have a new question regarding drill operations. If I need to drill a deep hole, having the drill cycle to break the chip would be useful. What format does Mach3 Recognize so that it will retract a little to break chips? I want to be able to edit the visual mill post processor (Mach3-Sherline) so that the "break chip" option will post the proper G-code that Mach3 will recognize.

Any help would be greatly appreciated.
Mike

G73 Peck drilling in increments to break chips

G81 Straight drilling

G83 Deep Hole Peck drilling, Drill retracts out of the hole each peck to clear chips

IT is ALL in the manual (;-) , TP

Yes visual mill will create peck operations but the format is a  little different. I will need to modify the post processor to output the correct G-code.

Here is a photo of a bracket I designed using ViaCad2d/3d , posted using Visual Mill 6.0, and then cut on a sherline 5400 milling machine with the CNC upgrade. The holes were my problem at first until I removed L command.

I thought I would share what I was working on:
