George,

Your clip did not make in your post. Have a 6061 aluminum project for a friend I am about ready to start so interested your first experience.

Does a great job!

What were the feeds and speeds?

Thanks!

George, don't see it. Currently out of the country and viewing on a tablet (might be the problem). I will check it out when I get home. Thanks for follow up

It is impressive how fast it cuts the 6061 but as a machinist, I think you would get a much nicer finish if you set the cutter another ½” up into the collet, and halved the feed rate.

I would agree. About 30secs. later the bit broke. Next time I will run the feed rate at 50 instead of 100 for a 1/8 bit. This was the settings Terry.

Pass Depth: .0313
Feed Rate: 100
Step Over: .05
Spindle Speed: 21000

Thanks for the info, I just got a few pieces of 1/4" aluminum scrap (3' x 4') and have been waiting for an opportunity to do something with it.

This post is from 2013. The video is probably long gone

Hi gang

I'm looking for info/experience for anyone cutting aluminum with the Stinger 3. Mostly will be cutting 6061 and 2024 sheet aluminum. But eventually would like to do some light "milling" as it looks like that is more than possible. ........ CAMaster says so anyway.

But for the time being, getting proficient with the VCarve software and WIN CNC is problem enuff. I have used Corel Draw for years and prefer to draw in that but the VCarve doesn't like the .dxf files exported from Corel. Example................ a circle isn't really a circle when imported. It's a lot of short straight lines that form a distance appear round. This carries on into anything that's not a straight line. I can edit it out but takes a lot of time and the accuracy can suffer. I am used to Corel where I can easily work within .001 inch and place objects precisely.

I have experience on another brand of machine with proprietary software specifically made for cutting sheet aluminum for aircraft instrument panels. But it is small and parts are size limited................. did a great job tho.

Even after getting the .dxf file created, I'm am having a hard time getting settings correct to make a cut or getting .dxf into a functional .tap file. I'm trying to get a handle on it before cutting with the price of the sheet being anywhere from $80 to $200 a sheet.

Thanx in advance!
