How to do a bit change in the middle of a project on a CNC machine (shapeoko xxl) 

I have the xxl and have also found that if you use a drill stop set from home depo you can set up your second,3rd, 4th bit on your first zeroing. When you zero the first bit put bit 2 in, drop router to zero then the bit to the paper like normal and tighten. Then zero the drill stop on the collet nut. Do this with every bit you have and At least that way when you're prompted for Tool change it's literally just the plug in the bit and send it (like the software makes it seem to be) and you can produce a quantity much faster more automated. Also a dab of Loctite and a flat spot goes a long way for the collar to not slide over time ensuring the drill stop is flush against the collet nut.

That is correct

If u set the XYZ with the touch probe with the end mill and run that code (circle), can you then use the touch probe to do the Z with you V bit for the “Subscribe!? Wouldn’t that be a perfect way to do it? I like you method, but it doesn’t work for me when accuracy has to be 100%. Thanks for sharing.

Errr figures lol. Ima have to check that out. Thanks for the heads up Iujon!

Thanks David!

Thanks brother!

@@ToolReviewZone You Are The Man :)

Haha right back at ya TJ!

Thanks Michael!!!

What does this do?

@@arbjful The m6 command will cause gSender to pause (make sure you have Pause selected in the gSender Tool Change Settings) the program so you can change to the next tool bit and zero it. Hit Resume and the program will carry on carving with the new tool fitted.

@@pw3111 is it possible to do the z offset routine for the new tool bit, during the pause?

@@arbjful yes it is. As long as you have “Pause” set up in the gSender “Tool-change” setting, it will pause when it reads an M6 command so you can change the tool and re zero it. An M0 command basically freezes the jogging controls but the M6 allows you to jog. Hence re zero the new bit.

Thanks Jeff!

Yeah I'm busting out some Steelers signs as we speak bro. Love this thing!

Still think your skills got me beat bro!

In UGS you could setup a macro to make it move to a predefined position.

Probably. It was 4mm

Yeah its really up to how you want to set it up. I like the shallow but faster passes

@@ToolReviewZone i think im gonna give that a try cuz i always feel like its cutting too much

You have to adjust your height limit on the program. If you don't set that, it won't raise high enough

Ratt n Roll! 🤟
