Using CC Version 8 and CM 640, without a bit setter, makes me save a separate C2D file for each tool used. Is there a way around this? CM will pause and let me change the tool if I have them all in one file, but I see no way to zero z. I am using a Shapeoko 3 XL machine.
No, this is the way things work without a BitSetter.
The only way to re-zero while CM is running a file is to use the BitSetter.
Perhaps other GCode senders would allow you to do something, but that’s a question for those experts.
C3D is still selling BitSetter and BitZero for SO3 and you really need these. The BitZero and BitSetter are the simplest and easy to use tools but make your CNC life much better.
Each one is $120.00 but worth their weight in gold. If you can only buy one the BitSetter would be first. You can set zeros manually.
In the before days of v6,7 or 8 you had to save each toolpath as a separate gcode file. Sounds pretty much like you are are currently doing. It was time consuming and you are prone to making mistakes managing so many files. C3D has come a long way since I got my SO3 XXL in 2019. I have BitZero, BitSetter, BitRunner and HDZ. Each one has improved the quality of my CNC life.
Thanks for the quick replies. Pretty much what I expected. I will order the bitsetter. It looks like a good add to my machine and I think having everything in one file is a great idea. BTW I have the bitZero V1, but don’t use it - I think it is too much trouble and doing the initial set manually is pretty easy.

I would agree that a BitZero is not as necessary as a BitSetter the way C3D has their software setup. However for me the BitZero is useful because I use the center of my projects often and also use bottom of material. So my V1 BitZero is used a lot. The paper method works well as long as you have a supply of paper available at the machine. I cut up pieces of paper into about 1" x 3" strips to have on hand if I want to use the paper method to zero Z.
Doesn’t have to be paper, just anything that is a known thickness and won’t damage the bit / endmill.
I use Aluminum spacers, with a wireless keyboard so I can jog away from the computer. Once I’m happy, I just enter the height of the spacer in the Z position. You can enter anything there, it doesn’t have to just be ‘Reset to zero’ !
There is another solution.
It’s called a Speed Setter by PWN CNC. You basically use a Collar on each bit; they come with a little tool you can use to ensure each collar is set to the perfect height.
IMHO, the bitsetter is well worth it. Same with the bit Zero. I suggest you get them while you can.
Thanks again for the responses. I have ordered the BitSetter.
I have installed the bitsetter and now really like having just one file for design and toolpaths.
