Mini CNC / Re: Mini mill kerf

1. I know of no tools that will help you with this. Perhaps someone else knows of something and will jump in here.

2. I can't recall off the top of my head, but if you google g-code for cnc machines, it will list the g-code words for that. They are pretty common (although I can't recall myself at the moment).

Is your concern the safety glasses or your fingers when adjusting focus?

I'm with @Zax, I don't fully understand what you are asking?

BCL requires the use of Grbl 1.1e for image engraving. The developers of this version of Grbl do not have any room in the firmware memory to support 'cutter compensation' (technically the wrong term to use for lasers). And there never will be that feature in Grbl/Nano CPU. There is simply no more room for extra code.

I took a look at what it would take to add Kerf compensation to BCL and it turns out to be an extremely large modification. So at this time, I have put it on the back burner.

I have bought several modules from Aliexpress using the vendor Novel Life. Bing has always been very helpful.

That's the problem. You're using the wrong Grbl. As stated in the trouble shooting section, BCL 2.0+ must be using Grbl 1.1e.

Do you have the Normal laser operation radio button selected? (see attachment).

What ver of Grbl firmware do you have loaded?

Yes, it should start to burn right away.

Can you please give me the steps you do in your test burn process? I want to see if you're missing a step somewhere.

Yes, that is very possible...I converted my 3D printer to a robust Z axis laser machine...using a 1.6 watt laser head, I was able to cut 3/8 thick wood. However, the success of that I consider to be a laboratory success wouldn't work in the real world because of the number of passes to cut 3/8 thick wood is not practical.

I wouldn't use 98 for anything...really...

We need more info about your laser machine.

What controller board?

What firmware are  you using?

Who did you buy your laser machine from?
