Hello!!

[Butter1leg]

Hello All! Pretty new to the CNC world, and only been welding for a few years. I'm a retired veteran doing this for my retirement job!

Hi Butter1leg! Welcome aboard! Tell us more about yourself - what kind if table and software are you using, what kinds of projects to you expect to work on, etc.
Thanks,
David

Actually have a few questions as well, I'm sure someone can answer.
I'm using the Crossfire Pro, w/ razorweld45, Fusion 360 and Fire Control. So far I've made some signs, a couple of flags and a couple of customized fire pits. hopefully get my old employer and maybe some other local bike shops and other businesses to make any parts for them. I'm interested in the scribing, but I'll pick that up some other time.
My biggest issues right now is with the program itself I guess. I just started a couple of months go, is there a way in fusion or even in fire control to set a return to zero? It would be nice to have it get out of the way until the post flow stops and I can start inspecting and getting pieces off without having to manually move everything.
Thanks!

This web page show the operation on the Langmuir Fire Control and abut 3/4 of the way down is the answer for your question. Go to XY zero.
Don't know if you use SheetCam for the G-code generation but if so and Langmuir has a Post Processor that can be in the G-code to return to X & Y zero at the end of the G-code.

Yeah I know that button, just doesn't lift the z axis up. As far as in the code, I don't know if it's in Fusion, or if maybe there is a way to add line of code. and langmuirs post, I would have to contact them. I haven't tried SheetCam yet, I'm an above knee amputee, so I'm always trying to save a step or two!!
Thanks for your help

I looked in SheetCam and did not see a langmuir post processor listed. If you do start using SheetCam the move for X & Y to zero is attached here.
it also has provisions to lift the Z at the end of cuts, so it is not needed as the last line of G-code. If your G-code is generated by Fusion I'm sure a member here will explain what to do, or a Langmuir user will.
Have fun there are many great projects here or like you said a local business will use your service, just bring in an example of what you can do. A good start is do a logo or simple sign (small wall hanger) for them to see what is possible.

Business card holders are also a good way to demonstrate your service.

Something I thought of and that is the button is most likely a Macro that can be changed to add the Z movement. Now realize that the Z 0.0 is most likely to surface of the metal. If it is a macro and you can add a Z movement command I would tell it to move up to 1.0" before the X and Y zero command, like the line above.

Thanks for the help guys!!
