Well....... Duh. Yes Sir, that's what I need! excuse my novice ignorance. I'm guilty of reading thru the tutorials much too fast. I will try my best to comprehend that whole Mesh process. Might need help to fully grasp the challenge. I've never tried to 'edit' the Gcode before, for fear of ruining it. Give me some time to experiment. Should I post my config.g for scrutiny?

After running a bed-leveling macro, is it possible to 'record' multiple values of Z-probing made across the bed surface? Then implement those values to create offsets for Z, that results in a near perfectly flat surface. While my talents lie mostly with electronic design and playing guitar, I'm a fish out of water when it comes to programming.

Having great success using LightBurn to create a path for fly-cutting a thin layer off the sacrificial table.

@droftarts Well, that's a lot of information for me to digest! Lol. Might I see an example of code where M669 has been implemented?

M669 T1 S1

Thanks for the suggestion, but I'm not very keen on how to implement what you're talking about.

@Valveman I'm expecting a new cutter today. Plan to post my results asap.

If some reason, I choose to cancel a Job that is running, cancel only takes affect after the current motion has completed. Is that normal, as I'm new to all of this? Is an update to DWC or the 6XD a solution?

nested for X/ for Y loops

You got me thinking. So I just made an additional 'layer' to my projects' file, and labeled it bed-leveling. I then exported that G-code file to my SD card, and viola, it works! first time ever making anything move from scratch. Thanks so much for your assistance.

I'm not much of a programmer. Electronics and music are my forte. Completed the rebuild of my bench-top cnc router, and need a simple X-Y program that I can run a fly-cutter up and down the bed, in order to level it out. I use LightBurn to draw my projects, then use it to send G-code to the DWC, which then controls my 6XD mainboard. Everything is working really well, but the removable wood base needs to be leveled with a cutter, before attempting any engraving.

@Valveman My thinking is that the tilted layout, is the result of the Fusion-generated code done by my son. I'm going to have him send me an older version, prior to it being tilted, and see what happens. By the way, how can I post the code for you all to examine?

@Valveman M556 any significance?

@droftarts So, I just looked at a couple of the 'Jobs' that run at the tilted angle, but I don't see a line with 68 or 69. Am I too look somewhere other than the 'Job' itself?

@droftarts
That's me, Lord of the idiots.
My constant fear of screwing things up, makes me oblivious to what's right in front of me.
Rather embarrassing to be the dumbest newbie to the club.
But may I say in my own defense, that if you would show me a 40's-70's vacuum tube diagram, I would be happy to explain the whole circuit.Lol. Guess I was born about 30yrs too late.
Thanks, again.

The existing G-code file for engraving a panel was written in Fusion. It works, but runs at a 60° angle from the starting point, so as to fit inside the dimensions of my smaller cnc router. I've since then made it larger, and would like to run the code in the normal 90° perpendicular fashion. Is there a way to accomplish that without having my son redo it within Fusion?

Sorry about the duplicate entry. Appreciate everyone's advice. Actually, I've been the past year awaiting the release of MillMage. I was using LightBurn to layout my panel designs, as it was by trial and error that I stumbled on to it, and found it to be very organized and easy for me to learn. I then give those files to my son, who uses Fusion to recreate my drawings into code for the Duet.
Just heard from my son that I should look at Easel. My understanding is, the free version is simpler than Fusion, yet adequate for my engraving aluminum panels with text.
Will give it a whirl this weekend.
It's hell getting old.LOL

I've completely overhauled/updated my hobby cnc router. Heretofore, I always had my son process my original drawings with Fusion, then send it to the Duet/DWC. But I need an alternative, as I just can't handle the complexity of Fusion. LightBurn [easy to understand] hasn't released their MillMage ware as of yet. So I'm still trying find something for me to get my projects done. Any ideas?

All fixed!
I cannot explain when or how, but config.g was gone. It took my [digital] son all of five minutes to find [that] to be the whole problem. Backups took care of it.
I just wish I had video of exactly how I caused it.
I must slow down and be much more careful. Now I can continue with my spindle.

I'm using one of those pictured.

Wow, what a quick and concise response to my situation. Many thanks for the guidance. But before I go any further, I want to do a re-work to the spindle motor power supply.
Simply put, it's nothing more than a 120vac rectified DC voltage regulator, using a single FET transistor that regulates the voltage from 0-100v. And while it works perfect for this light-duty cnc-router, it does not offer any electrical isolation from its input to output. The PWM to DC converter board that was chosen to couple the 6XD to that supply, offers no galvanic isolation either. In as much as things have been working fine for a very long time, I can't help but be concerned about the possibility of ground current being looped through the 6XD, via its 15vdc [isolated] supply, and that hot-line-side spindle supply. With the common wires disconnected, I measure some 27v between them. While all it takes is two fingers touching them to cancel out the meter reading, it's about the only issue I find, that might have caused the problem in the first place.
Replacing the PWM-DC unit with an opto-isolated version, the ground loop circuit will be broken. Then I will proceed with the business of trying to salvage my precious 6XD. Thanks for listening.
