I may be mistaken, but is that G17 part of the problem?

Ok did the commands all worked but the last G0 Y. so I did G0 Y0 and didn't move just said ok
The first command moved it up from zero on the bed to 1/2in up then next command mover it to the right 5ins the g0 y0 did nothing other than screen said ok

Ok G92 x0 y0 z0 g20 g0 z0.5 moved up 1/2in go x5 moved right 5in g0 y5 moved back 5in
should be center of board not quite but close, measured board its cutting is 10x10in doing all the commands places cutter center measures 5in left to center of bit 4 7/8 right to cent of bit 5 in front to cent of bit and 4 7/8 rear to center of bit. I am using Makercam cause it's easy to follow and I don't have to pop down 20 windows and choose a bit then lots of other inputs. I chose it cause the video I was following used it so I stuck with that.
But like I said I'm asking it to cut ONLY 1/16th of an inch down total and it ends up cutting much more. I think its just my inputs in the wrong places on Makercam seems it wants to cut 1/8th inch down every time total. I'm telling it TOTAL depth -0.0625 and STEP DOWN -0.03125 so total depth I'm looking to cut is 1/16th inch and stepdown 1/32th inch per pass as I understand it. The stepdown default is 0.05 ive been taking that as each cutting pass so I enter it as -0.03125 for taking off 1/32th of an inch at a time only. Or I think that is what its asking and my numbers are right.

It sounds like the machine itself is moving as expected so let's get a hard look at the g code.
What I need to help you is a screen shot of the settings you are using in MakerCAM. Then we need a copy of the g code output. Finally, describe how you zeroed it and what the outcome was. We need allof those prices together for the same project please.

Ok i home the machine first off, then i move the bit to left front of machine and set it flush on the left front corner and i ZERO x,y,z I then turn router on load Gcode and run it. THe first cut is over what I wanted like I placed 1/16 or -0.0625 under TARGET DEPTH and then under STEP DOWN 1/32 or -0.03125 now PLUNGE RATE is at 10 not sure really what that is but was 30 and all videos say down to 10 So im asking the TOTAL cut be only 1/16th inch and to cut each cut at 1/32th or maybe it figures how much to cut not sure. THe WOOD is Spoiler Board 1/2 in in cutting on and the BIT is 1/8th in . Here is the settings under Makercam in the photo and the peace of wood im cutting on is 10x10 1/2in thick and set that in Inkscape I drew a Square 10x10 placed my text inside of the 10x10 square so I know it wont cut outside my work board in cutting. The letters might be 7x7 inside the square. But my problem is I ONLY want to say go down into the wood 1/16th of an inch total and it seems it like to cut down 1/8th inch or so. It makes like 4 passes to get there and finish. IN the photo you can see my numbers im using so im thinking im reading Makercam and what it wants for numbers on each line. That last line PLUNGE RATE im not sure on it and the number.

I'm lookin at the Gcode in UGS. The total depth from bottom of cut to the top of the safe distance is .25 inches. So that would be 1/8 depth of cut (DOC) and 1/8" of safe distance. It is showing four passes of 1/32". Now, I ran it through another simulator with the same results and an estimated cut time of 1 hour 1 minute and a zero of left lower corner.
On a side note, the G-code you posted was for a different operation. I sign that says "Larry's Man Cave". However, the pictures and examples for settings are something entirely different with a different set of values. It's throwing me off. It's much easier to help if we have the relevant information for specific operations and not mixing files for one thing with descriptions of another. Even if they relate.

Like i said im being told change this change that try this try that. OK so using just one or the other whichever one my thing is that when i go to cut no matter which photo or gcode there both close one is set to total depth 1/8th inch another is set to 1/16 inch total depth and what its doing is none of them its taking first cut below what i want the total cut to be. That is why i posted and was asked to post what im placing in Makercam, TOTAL depth if one enters say i want not to cut down NO MORE than 1/16th of an inch id place under TOTAL DEPTH -0.0625 is what i understand and it seems it wants to cut near 1/8th of an inch first cut. This is where im lost at. Im going to go buy 12feet more of wood tomorrow and cut 10 more 10x10x1/2 squares and run more trials bothe sides of the wood so like past 2 days 20 cuts and ALL of them cuts way to deep . Im not mad at the performance of the Machine i love it but I want to cut metal SOON and no way will i be able to with it chomping down 1/8th in at a time on its first cut or pass. Im looking for a number in inches and where to enter it on Makercam that tells it ONLY cut down max 1/16th of an inch or only cut down 1/8th of total depth . Say i wanted to just skim across a peace of glass one hundredth of a thousandths this thing is going to drop 1/8th of an inch right off 1st cut . IM trying to understand is it the numers im placing or the not knowing makercam or is it jumping steps for crazy thing or another. Right now i dont care its cuting not center or taking 3hrs for a cut , im trying to figure why its going down more than what i enter into the program or am i entering it wrong or not in the right place. Why does it go over what I enter for total depth on first cut , i enter -0.0625 for 1/16th DEPTH total and 0.03125 1/32 inch STEP DOWN .
To me that says I want to ONLY cut a letter 1/16th of an inch deep total and try and cut ONLY 1/32th of an inch at a time to reach a total DEPTH of -0.0625 1/16th of an inch. The program says it will figure if it needs to take 1 or 50 passes to get to the depth one needs to or split the last cut if it only needs to cut less than 1/32nd of an inch. The speed or taking an hour or 2hrs was in the RATE i had at 30 not at 50 and takes 25 minutes. But still jams down 1/8th or so on first cut and i dont want but a total depth of the cut to be 1/16th of an inch. Sorry if i keep repeating myself but we seem to keep chasing the question around. So im asking under makercam what numbers and where should i enter then to get a POCKET letter 1/16th of an inch deep only. Not 1/8th or not first cut more than 1/16th of an inch and 4 cuts more after for total of 1/8th of an inch but just a POCKET letter down 1/16th of an inch and dont care if it takes 3hrs but depth i want near perfect.
Like i said i will be going to cutting metal parts as soon as i figure this out but right now it will snap a bit , rip the machine apart and destroy gods knows what they way im using it or trying to enter the info. I know the bed is high left rear 30ths forget that even if i try and level the spoiler board right now with a cutter it will chop the hell out of it if i say lets cut only 1/16th of an inch at a time till level, it will chew into it like with the letters im tring to cut down. So this is why im asking what am i doing wrong that it wants to chop or cut down deeper than my input data .
Sorry not mad just trying to understand this and right now only solved what FEEDRATE is and does and that solved the long cuts.

If you do some searching you'll find that Inkscape and Meshcam can sometimes not play nice together. You'll also find that there are many many people with problems using the two for CNC stuff. So even if we get this one figured to not be a CAD/CAM issue, I highly recommend going another route even though it sets you back by learning a new software. I think in the long run you'll be happier getting away from them. If you want something easy and straight forward, use Easel. Search the forum. There's a thread on getting it set up for your machine. If you try to let easel set your machine up it will jack with all kinds of stuff.

Sorry not mad just trying to understand this and right now only solved what FEEDRATE is and does and that solved the long cuts. As I said, viewing the G-Code you posted in multiple views shows the numbers are good. It's cutting 1/8" deep total in 1/32" step downs. It's not the numbers you're inputting. There's something else going awry here. Just out of curiosity, have you checked to make sure the the cutter is tight in the chuck? Have you watched the Z axis to see if it's "falling" as opposed to a controlled plunge?

The bit is tight and its smooth flowing, it runs over to the spot then it dors plunge kinda scary im not used to seeing things cut that fast or move around that fast but then ive never used a router . Tomorrow i will try and do one with a total depth of say 1/32 and plunge rate and total step down of the same 1/32 so should only need to do one pass very fast and then ill mic it see what it looks like. I got so pissed and feed-up yesterday and today with doing 40 cuts and all of them not being right. The looks after is fine but thing is going to deep is not a good thing if im going to try and cut alum parts out and im removing 1/16th from an 1/8th in thick peace of alum and it cut through it first pass jejejeje So ill jig something up tomorrow and try a few 1/32 depth cuts and see what happens. I know left rear it will be deeper with it being 30ths higher but the center is really closer to zero. Thanks for the help i know the programs not yours or anything its just nice to have someone willing to try and help someone out . I run a 3d printing room and im answering things all the time trying to get people going and its not even my machine I just bought it and they dont really offer any type of real help on it lol The builder is even in the room to follow what people are asking and wanting. So to find someone to help is hard now days and I thank you for all the help its not easy not being in front of the machine to see what its doing . Well ill let you know tomorrow what happens. Thanks...

Sure thing. And again, I would strongly suggest you try the exact same setup but using Easel to see what happens.
Also, take a quick video of the machine so we can see how it plunge and cuts.

Here is a view of my first cut and i think you can see its not cutting down only a total of 1/16th of an inch but the cut turns out ok just lot's deeper than i told it to. And i think you can see it's ok on the plunge speed and moment. youtu.be/yuwDH6jMrbACNC Cut

Ok. Give me a few. I'm going to send you some Gcode I want you to run. If it cuts as intended, we know it's CAD/cam and not machine related.
