I bought a new bit and figured go head and give it a try. (1/8in flat ) Decided to cut out the Y plates. and my cut is well… lets say less than perfect.
Any idea whats causing this?
Can you explain more about what is wrong? Maybe post a pic?
Sorry about that didnt realize I forgot to post a picture.
All my settings are in mm, fusions simulates the cut just fine.

Can you post the gcode
Sure thing

Now even on a previous project I had completed. This is what’s happening
Could it be settings inside the repetier host settings ? I did change the size of my table to match mine. Hmmm. I bet. Give me a second.
Nope that wasnt it.
It looks like you are running the same 1/4" gcode with a 1/8" bit. You need to run it through cam again with the 1/8" diameter set on the tool.
That kinda makes sense, but that doesnt solve the problem of the part being double in size.
I had to reupload my post process again for some odd reason. So I am wondering if that has something to do with it.
Just so I knew I wasnt crazy, I made two small 25.4mm x 25.4 mm squares. I cut this rather quickly, and as you can see, these are well over an 1". Has anyone, anyone at all experienced this ?
Could a steps/mm type setting have been changed somewhere?
Are you referring to the software ? If so, I dont believe so. I have gone over my notes of the software changes and it looks like the same one I had before. However I’ll double check to be sure.
@jeffeb3 in your firmware, you have, on line 721, #define DEFAULT_AXIS_STEPS_PER_UNIT set at 80 80 4000 500. Can you confirm this is correct for the 2209’s?
Can you post the gcode for these squares?
The 2209 uses 1/16th microstepping. So with a 16T pulley, I think that should be 100. But that would make it too small, not too large.
Sure thing.

That’s not my firmware:
BTW, the firmware I am posting here isn’t really for anyone to follow. It is just my backup of my configuration, and it hasn’t really been tested beyond some drawings.
I’ll take a look at the gcode next.
Here is what I found in the firmware. I had to dig through my notes, but I did change the default axis steps to double @jeffeb3. Which before my boards went crazy, seemed to work just fine. No worries, I switched these steps back to the normal 100 100 400 100
I just tried to run the test cubes again, and I noticed the size difference when I brought the gcode into repetier. With that being said, I am fairly certain it is either the pp inside fusion (which isn’t likely because I have used the same one before) or I have some how messed the settings up inside fusion360. Which again, isn’t really likely, because all my files that I have already milled, are all coming out double the size inside repetier. With that being said, I might try to uninstall repetier and reinstall and see if that changes anything.
@jeffeb3 that is certainly your firmware from github. However, I did some digging and I was actually inside the A6 config file. I apologize I was looking in the incorrect place. The settings I am referring to is on line 721.
