Post your configuration files (all of them) using the </>.
You select the tag from the toolbar and it creates a place holder piece of text "undefined".
Copy and paste each file over the text "undefined".
You likely have a M208 setting wrong.

Thanks for your help I'm new to the scene. im not sure what you meant by </> but I attached my files as best I could.</>tpre0.g tpost0.g tfree0.g stop.g sleep.g resume.g pause.g homez.g homey.g homex.g homeall.g Duet2CombinedFirmware.bin config.json config.g bed.g

@fcwilt I Meant 305 for the x y and 457 is the true z setting according to the original build volume. I believe it will be more like 350 after I finish mounting the heated bed

OK when you click on the </> in the toolbar you get this:
undefinedThen you copy and paste your code, replacing the "undefined" bit.
Then you get this:
; some of my code ; some more of my code ; gosh I have a lot of codeSo here is your config.g file pasted over the "undefined" bit:

Now as to the M208 setting of steps-per-mm.
The goal is to have the correct value that gives you the correct amount of motion.
So starting with your 400 steps-per-mm for Z:
- first issue a G90 command
- then issue a G1 Z10 command
- make some kind of mark on the frame even with the tip of the nozzle so you can measure from this position
- now issue a G1 Z110 command
- make some kind of mark on the frame even with the tip of the nozzle so you can measure to this position
- now measure from the first mark to the second mark.
If you measured 100 mm then the steps-per-mm is just right.
If it was greater than 100 mm then the steps-per-mm is too large.
if it was less than 100 mm then the steps-per-mm is too small.Let's say you measure 50 mm (just to keep things simple). That tells us that the steps-per-mm is too small.
Multiply the current steps-per-mm setting by 100/50 (what-it-should-be / what-it-measured).
Enter this value into the M92 command and re-boot.
Now repeat the process above until you find just the right value for steps-per-mm to move exactly 100 mm.

@fcwilt
I had to leave the lab that the printer is in but I will check this out in the morningaccording to my code the M208 command is the axis limits and M92 is the steps per mm
-
@reellife
Is that correct or am I just reading somthing wrong?
My understanding is if I entered that into the M208 it would change axis limits not the steps per mm -

I'm sorry - I was in a hurry - my wife called that dinner was ready - you are correct - it is M92.

@fcwilt
Thank you very much! It ended up being just over 2600 so I was way off.
I appreciate your time! -
Regards 2400 - that likely means your lead screw pitch is 8mm per rev, your stepper motor is 1.8 degree and your gear ratio is 1:6.
Glad to have been of help.
