y+ will move the head towards

Your Y axis is flipped. +Y should go to the back. -Y to the front. This places 0,0 in the front left corner.

See this post on what you must set based on your physical printer and then what you need to change to make that work.

I think he is using the version 3 config.g and still on firmware version 2 , so I think it just ignores parts of the config file and works in a default way.

Yup you're totally right.

To update to RRF3 you need to upload these two zip files as is one at a time to the /sys folder using DWC.

i tried v3 but didnt have enough brain power at that time to change all the needed files for it to work.

0,0 is in the rear left corner

front right corner is x440,y535

Your config files are already using the format for RRF3, so you'll either need new files for RRF2 or update to RRF3.

See my linked post earlier about why you want 0,0 to be the front left corner. At the very least to understand how to get your prints unmirrored.

@Phaedrux
i understand that if i modify my physical layout, i can achieve the goal of the correct homing direction .and thus a non mirrored print

But my original question is Can it be changed in the software as so i dont have to change anything physically.

with every cnc i have built. i can easily tell it what dir to home and what axis. this plastic printer just boggles me . lol

Phaedrux

I'm not saying you have to change anything physical. It's all software settings. If you read the post I linked it tells you what had to be set based on your physical printer.

0,0 is just a coordinate. Putting it in the front left matches the slicer and cad software coordinate system.

The endstop position is irrelevant. It can be anywhere you want. The firmware just needs to know where it is based on 0,0 being in the front left.

Your homing moves are set in the homing files. The direction has to move towards the endstop.

The direction the motor actually goes is determined by the direction of rotation which is also defined in software.

tracar

its a bit much for me, i did upgrade to 3.11 but then it took me 3 days to figure out how to downgrade and get the wifi part to connect.. im more a hardware kinda guy. this software is a p-i-t-a for me.

so can you show me a visual example of what i need to change in the code ?

Phaedrux

Sure. Post your current config.g and the results of M115 so I know what firmware you're currently on.

Physical location of endstops is left and rear correct?

@tracar

Do a M122 again , so we can make sure you are on version 3.1 of the firmware.

Still version 2 firmware and running 3.1 config.g

@peter247

To update to RRF3 you need to upload these two zip files as is one at a time to the /sys folder using DWC.

https://github.com/Duet3D/RepRapFirmware/releases/download/3.0/Duet2and3Firmware-3.0.zip

https://github.com/Duet3D/RepRapFirmware/releases/download/3.1.1/Duet2and3Firmware-3.1.1.zip

DOWNLOAD , BUT DON'T UNZIP.
Go to the system tab and click update system file , find and select Det2and3Firmware-3.0.zip .
If it says your our running 3.0 with m122 repeat with the 3.1 file.

think im getting somewhere.

homing works and reports as
x0
y535
z5
z moves dow 5 after homing , all good here

after homing, when i jog X+ it goes away from the end-stop and moves to the right,

and when i give Y+ its travel is reversed, it should be moving towards the sensors , to the back of the machine, y- moves it towards the sensors and the back of the machine.
what needs to be changed to correct y motion travel?
