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.

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?

peter247

@tracar

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

WiFi/Ethernet FIRMWARE_VERSION: 2.05.1

Still version 2 firmware and running 3.1 config.g

peter247

@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?

peter247

@tracar

X homing to the left and Zero ... correct !!
Y homing to the back and 535mm ... correct !!!
Z 5mm correct if it is 5mm off the glass , you may need the set the offset

The Y should be a positive number not minus.

peter247

@peter247

getting closer !!!!

tracar

the homing works as it should,
the only issue now is when i manually move it in the x and y coordinates , the x works as it should.. but the y is reversed

moving x+ moves it to the right and away from the endstop

moving y+ does not move and y- moves it away from the endstop towards the front of the printer.

y machine movement needs to be reversed.

peter247

@tracar

You need to change Y homing to a positive and change the direction of the motor .. You must do both !!!!!!

You are back to my first post what's wrong .
end stops are correct.

tracar

change y homing in the homeall or the homey

@tracar

BOTH , Remove ALL the minus sign for Y

eg G1 H1 Y-540 F1800 to just G1 H1 Y540 F1800

I missed a bit , Change all the positive Y to a minus

G1 Y5 F800 to G1 Y-5 F800

So really invert anything use the Y axis , ONLY THE Ys NOT THE X or Zs

tracar

changes made. yaxis moves away from the endstops now when homed, all else works as it should

this is a coreXY hbot setup.

i can change the direction of the steppers if needed by a switch on the driver, as they are external.
