hbot homes correctly but prints mirrored ,



  • so from looking from the front of the printer, my x/y endstops are in the rear left corner,
    this is the only place i want them to be due to wiring ease.
    now im not the best on programming, but over the past month have been able to get , for the most part, everything to work sorta. thru trial and error, so i may have repeated a few lines here and there....... Z axis works as it should

    Board: Duet WiFi 1.02 or later
    Firmware: RepRapFirmware for Duet 2 WiFi/Ethernet 2.05.1 (2020-02-09b1)
    Duet WiFi Server Version: 1.23
    CoreXY

    after homing to the left rear corner......., x+ and y+ will move the head towards and to the right of the printer (right front corner)

    i also can not figgure out how to get the second z axis to be separate from the first. to use as bed leveling.

    i have an expansion board so i can use a closed loop setup,

    prints are mirrored, they look good but all are mirrored from the stl.

    So basically i like the way it is set up with the homing in the back left corner, but need to get it to print non mirrored, can this be done ?

    The printer is a bit messy. but its still in the design steps, once i have the thing printing right , it will be taken apart completely and rebuilt all squared nicely, with a few new parts added.

    feel free to make any changes to the code, so i can see how this related to motion.

  • @tracar

    This my guess what happening :-

    You have set high end homing ( right ) in your config.g , But your machine uses low end homing .
    Your homing files say G1 H2 X300 , which is correct for high end homing , but you have the motor direction wrong too.
    So it goes left think it's going right and hit the end stop on the left thinking it's the right end stop.

    Two wrong making a right .. and so you have mirror !!!



  • @peter247
    so which lines do i change to to reverse the direction it homes ?



  • @tracar

    So does your machine home to the left or right , front or back.
    I think I may be wrong what is the first few line of M122

    M92 X200.00 Y200.00 Z800.00 E138.2316760023409 ; set steps per mm

    are you sure your extruder shouldn't be E138.2316760023408 step per mm , never seen anyone set the Esteps to 13 digits before.



  • @peter247

    i posted some photos of the setup. it homes to the left side, and to the back.

    as for the 13 digits, lol.... old habit just a cut and paste, cant be too accurate hahahaha

    where is the M122 located



  • @tracar

    where is the M122 located ? top of the screen !!!
    Type M122 in the send code box and click send and post the first few line in the console .

    what are the 4 control boxes at the back ?



  • @peter247
    the 4 black boxes are closed loop drivers for the 4 steppers x,y,z1,z2
    i will get back to you on the above when i get home



  • @tracar

    This time I think I'm correct , because after looking at your config.g and homing file I could not find a fault.

    Your machine looks a bit of a beast !!!
    I tried to making my own version of the cr10 and over killed it to the point where it just printed so bad , In the end just got a ender 5 plus.

    closed loop drivers ? , do you just connect the wire which was going to the steppers are use external drivers ?.



  • @peter247
    closed loop drivers are the ones for steppers with encoders built in.
    the steppers wont skip and loose track of their position even if you push an axis out of position. it will self correct....., its all good but if the belt skips then it will loose position. really good for systems with ball sxrews.


  • Moderator

    @tracar said in hbot homes correctly but prints mirrored ,:

    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.

  • @Phaedrux

    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.

    0,0 is in the rear left corner

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

    0,0 is in the rear left corner

    front right corner is x440,y535

    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


  • Moderator

    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 ?


  • Moderator

    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.
