Pay for config / json files for my corexy printer build.



  • @veti
    Hi so I’m regards to making alterations to instructions I can manually edit the particular line save and re-up through the web configuration ?



  • Thanks for the help everyone much appreciated I will try to keep the amount of questions to a minimum..,,,,,,,,,

    Don't be afraid to ask questions! I was also new to the duet firmware a couple of months ago, and I've found this community to be extremely supportive!

    To get you introduced a little bit, @Phaedrux, @deckingman, and @Veti are regulars who know what they're talking about and dc42 is the duet designer. All are very knowledgeable and very helpful.



  • if you edit the config.g file in the web interface it'll ask you save changes and if you want to reboot the board for the new settings to take effect.

    you can also just run any of the config lines in the g-code console to update the settings on the fly (there are some exceptions where the order of commands is important, but for the things you'll want to change, like speeds, directions, travel limits and limit switches it can be changed on the fly)



  • @bearer Thank you

    you can only upload the config.json file, not the config.g

    the idea of the configurator is to give you a basic working config for your printer that you then tweak to your needs.

    i.e work out the basic for your printer that you can input into the configurator.
    then do some tests prints and start tweaking features like pressure advance, stepper current, jerk and acceleration to find the optimal settings for your printer.



  • @stevo My approach is to always keep and maintain the configuration files on my PC. Then if I need to, I edit the PC based files and upload them to the Duet. That way, I always have a working backup should anything go amiss with the SD card.
    Any text editor can be used to edit the files - notepad++ is one that I use (it's free).



  • @deckingman
    OK thank you



  • @veti
    Thank you

    I think @Phaedrux must be short of caffeine

    More like toddler induced sleep deprivation.



  • Afternoon all,
    I have edited all the files as mentioned in the previous comments,
    When looking down on the printer with the two steppers controlling x and y at the bottom the tool head travels in both negative's axis direction to the bottom left.
    I have purchased a genuine V3 BL touch and would like to connect this to the Duet WIFI 2 next.
    After looking at other posts i have more doubts than when i first looked lol.

    So without doing something i will regret i don't need to physically break any connections on this version of sensor or add resistors.
    But i need to add a Gcode to set the correct voltage for the sensor ?

    Have you read the link deckingman has mentioned ? -> https://duet3d.dozuki.com/Wiki/ConfiguringRepRapFirmwareCoreXYPrinter

    Quote from the Movement Section: https://duet3d.dozuki.com/Wiki/ConfiguringRepRapFirmwareCoreXYPrinter#Section_Movement_section

    For a CoreXY or H-Bot machine, RepRapFirmware assumes that the motor connected to the X motor output moves the head in the +X and +Y directions when it runs forwards, and that the Y motor moves the head in +X and -Y directions when it runs forwards.

    Then test for the correct X motor movement by sending these commands from the console:

    G91
    G1 S2 X10 F3000

    If the head moves diagonally in the +X and +Y directions, all is well. If it moves in the -X and -Y directions, change the S parameter to S1 in the M569 P0 command. If it moves towards +X and -Y, or towards -X and +Y, turn the power off and swap the X and Y motor

    Read the whole section again and run each command to test if everything moves in the direction it should



  • it sound like you are still in cartesian mode rather than corexy mode.

    for bltouch see this guide
    https://betrue3d.dk/bltouch-on-duet-wifi-configuratio-and-usage/



  • I have followed Mark Rehorst's (thank you Mark) how to set up core xy origin and Endstops article origin is at Alpha motor all positive movement is in the direction of the top right pulley.
    The tool homes back to the Alpha motor.

  • @stevo Do you have a problem with the motion or not? - I'm a bit confused because it sounds like it's doing what it should do..

    To be clear, if you command an X positive move, the print head moves from left to right in your diagram and there is no movement in the Y direction. Yes or no? If no, what happens when you command an X only positive move?

    Conversely, if you command an X negative move, the head moves from right to left and there is no movement in the Y direction yes or no?

    And a Y positive move moves the head towards the back and there is no movement left or right. Yes?



  • @deckingman Yes it ticks all the boxes Veti mentioned in still appeared to be in cartesian mode guess its my poor description lol

    Thank you



  • please post your config.g so we can have a look at what you configured so far.



  • This is where I'm up to so far.
    Im in the process of adding the BLtouch wiring to the existing loom need to remove existing Z axis end stop.

  • just to double check you are running firmware version 2.03?
