COREXY dual X-Carriage

edited November 12 in Repetier-Firmware
I have built a COREXY 3d printer with 2 x-carriage. Unfortunately I only get one carriage in motion. Is it possible to control 2 x-carriage with a COREXY design with repetier???

Comments

  • I never heard about such a design, so it is not implemented I think. How does that work with 2 independent X axis?

    Apart from not knowing what it needs I think with the dual X implementation in V2 firmware it should be easy to solve. Depends a bit on the math required to implement, but there should only be one tiny function required to change. To be exactly the only function you need to change is

    void PrinterType::transform(float pos[NUM_AXES], int32_t motor[NUM_AXES]) {
    FOR_ALL_AXES(i) {
    motor[i] = lroundf(pos[i] * Motion1::resolution[i]);
    }
    }

    which maps position to motor position in steps. Add there your motion logic and you are done.

    Requires a due based board at the moment.

    Thank you very much for the quick answer.


    The big advantage of this design in my opinion would be the low moving mass in Y-direction because the motors of the X-carriages are fixed to the frame.


    I tried to get the design to work with Marlin but Marlin says when compiling the COREXY with Dual X-Carriages doesn't work.


    I am currently using Repetier as my firmware. I could set the motion control in the firmware for the 1st X-Carriage to work perfectly. But when I tell the firmware that I want to use dual-X I can't get it to work :-(

    I use a Rumba Board with two stepper-driver extensions. The two stepper driver extensions are used for the mirrored z-axis stepper.

    For understanding I have attached a drawing of the belt layout.

    Is Repetier V2 already usable?

  • So you use the B part just twice to have to x axis I guess?
    Would at least be no big deal to change the motor equation for that and use it with the regular dual x code and your little mod.

    V2 is already usable if your printer uses only supported hardware components. All normal features are working and especially dual x was even improved last week by me. I run a dual x with it as only firmware.

    What is missing is avr support so rumba board fails under unsupported hardware at the moment. Adding avr support is planned as one of the next big additions to it since still many use the slow but cheap 8 bit processors. Not that 32 bit costs so much more.
  • With #define DUAL_X_AXIS 0 the printer works perfectly with one X-Carriage (X1 motor).

    I have now in the configuration.h
    #define NUM_EXTRUDER 2
    #define DUAL_X_AXIS 1
    is set.

    Unfortunately the X1 motor is no longer driven when testing the movements, only the X2 motor instead :'(

    I copied the configuration.h and the FAST_COREXYZ part of the motion.cpp below.

    motion.cpp:
    #ifdef FAST_COREXYZ
    uint8_t transformCartesianStepsToDeltaSteps(int32_t cartesianPosSteps[], int32_t corePosSteps[]) {
    #if DRIVE_SYSTEM == XY_GANTRY
        //1 = z axis + xy H-gantry (x_motor = x+y, y_motor = x-y)
        corePosSteps[A_TOWER] = cartesianPosSteps[X_AXIS] - cartesianPosSteps[Y_AXIS];
        corePosSteps[B_TOWER] = cartesianPosSteps[Y_AXIS];
        corePosSteps[C_TOWER] = cartesianPosSteps[Z_AXIS];

    These are the settings that work perfectly for only one X-Carriage (X1 motor).

    In the first two requests I tried to upload some pictures. Unfortunately this doesn't work? You know what I'm doing wrong?

    Again, thank you so much for your support.
  • That can not work in V1. You need to drive 4 motors with 3 coordinates, so you need an independent 4th motor that does not exist in V1. That is why I said to do it in V2 where we support up to 7 independent motors. There dual x uses A axis as second x axis motor so you can define a coordinate mapping to that motor as well.
  • Oh, that's so sad. I have already rebuilt everything :-(

    OK, what kind of board should I get if I want to use the V2 optimally? Would the SKR V1.3 / 32bit board be the right choice?

    Is it safe that my belt layout will work with a compatible board in combination with the V2 firmware?

    Can V2 BLT and TMC2130 work with stallguard?

  • No SKR V1.3 is not due compatible. We are working on more processors, but for now I'd go with a RADDS + Due to be safe. Hope to have RUMBA32 working beginning of next year. Already bought one. Would be easier to use with TMC2130 which are already supported in V2.

    What is BLT?
    Stallguard in principle works, but in your special case where 3 motors stall in parallel I can not say what happens. For use as endstops that might not be best idea. Pure cartesian printers will surely give better signals here.

    Of course you still need to teak the source code in the function I showed you before.

    I'd suggest Ultratronics PRO. It supports 7 motors, has 32bit CPU and lots of other cool features. Not sure though if CoreXY support for it has been implemented in V2.

    ...Talking about CoreXY - during the last 3 years I went full circle - from Cartesian to CoreXY with 2 belts then to CoreXY with single belt, then back to Cartesian. While everyone gets excited about simplicity of CoreXY kinematics (including myself in the past), the biggest issue they have is the length of the belts. With small printers that may not be a problem, but when you go bigger, and IDEX usually has bigger than average print size, then you may start experiencing print quality degradation. I don't want to discourage you, but this is something you may want to consider in your future projects.  

    Thanks



  • Ultratronics works with V2 and is overall a good board. The only thing I miss is an eeprom. So you need to use sd card to store what otherwise would be stored to sd eeprom.
