Homing fails in all axys



  • Good afternon. After powering down my machine, from wich I just had printed 2 calibrations cubes on it, when I powered it up, if fails to home in all axys, wich is stopping me from printing.

    My config.g files is at it goes.

    I've reinstaled everything, with no sucess. I've tried to downgrade to 2.05, also with no sucess.

    I've checked my cabling in order to confirm that there was no loose wires.

    The videos ot this behaviour are the following:

    I'd really appreciate all the help I can get! Thanks a lot!!!





  • It never reachs the endstops, and when I force the home process, it slams against the endstops.



  • @rodolfo_paulo said in Homing fails in all axys:

    Z2560

    Thats an unusual Number for steps/mm, what setup is that?

    M305 P0 T100000 B4138 R4700 ; set thermistor + ADC parameters for heater 0
    M305 P1 T100000 B4138 R4700 ; set thermistor + ADC parameters for heater 1

    you have not set up your thermistors yet. B4138 is the default and not correct for your printer.
    loop up the specs for your thermistor.



  • @rodolfo_paulo
    whats the output?



  • @Veti It is a Hypercube Evolution 2020



  • @rodolfo_paulo You may not moving far enough for the initial movement in the homing files.



  • @rodolfo_paulo said in Homing fails in all axys:

    It is a Hypercube Evolution 2020

    i mean what leadscrew are you using to get that Z2560.



  • @Veti Endstops - X: at min stop, Y: at min stop, Z: at min stop, Z probe: not stopped



  • now press and hold one endstop and post the output again.



  • @Veti M119
    Endstops - X: not stopped, Y: not stopped, Z: at min stop, Z probe: not stopped

    But I do not have a Z probe... Should this be appearing?



  • @rodolfo_paulo said in Homing fails in all axys:

    M574 X1 Y1 Z1 S1 ; set active high endstops

    change this line to
    M574 X1 Y1 Z1 S0 ; set active low endstops



  • @Veti , you are a life saver! It worked just fine!!!

    Regarding the leadscrew, I've must have chaged that when I compiled a new instalation in the RRF Config Tool. I'm using an 8mm, step 4 lead screw...

    Is this correct?



  • 8mm 4 start leadscrew with a 1.8 degree motor would be 400



  • @Veti , if you ever stop by Portugal, I'll buy you a crate of beer or wine, which one you prefer!

    Thanks a lot! Now it's calibration time...

    But I still don't understand why did it all go bezerk, with the normal shutdown...



  • i started out with a 2020 hypercube as well, but have converted it to a blv cube since then.



  • @Veti What are the main differences, besides the mgn rail?



  • @rodolfo_paulo
    the parts are sturdier.

    and now all metal parts have been released.

  • @Veti Thanks once again!!!

    I just checked the prices at AliExpress.

    For the kit with the better parts it's more than $900. Then you get to pay more than $500 shipping.

    I'm not used to seeing prices like that out of China.

    it was not designed in china. the stores just offer kits.
    the project site has a bom that you source yourself.
    the kit you are looking at has original hiwin rails



  • @Veti said in Homing fails in all axys:

    Yes that much was clear. Still, I've purchased a few kits from China but none as pricey as that.

    Given I have four kits awaiting assembly I don't think the wife would understand why I needed yet another. 😉

  • @fcwilt
    the lite kit is a lot cheaper. it comes without the fancy stuff like led, panels etc.

    "Lite Kit" - where would I find that?

    Thanks.

    but i would check if you can source the extrusion locally.
    because thats what makes it expensive to ship
