Motors not moving on delta printer with duet wifi

  • Hi

    Ive just assembled a delta printer and am in the latter stages of setup. Everything is connected and ive used the configuration tool to set the perameter's. However, try as i might, i cannot get the motors to move. i've been through the forum and tried all suggestions but to no avail. M122 spits out this:

    Please post your config.g.

    What firmware version are you using?

    How are you trying to move the motors?

  • Hi, thanks for the reply

    Heres the config.g file

    I bought the duet wifi over 18 month ago but only just got it out of the box. The firmware was v1.19. I tried to move the motors prior to updating to the latest last night, resulting with no change in the situation.

  • @dwmee

    How are you trying to move the motors?

    They won't move without being homed, unless you issue M564 H0.

  • Thanks for the reply

    Ive just tried your suggestion M564 H0. I get the response - Movement outside the bed is not permitted.

  • If i try any move, like G1 Y10 for example i get this response:
    G1 Y10 F6000
    Attempt to move the head of a Delta or SCARA printer before homing the towers

  • By the way, despite saying i updated the firmware, it still appears to be on:

    Firmware Electronics: Duet WiFi 1.0
    Firmware Version: 1.19.2 (2017-09-01)
    WiFi Server Version: 1.19.2
    Web Interface Version: 1.19.3

  • @dwmee

    you could try to temporarily home the axis
    G92 x0 y0

    Before you do so, move the head so the carriages are in the middle of the travel on the towers and the head is in the centre. I would suggest doing that with the power off.

    You also need to change your endstops from M574 x1 y1 z1 s0 to M574 x2 y2 z2 s0. This is because the endstops are at the top of the towers at the maximum travel.

    G92 x0 y0

    Thanks for the suggestions

    However, I still have no movement

  • administrators

    The correct way to test the motors on a delta printer is described on the delta printer configuration wiki page,

  • Hi dc42 & jay_s_uk

    Thank-you for your help and guidance. I have managed to update the firmware to the latest & all seems to work as it should. Continue to be helpful &awsome
