Constant stopping



  • I started having an issue recently quite out of the blue, not after any updates or anything where any file I started printing just keeps stopping. Basically it performs a few lines of gcode then stops - e.g the initial wipe maneuver takes place and then the printer stops and pauses for 30 seconds or so and then performs another few lines and pauses again. Any ideas what's going on? Here are the board specs:
    Board: Duet 2 WiFi (2WiFi)
    Firmware: RepRapFirmware for Duet 2 WiFi/Ethernet 3.1.1 (2020-05-19b2)

  • M350 E256 X256 Y256 Z256 I0 ; configure microstepping without interpolation

    this is overloading your cpu.

    change to x16 with interpolation

    dont forget to change the steps/mm



  • Thanks, I'll do that, set a print going and get back to you



  • on a side node your themistors are incorrect

    M308 S0 P"bedtemp" Y"thermistor" T100000 B4138 ; configure sensor 0 as thermistor on pin bedted
    M308 S1 P"e0temp" Y"thermistor" T100000 B4138 ; configure sensor 1 as thermistor on pin e0temp

    B4138 is the default and incorrect for your thermistors.

    try the values from
    https://duet3d.dozuki.com/Guide/Ender+3+Pro+and+Duet+Maestro+Guide+Part+2:+Configuration/38

    creatlity uses the same on most of their printers.



  • Having changed the motor and thermistor settings, run an auto-tune I started a print again. Unfortunately, the same thing keeps happening

    Here is the updated config for convenience

  • can you post the m122 after this happens?
    the first was just after a restart

    @rickypilnik said in Constant stopping:

    M566 X900.00 Y900.00 Z12.00 E120.00 ; set maximum instantaneous speed changes (mm/min)

    Do you have mesh compensation active during a print? Low Z jerk values can cause stuttering X Y movement.

    you forgot to adjust the z steps



  • Adjusted steps, checked compensation is on and the pauses are still happening. Its not so much a jerk as a complete stop, wait for a bit and then continue. Here is an m122 during a stop

    I suggest raising the Z jerk to M566 Z60 and trying again.

    The low jerk values means that as the Z height changes with the heightmap the XY axis has to slow down to give time for the Z axis to move since it has to obey the lowest value.

    Reducing the first layer speed can also help.
