Slic3r 1.3.1 SDCARD prints perfect, Repetier Extruder problem

rcprcp
in Questions & Answers

I am using Slic3r 1.3.1-dev and if I slice and save the GCode to SDcard it prints perfectly, if I slice with the same settings via Repetier the Extruder almost stops on the first layer infill.

Even if I load the Gcode directly into Repetier the problem persists. I thought the extruder had stopped, but it is moving a minuscule amount, almost like Repetier is adjusting the steps, any Ideas where the problem could be ?

    Is the g-code in relative coordinates? Host will always start assuming absolute coordinates, so with relative coordinates you need to activate them in the start g-code for the slicer or use absolute coordinates.

    I believe all the G-Code is correct, printing direct from Slic3r also works perfectly as does sending the G-Code to Octoprint.   The problem seems to be only occur once the infill starts and might be related to acceleration or Repetier truncating something.

    I can share the complete G-Code, stl,  Slic3r settings  if it would be of any use ?

    You are at least right that you set printer to relative e coordinates and use them, so from that point it is correct.

    Host might truncate extrusion to 4 digit precision. But you need an extruder with > 10000 steps per mm to make that an error, so I doubt this is the problem.

    I see you have also many small negative moves. That might be part of the problem. In 2.1.2 I just fixed some problems with graphic display of such a situation, but we always send the original values, so doubt that.

    A gcode and the layer where it fails would be great so I can test what host does to the code or if there are some new kinks that makes problems. I see you seem to have at least non standard extruder handling. Wipe or something so that might cause a problem on our side.

    Okay I pretty much found that any gcode produced by slic3r 1.31-dev fails when sent through Repetier so I think I could just post my print profile. Basically what happens is the extruder does the rim and perimeters okay then as soon as the first layer infill starts something goes wrong and it stops extruding.

  • RepetierRepetier
    We printed fine with current slic3r and also no one else is complaining. So can you please post a download link for a gcode with the problem and the line numbers where the problem starts. Then we can analyse it much better.
  • rcprcp
    Okay, I uploaded a short video so you can see the difference between printing via Octoprint and Repetier. (BTW Slic3r-1.3.1-dev with Adaptive set @ 75%) Video is https://youtu.be/0b9sekUJCCw
    You can get the stl and gcode from http://www.tuxsoft.co.za/debug.stl  and http://www.tuxsoft.co.za/debug.gcode

    I mistakenly used the older version of Slic3r when I exported the profile, the only difference is that I enable adaptive slicing on 1.3.1-dev, I really hope this helps I have been using Repetier and Slic3r for over 4 years on Linux and Mac this is the first time I have a problem I am unable to solve.

  • RepetierRepetier
    Interesting gcode as it gives completely wrong extrusion length in server. Reason might be the same as your print problem. The gcode has one wrong line

    M221 S100{else}95{endif}

    This is flow multiplier and is a bit random what which software will interpret for this invalid gcode. Setting multiplier to 0% will be no extrusion at all. Preview looks good for me, but I already fixed a problem with local coordinates here for next release.

    Do you print using repetier-server over Repetier-Host or directly connected to repetier-host? I ask because server is a getting this complete wrong distance measurement so there might also be an error source. Will no winvestigate why server does this.
  • rcprcp
    Thanks for that info, on this printer I normally use repetier-host or sd print, this is the first time I have ever used an app-pak version.
  • rcprcp
    Thanks for your effort, I changed the cutom Gcode to M221 S95 and it now works as expected. Great support !
