Craftware gCodes

edited January 2017 in Repetier-Server
playing around with Craftware I'm noticing some strange effects in the gcode parsing.
1. looks like the 1st layer print speed is WAY slow.  63 sec in vs 10min in rep server.
2. the 3d visual of the model looks awful and squished in many places
3. gcode is parsing is incomplete and stops ~50%

I have not tried to print of an SD card, so I'm curious if anyone else has seen these.  note that the same model and similar settings in S3D or Slic3r show no issues at all.  So I'm suspecting something in the craftware generated gcode isn't parsing properly.

I posted this on the craftware forum ;


  • per the suggestion on the craftware forum I changed the "startup extrude" from 15mm to 0mm which also removed the M83 from the gcode.  now, rep server is atleast calculating the info correctly, but the thumbnail doesn't generate and clicking the "eye" icon does nothing;
  • Just tested and saw the strange output:
    Start code should be
    G0 F100 E15 ; startup extrude
    and not
    GF100E15 ; startup extrude

    not sure what parser makes of this but it is straining your luck with autocorrecting incomplete gcodes:-)

    Then I see code like this:

    If you retract 7.5mm and the print there is no output (strange lines missing in perimeter). Extruder will not output anything there. Not sure why you have that, but that is a big error I think. And if you do not manager to come back to positive extrusion in absolute counting you have no visible layers or your filament has gone backwards out of extruder in reality. I think that is what is happening here.

    First layer time includes heatup first bed and then extruder and that adds 5-6 minutes to that layer time. Hope that explains everything. If you found out about negative extrusion preview should look much better. If not let me know, then there is more to it. Also you need to disable relative extrusion mode or everything is takes as relative:
    G0 F100 E15 ; startup extrude
    then first layer is much more correct and print with repetier-firmware would succeed.
    Hope these come from you.
  • I think I managed to fix the startup extrude which removes the M83 command and address the retracting 7.5mm you referance.  This print managed to print, not well, but it printed ok.   However, the 3d render doesn't render it.  the parsing is fine, just not the 3d image.

    here's the working gcode if you want to load it:!ApzOdVx9w7haifUpiHWMw3o9ybp9hw
  • Just rendered the image and looks perfect. What I wonder is that in printes around 200,200 so you seem to have a big printer. Have still your wnaho settings which limit x,y max to 200 so rendering removes everything outside.
  • Oh yes sorry. This gcode is for my big corexy which is 42x39x36 :O. Not the wanhao. I'll try to reupload it again later. As an aside I have a nearly full size 8hr print going at the moment. Sliced in craftware and printing through rep server. IMG rendered fine too, so it might just be this particular gcode. I'll keep trying others later.
