  1. Thanks for all the replies! My first problem was that Cura was exporting this instead of GCode: ;CURA_PROFILE_STRING:eNrtWk1v20YQvRJGf8QeEzRWSUqKnQi8JLV9aYoAdtHEF2JFrsStSS6xu7QsG/rvfbtcUpQst05jNF/SwQaHM7szb958GFZOl0zGGePzTEf+IPAWNM9jnfHkqmRKQXTsSaYlTTQXZcxKOs1ZdCFr5imR8zTO7QF9g5fejOOMlJWK62UU+l4pbm9zFit+y/B+5FWSlzpWFWNpNPbdo2ZF... etc I thought this was some kind of unreadable, compressed GCode - it turns out it didn't like the model I was using. The instructions for calculating the E value were very helpful and my ultimaker is spitting out the models I want with my own custom version of spiralize. My last (for now) question is about these lines: ;LAYER:0 ;TYPE:WALL-OUTER Is the layer number significant? I also wonder if the ;TYPE is changing settings on the UM2 - maybe the SKIRT setting increases the E or Z value perhaps? thanks!
  2. My new Ultimaker 2 is running well with provided models but I am attempting to run some custom GCode. The code in question is meant to run continuously and essentially draw a spiral (and ultimately a taller, thin walled cylinder). I have this working well on the Makerbot, my settings are dialed in - but when I run similar code on the Ultimaker the feeder winds up ripping a gash in the filament and I'm forced to throw away a large chunk of filament (the amount going from the feeder to the extruder). So 2 questions - Is the feeder motor too tight? Can I loosen it? Should I? Is there any way I can prevent it from chewing up the filament? I'm assuming it's happening because the motor is trying to run too fast? On the GCode side - Is there a solid guide to ultigcode? I've looked through the reprap wiki and I understand basic GCode but I need to find out which settings will work best with this particular printer. The GCode below is what I've been using with the Makerbot - I've noticed that the files that come with the Ultimaker set E values for each step - I was hoping to 'set it and forget it' via something like this: M108 R4.0 (Set Extruder Speed) So it just stays constant - is this possible and how do I find out which numbers are appropriate? According to the reprap wiki this command has been deprecated in favor of M113 but I haven't seen that in any of the example gcode files. Instead it looks like there are maybe machine presets set with 'skirt' or 'wall-outer' - there are also commands to set different layers - and I haven't found documentation for these commands - does it exist? Is there a way to find out how to set the E value for each step aside from guessing (and potentially blowing through filament)? thanks M73 P0 (enable build progress) G21 (set units to mm) G90 (set positioning to absolute) G10 P1 X-16.5 Y0 Z0 (Designate T0 Offset) G55 (Recall offset cooridinate system) (**** begin homing ****) G162 X Y F2500 (home XY axes maximum) G161 Z F1100 (home Z axis minimum) G92 Z-5 (set Z to -5) G1 Z0.0 (move Z to ÔøΩ0?)
