mark-hale 0 Posted November 2, 2013 in Print causes nozzle block I have just created a file with solidworks which loads fine in cura but when I go to print it on my Ultimaker2, pretty close to the start of the print a large blob of PLA gets placed on the bed and then blocks the head. What is the best way to diagnose the issue, assume I need to look at the code. Sorry totally new to this so venturing into uncharted waters Share this post Link to post Share on other sites
illuminarti 16 Posted November 2, 2013 in Print causes nozzle block Generally speaking, Repetier Host is a pretty good tool for visualizing gcode, but I don't think it really understands the new type of gcode that Cura generates for UM2's now. Particularly the convention of giving extrusion amounts in mm³, not mm of feed. If you'd like to post the gcode somewhere, or http://mailto:gcode@fbrc8.com, I'd be happy to take a look.

illuminarti 16 Posted November 2, 2013 in Print causes nozzle block As I just explained in my email back to Mark, for some reason there's a weird segment in the skirt, where the gcode suddenly blobs out an extra 200mm³ in one spot (remember: this is UM2, so E coords are mm³, not mm of filament), and then carries on as if nothing had happened: I tried slicing his STL in 13.10 and couldn't reproduce it. So either, it's something about his version/settings that i didn't hit, or the file got corrupted somehow, I guess. Can't say I've ever seen this before.

mark-hale 0 Posted November 2, 2013 in Print causes nozzle block Many thanks for your help on this. For info, I tried removing CURA and then re installed it. Now when I look at that line, it is normal. Looks like I may have had a problem with the initial install of CURA. Had not altered settings since I installed the software and the only thing I can think of is I had a previous older version installed although notice that was installed in a different directory. Very odd, especially as this was the first file I have had a problem with. Gremlins I guess Good thing is im learning quite a bit now, first time I have looked at the code. Still very much a dark art at the moment but its a start Thanks again illuminarti Share this post Link to post Share on other sites
