Slicer fail

[ketil]

I remain unimpressed by your software, so consider this my final bug report as I shelve it. In my opinion, Creator bears the markings of something written in a rush, not much tested, and never put to real use. It just falls apart in my hands.

As discussed earlier, my extrusion multiplier was probably set too low. I'm familiar with slic3r, so I recalibrated the multiplier with slic3r as described on https://github.com/alexrj/Slic3r/wiki/Calibration and proceeded to slice the same single walled part in Creator to compare the output using the same multiplier.

As it turns out, Creator simply fails at slicing this part: https://github.com/ahmetcemturan/SFACT/ ... _40x10.STL

The only plastic that was deposited was the skirt, and then the nozzle was lifted and end.gcode commenced Here's an excerpt of the gcode (I'd attach the gcode, but the forum doesn't allow the gcode extension):

Oh, and Creator 1.0.4 hangs hard when I try to register with my license key. I've tried several times, running it from the desktop icon, and from the command line with and without sudo. Ubuntu Linux 12.10 x64.

I'm glad you're starting to get some better settings figured out for your printer regardless of what software it is. There's some things for 3D printing that you will need to calibrate regardless of what program you end up using. The extrusion multiplier was a start, but I also think some experimentation with the temperature might serve you well based on your previous results.

Can you post the profile you are using to try to slice that single walled part? I tested it with Creator on 3 different machines using the standard M2 profile and I get perfect results each time (see screenshot). I even had another user test this and he gets the same thing. I'm guessing you might be using too wide of an extrusion width for the thin part your are trying to print. If the width exceeds the wall thickness, the slicer won't print there since that would mean putting down plastic outside of the object and is generally not a good idea.

About the registration, do you have any other machines that you can try to activate on? I'd be happy to help you troubleshoot whatever issue you are having, but knowing if it's specific to that one installation might be a good starting point. I have several Ubuntu installations here that I can compare with.

And I'm sorry you've had a bit of a tough time getting started with Creator. We're here to provide support if there's anything we can do to help. And I can assure you, this was not a rushed development. It was almost 3 years in the making.

OK, I think I understand the problem. Sounds like this thin wall issue is about the same that has been worked on in slic3r for the past year and a half:

https://github.com/alexrj/Slic3r/issues/24
https://github.com/alexrj/Slic3r/issues/261

I don't have the profile I used here, but I think the only settings I've changed were the multiplier (set to 0.95) and layer height (set to 0.2). I guess both of those will have increased output layer width from the default values.
