Thanks I will try that.

Yes. Though there is a way to launch it from within RH (I'm not in front of my computer). I think it's labelled something about custom/modify profile.

You could start by simply trying to reprint what you already sliced but set the feed rate in RH to 50 (rather than the default of 100).

I've always sliced stl files outside of RH (with slic3r), then loaded the gcode to print.

Pardon my ignorance but how do I do that? Find the folder with Slic3r inb it an run the .exe?

Normal, ignore it.

Thank you for all your help I will have to give that a try. I want to try the other program too. I never thought the learning curve would be so high. I thought creating the objects in 3D would be the pain. I also get this error when I Load the object (see attached photo)

I am new at this, I have been hearing alot about SkienForge. Does this replace Repetier how does it work with it. I have been trying to do "Grumpy cat and I am haveing issues with it never slicing ugh.

The author wrote: "Using MakerWare with High Quality settings (SkienForge) for slicing." And someone else commented: "Mine turned into a big mess using KISSlicer."

So you might try slicing with SkienForge.

On second thought, if it seems to have sliced OK it may be more a factor of your print temperature, speed, and calibrations.

You'll have to try different things to improve the quality.

Yes that's exactly what I am trying to print! You think it's the object? It looked fine after slicing. What do I use if I don't use slic3r?

It looks like the failed braclet needs support material, but didn't have any sliced. Could that be the case?

Perhaps it's this object? http://www.thingiverse.com/thing:88849

If so, you may need to play with print speeds (slow them down) in order to print without support material.

Also, how does it look after slicing? Comments say slic3r does a bad job.

There is no dust there now, its between the two silver wheels. Do you think this is an extruder calibration problem I printed one object perfect (a soap dish) then I tried a coral bracelet and got an failed print twice.

Pic one - soap dish

pic two failed braclet.

Any Ideas?

Actually, can u post a picture to show us where the dust is... i am still confused to where the dust is... from the tiny hole the filament passed thru? or on the extruder? or between extruder to hotend??
i have "some" between extruder to hotend... but it's nothing. it's not affecting the print or anything.. it's just dust from grinding or scrapping.

The fan should stay on when ever the printer is. It isn't controlled through the software. That is for a fan that you can add.

Have you done your calibrations yet?

Re: How often do you need to blow out the dust from the print head?

2013-11-13T23:32:01Z

Yes it is running. Should I turn it off if so how? The fan control in the program has no effect on it.

You should be fine at 200. I would start with the extruder calibrations. Also, is the fan on the back of the extruder motor running? Sometimes the heat from the extruder motor can soften the plastic which will cause it to strip.
