Yes. Exporting is disabled for purchased items. However, if you send an email to support@matterhackers.com we will be happy to provide you with the STL files.

@MacHume,

Ryan was referring to the Edit button in the upper left of the Library view, not the Edit button below the 3D view of the object.

@Panacaguy and @jvhilton,

Remove the following line from your End GCode, if it is there.

G28

Do not remove any lines like the following, but do make sure that all letters on these lines are uppercase.

G28 X0
G28 Y0

G28 is the command that tells your printer to home. It is safe to home the X and Y axis, but when you issue G28 without any parameters, it homes all three axes (including Z) and crashes into the bed. I'm not sure why the lone G28 would be in there in the first place. Nevertheless, this seems to be the case for some people.

I notice that you have Wipe on Retract turned on. This option backtracks the nozzle whenever a retract is done, in order to wipe excess filament off. In your case, its probably unnecessary and may be causing some of your issues.

Unfortunately the forum doesn't allow arbitrary file uploads yet. You can still post them using another service like Dropbox or Google Drive.

Lets see whats going on with your retractions. Go to the layer view, open the display menu on the left, and click the boxes to show moves, retractions, and extrusion.

Its not a bug, but I understand your confusion. The filament settings page only shows the settings for the first material. Settings for the second (or more) materials are taken from the presets. Do you have any suggestions of a better way to handle this?

You also raise a good point about the custom gcode variables. I'll see if we can add that.

Sounds like reversed polygon normals to me. Basically your STL file was not generated correctly. Try running it through NetFabb or MakePrintable and see if that helps.

Large ABS prints are hard. Is that ABS juice your are using on the bed or glue stick? If its the juice you are already on the right track. You can try bumping up your bed temperature a little, to 90 or 100 C.

The other thing you should do is put your printer in some kind of an enclosure to keep it warm. Something as simple as a cardboard box will do. This will help a lot with the layer seperation, like you are seeing on the left side. When we do this it usually gets to 100 - 110 F inside the box.

Here's the link to that article, in case anyone else is looking for it.

TROUBLESHOOTING FOR MATTERCONTROL PRINT LEVELING

In theory you should do the calibration while hot, since the length of the hot end will change very slightly due to thermal expansion. But in practice its easier to do it cold because then you don't have to deal with plastic leaking out of the nozzle.

This is a known issue and it will be fixed in 1.5.1.

1.5.1 is currently in alpha (for windows only), so you can try it out now if you want to.

Tod, there was some work being done towards that, but it is incomplete right now. @LarsBrubaker, is this a possibility in the future?

Sounds like you are running into this issue, or something related. Did you read that thread? Did it help at all?

Did the filament expand to 3.59 mm because it was melted in the hot end, or did you actually have a bulge in the filament that was that large? If your filament actually has fat spots, its obviously defective. You should call or email us with your order number and we will replace it.

What do you mean by surface cracks? Can you take a picture?

@TodABen Upgrading Mono may help (we recommend version 4.2), but it is likely that you are running into this error, which we have been aware of for some time. To check, run MatterControl from the terminal.

If you are looking for a replacement for your PC, you should consider the MatterControl Touch, a standalone Android powered printer controller.

Moved this into it's own thread. Please do not hijack other people's threads in the future.

The MAKEiT meets most of your requirements, although the manufacturer specifies the maximum hot end temperature to be 275 C, not 300, and the bed size is slightly smaller than you want.

My question for you is, do you really need a second extruder? Most people who are getting started think they will need dual extrusion for support material, but in most cases it is unecessary and more trouble than its worth.

1. I assume you checked all of the things listed here. It doesn't make sense for it to be skipping steps if the weight has been reduced. Something else must be going on.
2. In your settings, do you have the right nozzle size and filament diameter?
