I’m new to 3D printing and have so far made pretty much every conceivable mistake. I’m going to attempt to chronicle them so that other newbies jump over the dumb things I’ve done.
The Replicator Dual is by far the most popular of Kwartzlab’s 3D printers. You can make lots of cool things with two extruders, but if you’re a novice usually your designs are mono coloured. When it came time to print my model, two different colours of filament were loaded into the replicator.
The black spool is loaded in the left extruder, the green is loaded in the right. I want to print my model in black, so I’ll just use the left extruder. Easy enough, right?
Well, not at first. If you open up the make dialog in makerware, it looks like the extruder used to print is an immutable property:
After seeing this, went through the replicator’s menu options to see if it had to be set there, to no avail. I also failed at googling. I went back to makerware and just clicked on random things until I found that you can set what extruder an object is printed with in the “object” menu.
When you open the Make it dialog again the extruder will be switched to left.
A very short solution to a very dumb problem. I hope that this is helpful to someone.
