What is the difference between STL and OBJ files and which one should I use?

One of the CAD programs I use is called TinkerCAD, which lets you export your design in either STL or OBJ form. What is the difference between these two file types? And which one is better to use?

Belt Tensioning

I have printed off some upgrades for my Anet A6 for tensioning the belt on the Y and X axis. I was wondering how much deflection the belt should have. I would think being to tight will stress the machine.

Is it advisable to use additional external fan(s) for printing PLA?

I was wondering if adding (an) extra fan(s) (not connected to the printer, but blowing on the print area) could improve the quality of PLA based prints(printing at 210 C). The printer already has a built in fan with a fan shroud that directs air to…

In Fusion 360 how do I select an entire 3D object, not just its sides or faces?

I'd like to mirror a triangular prism I made. However, whenever I select it I am only able to select the faces or sides. Is there a way to select the whole 3D object to move or mirror it?

Extra data appended to the Y values when issuing `M92` & `M500`

I am still trying to dial in my Anet A8. The Marlin firmware takes too long to scroll through the axis settings when I change them, so I use Repetier Host instead issuing M92 followed by M500. I noticed in the log window that X goes in as typed but…

Over-hangs in prints

I would like to ask this in more of a general sense than anything, just for people to make note. I am printing out things for people and some files have some edges hanging out the side. I always worry, since it is printing in mid air, that it would…
