Re: setting up a small 3D printing shop with a M2?

IMO, Shapeways and their ilk have knocked the stuffing out of any possible home-shop 3D printing biz: they have better production processes, a much wider selection of materials, and nearly the same turnaround time. Staples has been making noises about entering the point-of-sale retail end of the biz...

Re: OD to size, ID always undersize

Any ideas as to why this would happen Nophead did the definitive study on why fused-filament circles come out too small: http://hydraraptor.blogspot.com/2011/02/polyholes.html Edit: He writes up another effect: http://hydraraptor.blogspot.com/2014/06/why-slicers-get-dimensions-wrong.html You can me...

Re: Another ABS Help Post

more aggressive zits. Comparing the "new" column with the "old" column, the zits below the layer shift appear in exactly the same locations and seem to be only slightly larger in the new one, so they're baked into the G-Code. That, plus the blobs on the skirt extrusion, suggests the retraction sett...

Re: Using ABS

Why not just print a line in one direction, or wipe it coming back? I've seen Slic3r do that on rounded shape with a tail (think of an elongated paisley): as the tail became thinner, the number of perimeter threads decreased, ending with a single thread extending along the tail from one side of the...

Re: Using ABS

What defines the X and Y resolution? Is this fixed? That's what I call "the big lie" when somebody asks about "50 micron resolution!" during one of my presentations. The extruded thread width defines the XY resolution, not the motor & belt positioning resolution and definitely not the Z axis resolu...

Re: Firmware upgrades

So, what happens to the bootloader if I upload the new firmware file? Does it get erased? The bootloader lives in a separate, protected section of Flash ROM; it handles the back-and-forth required to load the Marlin (or whatever) program into the rest of the Flash. In theory , you can't blow the bo...

Re: M2 Replacement Parts

Is there a filament guide (close to the spool) that has the same receptacle for the guide tube? Mine is blocky and fits a slightly larger 1/4 inch OD polyethylene tubing from Home Depot, but you can tweak the OpenSCAD source to suit your preferences: https://softsolder.com/2013/10/28/makergear-m2-i...

Re: E3D V6

people like me who have built and programmed microcontroller boards from scratch See, that's your problem right there: you're too good at this stuff.
