Re: MINTEMP triggered!

Almost certainly, that means the extruder thermistor has failed or become disconnected. Unplug the thermistor at the extruder and measure the resistance from pin to pin. It should show about 100 kΩ resistance at room temperature: 135 kΩ in my cool basement, less in a hot room. If it's completely ope...

Re: Build-A-Bomb

the finished model will look so real Nowadays, even these make folks nervous: https://softsolder.files.wordpress.com/2011/10/img_0682-finned-co2-cartridge-array.jpg?w=240 But what else can you do with empty CO2 cartridges? The fins test thin-wall printing, if you need a justification: http://softso...

Re: Support doesn't break off clean...

what am I doing wrong? Probably nothing much: supported undersides are like that and that's the way they are. You can get a perfect sphere (well, as perfect as a consumer-grade 3D printer will allow) by splitting it along the equator, printing both hemispheres flat side down, then gluing them toget...

Re: Seasoning a nozzle?

coat the outside of the nozzle to prevent that thing where PLA curls back around and sticks to it. My old Thing-O-Matic had a PTFE-coated nozzle and ABS stuck to it like, uh, glue, so I doubt that a well-seasoned metal nozzle will fare any better with PLA. The ABS wiped off easily and left no resid...

Re: Solid thin walls, how please?

nozzle output width in relation to model profile It looks like the settings call for two perimeter threads. If those threads are 0.5 mm wide, then the thinnest solid wall will have four threads and be exactly 4 * 0.5 mm = 2.0 mm wide. If your model has a 2.25 mm wall, then there must be a 0.25 mm g...

Re: printer bed stops half way before print

try to print something on pronterface by importing stl Both of those STL files are non-manifold: the marker has no bottom face (*) and the astronaut has self-intersecting faces and non-manifold vertices. While it's obvious to a human how those model should print, bad STL files cause slicer programs...

Re: Do the timing belts ever wear out?

the belts wearing out? In this lightly loaded application, those belts should last just slightly short of forever... [grin] What's more likely is that the little tiny screw that should lock the pulley to the motor shaft has worked ever so slightly loose, allowing backlash that offsets the threads f...

Re: Heated Build Platform is dead

I unplugged the harness at the bed and measured the voltage with a meter and got 1.8 Volts. Caution: unplugging widgetry with the power on can produce Very Bad Outcomes. In particular, unplugging a powered stepper will almost certainly kill its driver chip and scrap the entire RAMBo. The HBP isn't ...

The early nozzle valve patents recently expired, so we can expect the first implementations from The Major Players by next year. [grin]

The trick will be maintaining nozzle positioning accuracy without weighing down the extruder carriage...

Re: Still considering buying the M2

3d representation of interior and exterior architectural layouts. Can this printer do that well? At least as well as any other DIY 3D printer and far better than most, I'd say. All DIY 3D printers have a rather coarse resolution that affects the results: in round numbers, the smallest feature will ...
