3D printing...

I woke up this morning to enhanced leveling knob covers:

Man, but do these make leveling the bed sooooooooooooooo much easier. I also added the strain relief while I was in there.

Print the calibration cube ASAP. Otherwise you're starting from an unknown.

Done. It measured out at 19.8 on all three faces. I increased steps by 1.01 all around. Printing a second cube now. I'll calibrate esteps after I've rechecked dimensions.

 

[The Chairman]

Not sure why you're having to re-level so often.

Seeing the z axis resting on the controller box was a good indication.

Shell number provides strength, infill provides rigidity. If a part needs to be stronger, increase the number of shells (solid outer layers). If the part needs to be rigid, increase the infill density.

Not sure why you're having to re-level so often. Unless you're torquing it all over the place getting prints off. But a thin spackle knife. They work great for coaxing parts off the print bed.

Print the calibration cube ASAP. Otherwise you're starting from an unknown.

I didn't print the calibration cube.
I printed a BCD flange from the design I did with FreeCAD and assembled it against the original BCD valve cap. The thread fit perfect. I assume the calibration from factory is OK.

Does any one has the specs of the BDC valve flange thread of the Mares BCD ?
I'm trying to model the BCD flange of the Mares BCD.
I did a test print but it fits too tight.

Have you checked to see if your flange holds air, yet? Most of my printing is pretty pourous.

BTW, the calibration cube came back at all 20.0. Awesome.

One BCD flange is already installed in one BCD of the school. Pretty water/air tight.
I'm printing ABS 100 % infill.

My girlfriend just found out that her teenage son is 3D printing a handle for a gun to sell to somebody online. She put a stop to that one real fast. I just wonder what else he's planning to print or already printed that she doesn't konw about.

I believe there are plans to print full guns and AR-15 parts. So a gun handle is pretty Innocent.

When I did the dgx style, I just made liberal use of a micrometer and bounced my measurements off of standard thread pitches... I also printed a 3mm tall section of the threaded portion for trial and error fine tuning of diameters/tolerances
