Filament recommendation?

I'm printing out some prototype game pieces - figurines that are to be stacked/piled up on one another. Problem I'm having is PLA is so hard and smooth that they slide right off each other. Miniatures/figurines that come with board game nowadays are somewhat flexible, and have a slight rubbery-ness ...

Re: Any thoughts n the E3D Titan extruded?

... I can go 1.75 or 3mm without hassle, and can print flexible without a $300 upgraded extruder. I'm curious how the 1.75 / 3mm is working out for you. Also, the flexible filaments. Specifically, are they 100% stable in operation? This would certainly be a #1 selling point for upgrading my rig. Th...

Re: Any thoughts n the E3D Titan extruded?

For those working on TAZ mounts, I designed and posted this on Thingiverse a few months back, its been working great for me. I'm sure it can be improved, but I've had zero issues with it so far: http://www.thingiverse.com/thing:1523837 Love to see what others come up with. Like I said, I'm sure mine...

Re: Evening out bed temperature?

Are you saying you're using aluminum INSTEAD of the PEI glass? Hard to understand it exactly. I'm talking about removing the heating element from the glass, attach it to the aluminum, then attach the glass to the other side. The aluminum would help distribute the heat more evenly across the glass.

Evening out bed temperature?

My bed temp is horribly uneven. I know where I cannot have ABS parts on the bed, because anything there always peels. Has anyone tried putting a thick sheet of aluminum or copper between the heating element and the glass? I can only imagine it'd help spread the temperature difference out.

Thoughts?

Re: e3d v6 owners searched for print comparison

I've been using the E3D v6 as well as the Volcano, both on a Titan extruder. I was able to reduce the weight of my X carriage by about 25% (and I'm using a full sized NEMA17, havent yet bothered to mess with the smaller version the Titan is supposedly capable of using - if I do that I can reduce it ...

Re: Why not heat the bed with more power?

The answer is quite simple: Ok, I'm coming late into this thread, but to answer the previous question about "@127", it's actually 255. Marlin has its own soft PWM implementation that runs over 127ms "frames". So that requires the PID CO to be shifted 1 bit to the right (effectively dividing by 2, r...

Re: Capacitive Auto-Leveling on TAZ 5

If you have a nice design, it would be awesome if you shared. The issue with that is the fact I had to extensively modify the Marlin firmware to make it work. To make the auto-adjustment work I had to add a stepper. Since the Rambo board only has 5 stepper controllers, I had to hijack the second ex...

Re: Why not heat the bed with more power?

That is more 80% power at 50% of the time actually. 80% to not blow the fuse and give it recovery time. (AKA - Not melt.) I imagine the 50% is for the other part in the circuit that is NOT the heat bed. Explain where 80% came from? And if it's 80% to not blow the fuse, then only having it on 50% of...

Re: Why not heat the bed with more power?

So first, a little explanation for non-coders. PWM means Pulse Width Modulation. In laymans terms think of turning a light switch on and off thousands of times per second. If you had an "old fashioned" incandescent light bulb, if you were able to flick the switch that fast, the light would appear di...
