Lcd mounting brackets

Postby bplemmons » Tue Apr 23, 2013 7:39 pm

I have just posted the LCD mounting brackets for printing. Mine cracked when I put screws in them. these are wider too. More room for the screws.

Here is a spool adaptor for the Rostock Max when using the Seemecnc filament spools with 52mm ID:
http://www.thingiverse.com/thing:84813


Print one for each side of the spool. This works really well along with Av8r RC's spool holder(http://www.thingiverse.com/thing:60750.)

Now we need a variant for the Taulman 645 spool. It's got a much smaller hole, and won't fit the stock holder or the http://www.thingiverse.com/thing:60750 version from Av8r. Then again, I'm using a large screwdriver for it now, which seems to be working fine.

Until someone creates something new, you can try slicing the rod and clip of Av8rRC's http://www.thingiverse.com/thing:60750 with a scale of X=.88 Y=.88 Z=1 (unlock aspect ratio) It will fit a little loosely into the Max holes but should work fine. The only question is whether the thinner section of the rod that the clip slides over remains thick enough.

Edit: Tried this out and it works great!

Here's my newest cooling design... Lowers my maximum build height but addresses some more critical areas:

http://www.thingiverse.com/thing:87117

Give me some thoughts/suggestions please. I'm just getting to the point where I can begin calibration on it so I think it's working much better than before

Some pics of it installed up now. Let me know if people would like to see additional pictures.

Hey I just loaded my tweak on jasonatepaint's LED ring for the rostock max to thingiverse.
http://www.thingiverse.com/thing:90099

The LEDs are shielded so I don't see spots anymore.

Hope you like it.

EZStruder Indicator

I like the new EZStruder from Seemecnc, but I miss watching the gears of Steve's Extruder to see that it is working properly. I made this silly little indicator and it does the trick. The STL file has the hole dia at 5mm. Its a press fit on the motor shaft so you may need to run a drill bit into the hole or scale the STL file slightly before slicing to accommodate shrinkage of the plastic.

I made a quick spacer for my extruder. It doesn't look like much but helps cut down on the noise of my extruder.

You printed the example out with a dual head? Can you go into that a bit somewhere?

This is a top mounted spool holder. I have one for SeeMeCNC sized spools and another for Ultimachines 5lb spools. It uses 4 608 bearings.

I've also created another version that combines the two. So you can use three different sized spools, on one mount. I haven't printed that yet.

Minimal design! Love it! STLs on thingiverse? You just made my day! Enough motivation now to mount it in the top! This is a three exclamation post...

Actually, it's 4 in your post, plus the additional 3, so as far as I can tell, that's 7 awesomeness. Pretty flippin awesome insofar as I can surmise .

Yup. All the files are here: http://www.thingiverse.com/thing:106977

After posting here I added another STL that combines the 67mm and the 100mm design. So if you have one long bolt you can use it for three different size spools (but, I haven't printed that one yet.)

Mounting plates for an E3D hot end, which accommodates the Bowden option: http://www.thingiverse.com/thing:137140

Should work with other groovemount heads, as long as they don't need external support for PTC fittings.

I noticed that in Flateric's thread about his 1 hour bug he seemed to be trying to print my cooling duct for the stock effector. I seem to be getting good exposure on Thingiverse, but I thought I'd drop it in here to in case anyone hadn't yet seen it. http://www.thingiverse.com/thing:134185

I tried to design it in such a way that it would cool the filament without exposing too much airflow to the hotend. My results with two of them were quite satisfactory.

It's for a 40mm fan and the stock effector. It requires 3 M3 or #6 screws for assembly and mounting.

Nice design edward. Thanks for sharing it. I'm going to print one of these out and give it a test.

I printed this out last week. The 40mm fan just came in. When the current print is finished I plan on installing this and the 25mm fan. :D

Glad to hear it's working well for you guys. As I mention on Thingiverse, if your fans aren't balanced, make sure you put some sort of dampener between the fan and the mount. The fewer vibrations the better when dealing with steppers, especially those that are being micro-stepped.

I'm dealing with some mechanical issues after the upgrade to mag-arms and an aluminum build surface right now, but once those are worked out I'll be sharing the designs for my mag-arm effector and new filament cooling solution.

When you say "balanced", are you referring to the bearing medium, or something else?

Edward, one idea I had seeing as how nicely the duct clips on and off. Is to have perhaps 3 different outlet sizes so you could switch to the one most appropriate for the type of print you are doing. For example, a general sized one, this could be the current model. A fine tipped outlet for when doing very small detailed prints such as gears and the like. And lastly a broader opening that is larger than the current outlet size for fast larger printing projects.

Edit 2013/08/26 23:25 EDT: I just realized something: what I've said below about vibrations and steppers still stands; however, since our machines are driven by belts instead of something rigid like screws or gears, the steppers are much less likely to be affected by vibrations. The belts will have an attenuating effect. But, I have read about some users experiencing vibration-induced missed steps, so I think that if your fan produces *any* noticeable shaking when powered, do yourself a favor and put a dampening gasket in there. That goes for anything that you add to a moving part of these machines. As it usually goes...better safe than really pissed off later!

Nylocke wrote:When you say "balanced", are you referring to the bearing medium, or something else?

I suppose it would have to do with the bearing. I'm just wanting to note, for those that are unaware, that vibrations *can* cause hell for stepper motors. When the rotor moves between step points it acts under the principles of a dynamic system. There are tiny oscillations around the stopping point that can be amplified if affected just right. Since the holding torque when micro-stepping is less it takes a smaller "kick" to miss a step.

So if your fans noticeably shake when powered, I'd add some kind of dampener between the fan and the mounting surface in a matter similar to adding cork between your steppers and the machine frame. You might also notice a "kicking" of the fan at low speeds (low PWM duty cycles), which could also be an unintended source of vibration, even on a normally well balanced fan. I'm pretty sure the "kicking" is a side effect of a low PWM frequency. That is to say, with the same duty cycle and a higher frequency, you can get a "smoother" output of the same voltage.

Now I'm curious: I wonder if the AVR's hardware PWM outputs are being used for the fans and heating elements or whether they are doing some kind of software PWM generation? To the code batman!

@flateric: I hadn't thought of that directly, but I like the idea. This duct is, I think, v5.2 :) The other revisions had different nozzle shapes, but mostly due to my inexperience with surface modeling in ProE. Most of my CAD work has been very manual-machine-shop oriented, i.e., right angles, some fillets that can be done with ball nose end mills, circles, squares, straight-lines, things that can be made on standard manual machines. I had to dig out the old texts to refresh my memory on sweeps, blends, and b-splines, and as I regained proficiency, the nozzle evolved.

I can comment on a fine tipped nozzle, though, from my next-gen (what I'm using now) cooling trials. Smaller orifices require more pressure to maintain sufficient flow, and fans are terrible at generating pressure. Not saying it couldn't work, but a couple of tries with something similar didn't.

I did have an idea once about cooling with an aquarium pump. I'm not sure if you could switch it with a solid-state relay to get the regulating effect. I'm also not sure if that would be bad for a pump like that. Not so much the motor, but often small pumps need to be pumping to maintain adequate flow for cooling.

I won't promise anything as the purpose of getting my printer was to aid prototyping at work, and I seem to be perpetually behind due to self-inflicted wounds. But, modifying computer files is rather trivial...I just need to think up a quick-connect feature for changing nozzles. Maybe I can create an easy-to-duplicate mating surface so that other people could develop their own nozzles with the software of their choice...
