DemonDeltaMicro printer

DemonDeltaMicro printer Okay so I designed a micro delta. Probably the simplest frame design of any delta so far only 5 components! http://www.thingiverse.com/thing:1874766 Only just literally got it running this afternoon, so much work needed I am sure to get it printing well, so if you decide to build one its really alpha stage at this point, but please let me know how you get on and feedback here so it can be developed. But it does print.

Printer sits on the very edge of the table again... ::o

IKR?!?!?!

I just ordered a nice 3 tier freestanding shelving unit for like $25 on Amazon. I was looking at my printer mess, thinking 'dang I need some shelves' went looking and they are not to expensive, free shipping, no reason for not having a little organization.

Also, I feel like if i look long enough at that image I will find a VHS cassette somewhere in there, lurking in the shadows...]]> Milton Delta Machines Mon, 30 Oct 2017 04:42:27 -0400 https://reprap.org/forum/read.php?178,727893,794318#msg-794318 Re: DemonDeltaMicro printer https://reprap.org/forum/read.php?178,727893,794318#msg-794318 o_lampe Delta Machines Mon, 30 Oct 2017 03:00:07 -0400 https://reprap.org/forum/read.php?178,727893,794235#msg-794235 Re: DemonDeltaMicro printer https://reprap.org/forum/read.php?178,727893,794235#msg-794235 with a pivoting bracket, so my bowden tube is now just 20cm, which experience with flying extruders suggests will have almost no detrimental effect on print quality, as the effect of bowden tube problems definitely increases logarithmically in relation to length.

I have been thinking about a delta that has a folding frame, so that 2 towers collapse towards each other with the third as the pivot, removable brace spaces out the towers for operation. your mobile machine seems like it might be a good base for that mod, with the battery pack a flat packable small delta might be pretty cool, extreme mobility and less weight than other 'mobile' frame designs. Just a suggestion, I am months away from trying it out myself (just ordered the 20/20 for a 3 foot delta, that is next).

...add a hinge to the bed and bring it in upright position before folding?

edit: Would folding be possible at all, with three stepper in the middle? If anything, you'd have to fold it 240° the other way round *gulp*]]> o_lampe Delta Machines Thu, 26 Oct 2017 03:21:13 -0400 https://reprap.org/forum/read.php?178,727893,793707#msg-793707 Re: DemonDeltaMicro printer https://reprap.org/forum/read.php?178,727893,793707#msg-793707 DjDemonD Delta Machines Wed, 25 Oct 2017 18:10:14 -0400 https://reprap.org/forum/read.php?178,727893,793706#msg-793706 Re: DemonDeltaMicro printer https://reprap.org/forum/read.php?178,727893,793706#msg-793706 Milton Delta Machines Wed, 25 Oct 2017 18:09:23 -0400 https://reprap.org/forum/read.php?178,727893,793698#msg-793698 Re: DemonDeltaMicro printer https://reprap.org/forum/read.php?178,727893,793698#msg-793698
An opportunity possibly to either repair it, maybe changing to a titan extruder as I have one lying around, and maybe a rearm board, which I also have leftover, as they are meant to be able to run marlin 32bit (unless I've got the wrong end of the stick about that) which could be an interesting thing to try (I've never really clicked with smoothieware).

Or maybe build it into a v2 of this microdelta, but this would take more time than I have. Or maybe even use the parts and try out this idea of making a large pvc drainpipe into a delta I read on another thread.]]> DjDemonD Delta Machines Wed, 25 Oct 2017 17:49:55 -0400 https://reprap.org/forum/read.php?178,727893,793696#msg-793696 Re: DemonDeltaMicro printer https://reprap.org/forum/read.php?178,727893,793696#msg-793696

If you're using an external power supply, like an xbox360 PSU which is fairly heavy, and if it sits on the bench next to the printer, the bench which also contains another 3D printer which is generating vibrations, and if you stack 3 reels on top of the machine (just because its a convenient place to put them) then the PSU can fall off the desk, dragging the top-heavy (running) printer with it:
[attachment 99171 20171025_170739_HDR.jpg]

Luckily I was sat 5 feet from it when it happened, so no large fire started etc.. I wonder if any of the main firmware flavours supports a "fallen-off-the-bench sensor" yet?

It appears the extruder took the brunt of the impact, but the top frame is cracked also. Apologies forum insisting on displaying this image upside down, please do a handstand to view it the right way up :)

Seems that 2 hours with heated bed or 4 hours without is reasonable. The Lipo monitor started beeping at 3.5v/cell and then the voltage dropped off a cliff with the BMS shutting the pack off at 3v/cell, which is probably a little low for good battery longevity but I'll know where to call it next time. Current draw is around 0.8A idle, which seems high but there are fans, arduino, piezo board, leds all running, peaks around 9A with bed and hotend at max PWM, and seems to sit around 2.8A whilst printing and maintaining temperature (more like 2.2A with heated bed off).

Printing fast makes more sense on batteries, the motors use practically no more power moving quickly, but the heaters use a lot more if they run for longer.]]> DjDemonD Delta Machines Sat, 16 Sep 2017 17:32:44 -0400 https://reprap.org/forum/read.php?178,727893,788444#msg-788444 Re: DemonDeltaMicro printer https://reprap.org/forum/read.php?178,727893,788444#msg-788444 www.thingiverse.com] but I thought I'd share this one.

A truly portable 3D printer running off lithium batteries. Should be able to do 3 hours even with heated bed on, a lot longer printing PLA onto a suitable surface cold.

You are printing in a league I am only aspiring to get promoted to. The only facets I ever see are in low-poly models, or cubes.

This copper fill is very soft for a PLA. A full kg reel is around 2/3 full of filament when it was new, so I suppose that gives an indication of the copper content.

I am really pleased with the tiny printer, what I really want now are some tiny nozzles I really want to set it up to do very small highly detailed models. Still waiting on deltaprintr to bring out some other nozzle sizes. Maybe its time to learn how to make nozzles.]]> DjDemonD Delta Machines Wed, 08 Feb 2017 03:20:09 -0500 https://reprap.org/forum/read.php?178,727893,746437#msg-746437 Re: DemonDeltaMicro printer https://reprap.org/forum/read.php?178,727893,746437#msg-746437 I don't think that it's the weight that helps, it's got more to do with the lack of warping as the plastic cools (PLA vs ABS).

More cooling should help with definition, perhaps try lowering acceleration, and nozzle temperature as well.

My test is that if I can see the facets in the original model then I'm doing pretty well (check the top of the red marvin's head, these are facets from the model). You won't be able to see them with a rough surface finish though.

Definitely get a couple of those fans, they are worth it. They are only 5V, but I've run them at 12V with no issues. No failures yet (unlike just about every other fan I've tried).

That printer of yours is really showing results. I like the way it's going.]]> nebbian Delta Machines Tue, 07 Feb 2017 22:08:10 -0500 https://reprap.org/forum/read.php?178,727893,746417#msg-746417 Re: DemonDeltaMicro printer https://reprap.org/forum/read.php?178,727893,746417#msg-746417 [attachment 90151 20170207_235714.jpg]

But where I'm gaining as its heavy and doesn't curl on overhangs, I am losing at the corners of the eyebrows as the first overhanging layer droops. I reckon I could knock the extruder temp down a bit more. That fan I found on aliexpress $10 plus $8.99 shipping so probably worth getting a couple to save on postage.]]> DjDemonD Delta Machines Tue, 07 Feb 2017 19:04:17 -0500 https://reprap.org/forum/read.php?178,727893,746172#msg-746172 Re: DemonDeltaMicro printer https://reprap.org/forum/read.php?178,727893,746172#msg-746172

0.3mm nozzle, 0.06mm layer height, cheap red ABS, directed cooling.

Still have that F!@#$%^ filament droop inside his right eye.

I realise that it goes against the ethos you have of keeping it super simple, but a layer fan will improve results by a large amount.

I have a spare 30x10 sunon fan that I could send you, along with the STL's for a shroud that snaps into it if you like? I really rate those fans, they are excellent. By the looks of things there might be enough room to mount it onto your hotend somewhere?

Edit: I had a look at your effector/deltaprintr hotend, and think that the fan should be able to be mounted on the opposite side of the heatsink, stood off from the fins by 5-10mm, and everything should work. There appears to be enough room for everything to fit.

It's amazing how many parts of the printer get tested by this model. On the surface it looks easy. Getting it spot on perfect everywhere, however, is quite a challenge.

Will try a 100 micron one this evening.

Much appreciated. Looking forward to it :)-D

Okay so 0.1mm is not my friend.
[attachment 90091 20170206_234628.jpg]

Curly overhangs on his "gentlemans area" the droopy filament in the eye socket and an eyebrow that looks like he got drunk and his mates decided to play a prank on him.
That being said maybe with a bit more intense and directed cooling which this printer lacks, or maybe try fewer perimeters, what do you think?

I also printed this one on the kossel XL at 60 microns, he's not that great but he is a 50% scale version.

[attachment 90092 20170206_235232.jpg]

I'm on a mission to show the UM3 that 60 microns is doable.

Just printed this trio of Marvins, ABS, 0.2mm layers, barely any fan at all.

To bad, Rich Cattells FW never made it mainstream. Stupid pi$$ing contests I've often seen in Open Source projects.

What do you mean with barely no fan? I'm ABS newbie and always thought, you must not cool the print. Or do you refer to hotend cooling?

Yes but nothing to stop someone forking it and developing it, I'd be tempted if A) I had the time, B ) I could code worth a damn. But to be fair unless you want your firmware to support some really recent things I can't see any reason not to use it on a arduino 8bit based delta, it prints wonderfully, can do autocalibration if you can be bothered, but since you can define all the parameters you might need to calibrate a delta really well, and manual calibration using least sqaures calc is so easy, I don't see any need to move it forwards right now.]]> DjDemonD Delta Machines Mon, 06 Feb 2017 05:50:15 -0500 https://reprap.org/forum/read.php?178,727893,745797#msg-745797 Re: DemonDeltaMicro printer https://reprap.org/forum/read.php?178,727893,745797#msg-745797
ABS benefits from cooling at a very low level say 15-20% of the output of 2x30mm fans, on this printer I use a 60mm fan from the side as the effector is far too small for a fan mounted on it, and barely run it, I set fan max to 25% in slic3r, at 100% the 60mm fan cools the hotend down faster than it can heat itself.

But for bridges and overhangs etc... I'd blast them with as much air as possible.]]> DjDemonD Delta Machines Mon, 06 Feb 2017 05:30:11 -0500 https://reprap.org/forum/read.php?178,727893,745778#msg-745778 Re: DemonDeltaMicro printer https://reprap.org/forum/read.php?178,727893,745778#msg-745778
