Happy new year all!

+1 on the not being able to open the V2 z bar ends, it crashes both S3d and my explorer window when i open a folder with those files ( i get stl preview from inventor )

The price of M3 and M5 black nylock is ludicrous. I ended up getting a couple of 100 packs from ebay, and i am going to list them when I'm done. Evidently those black nuts are for some RC axles.

My box of parts is pretty full at this point, im just waiting for some "spare" time to cut the frames.

You had wanted to know, a while back, what motor I was using for the 3 screw Z stage, I ended up using http://www.robotdigg.com/product/29/Nema17-60mm-1.5A-high-torque-stepper-motor

Hi,

I've finally got to the stage where I can do some printing, with my build.






I'm currently printing eight times faster than I would on my Prusa I3, and it's giving much better results.



Which is surprising considering I'm printing onto a piece of half inch ply, and I haven't done any calibration of the extruder or hotend yet.

So well done Carl, I'm very impressed with your design...

 

Hi,

Yep, I'll run dual extruders the new thermistors turn up, I only have enough to run one hotend at the moment.

I had to make the carriage longer to accommodate the cooling for the hotends. Also I keep bashing the X endstop (or is it the Y) from homing the wrong axis first, I'll have to figure out a way to put the endstop on the carriage to solve this..

Yep, I put a V-slot mount on an air-tripper filament drive and put one on each side.

 

I like the extra bracing you put at the bottom corners, I'm going to add that to mine. Those cubes look great. I am just waiting on a digikey order and a mightyboard. Any video from that webcam?

 

I was at my local microcenter today and saw http://www.microcenter.com/product/442237/Sky_PETFilament_175mm

Might be easier to get this into Canada. Little pricey, as the Esun was same price for 1KG. I am not a fan of those narrow 1# spools, I use a tabletop roller for my filament

 

Hi,
I'm using Aluhotend's, I originally had them on your dual carriage design, they fitted nicely although I had to reduce the groove mount by about 1mm, but then I couldn't manage to fit any cooling in. The smallest fan I have is 40mm and it didn't fit, so I expanded the carriage to get the fans on. I'm still tweaking how it all fits, and what works best.

I got Marlin to home front/back (my Y) and then left/right, but occasionally I manually home left/right before front/back, or worst when it is in the left/right home and I home front/back it will bend the home switch, even more than it is bent now. Also my kids will be using the printer, and they are more careless than I am, it would be better if it's fool proof.

 

Hi,

The extra bracing on the front is to hide that gaps where extrusion joins, I didn't manage to cut it millimetre perfect so it has gaps everywhere

I'm still working on the camera. I normally sit it next to my older printer so I have video to look at when things go wrong, but when I sat it next to this machine.... Well it looked up at the underside of the base. I built the mount for it, but now it is to close and all the images are blurry, I'll have to look at getting a different lense for it.

 

It may be a little more subtle than this but PETG is basically PET but with the addition of Glycol in the mix. It certainly makes the mechanical properties a whole lot different when it comes to thermo-forming.

Tweakie.

 

I have absolutely no idea but if it's like everything else then it's the one they charge the most for.

Tweakie.

 

Carl - I just got back to this and dnld your latest Zip file. After figuring out Sketchup and loading STL files I am presented with a new challenge - DX files. I figured out it is a zip file and I did open the file with WinRAR but then a new challenge appeared SMT file. I would like to open them in Sketchup and I am using Repetier host to the printer. And I have no idea what to do with the DAT files.
Thx
Also - how critical to the design/performance is 20x40 extrusions vs using 20x20?

 

do you know which LED strip you made room for? The 5mm 5050 RGBWW would be fun.


As far as what the G does i dont know, I was printing on 70C glass with the aquanet #5. 240-245 nozzle temp, I used no fan, but removed my enclosure. Good adhesion, very little warp, good release from cooling plate. two warnings, It shredded the PTFE liners in my hot end, I used 3 inserts for the parts I printed. I got on average 20hours from one before I got some jamming. I have since installed some all metal, stepped bore, thermal barriers and have yet to get a good PETG print from it. I do think that the PTFE that I sourced was PFA, so many brands of teflon with different properties. I am going to try switching to a straight bore tube before going back to the ptfe, although I have two new sources of what I hope is ptfe. Second issue, I am getting some extra drag on my guide tubes in the last 20% of the spool. Esun does a good job of making sure the spools have a large center diameter, but there is a noticable curvature. I also just remembered that the spool has been out a while, I need to ask esun if it soaks up moisture. It is pretty dry here in NYC.

With any luck I should get the frame assembled this weekend.

 

I do think that the PTFE that I got was actually PFA, another brand of less thermal resistant teflon. Also the hot end in your E3D should be all metal? the ptfe in in the cold end? I know very little about the bowden setup.

edit. I am printing with a makerbot clone, the ptfe extended all the way into the nozzle.

 

I think I stumbled on a deal. Does anyone have any familiarity with there steppers.
NEMA 17 BIPOLAR STEPPER MOTOR, KL17H248-15-4A, 76 oz-in
from: http://www.automationtechnologiesinc.com/
direct to their site for combined shipping 5x=$58.44 >>>> 6x=$62.03
shipping is cut in 1/2 adding 1 more. good to have a spare.
the only potential issue is they r 48mm long, but it appears there is plenty of room for them.
Might there be any other issues??????

 

The 90 degree brackets from the part store use M5 x 8mm, the 10mm's are too long. Ordered some proper black ones, going to head to home D for some temp one tonight. So far things have gone together pretty easily. Printed parts are spot on so far. and have needed no post processing. I did fail to measure my stairway, its a fairly tight spiral, and I had to take it outside to get it downstairs. whoops

 

I also never looked at the description for the brackets, it clearly states 8mm. Parts store is out of stock, http://store.makerstoolworks.com/ha...-x-8mm-socket-head-cap-screw-black-bag-of-20/ is anyone needs.

My leadscrews have 575mm of thread, with 20mm or so turned down to 5mm shaft, the tops will be completely un-constrained

 

I was about to order my rails yesterday and SHOCK prices jumped by 28%. Can u believe that?
OK so I will start printing and wait till they come to their senses.
I HAVE a question about infill. Does anyone have a recommendation about % & type to use for these parts. I'm starting with the extruder. I have no clue.
