My ToyREP! It started out as Orange...
Octoprint, 3.5" touch screen, Logitech C270 camera
Poo emoji spinners tops for z axis! :)
Volt / Amp Meter
40mm Fan grills
Inductive Z probe
120x120 heated bed
8 amp power supply
I used PLA, works fine.
Hi.. Looks really nice.. :D
I am trying to make the same, but i have a big problem with heat creep because of the low flow speed.. Have you have had similar issues or? What hotend do you use?
Thanks! Lots and lots and lots and lots of work.
Heat creep? What do you mean by heat creep? The filament getting stuck? I got new throat with tubing inside, not just metal.
The hotend is a mix of 2 different types. E3D V5 (I think) because the grooves line up with the mount. The heat block, throat, thermistor, heater at the bottom is from a V6 hotend. I had problems with sticking filament but it has gone away with new throat.
I also make faster print speeds. I moves pretty quick now... Mostly settings in slicer (I use Cura) where most settings on the advance tab are set to 20 or 25mm /sec
Hello! Thank you for the comments on my build.
I ordered the hotbed from eBay, here is a list of matches -http://www.ebay.com/sch/i.html?_from=R40&_trksid=p2050430.m570.l1313.TR0.TRC0.H0.XHot+Bed+120*120mm.TRS5&_nkw=Hot+Bed+120*120mm&_sacat=0
The power supply is from here -http://www.ebay.com/itm/272083459548?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT
Select 12V 8.5A. The picture shows the dimensions, it should be 98x130x42.
It is a very tight fit but highly recommended.
I used smaller power supply the first time through, it was too weak. Upgrading the power supply later is a real pain in the butt.
I have seen mods for NEMA17 motor for X carriage but nothing else.
Wish Branez would release more information on the ToyREP carriage he made, mostly the hotend.
Good luck and let me know if you have any more comments or questions.
Great build, looks really nice! If you don't mind me asking, have you made a heatbed according to Thorgals description or did you buy one? If the later is the case - which Power Source did you use? I was looking around for a source that would be able to power a commercial heatbed and still fit under the printer, but I wasn't able to find one with enough Power.
Also, if you want to consider an update later on for faster X and Y movement, I can highly recommend the update form Branez (you can find it in the builds) to fit NEMA motors. I have used a NEMA 17 for Y and 14 for X Axis and it works like a charm! It will also allow you to use a GT2 belt to drive these axes.
How about printing round things? Did they come out better after upgrading to nema motors?
BTW, I have added a picture of a rather round thing i made in my build, in case you want to see how the update performs.
Round things came out absolutely amazing. I have printed a lot of things (PLA, mostly, as I do not have a heat bed installed), including rather complex models like protein structures and with regards to either rounds or edges, no problem at all. Of course it takes some optimizing in your slicer, but currently, at max print speed of 75mm/sec I really don't see any problems at al and the surface finish at my prefred layer hight of 0.1mm is really great.
I asked Branez for the Nema14 stl and they have not responded.
I'd love this printer to do 75mm/sec lol
Geared steppers are the worst; need to design a stepper saver pulley...
I want the Nema14 stl please.
The NEMA14 stl actually already is in the update from branez. If you have a close look at the X-axis holder, you will notice that the holes for the screws are not fixed but elongated, which is very well done by branez, as is allows you to use both a NEMA17 OR a NEMA14 for the X-Axis. This does not work with the y-axis, I believe, as this can take NEMA17 only, but I might be wrong - easy to check, just measure out the holes for the screws in the STL file for the Y-axis holder and compare to the hole spacing you can find in pretty much any description of NEMA17 on ebay.
I have added some picture of my update and a more detailed description of how I made the update in my build description:
Hope that helps!
Hey, one last thing, maybe 2 -
I ordered 2 NEMA14 motors for this, also got 2 NEMA17's - regardless, what size pulley are you using and what spacing did you use on the belt? 2? 2.5? Going to have to order new belts, might as well match the pitch and teeth that you got, so I can then ask for your steps/mm settings :)
One of the advantages of having the Nemas installed is being able to use GT2 belts - so these are the ones I have used, together with GT2 20 tooth pulleys - I hope this info helps!
Have you tried both NEMA14 and NEMA17? I assume NEMA17 would be better?
I have talked about this in the description I have added to my build - I have used NEMA17 for the Y-Axis and have used NEMA14 for the X-Axis, since there is quite a difference in weight with NEMA17 being a lot heavier, so I did not want to put too much weight onto the X-Axis. I guess it might be possible to use NEMA17 in the X-Axis, but it would make it quite heavy on one side, and I do not know what the consequence of that would be. Feel free to try it! I am, however, very satisfied with the NEMA14 on X and NEMA17 on y.
Awesome, I found the STLs for NEMA14/17 for the X and Y axis in Branes files.
