I have 130 hours on my new Predator and made a video of what mods I have done so far.

I have made about a dozen prints in GizmoDorks black PC with great success with my MakerGear M2 and E3D. I have even successfully printed a 160mm tall part with 99% infill that was 0.5 lbs of PC with no warping. I did make an enclosure though - I don't expect it will work well without one. I can't get big ABS parts to work well without one either though.

With a 60C chamber, my hot end has run for 50 hours already and has been cool. But if I wanted a hotter chamber, then water cooling is the way to go.

I am successfully printing GizmoDorks PC on my MakerGear M2.
I consider everything that I list as important, so don't skip any step:
Bed heat - at least 110C. I am using 120 now.
Three layers of purple glue stick (I had a failure with one layer).
Print speed - 40 mm/sec. I have not tried to go faster, and don't plan to.
Hot-end temp - I am using 290C.
No fan should be used on the part.

Here is mine:
The heated bed heats it up. I am running it now with PC filament at 60C inside using a bed set to 120C.

I think this is most useful for a printer that is in a heated-enclosure where the ambient air is not all that cool to begin with. I am printing PC now and my chamber is at 60C and so I think water-cooling would be interesting.

I bought it a while ago and am still using it.
I really like it for the layout and manual support ability. As for the settings on it - I like most of how it handles things. I like how Slic3r organizes filament separately from the printer settings better though. Simplify needs to do that, but doesn't seem to acknowledge it as a weakness.
I tried using Slic3r 1.2.6 today and it is good and I am

I have only tried the eSun PETG that Intservo sells. I print at 245C and my bed as been at 110 - though I see others are using less, so I may turn that down to save on warm up time. I am using 0.2mm layers, and am under the impression that it does not work optimally with much thinner layers.
I have no had any curl or cracking like I do with larger ABS objects. I even built a cabinet to help by A

I had delaminating on lager prints, until I changed filament supplier. What a difference!
Now my ABS doesn't detach from the bed anymore, even the tiniest prints works fine without a brim, and delaminating on high prints doesn't happen either.
So, filament quality also influences these properties a lot!
It is possible that the new brand works at a lower temp. You could up the te

That is also what I bought, but I just discovered that you can buy Misumi SFU10-500 for ~$16.50 each. They are H7 ground and not stainless. Comes to about $13 more than the McMaster. I have no evidence they are be

I printed the IGUS models and it was not snug enough. The ones that I linked to did fit well.

Would you say printed PLA can last for hundreds of hours of printing? I am about to rebuild my Printrbot tonight with some, and hope they last.
BTW, IGUS has a genuine 3D model on their website. I am printing some now, but not sure they will fit yet. I will know in a few hours.
I have already printed these in 8mm and 10mm and they seem good:

If you use plastic bushings, you can get the IGUS, or print some:
The video has 10mm, but I also made 8mm.
Don't use aluminum shaft! You can buy ground steel shaft cheap from McMaster - $30 for 12 feet.
Don't buy stainless. All machines are steel - lathes and mills. They are not stainless.
I am building a TAZ:

I gave up and ordered a RAMBo and will do dual extruders. I want to use the new QU-BD X-Truder dual (is 12oz including two NEMA-14 motors). When someone has a 4-extruder board (and when Slic3r supports it), I will upgrade the electronics and do back-to-back dual extruders.

What do you-all think of standard bearings vs the $5.95 each plastic bushings they use? It is like $65 vs $15.

One does have to wonder though - you can build this for $800 or I could have just ordered a 12x16x10" RigidBot for $855. They claim Oct delivery.

I have just about everything ordered. ~$637 so far. There are just a few things I did not include in the cost - like the wire. Also I will get the power supply and power cable from an old PC. I am going to say that one can do it for under $700.
RobTheSlob changed my life when he showed me - saved ~$80 over McMaster.

Thanks. I found it. They have many nuts. Some you can put in after assembly, and some only before.

Today I ordered everything to make an OpenBeam 1.4, and it is costing me about $600. I could do it for $550 if I didn't get fancy ACME screws and a RAMBo and stuff. But now thinking about it, I don't see why the TK-0 would cost much more to make. The heat bed costs more but not much else. It would take a lot of work to figure out the true cost, but I spent 20 minutes on it, and I am thinking abou
