Re: Fuse Keeps Blowing In Power Supply - 10 years ago

@slymike, I wish I had known that before I sent it back. My build has been put on hold. @ShadowRam, good observation. Short answer, those aren't my photos.

Re: Wades Geared Extruder - 10 years ago

Thanks for the tip Brent, but I am looking in the silicone O-ring/washer option because I've had bad luck with springs.

Re: Wades Geared Extruder - 10 years ago

Thanks, what about O-rings?

Re: Wades Geared Extruder - 10 years ago

I tried a few different springs, but couldn't find anything that worked. I am not looking into the silicone O-rings. I went buy Lowes and Home Depot, but I couldn't find anything. Are you guys talking about the rubber faucet O-Ring?

Re: Wades Geared Extruder - 10 years ago

Sorry for the late reply guys. I got sidetracked and just now remembered I posted this question. I should have sometime this weekend to play around with it a bit. I have been building my 3D in my spare time, which is rare since the birth of my daughter. I think I bought my kit back in December of 2011 and if I remember correctly there were two different sets of spring. I'll check the other s

Wades Geared Extruder - 10 years ago

How tight is the idler block supposed to be for the Wades Geared Extruder? Is it supposed to be so tight that the spring are completely compressed?

Re: Z Motors and Threaded Rods - 10 years ago

Wait, should I or shouldn't I be using the 608 bearings? I also have another question. What's the proper way to install the 8mm flexible couplings? Am I supposed to stop the threaded rod short of the spiral cut or is it suppose to touch the Z motor shaft?

by JRMN - General

Re: Z Motors and Threaded Rods - 10 years ago

Roger that. Take the 608 bearings out and as long as the threaded rods aren't long enough to touch the table, they should be fine. Oh and by the way, I ordered all my rods off eBay and they all came a littler longer than called for. I've had to cut a few already, just wondered if i needed to these is all. Thanks for the advice xclusive585.

Z Motors and Threaded Rods - 10 years ago

I am in the process of assembling the Z axis on a linear prusa with Z stabilizers. The instructions call for two 11 5/8" threaded rods that attach to the two Z motors. I was wondering if I can I use 12" threaded rods instead of 11 5/8“ Rods? I know the Z axis goes up and down, but I am not sure if it's supposed to be free once it raises or if it was of if it stayed in the 608 bearing of the 2

Re: X Carriage Belt Tensioner - 11 years ago

I finally got some free time to work on my 3D printer. I ended up ordering M3x35 bolts, but I just noticed that the belt is wider than the notch that the belt goes through. Is that what Wired1 was talking about when he said "make a cap for the end of the thread where it presses on the belt to prevent it punching through?" Do I widen it or do I bend the belt so that it fit as is?

Re: X Carriage Belt Tensioner - 11 years ago

Sorry for the late replay, but everyone in my house got sick over the weekend. I’ll probably just go to Lowes or Home Depot and see if I can get some longer screws. Once my printer is up and running I’ll probably look at some other options. Thanks for the advice guys, I appreciate the help.

X Carriage Belt Tensioner - 11 years ago

I am having issues installing the belt clamp on the left side of this . I am using a M3x22mm bolt as instructed, but it doesn't seem long enough. Does anyone have any good suggestions?

Re: Z Stabilizers - 11 years ago

Ok, so what I am hearing is that the Z stabilizers aren't really necessary and that I should use Nopheads couplings. Thanks guys.

by JRMN - General

Re: Z Stabilizers - 11 years ago

Thanks, so the flex couplings are better because they absorb the wiggly of your rods. So is the claim that using metal couplings gives you higher printer resolutions bogus?

Z Stabilizers - 11 years ago

I purchased my printed parts online late last year and I am just now putting my 3D pinter together. Anyway, I also purchased metal Z axis couplings, but the kit I have don’t have the Z stabilizers. I did a quick search and I came across this post about Z Stabilizers Siezing and I need to know if they are needed. Do I need Z stabilizers, what are the advantages of using them? thanks

Re: SAE Prusa X Axis Smooth Rods Length - 11 years ago

@Xiando, I guess I could have drilled out the back, however, I just cut the rods with my dremel. Looking at the rest of the instructions, I might have to cut the threaded rod that connects the 2 Z stabilizers as well. I'll cross that bridge when I get there. Thanks guys.

Re: SAE Prusa X Axis Smooth Rods Length - 11 years ago

I think they're 304 stainless steel. I also have a mini hacksaw, I might just try that because I am not sure if my cutting wheels are carbon fiber or not.

Re: SAE Prusa X Axis Smooth Rods Length - 11 years ago

That's what I thought, they are captive, I guess I'll have to cut them. Anyone has any good tips on cutting smooth rods? I do have a Dremel. What about the Z axis, I should be able to get by with the longer rods or will I have to cut them as well?

SAE Prusa X Axis Smooth Rods Length - 11 years ago

I am building a SAE Prusa and I am in the middle of assembling the X axis. I ordered all my rods precut from eBay and they all came a little longer than needed. I know using larger rods won't have any effect on the Y and Z axes, but I need to know if it will have any effect on the X axis. The X axis instructions call for 2 15 1/8" smooth rods and my rods are about 16". Before I go any furthe

Re: Motor Pulleys - 11 years ago

Thanks JazzyMT. One last question, do I have to add a flat to all the motors?

Re: Motor Pulleys - 11 years ago

Thanks good website, so is yours by the way. Just got home and the drill bit that fits inside of the pulley hole is 11/64-inch.

by JRMN - General

Re: Motor Pulleys - 11 years ago

Thanks for all the sugestions. I believe it's a SAE pulley with a slightly undersized hole because I have a SAE kit, but I'll have to meause the exact hole size when I get home. I think I might use my drill press stand that takes a power hand drill. Never used it before now though. lol

Re: Motor Pulleys - 11 years ago

Good advice thanks. What about drilling the pulley and advice there?

Re: Motor Pulleys - 11 years ago

Really, you mind sharing how it's done.? I have a dremel and would love to know how its done.

Re: Motor Pulleys - 11 years ago

I never measured the diameter of the pulleys, but the shaft is 5mm. How are you guys filing down the shafts?

by JRMN - General

Motor Pulleys - 11 years ago

My motor shafts are bigger than the pulley holes. Does anyone have any tips on drilling out the pulleys? I am worried that drilling out the pulleys by hand would lead to off-center pulley that would lead to uneven prints. I've also read that I should file the shafts flat. Is that correct?
