Whatcha Printing?

[RetroThutmose]

Think I got her dialed back in good enough.

edit: print came out great. i was worried i didn't use a brim to get better adhesion as i noticed it started to warp a little towards the end of the print. it literally fell off the build plate when i gently touched it. smh. came out great except for a tiny spot where it bridges a large span. should be fine for use tho.

What were you using the nylon for? The jet pump?

M'yeah, the pump, turn fins, roll cage, etc. I learned it is not what I want to use. I was also printing some parts for surface rc stuff

 

[TeknoJ]

Thinks are still moving along. Mostly just have the jet pump parts to print and I need to get some more hardware. Idk when Lowe's changed their hardware section but it sure sucks now. Home Depot is a tiny bit better.

Aliexpress had all the hardware for cheap, way cheaper than any hardware store or amazon.
It looks good, I like the blue you have going there. Were color spectrum opposites, I have orange you have blue.

is there a kit or just ordering piecemeal?

 

[RetroThutmose]

upgraded my printer with silicone spacers instead of springs and I'm noticing much better accuracy in circles on the z plane. usually they get kind of squished.

Nope, you piece it out based off the gentleman’s hardware list. I will have about twice the screws needed too.
Amazon was going to be those packs of M-whatever through whatever and mostly stuff I wouldn’t need since it is stainless. Between Amazon and Ali- it’s the same product. Amazon just charges twice as much.

What is a good oil to lube my x and y axis. I am running real low on the Bambu stuff that came with my printer. I have been using super lube to grease the z axis; I was thinking a clear oil would be just fine.

You don't want to use anything that will attract dust.

I was considering switching to a dry lube spray since I have some here. Thanks, this is exactly the answer I needed.

I used to use vaseline on the Z axis screw until I looked back there one day and found half my cat clinging to it

I can use the dry lube on those worm gear rods too? The grease makes a mess.

 

[TeknoJ]

One is overture nylon, one is sunlu petg
Both are almost flawless prints. The petg gets some fuzzies which is better than stringiness I suppose. This print has a couple spots that might be potential layer separation.

Yeah. I use it on mine. But if I'm honest, I don't lube it more than once, maybe twice a year. I can't even remember the lsst time I lubed mine. And one printer is over 8 years old and the Z axis measurements on parts is dead nuts.

@WickedFog don’t be shy, I need you to pick apart that print.
From here I don’t know how to tune out those minor flaws

These are Y axis?

If so, look for play there. Is yours belt driven? If so, tighten this belt slightly and print a test cube with sharp corners. The stringing on that PETG is minimsl, but you could try upping your coast setting by .5mm at a time and see if that helps. When you start seeing gaps at the start and stop points, you've gone to far. To test, it's best to set the start and stop points to a set location. Like XY zero. But that is not bad stringing for PETG.

 

[WickedFog]

And these dots are likely your actual start and stop points...

That shows your retraction setting is a tad too low. Add another 1 or 2 millimeter to your retraction. That will also do kinda the same thing as coast though. So go +1mm more on retraction and +.5mm on coast and see what you get on a test cube, after checking your XY slop/tension.

One way to check that is with a dial indicator. Set it on the build plate edge facing the direction of travel. Run the axis to zero the indicator, then move it away from the indicator one full revolution of the indicator and see how far it's off.

 

[WickedFog]

Actually, I see those pics are of both axis. Check both X and Y for play. When your printer is traveling and changes direction, it is coasting too far.

Bots coming together, need to order more hardware. Depleted all my local spots

Looking awesome!

What happened here?

@TeknoJ - you check your XY axis yet? I am curious what you'll find.
