Gents, could someone give a quick explanation on nozzles? I see the ender 3 has out the box 0.4mm, and DIY has 0.3, 0.25 respectably at a various ranges for sale. My current understanding is that the nozzle could be deemed similar to the resolution aspect of a print? My question is, when and where to use and secondly, doesn't the smaller apertute impact the flow rate? Would that not need to be adjusted/set?

Also with the price range in nozzles from R20odd to R600, the main differance I see is coatings and durability, does this genuinely make such a huge differance? The jumps are from like R20 to R200 to R600?

Well I'm a lady but I'll answer anyway.

We have a printer that's permanently got a 0.25 nozzle on it running PLA. For smaller and especially thin-walled parts it's really nice, and one of the biggest advantages is that support structure breaks away like a dream. Even little cavities where a 0.4 would dump down some tricky to remove support, the 0.25 stuff just pops out. And layer height: Using a 0.4 nozzle at 0.1 or 0.08 layer height doesn't make a huge difference, the 0.25 at 0.06 or 0.08 layer height is noticeably different (better) to a 0.4 nozzle at 0.06 or 0.08. Never had issues printing PLA, gets quite tricky printing other materials. Suppose some of this might just be printer specific tho.

If you've got a need for more functional parts with finer details it's worth experimenting with, especially if you need the bit of flex/give that an FDM printed part gives.

Just some updates on my VzBot. Its been printing for a week and a bit. I used a pi zero with klipper but its barely keeping up and can't calibrate input shaping with the adxl345 so needs a proper pi. I ordered one from RS but they changed delivery date to december so I'm trying to cancel that one and ordered one from pishop. Then I still need to order all the panels for the enclosure/lid and a few other finishing items.

What are you building?

I picked up a base Ender 3 for cheap a few weeks back, still in customs but getting the little upgrades together so aluminum extruder, springs, BL Touch and this is the upgraded board ( SKR 3 E v2.0 ) for quieter running, some steppers to do lighting etc, dampners , capricorn tubing , glass bed and some nozzles ( .3 and .2 ).

Two boxes of filament are black PLA, red PETG and I have white PETG incoming with the main shipment as well. Hopefully everything gets here by the long weekend. Also that it all doesn't get here TOO much before then or I won't get any work done,

Sounds like fun. Send some more pics when you get the rest.

Any idea where I can find Translucent pla? Preferably white, I see Rs have bit a bit pricy

Nice.

Dying here now, everything has arrived but the printer, which has cleared customs. Installed CURA last night and played with a few models.

Arb question, I assume one needs to adjust extrusion speed when decreasing nozzle size? Any rule of thumb? ie: 0.4 -> 0.3 , decrease speed by x

 

[Kosmik]

I didn't adjust for extrusion speed. By speed, do you mean printing speed? like 50mm/s?

In cure, selecting a different nozzle size will adjust everything you should require, but to defaults. The only thing you might want to do adjust your flow percentages to get some form of dimensional accuracy.

Printing speed is how fast the head moves? Or is it how fast the filament is extruded into the nozzle? The second is what I meant as I would assume being a smaller aperture, keeping the same speed would cause blobbing etc?

What kind of parts do you want to print?

They are great there, they dont play around, proper machines

Printing speed affects the speed of the nozzle yes not the rate of extrusion. I might be wrong here but the nozzle size will only affect line width which you set in Cura. The actual amount that should be extruded is calculated (by Cura) based on line width, line height, flow rate, and probably a bunch of other things as well. The printer firmware does another conversion of that required extrusion based on the e-step multiplier. Basically, there are a bunch of things that affect how much filament is extruded.

As mentioned you should calibrate for the smaller nozzle which would mean calibrating the correct flow rate and e-steps for the new nozzle but that is something you should do any time you change any part from the extruder to the nozzle in any case.

Pretty decent guide to calibrating your printer. https://teachingtechyt.github.io/calibration.html#intro

Amazing how much distance fresh firmware makes. Stick on the sk3 refused to auto home or recognize the stops, first attempt at patched firmeare failed, shifted to stable release and recommended configs, all good. Now to print the bl mount and install.

I seem to be having an issue with filament reels. So I finished the temp filament that can with the printer and loaded up a sunlu pla black to do some mods. Pick having a similar issue as my weed water, every now and then the filament sits hot roll of because it's tracked on the spool. Do you guys roll portions of spool? Or just use the 1kg roll? Is this a cookbook problem or do I just have a bad spool?

Its hard to decipher that but if you are asking if a new roll of filament tends to unroll itself then yes its a pain with some of them being worse than others. A few prints in it should be fine.

Not just unroll, there's s twist in the winding so after a couple metres or less, it snags as the winding crosses
