I've been busy playing around, figured it was finally time.
Going through and calibrating the main filaments I print with. There are far too many to do all of them but I'll do the main ones. To clarify, I'm printing exclusively with the 0.6mm ObXidian Nozzle. I wanted maximum volumetric flow. This thing is a tool for me, not a toy, so I need it to work as productively as possible. Using Textured PEI (stock) plates for all but the K-Value calibration; for that one I'm using a 3rd party Smooth PEI plate since Bambu is OOS. I've been doing a full suite of calibrations, in this order: Temp Tower EM / Flow Ratio K-Value Max Flow Rate First one up, just because I have a ton to burn through, was Numakers PLA+. Temp tower came back 235ºC. Okay, a little warm, but Bambu seems to like warm. Next up, flow ratio. Unsurprising 0.98. K-Value, again, not surprising, 0.047. Then the max flow rate. Run 10-20. Blew through it no problem. Fine. 20-30. Passed again with flying colors. What the heck, this thing actually puts out what they say it does. 30-40. Again, printed a perfect ribbon, even up to 40mm³/s. Talk about impressive. At this point though I'm mad as I'm wondering if it will fail at all. Finally I say fine, 40-50. It throws an error on the layer in which it was printing at 47mm³/s. Nozzle Temp abnormal. Look down, it was at 210ºC. Looking at the ribbon, it looks like it started breaking down and having tearing at around 44mm³/s. I dialed it back 10%ish to 40mm³/s where I'll keep it. One filament down. About 20 to go. Also, I'm really, really liking Orca Slicer. |

Always curious what others experienced in tuning do. Watched a lot of the usual vids & everyone has their own opinions on this & that. Maybe share nozzle sizes as well.
Keep it coming. |

Thanks. I clarified my post...it's a 0.6mm ObXidian nozzle.

Where did you get the Obxidian hot end from?

Also, Bambu has all their plates back in stock as of this morning. I ordered 2 more of the smooth, textured & high temp PEI plates. |

I'm amazed at the performance of the 0.6. Numakers PLA+ prints perfect up to 40mm³/s. PETG I can do 35mm³/s. |

Once I get them I would greatly appreciate some guidance in getting the most speed out of some various filaments, especially ABS, as I have some I really want to knock time off of yet try to maintain print quality & layer adhesion. Right now I’m at max of 16cu/mm. |

What kind of speed gain/print quality are you getting from the .6?
I'm using the stock nozzles currently, and each print takes 8.5-9 hours |

The main part I print took 7:14 on a Prusa MK3S+ equipped with a Mosquito hotend. I was able to get about the same speed with a 0.4 stock hotend on the X1C. With similar wall thicknesses. An ObXidian 0.6 now prints it in 2:27. Nearly 3x faster. Just use the 0.6mm nozzle profile in the slicer and see. Should Slice no issue whether or not you actually have the nozzle on hand. |

View Quote Lol! simple is better, right - thanks for the tip! I may order one to try. i need these parts to look nice, but they aren't terribly intricate. It doesn't look like the time savings is going to help me in this case. |

Numakers has a cheat sheet for Bambu printers for their PLA+ and it looks like you can run 250C for a shiny finish. https://numakers.com/blogs/news/pla-plus-bambu-studio
My TZ 3.0 hotend came in for the Bambu P1S. Gonna be a bit before I try to install it though. I like the idea of easily changing the nozzle size and I bought some CHT clone nozzles for it. Figure I'll try this for a bit and see how it does. https://trianglelab.net/products/t2-30-upgrade-hot-end |

E3D Hotends came in. Can’t wait to start playing with them.
I see they are OOS at partsbuild. Arfcom strikes again. LOL Would recommend. Fast shipping. |

Well, the TZ 3.0 hotend didn't fare to well in this video.
I went ahead and ordered the E3D ObXidian for my P1S. West3D has them instock. LAYER ADHESION TESTED: Bambu Stock vs TZ 3.0 vs E3D HF ObXidian hotends (220C vs 240C) |

I hate to say it because fuck China but the bambu X1C is an impressive printer..
If they made one 2 or 3x the size for 3x the price, I'd buy it tomorrow. Also...if they could hit 400c or even 350c on the hot end that would open up a whole world of proper engineering grade materials. That thing would run 24/7 in my shop. |

Ah screw it. Picked up 0.6mm E3D so I can start pushing this thing. Coming from an Ender, the stock speeds on the X1C were already blazing fast. But now I'm wanting to cut the times even more.

Picked up some Bambu PETG-CF this afternoon. Dried it out. Looking for a print to use on.....

Finally got around to installing a .6 E3D for testing.
After playing with it for most of the day I settled on 30cu/mm along with speed settings to match the new flow rate. Sliced one of my longer prints that was 11h 45min with the old settings. New print time now is 7h 35min. Shows some very minute stringing over areas where the gap is about 1”. Looks aren’t critical with these parts, but strength is. Seems to be as structurally sound as before, which is important because these are shims that literally get pounded with sledge hammers. I’ll know for sure once they get field tested. So far I’m pretty happy. |

I tested Bambu PETG basic with the E3D Obxidian 0.4 and I started getting artifacts around 29 cubic mm/s, but no gapping in the extrusion till about 35ish. I set max at 25. However, I may need to run this test at a higher extrusion temperature than 255C. This printer seems to like it hotter at around 260.
I tested Numakers PLA+ to 30 with the E3D Obxidian 0.4, but that maxed out the flow test. I haven't tested higher yet. I had some old Jayo PLA+ left to use up printing a poop chute for the Bambu P1S on my QIDI Xplus3 0.4 CHT clone and when it ran out I put the Numakers PLA+ in and at the same flow of 25 the Jayo showed missed extrusions while the Numakers PLA+ was perfect and had no issues at that high of flow rate. |

I stumbled across the set of files from eSun for their filaments for different printers. (Its on their download site)
My neighbor got his X1C setup with PLA, ABS, ASA, and ePA-CF. They all needed some tweaking and he had to run a few calibration steps for each type. The one for ePA-CF was really fucky... But drying the shit out of his spools made a yuge difference. |
