I printed a straight up 1" cube flat on the bed and it is flawless.
I didn't want to do that on the adapter remover because the threads would be too weak. I should try 45 degree with a fancy support

I'm not sure if the Creality slicer allows it but if you can use adaptive layer height it may help smooth the transition from layer to layer when printing on an angle. It works well on printing a sphere where the change in circumference makes for a large change in where the edge of the layer starts. Just spitballing.

+1 for the 45 degree print. Should solve all the problems and maintain thread strength.
It does works the same as others. I don’t think there is much difference between slicers these days. For threads you can print at angles also increase wall lines.
That's a really good question I would not have thought about it that way. I have printed up to 0.8 and standard size on my belt printer was 0.6. Fell like I might have to look in to getting a dual head or multi head printer one of these days. Awesome watching guys print without purging an entire bin with each color swap.

Not available on the Bambu multi head printers. My H2D can't and none of the other Bambus can either.
They say it is a massively complicated software problem.
But Prusa and Snapmaker I think have figured it out.
There are ways to spoof the Bambu multihead printers by changing the nozzle size partway through the print or mislabeleing the size so the printer thinks it is a .4 when it's really a .6 or ,8..
Seems like a lot of futzing around, honestly.

Where do you set your flushing volumes? I turned mine down as far as I could, the system complains but I have never seen any ill effects from it in fact most times I wouldn't care if it feed the next color without any flushing.
I have mine set at the default volume. I have used the guide from creality. It is not the best. Seems to purge a lot for my taste

I received some emails about this one, love the efficiency of filament use but not sure of the quality and durability.
Looks like a bambu A1 and no waste seems to be relying on purging to infill - I think some slicers already do this. I've meaning to try that - anyone try purging colour change to infill?
I have the H2C, my preferred engineering filament is PET-GF - not PETG-GF. Reinforced PET is a very tough and durable material, well suited for light duty parts.
Large threaded objects print quite accurately with the 0.4mm nozzle.
The smallest I have tried is an M22x1.5. While it printed neatly, it was about 15 thou oversize so I needed to run it through a die.
For other small threaded parts, the threaded portion is not printed as a thread, but a circular section slightly larger than the major diameter of the thread, then use the die or lathe to finish.
Larger threads such as 1-1/2x8 will require support for the overhang. But again some thread chasing is needed. Print orientation affects the fit and strength too.
PETG-HF vs. PET-GF. The PETG is far too soft to carry any real load, and the PET-GF doesn't deform nearly as much.
These soft plastics always produce an oversize thread after passing through the die, because the material deforms under the cutting pressure, then relaxes. The resulting threaadform is slightly oversize and is likely to be a tight fit. The harder filaments do not deform (as much) and the resulting thread is a reasonable fit.
When printing exotic filaments, pay attention to the support material and the bed adhesive which must be compatible with all of the main object materials. Not only for molecular compatability, but bed temperature, and chamber temperature. Many useful filaments do not seem to have a corresponding support material within my budget, so some experimenting is necessary. PET-GF is horrible stuff to support properly due to the high print and chamber temperature which limits the support material to nylons and polycarbonate. Other support materials are soft at these elevated temperatures and the usual bed adhesives degrade above 60C.
The H2C does a very good job of reducing purge filament waste - instead of squirting expensive filament down the poop chute, it creates a large prime tower which catches all the dribbles so that the print nozzle is clear, charged and ready to print. Each filament has its own nozzle, primed and ready to go without further purging.
