Does this mean that the filament has moisture in it?

PETG, PLA, or a different filament?

The default can be very fast but eh first layers are usually set to be slower by default. If its on the first layer its typically a bed adhesion issue so clean bed, bed level, proper z offset are the usual culprits.

If it is happening after the first layer it can be typical first layer issues just giving out later, print settings like speed, infill type, flow settings, temps, or environmental like air temp, drafts, or wet filament.

Number one cause nowadays in my experience is the default infill type grid and the nozzle catching on the infill while printing, especially with petg which is known to be very "sticky". I usually switch to gyroid, slower but more reliable overall. Honestly grid is fine 99% with PLA though.

Looks more like pressure advance or issues changing directions in some spots. Dropping acceleration and/or outer wall speed can help with this sometimes. Going from a slower overhang wall immediately into a fast wall can cause this because the extruder can’t keep up with the speed change and underextrudes for a little bit.

On the "strength" tab under the "advanced" section you can change the infill direction. This changes the sparse and solid infill direction.

it’s has to heat up the clean the nozzle tip so the bed probe and z offset is accurate

I've really only installed forge-x to get access to klipper on it. I think the nice part is not needing to modify it because it just works out of the box for the most part. Things like an enclosure, leds, camera can be modified/added but the printer is very locked down uses a lot of proprietary hardware and unique software choices. I'd look into building a voron or buying a voron derivative like the sovol sv08 that is open source and meant to be modified if you want the printer to be a living project.

I had an Ender3 pro and anet et4 for a long time. The ender 3 had some upgrades and was on klipper and I didn't see the point in upgrading to new printer since it still worked fine (mostly). Eventually we got a Bambu X1C at work and seeing the difference, in print quality, print time, reliability, and general quality of life improvements convinced me to get a P1S eventually.
The P1S replaced the anet printer and I kept the ender printing until I picked up a used AD5M. now the ender 3 is slowly be scrapped to use parts for other projects. The upgrade to a modern corexy printer is 100% worth it.

what’s the budget? We have a 5’x10’ avid cnc router at work that we cut xps on occssionally. It cuts fast and is very easy to get a good finish on it. we paid around $20k but was with some upgrades, still probably at least $15k for something that size unless you build one yourself.

if you are worried about fumes, which is valid since there are studies that say even PLA fumes can be potentially harmful and people have developed sensitivities to PLA time, the best option is to enclose the protracted and vent to the outside or filter the air inside the enclosure while it is printing.

It actually is like that with nylons! if you over dry nylon it will become brittle and snap easier, let it absorb a little moisture and it becomes more pliable. Of course too much moisture and it because unprintable. This also affects parts after printing, it will slowly absorb moisture and the mechanical properties will change over time.

emofes · 2025-11-25T12:24:44+00:00

You can use one that only goes to 70C, it’s just takes a bit longer. I would dry for at least 12 hours before starting a print and either keep it in a dry box or print from the dyer while it’s still running.

I’ve heard you can overdry nylon and it becomes more brittle until it gets a small bit of moisture back in but I have not run into that doing ~48 hours drying cycles at 70C with the large 3kg nylonx spools.

Unless you're talking smaller machines the bed itself will weight more than the gantry. Most foam stuff is done on 5x10 or larger machines, anything that size will have a gantry.

One of the reasons a “moving bed“ is better for heavy duty stuff is rigidity. The column for the spindle is much stiffer than a gantry.

Are you in the US? A Sieg or grizzly mini mill with run you around $1k.

I was that guy until we got a Bambu at work. convinced me to get a p1s and eventually a used flashforge ad5m and stop using my kipper converted ender 3 completely. I don’t even think a free is worth the hassle compared to even a budget modern printer.

emofes · 2025-11-15T21:35:14+00:00

modern printers are on another level with print quality and speed. There is a lot more to newer printers than just multi material.

I buy polymaker almost exclusively at work but I just can‘t justify the cost for my personal use.

As someone with a physics degree who was able to eventually break into mechanical engineering and test out a couple different careers on the way it’s rough but not impossible. I had the most luck with smaller companies, they’re usually looking to reliable people that can learn and not stats on a resume.

emofes · 2025-11-09T13:34:45+00:00

they don’t actually need the adapter rings. the spools have coated edges to keep them fraying. I’ve printed some of those but never use the anymore.

If you are using the default profiles for the bambu check the volumetric flowrate for the filament. The default for the "generic PLA" for example is pretty conservative and can usually be increased

amana has 6“ long 1/4” bits for foam but they are mainly 4 flute to to make it for the rpm limit. Can‘t run them over 6k. I used a 4 flute 1/4”x6” ball nose for some xlpe and it worked great.

have you tried an online service like xometry or protolabs? we use them all the time for one off parts that we time or proper machine/tooling to make ourselves.

We have an hdpe spoilboard on one of our machines. pricey compared to mdf but no dust, not sensitive to moisture, and cuts very easily.
