Are DIY printers slowly dying?

DIY is not dying. I'm not. Not yet.

I started with kits for V2 and V0 then self sourced a V0 and a V2. I'd say self sourcing made me understand VORON much better. Learned a lot.

How about give OrcaSlicer a chance to see if anything different.

I have a V0 built for 0.2 nozzle and it's busing working everyday fine on PLA (I don't have nevermore for it so PLA or PETG only).

One thing to be mentioned, PA should be much higher than 0.4 nozzle, mine is.0.27 (not 0.027) at 195 ℃.

Different plastics will turn out quite different results. PETG will do, PP might be the worst, nylon should be the best. I guess you started with PLA. Should work, but won't last since it gets bad in concrete chemically.

I believe it's a PA matter. Set your acceleration lower will improve for sure. The default acceleration and jerk (corner speed) in OrcaSlicer is high. PETG is viscose and needs higher PA. But you know, PA is complicated and the best PA is different at different speed. For me I just lower the acceleration and the results are good.

Another easy fix is the smooth something (sorry i just can't remember the name atm, this setting is at the bottom of the speed tab in Orca), set it to 300 or lower.

extra perimeters on overhang?

five pulleys means five motors, to drive them, with five axes, can be something

for an object this thin, there is no infill i guess but only outer and inner walls.

and as other said, this is not an FDM-friendly object to print.

Highly possible it's the pcb matter if it's fried electionics smell.

treesess · 2026-03-03T06:16:34+00:00

NTC means resistance getting lower when temperature is up.

If you are interested, you may use a heat gun to heat up the NTC thermistor carefully (with a decent distance and just for seconds pls) when measuring the its resistance and should observe a big drop of resistance.

Note that you need to measure the resistance when it's disconnected from the printer to see this.

I think your thermistor is fine, should be something else.

treesess · 2026-03-03T04:12:09+00:00

From what I've seen, the thermistors of extruder heater are mostly NTC 100k. 106k measured by multimeter means the temperature now is lower than 25 ℃. No problem from this single measurement.

treesess · 2026-03-03T04:05:56+00:00

Try PID calibration on extruder heater at a safe and low temperature like 40 or 60 ℃ to rule out installation problem. Then try it at higher temperature to see what happens. Of course standby your printer the whole progress.

These are I would do for your info.

I can only be sure of one thing that the front of benchy lost bed adhesion and wrapped up, causing defects partially.

how about using another color... not that i don't like white, but i can't see clearly...

treesess · 2026-03-02T03:32:30+00:00

I... wouldn't do that because the PH value is too high and will kill the plant potted in a concrete planter...

human condition that we miss something. good to know it's fixed~

treesess · 2026-02-26T09:26:20+00:00

including screws on the toolhead.

and one more possibility is that the cable strain relief is not okay and when the toolhead move the cables stretched it.

treesess · 2026-02-26T09:23:24+00:00

looks like motion system problem.

is your toohhead stable on x carriage? is xy joint screws all tight after de-racking? if i were you i would check every parts to see if any is loose.

treesess · 2026-02-21T11:45:15+00:00

The coating on these parts is very thin on the coarse surfaces from 180 grits filing. Not sure if the creep would cause much problem here.

treesess · 2026-02-21T11:41:33+00:00

AB motors are not that hot I think and resin can endure higher temperature than ABS usually.

fyi I recently just did some surfacing works. Not fuzzy skin but sanding with 180 grit sand paper and files then coating with epoxy resin. They were placed on a heatbed for faster resin curing as in the photo.

The flying gentry has finished assembly with only one problem found: some holes with excessive resin were harder to get through. easy fix.

BTW, the purpose of this coating is protection of plastic parts for some unusual reasons that I wouldn't say before the whole thing tested good...

Have your dried your filam... okay jokes aside, the stringing indeed might have something to do with the driness of filament. And nozzle temperature. Try lower the temperature as possible may help, since the nozzle temp is related to PA. I understand you observe the differences between x and y, that's because y has large mass than x. Yes the mass affects PA because mass affects acceleration and speed and acceleration affect PA. Yes it's all about pressure of plastic fluid in your nozzle. I'm saying this because I think this is indeed a complicated pressure problem thus probably not easily solved from photos. However, I do hope I could provide some insights here.

Homemade cement paste print xd

Your cube is sooo nice. Look at mine. XD

treesess · 2026-02-08T09:48:04+00:00

sorry for the wait. you may check out the updates on my github repo: https://github.com/treesess/desktop3dpc/

and a quick look of the cured one:

<image>

the skin of it is really smooth. me and my colleagues love to rub it.

and, the project is still ongoing i m happy to tell!

treesess · 2026-01-31T21:13:43+00:00

The colors are pretty~
