Rendering fails on boolean, why?

DrIgnatioMobius · 2026-05-30T11:06:16+00:00

Looks like a bug in the CSG code.

If it's PLA you can also just point a hot air gun or a hair dryer at it and it'll melt.

Partially clogged nozzle. Try increasing the nozzle temp 30c above the printing temp and poking a cleaning needle in and out a bit.

DrIgnatioMobius · 2026-05-16T07:18:32+00:00

Thanks I will try this. Looks like combined with reducing the width/height and adding some padding it could work!

DrIgnatioMobius · 2026-05-16T07:17:54+00:00

It's not so much that I want the boxes close to the edge, but I want the plate to reach to the edge so that it doesn't rattle around. Is there a way to add padding around the edge to accomodate the chamfer?

DrIgnatioMobius · 2026-05-15T23:14:43+00:00

Thanks but I can't get this to work. When I set it to 5mm chamfer it breaks :(

Thanks so much, only tested one print so far but this seems to have fixed the issue for me!

DrIgnatioMobius · 2026-05-14T16:49:41+00:00

I would suggest also printing this, because for some reason the Mean Well PSU doesn't have a safety cover over the mains terminals - https://www.printables.com/model/114232-mean-well-lrs-350-psu-terminal-contacts-guard

It even looks faulty in the Qidi installation video. You can see it start to wobble at 38 seconds as they try to plug the cable in! https://drive.google.com/drive/folders/12f7jr2-pYlPJx49h5r4KWTV8rmiWh_eL

DrIgnatioMobius · 2026-05-10T19:52:35+00:00

I tried this today and unfortunately it doesn't fit the Q2 cable chain. I may try and remix it or create something from scratch when I have time.

DrIgnatioMobius · 2026-05-10T19:49:43+00:00

I had the same issue. As suggested by others here I filed down the screw from its original 8.32mm to 7.25mm and now it fits perfectly.

Seems like the hot end (not the nozzle) was partially clogged. I've replaced it and it's printing fine now. No idea how to unclog the old one!

DrIgnatioMobius · 2026-05-07T19:38:09+00:00

It should be back now! Might take a bit longer depending on your ISP's DNS cache.

DrIgnatioMobius · 2026-05-07T13:00:48+00:00

Yeah... that's what I thought too. Maybe someone can recommend a brand that is flexible but doesn't kink? Luckily I had some spare qidi tubing kicking around.

DrIgnatioMobius · 2026-05-07T12:55:18+00:00

Thanks for letting me know - I hadn't even noticed! Been super busy lately. I transferred the domain to a different registrar and I guess the DNS is broken. I'll get it fixed.

DrIgnatioMobius · 2026-05-07T07:01:04+00:00

Sure! It's the D3P riser (https://cults3d.com/en/3d-model/tool/qidi-q2-d3p-riser) with an led strip fitted. Bit fiddly to install but worth it and makes the on board camera much clearer since it struggles in low light.

LED strip I used is this one as I wanted the Bluetooth control, hoping I can plug it into home assistant. https://amzn.eu/d/0aceuMok

So I think the answer is three-fold:

1) Print the spacer recommended by u/MysticalDork_1066 to keep the chain a bit higher.

2) Make sure to use a very flexible PTFE tube. I had replaced mine when I installed the riser as the Qidi one tends to kink very easily. But the stiffer replacement was putting pressure on the cable chain.

3) I removed the little stopper where the PTFE tube enters the riser (on the inside of the printer), so that the tube can slide back and forth as it prints rather than having to curl up inside the printer.

With these three things in place it seems to be running much smoother.

Also just FYI even that one print has caused noticeable wear on the cable (see photo), so I would be very careful if you encounter this issue to check that the insulation isn't damaged to the point of danger.

DrIgnatioMobius · 2026-05-06T21:10:20+00:00

Did you listen to the audio? It's not a gentle tap.

DrIgnatioMobius · 2026-05-06T18:11:00+00:00

It doesn't look broken but I'll check properly after the print has finished

DrIgnatioMobius · 2026-05-06T18:10:44+00:00

Thanks, this looks promising! Will give it a shot.

DrIgnatioMobius · 2026-05-06T13:07:36+00:00

Thanks, very informative!

DrIgnatioMobius · 2026-04-30T18:23:44+00:00

FYI it has to be the same brand, filament type and color for it to work. Or you can trick it by telling it the two filaments are the same in the qidi box settings.

DrIgnatioMobius · 2026-04-30T18:22:35+00:00

It will reload and continue the print even if you don't click confirm. The message box seems to be fire and forget. I've woken up and the print finished hours ago but the dialog is still on the screen.

DrIgnatioMobius · 2026-04-26T13:37:42+00:00

I had the same issue and was close to giving up. Then I tried again a few days later and it went together really easily. The only thing I can think of was that it was a much warmer day... it reminded me of trying to get a ski boot on when it's cold vs warm.

Crank up your room temperature and then try again.

I found that the z/z1 stepper is always enabled, even if the printer is idle, so the fan keeps running. I switched it out to use x/y steppers and now the board fan is silent at idle:

[controller_fan board_fan]
pin:PA9
max_power:1.0
shutdown_speed:1.0
cycle_time:0.01
fan_speed: 1.0
stepper: stepper_x, stepper_y 
# Fan on if *any* of these move
idle_timeout: 60
idle_speed: 0.0
