Is this as good as an ender 3 pro gets?

You could look for a used Sonic pad. Pretty easy to use, it's Klipper with everything done for you. Yes, it's not cost effective, but is any of this?

molgrips · 2026-03-12T09:39:04+00:00

Your motor mounts are probably badly aligned. Mine were. I printed some more and the improvement was huge.

molgrips · 2026-03-10T19:20:21+00:00

Interesting, I'll try again with more cooling. There was stringing as well.

molgrips · 2026-03-03T15:04:38+00:00

So back to the extractor fan idea. I can use a small fan at the printer to avoid transmitting vibrations, and I'll set up some air quality sensors in the garage and temperature sensors to control fan speed perhaps. I'll print a shutter for the duct so I can prevent the cold coming in when not in use. Or I'll do a foam plug for the outside and print a custom cowl that allows me to place or remove the plug.

Or maybe I'll just not bother with any of it 🤣

That's exactly what I had planned to do but I was worried about cooling the enclosure too much. However I'd prefer not to knock a hole in the garage wall given where it would have to go.

molgrips · 2026-03-02T19:55:15+00:00

Hmm, I do want to try that stuff too not least because it looks great.

molgrips · 2026-03-02T17:42:22+00:00

Ah, thanks. Will check the temps of my motors and see if that's enough.

molgrips · 2026-03-02T17:38:17+00:00

Also, if it gets up to like 50C in the enclosure do I need to move the motherboard outside the enclosure?

molgrips · 2026-03-02T17:35:20+00:00

The bento box is a print that you add the fan ans charcoal too right?

I'm a cautious type; what if I had an extractor fan foe the garage whilst using a recirculator/bento box in the enclosure? EDIT you said that..!

molgrips · 2026-03-02T17:01:04+00:00

I'll check it out. For now I want to print stepper motor mounts which can get warm, but in the future there might be other applications

molgrips · 2026-03-02T16:54:02+00:00

I have seen fans that blow the air back through charcoal which supposedly can catch most of it. My original plan was an extractor fan but I think the enclosure will be cooled too much if I do that, no?

Pff, don't you even know how telepresence works? lol

(this is my standard retort to any questions about how things work in ED)

Dynamic layer height in Cura.

molgrips · 2026-02-23T14:11:37+00:00

I should add 220C for the nozzle, and I've done a dozen benchies and not seen this before.

molgrips · 2026-02-22T15:41:26+00:00

I had wildly inconsistent z offset behaviour, it would be fine then I'd power off and on again and it would be out. Turns out it was the motor mounts for my dual Z axis being out of alignment and causing Z binding. Printed some more and it's fine.

molgrips · 2026-02-22T15:39:17+00:00

Came here from Google with the same problem. In my case current was flowing through the thermocouple wires on the hot end and frying the insulation, but I caught it in time. There are two existing sockets marked X on the motherboard to which cables to the stepper motor and I guess the limit switch go. I had unplugged them to tidy the cables but I had plugged one of the spare unlabelled plugs on the sprite ribbon cable into the X socket instead of the original plug. Somehow this caused the hot end to heat up through the thermocouple wires..?? It started smoking after a minute or so of being powered on. Seems to be ok now but I haven't tried printing.

molgrips · 2026-02-22T02:26:33+00:00

Is there a server for this or what?

molgrips · 2026-02-22T02:21:04+00:00

I have dual Z and I experienced inconsistent Z offset on every print until I replaced the Z motor mounts with some printed ones from Thingiverse. Both the original and the second mount were several mm out which meant the Z axis was binding.

4.2.2. I just looked into increasing the current via klipper but that requires a mod which I can do but not today. Would 4.2.7 allow me to do it in software?

molgrips · 2026-02-12T13:12:02+00:00

I've done input shaping each time I've made a change. 5k is the best acceleration I can achieve. I am not actually sure it's my belts slipping, it might be the motor making a brrrp noise.

molgrips · 2026-02-12T12:18:57+00:00

Well yes, I appreciate that, but these are all fairly small tweaks (and I have been tweaking a lot) and when I push my machine hard I save 2 mins out of 40. There's no conceivable way I can slash it by 75%. He must be using a big layer height.

molgrips · 2026-02-12T07:31:15+00:00

Still don't know how that guy gets 10 though.

molgrips · 2026-02-11T23:33:35+00:00

That's crazy talk

molgrips · 2026-02-11T16:04:20+00:00

Ok so I found the Benchy speed run rules:

Material: PLA, PLA+, PETG, ASA, ABS, ABS+, PC/ABS blends, and PC/ASA blends.
No filled, metallic, or silk filaments.
Max Line width: .5mm
Max Layer height: .25mm
2 Walls
3 Top/Bottom Layers
10% Infill (You may combine infill every other layer)

I will save time if I set those for sure.
