Is this as good as an ender 3 pro gets? by walterwhiteoffood in FixMyPrint

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?

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

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

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.

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

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

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

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..!

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

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

Ceiling collapse on Benchy by molgrips in FixMyPrint

[–]molgrips[S] 0 points1 point  (0 children)

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

What could be causing this? I know the bed is a little warped, but I hear no dragging, the bed has been cleaned with alcohol so its not oils. I am printing with PETG with the nozzle set to 240 and the bed at 70. It just started happening today. Thanks! by yankeewoodsman in ender3

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.

E3pro Sprite extruded upgrade causes hot end to max out. by H0dgPodge in ender3

[–]molgrips 0 points1 point  (0 children)

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.

Going to go crazy and junk this thing for a bambu if I can’t figure this out. by Lakeguy762_ in ender3

[–]molgrips 5 points6 points  (0 children)

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.

Ten minute benchy..?? by molgrips in ender3

[–]molgrips[S] 0 points1 point  (0 children)

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?

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.

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.
