Print FAST with an Ender 3 pro

Thank you for watching. Please consider liking, commenting, and subscribing.

The Creality Spider Hotend is a simple upgrade for an Ender 3 pro and is very useful for printing at high speed. When stock, an Ender 3 pro can print at speeds up to 50 mm/s but with this mod I was able to achieve speeds up to 250 mm/s. The hotend only cost $39.99 from Micro Center and is a bit more expensive on Amazon at the time of writing this. The mod can cut the print speed down by about half.

As many of the comments read, the printing speed in the video was not 250mm/s. It was still double the speed of before and cut the time required to print in half. Sorry for the confusion. The firmware limits the acceleration, which limits the overall speed. To actually achieve these speeds you must configure a firmware to allow these speeds.

That’s not 250mm/s. I’ve printed at 120mm/s in the past and it went much faster than that.

You have to reduce your minimum layer time in your slicer software! In Cura it’s set to 10 seconds by default.

The stock hotend is not at all speed limiting on Ender 3. It can go at least 15 mm³/s (around 180 mm/s linear motion speed) and nearly twice that with a CHT nozzle. As others have said you're not reaching anywhere near that speed, probably because of acceleration and min layer time settings, but you almost surely won't be able to even with those settings changed because the stock extruder, which is the bottleneck on this printer, doesn't have enough grip or torque.

Your board is stalling out and not hitting 250mm. When you see the toolhead stop and sit there, the board is overwhelmed and processing gcode. Marlin firmware on the board isn't going to do it. (even on a 32 bit board) It cannot keep up. The motors are moving at high speeds but the board and firmware cannot provide gcode fast enough. Until you upgrade to Klipper, you are slamming on the gas then slamming on the brakes. (both bad speed and bad quality at the same time)

If you want to print fast, you need to run Klipper. (which requires an additional 64 bit processor such as a raspberry pi or at least a cheap Linux computer) Your main board is flashed with Klipper firmware that primarily controls the motor and the raspberry pi will keep it fed with gcode. Until you upgrade to Kilpper you need to lower your speed until that stalling behavior never happens. (quality will improve, especially little zits on the outer walls) That it the fastest that you can print with your board. (nowhere near 250mm btw)

Dear Lord, fix your audio. You are beyond over modulated

[Juhsga]

Let us know if you dial it in more and get rid of the jerkiness and have smoother prints. Try playing with jerk and acceleration settings more and tell us how it turns out. I may do the same if you get ideal results.

[eclypsed]

Apparently your definition of great and perfect vary a bit from most others lol, looks like you are printing with cake frosting. You need to run input shaping, pressure advance and set your timing if you are running at even 60mm Id be surprised. My tuned E2 pro runs easily twice the speed of this

Sorry for the bad audio quality. When exporting this video from the editing software something got messed up.

I'd like to see how these upgrades (particularly the new hotend shroud) help with overhangs on sub 100mm/s prints.

[Tsipli]

bro i literaly have a 3 euro mic and conect it to AN old phone and sound crystal clear. please take one it will help you

[trynez]

That is not 200mm/s, thats maybe 80mm/s max you're reaching. try and look into increasing your acceleration from the stock ender 3 500mm/s to 4000mm/s and change slicer acceleration settings for perimeters, infill etc.

[restipalupi]

what kind of motor did you use to support the extruder ?

[yobtnirpD]

I'm printing 75mmps on a stock ender 3 pro

[scott]

I have yet to see 1 real benefit of this nozzle over a Swiss hot end. No one addresses the firmware update to accommodate the higher speed or temp limits.

Hi Dear, Do you have any plans to do a Review for Creality Spider 4.0 Ceramics Hotend? We can provide the sample.

[DevarshiAggarwal]

In your description you say that if we are not careful modification can cause serious injury, okay. But death?

[zk_]

I think you need a different microphone.

[alexplays]

My base ender 3 Neo prints way better than that with higher speeds

[MicahFranco]

is it ok if you scream on that mic lol

[hektor]

That's not running 250 no way. Especially with single gear stock extruder buddy. Your max speed there is like 70 to 80 at best. You haven't set up your accelerations, jerks, proper perimeter settings to even talk going at 100mm. Stock ender 3 even with that Hotend you installed by creality that you will soon throw in the bin because it's complete rubbish deceased with constant clogs, stock enders top out around 110 to 120mm. You extruder will fail. You'll clog. Your motion steppers won't keep up and skip causing layer shifts.
Do some homework before trying to teach others about something you obviously know nothing about. Good luck
