Best 45 bucks I ever spent on this printer. Not only is it whisper quiet, it runs much smoother now with less vibration and shudder. It prints noticeably faster as well. Easy drop in installation. While there is a lack of instructions in the package, anyone who is techy will be able to read the silk screen on the board and figure out what goes where with little fuss. It came with the firmware loaded on the board so it was a drop in for my Ender 3. I did swap out the firmware which is super easy to do, so that it would support my ABL probe. Just buy this board and you wont be sorry you did.

Just want to update this back to 5 stars. Gulfcoast contacted me immediately explaining the stock was older hence lower price but could be used for spares etc. and will refund my cost in full.
This was in my mind a fantastic example of customer service. Of course the price is not going to bankrupt them but taking care of their customers that quickly is priceless making them a top class business to deal with. 11/10 for effort.

No assembly instructions. Strange set of screws, 4 completely obscure. Only 1 M3 suitably long for connection to motor so therefore 3 are missing.
No decent way to affix the spring. Moving lever filament hole not aligned with bearing needing a spacer.
On the whole a poor extruder, only $4.99 but I recommend another version.

Bought to replace the hotend on my Ender 3. Install was straightforward and it has been working great!

The support for this product has been fantastic! I bought this because I had been having some flow issues, and this helped, but didn't solve it all the way. The support team helped diagnose, and we realized it has nothing to do with the hotend (needed to replace the terrible plastic extruder, it had cracked). Even though that has nothing to do with what I bought, they made sure to help me get everything set up, and now all is running perfectly!

I was having a lot of leveling issues with my original Ender 3 Pro bed. I ran Bed Level Visualizer, on my original bed with a BLTouch and found that the bed was severely dipped in the middle and just plain horrible. So I bit the bullet and decided to upgrade my bed with this kit along with the silicone heating element. What a night and day difference! I added a Wham Bam Flex kit as well, once I performed the Bed Level Visualizer in Octoprint using an BLTouch, this was a huge improvement! Bed was flatter and hardly any dips and just had to use a small tiny strip of a sticky note to get the whole bed within the same range, that's it. I used stiff bed mounts, so this helped as well to get things stored and keep the same mesh for every print. I also paired this with the three point leveling carriage but didn't use the three points, instead I'm using 4 points. Only reason why I used the Gulf coast carriage is due to being lighter than the stock carriage.

Now all my prints stick and no more leveling issues! My temps are much more consistent using PID auto-tune. Just make sure to change your Marline code to use the correct thermal device!

Thanks for saving my printer! Very pleased!

I've been using this for over a year and it works great. I don't know the correct M308 parameters for the thermister so I've been using

M308 S0 P"bedtemp" Y"thermistor" T100000 B4725 C7.06e-8
T value of 100,000 is thermister resistance at 25C
B is Beta value of the thermister
C is Steinhart-Hart C coefficient, default 0

If you have this information, I'd love it. No matter, the product works great.

Let me state first that I haven't used this part yet but I intend to. My initial observation is that the brass hex used to screw the thermister in place is larger than necessary thereby sinking heat away from the heat block and exposing the sinked heat to cooling air from the fan. I would reduce the hex height by at least 50%. I would also make it square rather than hex.

Not sure where you got the data sheet, but the EPCOS data sheet at Farnell shows 300°C

Needed to replace the PFTE lined stock hotends for my ender 3 pros, so I decided to give these a shot based off how pleased I was with the LED kits. I didn't quite know what to expect, but once I got these dialed in, it was smooth sailing. Glad I made this purchase!

EPCOS B57560G104F Datasheet states this thermistor's maximum working temperature is 200c. In the description here you can clearly see that the stated working temperature is 300c. Clearly this is false advertising as defined by law.

I'll be requesting a refund, or back charging. Whichever is more effective.

Don't lie about your products. Know what you're selling if this is an honest mistake, but I don't think it is.

20 minutes to install and no problems with bed leveling since, in fact today is my 8th day of almost continuous printing without spending any time leveling the bed. Before installing this plate I was spending 1 to 2 hours trying to level the bed with sporadic success. I now love my Ender 3 but, unfortunately I'm now bald. (just kidding) If your on thence about buying this just do it you won't be sorry.

Bought this to replace the glass bead thermistor, for the bead resistors kept breaking. Put this in, did a PID tune, and the heat curve was much smoother than any other glass bead thermistor. I highly recommend this as an upgrade.

I've had my Ender 3 for about 3 years and this is by far the best upgrade I've done because it finally allows me to move beyond PLA.
I happened to find this product while searching for something else for my printer and I bought it on impulse along with a roll of PETG.
I should have done this years ago! It's opened up a whole new world.
This is a good, cheap, and easy upgrade and I recommend it highly for anyone owning an Ender 3.

The light was pretty good before, but the recent design changes really make this an amazing product. Debating whether or not to replace the other one I have with a newer one.

Easy drop in replacement for my Ender 3 pro. Takes a little effort to switch the wires since the manufacturer used hot glue on the connections, but worked straight out of the box.
They are not kidding about the stepper motors being "silent". Night and day difference in the amount of sound.
Looking forward to taking advantage of the features of this board.
Great product
