I am trying to plug this board into a BigTreeTech SKR E3 Mini... and failing so far. And now I'm finding it may not be compatible with the board at all (which I doubt) This screen is shipped with no instructions. They are able to be found on the website, but it's quite the research project. So far this is what I've gathered. By default the screen operates in 12864 compatibility mode which... well I've never gotten to work. To switch modes (to serial) press and hold in the wheel until the menu appears. You will almost definitely need to update the firmware to make this board work. To do this visit their github site and download a firmware image. To install this, you'll need either a full SD card or a microSD card with an adapter. Wiring for this board is difficult to figure out. Make sure you use the serial connection rather than the original 10 pin IDC ribbon cable. This means you'll want to use the black cable. Connection for the black cable is a pain to find. You'll find the PCB layouts on BigTreeTech's github. If you're using the E3 mini, the wiring for the TFT serial connector is found on the bottom of the circuit board. The normal documentation for the TFT24 covers how to wire the LCD. Once the screen boots, it will complain that there is no printer attached. I imagine this is because my Marlin firmware is not compiled to support the serial port on the E3 Mini. If this works, I'll attempt to update my review

I haven't tested this hotend yet, but I have a Microswiss already on another printer and while the Microswiss is definitely of a higher build quality, this one has a MAJOR advantage over the Microswiss. It has screws from the heat block into the heat sink. This means that when you want to remove the nozzle (which will be necessary when printing carbon fiber) in order to clean it... or you simply want to change nozzles... this is a far better design. I will install this on my CR-10s and if it works well, I'll move it to my Ender 5 Pro instead.

These are great motors and I'll use them for lightweight direct 3d printer extruders. These DO NOT deliver enough torque to use for pushing difficult materials with the BMG extruder clones. For that, I'm using the 40mm deep Creality motors after trying and failing with this one. I would recommend this purchase to anyone who will not be printing with abrasive materials. I have tried using it with BASF PAHT CF15 which is a high temperature nylon/carbon fiber filament along with a Microswiss 0.8mm nozzle. This material should have pushed through easily. It really did not. This motor just choked.

Dupont connectors are precisely the wrong kind of connector for this device. Since the device will be moving A LOT, Dupont connectors will regularly fall apart. The solution is either replace the connectors or hot glue the connectors together. I will cut the delivered connectors off and replace them with JST type connectors instead.

I have not installed this produce yet, but it's clear from first site it's one of the better quality generic products delivered by Banggood for 3D printers. The choice in location for the JST SM connector installed inline with the heating element is perfect. It's not so close to be a hazard and it's not too far to make it inconvenient. I have crimped JST SM connectors inline on all my Creality printers so far in almost the same location. But as I have wanted to upgrade to 40W elements for some time, I am very excited about these. I have ordered several of them and look forward to installing them.

As I'll write the heating elements I ordered along with this... I am REALLY happy with the design of this product. All Creality printers ship with a single pair of wires from the thermistor and the heating element to either the circuit board (as with the Ender 3) or through the braided wire sock to JST connectors near the control box (as on the Ender 5 Pro and Ender 5 Plus) or to a proprietary din connector (as on the CR-10s). This thermistor places a JST connector approximately 12cm from the thermistor which is consistant with the 12v/24v 40W 1M Heading Tube + Header Female Head sold by Banggood. As a result, any time you need to perform maintainance on the hot end or cooler, you can easily completely remove the hot end assembly without having to completely dismantle the cabling of the printer. Excellent choice for this design. I purchases several of these to install on several of my printers. I can't wait!

I used this for converting an Ender 3 to direct drive. This WAS PERFECT. The cable isn't too soft which is a good thing in this case as the rigidity of the cable (along with the others it bundled with) will assist in avoiding dropping onto the print bed. This cable was the same length as the other cables in the printer as well which was a benefit.

This extruder is installed and tested on a Creality Ender 3 as a direct drive configuration. Let me start by saying that it was well worth the effort to use this. I have not experienced any problems with it yet after about 20 hours of printing. I have been printing with BASF PAHT PA15 which is an extremely difficult material to print with. To use this extruder you must change the millimeters per step for the extruder as there is a 3:1 gear ratio in this extruder. There are many videos and websites online which cover how to do this. I have experimented with simply telling Cura to extrude 300% works just fine. Bondtech recommends using more than this though... the Ender 3 for example uses 97 steps per millimeter by default. However, Bondtech recommends 415 steps per millimeter. I recommend properly measuring the amount of filament extruded and going from there. If you're comfortable doing so, you should instead recompile your firmware. I have switched entirely to using PlatformIO for this task and it's been a breeze. Good Luck!

Very nice set of screws. I have been using them with parts printed in PLA. The threads cut nicely. I hope Banggood at some point adds some slightly thinner screws to the set as Raspberry Pi mounting holes are 2.5mm and the smallest screw here is 3mm... and while you can force it... and I have... it would be nice to have thinner screws.

These fans are cheap... I mean... REALLY CHEAP. They are noisy, they rattle, and worst of all the wires break off VERY easily. I highly recommend that before you jostle them at all, you make sure the wires are safely stowed in the cable organizing clips and them use a drop of hot glue to better support the wires. If a wire breaks off while unpacking... peel back the sticker and attempt to solder it back on. Be extremely careful as the wires from the fan are run directly to the board and heating the solder pad to repair it can cause the other wire to fall off. Use as low of a temperature as possible to solder this joint (start at 200 c and work up from there). If you use too high a heat, the wire breaks and it's toast. As for the performance... just WOW... I've had terrible problems 3d printing with these fans in the beginning because no matter how much power I feed the heating elements of the printer, these fans are actually causing at least a 5-10 degree drop in temperature. I've had to cut back to 80% speed to print reliably. The noise level of these fans becomes tolerable at about 75% speed.

I am not very pleased with this product. I purchased it to crimp connectors for Dupont connector pins and this should have been ok for this. Sadly, the locking mechanism is far too tight and the wires keep getting cut by the crimper.
