BIGTREETECH SKR Mini E3 V3.0 Control Board +TFT35 E3 V3.0.1 Touch Screen Display 32Bit Silent Board Integrated with TMC2209 UART Stepper Driver Compatible with Ender 3/5 Ender 3 Pro/V2 3D Printer

I replaced my sky 1.4 Turbo board that was in my Sidewinder X1 after it had a short. This board was smaller and easier to use, while having a performance boost. While this board is perfect, it does not natively support the powered inductive or optical sensors used by some printers, such as the Sidewinder X1. I am sure a workaround is available by powering the endstops off a 5v supply, but it didn't work for me. HOWEVER, the board does support sensorless homing which required just 2 small changes in Marlin and works perfectly, so in a way, it was quicker to setup than using sensor endstops. I use to be against sensorless homing, as I thought it wouldn't be precise enough, but I was wrong, as my prints are just as good as with my inductive endstops, and I don't have to worry about an endstop failing. I do use a BLtouch for bed leveling though.

Bought this for my Ender 3 V2 with a 4.22 board. I was a little nervous installing it myself, but it ended up being much easier than I thought. I think the first board was defective (or maybe operator error) but they immediately sent a new board out and returning the other one was painless. Once I got the second one hooked up it worked just fine with the software. It's so quiet compared to the stock board. It loads quickly and I am super happy that the estimated completion time is way more accurate than the OEM board. It's been performing well with no hiccups after updating the build. It was plug and play, but I updated to to the most current version of Marlin. The only thing I didn't think about when I bought this board was adding wifi. If you are thinking about going that route, look up boards that already have it installed, so you don't need an extra component (unless you want it that way). I plan on going wifi soon for the convenience and so my 9 year old can start a print without having to be to close the the printer in case it's hot. So I will have to get a lil pi and program it accordingly with klipper.

Like the touch screen but it was not very live adjusting friendly tried for hours to get my baby steps down to a point it would print. And never did get a print out of it. The mother board is hard to configure in marlin which was the only way I could use it because the stock firmware wants you to use the z stop and not the bltouch port but once I got that programed I never could get the hotend fan to work except with the stock firmware. The marlin terminal on the screen never worked when I would stop a print to do an adjustment the screen would sit on a screen saying system busy and never go back to a operating mode. Switched back to the creality 4.2.7 not as many options with it but at least I don't have to be a scientist to compile marlin for it. Well after some trial and error I got it working after using marlin it just takes time to get use to klipper and how to set it up. It works great live the board so I changed my review to 5 stars.

I have an Ender 5 Pro and purchased this to replace a failed stock motherboard and touchscreen. I wired it up without much issue and confirmed all of the steppers, heaters, and fans work. The BLTouch is completely worthless - I get error after error for seemingly no reason. After hours of searching, I found several people saying the prebuilt firmware is garbage. OK, no problem. I compiled my own based on settings in the Marlin config files. That seemed to fix some of the BL Touch issues, and I was eventually able to get through a bed leveling. Then the other problems started to come. First, I can't connect this to my PC via USB. It's an unsigned driver, which is against the law for WIndows 11. I can go through the process of restarting my PC into recovery mode and stop enforcing driver signatures, but that only works for one power cycle of the printer. If I reboot the printer, I have to reboot my PC. Unacceptable. I figured I would at least get through a test print and worry about the USB issues later - nope. I sliced a test cube in Cura, which estimates the print to take 30 minutes. I load up the SD card, walk back to my printer, and start the print. 3 seconds. The printer homes and then calls the print finished. If you're going to stay with Marlin, don't waste your time on this piece of trash. Buy a Creality board and save yourself the headache.

My screen heats up to pretty dangerous temperatures when at full brightness and starts warping the image in the lcd. I had to turn it down to 50% to make it useable. Otherwise as advertised. More documentation would have been nice but works as it should. The silent stepper drivers are amazing and loads up firmware just fine.

While this board is compatible with the CR10 S5, there are a number of things you should know before buying * If you plan to run klipper, the TFT display is not compatible without a decent amount of additional wiring to your raspberry Pi * When running a BLTouch, the instructions are WRONG. You must attach the "sense" wire to the Z endstop plug (PC2 in Klipper). It will not work in the main IO pins. The rest of the BLTouch wires to connect to the IO slot as the instructions indicate. * You will need to put new connectors/crimps on the end of your BLTouch. One side will get swapped to Dupont connectors, the other to JST connectors. * While it supports dual Z, it uses a single stepper driver so the Z screws cannot be operated independently (You cannot do gantry leveling) * You will need to build a splice cable as there are not enough fan headers for all the fans in the CR10 S5 (You will need to make a split connector for both the fans in the controller case) * The USB & SD slots do not face the correct way in the CR10 S5. You will need to make cutouts in your case to run the USB cable. The USB card can only be accessed by opening the controller case. Now that the bad things are out of the way, here's the good. * This is INSANELY quiet. It is way quieter than my Ender 3 with the Creality brand silent board. * Tons of features and works great with Klipper. * Speed is every bit as good as the stock board (that's mostly limited by the size of the moving bed)

Fantastic little combo. Targeted for the Ender 3, I used it for a Monoprice Select 3D to replace a fried main board. Getting Marlin configured took some time, but the SKR mini e3 v3 perfectly matched the Monoprice interface requirements.

Installed on an Ender 5 Plus. This little kit was just what I was looking for. It's a fun DYI upgrade project. Just go online to figure out the pinouts of all the wires for your specific printer if you don't know them. Also, there is tons of ready to use firmware you can find for just about every printer as well. If I ever have an issue with this board I'm going to upgrade it to the bigger SKR 3 board but I think this thing will work just fine for a long time, Happy with the purchase!

Needs a bit more documentation on set up.
