User questions & answers

Question:	Will this board work with the anycubic i3 mega-s
Answer:	It's likely your firmware overwrote the bootloader. Just burn a new bootloader onto the chip or use an AVR ISP programmer to upload your firmware without a bootloader.
Question:	what can i use a cnc fan port for
Answer:	I guess technically you could make this work for nearly any printer. It's an open source board that allows you to load up your own firmware and program it as you wish. Would likely need to rewire stuff and make custom mounts unless the printers stock board is an mks 1.4
Question:	Does this have thermal runaway protection enabled
Answer:	I have yet to order this board, but I am aware that marlin anet a8 config is available to flash to this board. The same steps as you would with the anet a8 minus a few connection changes for the board type, other than that you should have no issues with marlin , this board, and the anet a8.
Question:	Are the tmc2208 already soldered for uart? or will you need to make modifications to the drivers
Answer:	Both will work well

User questions & answers

Question:	Is this compatible with the CR-10 v
Answer:	Hi, I’m fairly new to 3d printing, but I’ll try to help. I’ve posted to several message boards in the past only to get nothing, and I hate that... First, please include your printer type. I have a CR-10 v3, and I didn’t have to adjust the x or y offsets. It may have been included in the firmware update I installed after adding the BLTouch. Part of my installation required flashing the firmware of the printer to include auto bed leveling commands/options. I would suggest finding your printer’s firmware with the modifications for the BLTouch. Unless you have an obscure brand, it should be available for download from the internet. I hope this was helpful.
Question:	is this a genuine bltouch or a clone, from my research this is something that will determine settings when setting up the firmware
Answer:	not the cable. but the the skr mini e3 is running marlin. you need the split end to connect it to the board with no cutting. you should be able to find the firmware without issue. but you will need to purchase the bltouch that has 2 connectors at the end of the cable and not 1
Question:	Is it possible to program the firmware as needed for the bl to work using a mac? or windows only
Answer:	I used the most current stable release of smith3d firmware. Works a treat.
Question:	I have the cr-10 v3, but i have seen installations with have different wiring order to the pins. which color is which connection on the 10 v2/v3 vers
Answer:	I bought my Ender 3 in June 2020, it arrived with a V4.2.2 board installed which is a 32bit board. If you have a MINI USB connector on your printer, it is an 8 bit board, but if it's a Micro USB then you already have the 32 bit board installed. The V4.2.7 board being sold here is a 32bit board. This board also has a socket specifically for the BLtouch, and a filament out sensor.

User questions & answers

Question:	does this come with firmware installed or do i need to via Audrino
Answer:	If you use Marlin firmware, you'll need to build the firmware that is specific to your machine. You'll need to use Visual Studio Code along with the PlatformIO extension.
Question:	Can one of the heater outputs be used to provide a constant 12v output for a pump I use for water cooling? Is there any documentation for it if so
Answer:	Yes with some changes in Marlin but that board has two always on 2 pin ports. If you are you using a 12 volt power supply these two ports will have a constant 12v when the board is switched on. If you are using a 24v power supply you will need a buck converter to step it down to 12 volts.
Question:	what board definition do we use to compile the audrino firmware
Answer:	In PlatformIO use BOARD_BTT_SKR_PRO_V1_1
Question:	Are TMC2209 drivers supported
Answer:	Very much

User questions & answers

Question:	This thing seems to not want to upload marlin firmware after the first time. this is on osx. is there anything special to it
Answer:	The cable is about 3feet long.
Question:	Will this work with a CR
Answer:	GX has more DAW functionality , hardware buttons and LEDs. If DAW control is important to you, the GX is worth the extra money to be able to set and go to left/right locators, open windows, engage cycle and control track volume without parameter jumping and more. SE49 is more basic in that it mainly offers play/stop, record, forward, rewind and track change.
Question:	does anyone have a marlin firmware for this board that is compatible for the anet a
Answer:	Works with win 7 and 10...

User questions & answers

Question:	Will this work with the stock board in a CR10 or do I need to upgrade the board as well
Answer:	It will work with a stock board but you will need to modify and recompile Marlin to work with a 12864 in configuration.h (#define REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER). and comment out CR10 Display. If all of what I typed looks like gibberish to you, don't buy this lol.
Question:	will this controller work with ramps 1.4 and arduino
Answer:	Yes, it will. You will need the LCD adapter to connect the EXP1 and EXP2 cables to AUX3 connector of the RAMPS board. Without any firmware updates, the latest version will detect that you've connected to an old 12864 interface and then emulate that interface. It works, but, for me, the display is somewhat erratic, occasionally displaying random garbage where there are supposed to be characters, but the mess corrects itself with the next screen update. Usable, but annoying.
Question:	Can this be connected to and function as a touch screen on the gt2560 for a20m
Answer:	I have tried to follow their videos to switch it to touch screen but I couldn’t make it work

User questions & answers

Question:	Are there any online instructions? the answer "we can provide instruction manual" doesn't anyone who buys this and you provide instructions in box
Answer:	Follow the instructions for the machine you are building. Or, google ramps 1.4 for a lot of info.
Question:	Can you run a nema 23 with this
Answer:	You can run nema23, nema17 and possibly others. The 5 A4988 drivers which run the motors are versatile, but very noisy. If too loud, you may opt to trade them out with TMC2208 drivers. They are a little more expensive than the A4988 drivers, but they are a drop in replacement and are very quiet,
Question:	What is the voltage? I'm not sure what kind of power supply to get
Answer:	You will need a 12v power supply for the ramps boards to drive your steppers. Make sure to get high enough current for your steppers, fans and heated plate if needed. Less than $20 on Amazon
Question:	Need instruction manual please or a point to recommended instructions online
Answer:	Best i can answer is to follow the guide for whichever machine you are building. You can also Google ramps 1.4 and get a ton of info there.

It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started. The Mega is compatible with most shields designed for the Arduino Duemilanove or Diecimila.DC Current for 3.3V Pin:50 mADC Current per I/O Pin:40 mA

Mega Pololu Shield Compatible (RAMPS 1.4 Shield)

It is a Mega Pololu Shield, or RAMPS for short,designed to fit the entire electronics needed for a RepRap in one small package for low cost. RAMPS interfaces an Arduino Mega with the powerful Arduino MEGA platform and has plenty room for expansion. The modular design includes plug in stepper drivers and extruder control electronics on an Arduino MEGA shield for easy service, part replacement, upgrade-ability and expansion. Additionally, a number of Arduino expansion boards can be added to the system as long as the main RAMPS board is kept to the top of the stack.

LCD 12864 with Controller

This full graphic Smart Controller contains a SD-Card reader, an rotary encoder and a 128 x 64 dot matrix LCD display. You can easy connect it to your Ramps board using the "smart adapter" included.

After connecting this panel to your Ramps you don't need your pc any more, the Smart Controller supplies power for your SD card. Further more all actions like calibration, axes movements can be done by just using the rotary encoder on the Smart Controller. Print your 3D designs without PC, just with a g-code design stored on the SD card.

User questions & answers

Question:	Description says you need an external dc5v power supply module to supply power to tft screen, bl touch and neopixel. can this be provided via usb
Answer:	I bought my Ender 3 in June 2020, it arrived with a V4.2.2 board installed which is a 32bit board. If you have a MINI USB connector on your printer, it is an 8 bit board, but if it's a Micro USB then you already have the 32 bit board installed. The V4.2.7 board being sold here is a 32bit board. This board also has a socket specifically for the BLtouch, and a filament out sensor.
Question:	Does this fit cr10s pro v
Answer:	I haven’t done it, but you can install something like the BLTouch to perform bed levelling.
