BIGTREETECH SKR Mini E3 V2.0 New Upgrade Control Board 32Bit with TMC2209 UART Driver 3D Printer Parts Cheetah V1.0 for Ender3 (with BLTouch)

• 1) If you encounter any problems, please contact us through Amazon as soon as possible. We have professional after-sales technical staff to solve your problems.
• 2) Because the fan on the SKR Mini E3 V2.0 control board is a CNC fan, you need to set the wind speed before using it.
• 3) Compatible with BLTouch, RGB color lights, occlusion detection, stop and other functions.
• 4) BLTouch is an automatic level sensor for 3D printers based on open source. Simple, intelligent, highly precise. It can be used with all types of bed materials such as glasses, woods, metals, etc.

BL TOUCH1. An additional power supply may be needed in case your board does not supply enough current at 5V.2. Set Zmin pull-up on your firmware when using Logic Free (In most cases, it is already set up).3. If push-pin deploy fails, turn the core by up to 180 degrees with an Allen-key so that the core is further inside the casing.4. Depending on your type of 3D printer, you may need to remove or add some parts to the controller board.5. In principle, a controller board with a large capacitor in the end stop input circuit is not supported. (You may need to remove such a capacitor from your board)6. If noise, etc. interference is expected, you should use an anti-interference extension cable (Shielded or Twisted Cable).7.
