E3 Free-Runs vs V4.2.7?

The main benefit of the E3 Free-Runs over the V4.2.7 is UART control over the stepper drivers. This means no messing with multimeters to set the motor current and/or stepping mode. In our opinion, this is worth the extra couple of $ over the V4.2.7

What does this board do?

This is a budget silent board from Creality themselves. It is a decent low-cost alternative to our EZBoard. This board is supported in our Unified 2 firmware multiple 3D printer models (see below). If a printer is not specifically listed below, it is not officially supported by our firmware.

Features/Details

• Genuine Creality E3 Free-Runs board with Trinamic TMC2209 Drivers
• Guaranteed Genuine STM32 CPU – With manufacturers swapping out STM32 CPUs in favor of knock-off chips, we are opening and checking EVERY board before shipment to ensure it has a genuine STM32 CPU on it as well as what memory size they have.
• 512K Flash Memory with EEPROM support
• This board has a bootloader that allows updating the firmware from the MicroSD card
• Uses USB C Cable (Included)
• Works with the below printers:
  • CR-10
  • CR-10S
  • CR-10 Mini
  • CR-10S Mini
  • CR-10 S4
  • CR-10S S4
  • CR-10 S5
  • CR-10S S5
  • Ender 2 Pro – Requires our stepper motor cables
  • Ender 3/3 Pro
  • Ender 3 NEO
  • Ender 3 V2
  • Ender 3 V2 NEO
  • Ender 3 MAX
  • Ender 3 MAX NEO
  • Ender 5/5 Pro
    • Ender 5 machines will likely need our LCD EMI filter board due to how Creality designed this board.
  • Ender 5 Plus – LCD Kit Required and Dual Cable LCD Adapter Board Required
• Unified 2 Firmware included FREE via digital download – Ships with Testing Firmware, you will need to flash it for your machine with a SD card and a Computer
• Compatible with EZABL, EZOut Filament Sensor Kits, and BL Touch Probes
• VREF is set in firmware digitally
• If using the Dual Cable LCD adapter board please read the installation page here for it: https://support.th3dstudio.com/helpcenter/creality-dual-cable-lcd-adapter-board-installation/ 

CR-10 Model Support Notes (Read this BEFORE buying for a CR-10 Series)CR-10 (Regular, Mini, S4 S5)

• Models with 2 separate Z Motor connectors need the Dual Z Motor Adapter Addon
• MOSFET needed for the bed if your machine does not already have one (addon above)

CR-10S (Regular, Mini, S4 S5)

• Needs Creality Dual Cable LCD Adapter Board if you do not have the EXP3 header on your LCD.
• If you have the EXP3 header on your LCD use 1 cable to connect from the EXP3 to our board and you will then not need the dual adapter board.
• Models with 2 separate Z Motor connectors need the Dual Z Motor Adapter Addon
• MOSFET needed for the bed if your machine does not already have one (Found here)
• Does NOT work with Touch Screen Models

Important Information

• Make sure to have an active cooling fan over the board to keep it cool. The Trinamic drivers run warmer than boards with the “standard” (aka 4988 series) drivers.
• On some machines, the EMI filter board addon is required, specifically Ender 5 machines.
• Because the stepper drivers are not connected to UART for control (they are in standalone mode) Linear Advance does not work on this board.  If you are not going to use Linear Advance (most people do not) then this does not apply to you.
  • If you want to use Linear Advance we recommend using our EZBoard instead as it works correctly with Linear Advance.
