Jackpot3 CNC controller

The Jackpot3 CNC Controller is a 32bit dual-core 240mhz control board.

Full details and up-to-date information is here, https://docs.v1e.com/electronics/jackpot3/

• Built in wireless control software
• WiFi, Bluetooth, or hardwired capable (esp32).
• 6x TMC2226 drivers (nearly identical to the 22209 with better heat transfer)
• 7 inputs, 4x 5V(full PWM capable) or 24V(PS input level) outputs (only basic PWM).
• One expansion FluidNC module socket (more IO, or other specialty add on cards).
• MicroSD card slot.
• Integrated RJ11 socket, for a pendant or Airedale expander.

The Jackpot3 CNC Control board runs FluidNC which is fully GRBL compatible with extended features featuring easy configuration and updating, or GRBLHal(upcoming).

• ESP32-wroom-32 Based control board

  • 32bit dual-core 240mhz board.
  • WiFi, USB Direct connection, or Bluetooth (rarely used).
  • Can have Onboard antenna
  • USB-C

• 9-24VDC

  • Current required is a minimum of 19W (24Vx0.8A).
  • If you plan on using the high current outputs adjust accordingly.

• 6x Integrated Stepper drivers

  • TMC2226 drivers in UART control mode only
  • The sockets are labeled XYZABC, but you can use any socket for any axis or motor number. The letters are for reference only.
  • No Stallguard

• 7x Inputs

  • All switch inputs are active low.
  • They have a 10k pullup external to the ESP32. The signal pin (S) should be connected to the ground pin (G) to activate the switch.
  • The input pins can be pins in the config file to use Normally Open or Normally Closed inputs.

• 4x 5V or Line level outputs (same as input voltage)

  • Can be used to drive 2.5A continuously before they overheat. You can use them intermittently up to 3.5A.
  • They can be used with inductive loads (solenoids, relays, DC fans/motors)
  • See the “Spindle” section of the FluidNC wiki for common uses
  • Full PWM on teh 5v port, basic/slow PWM only on the 24V port.

• 1x Expansion Module socket

  • 6 PACK expansion module source
  • Buy Them
  • This should be able to use any CNC I/O module. Use an 11mm standoff or a 3D printed support in the mounting hole provided.
  • These Modules can be just about anything you need, pendant, more inputs, outputs, relays, spindle, VFD, Servo, OLED…

• 1x MicroSD card slot

  • larger than 2gb needed
  • Fat32
  • 30 character or less file names, 100 character or less file location

• Firmware

  • FluidNC
  • Text based config file for simple firmware edits.
  • No compiling to flash a board or change the configuration.
  • ~100% GRBL compatible
  • ESP3D-UI
  • Or GRBLHal

• Dimensions

  • CAD/Step link - needed
  • 80mmx100mm Board footprint
