If you are having PCBWay assemble them, this is a 4 layer board, the layer names are shown above. They want them listed top to bottom.

Basics¶

The Jackpot CNC Controller is a 32bit dual-core 240mhz board, WiFi, Bluetooth, or hardwired capable (esp32). It has 6x TMC2209 driver ports, 7 inputs, 2x 5V outputs, 2x input level outputs, one expansion module socket. MicroSD card slot. The board runs FluidNC which is fully GRBL compatible with extended features and easier configuration.

Specifications¶

ESP32-wroom-32 Based control board

32bit dual-core 240mhz board.

WiFi, USB Direct connection, or Bluetooth (rarely used).

Onboard or external antenna

Micro USB, or USB-C

Socket based for easy swapping if anything were to ever go wrong, or you want to quickly change configs.

38 pin - ESP32-DevKitC CP2102 - MicroUSB, These seem to be the most reliable.

25.4mm header width

9-24VDC

Current required is a minimum of 19W (24Vx0.8A).

If you plan on using the high current outputs adjust accordingly.

6x Stepper driver sockets

This controller is designed for use with TMC2209 drivers in UART control mode only

Typically, TMC2209 drivers are limited to 4 addresses. This controller uses a CS (chip select) pin for 3 of the drivers to allow 6 drivers to be individually controlled.

The sockets are labeled XYZABC, but you can use any socket for any axis or motor number. The letters are just for reference only.

No Stallguard

7x Inputs

All switch inputs are active low, the LED goes on when ground is connected to the pin.

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 5V Rail is optional and is used for external switches that require 5V.

Define the pins in the config file to NO or NC like this…

Define an N.O. switch like this. gpio.xx.low

Define an N.C. switch like this. gpio.xx

2x Line level outputs (same as input voltage)

PWM Capable

The MOSFETs switch to ground. You can use any voltage up to the VMot max as the positive, as long as it uses the same ground reference.

Can be used to drive 2.5A continuously before they overheat. You can use them intermittently up to 3.5A. If using above 2.5A you should test to see if they start to overheat.

They can be used with inductive loads (solenoids, relays, DC fans/motors)

2x 5V outputs

PWM Capable

These will source and sink about 25mA each.

Most commonly used for tool SSR’s and Lasers.

See the “Spindle” section of the FluidNC wiki for common uses.

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, 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

Custom ESP3D-UI which includes a tablet mode with Gcode viewer.
