## TMC2130 Pen / Laser Controller
This is a simple controller for a Pen Plotter that uses Grbl_ESP32 as the firmware and TMC2130 stepper motor drivers in SPI mode. There is a hobby servo connector for pen up/down control. The PWM signal (3.3V TTL) on that could also be used to control a laser module.
### Features
- ESP32 Controller Socket
- SD Card Socket (under ESP32)
- (2) TMC2130 Stepper Driver Sockets (SPI Mode). Note: Non SPI drivers will not work.
- (2) Limit switch connectors
- Hobby Servo connector
- Strong 5V 3A power supply
- All the freaking awesome features of Grbl_ESP32
### Firmware
The firmware used is Grbl_ESP32. There is a special branch that supports the TMC2130.

### Version History
- V2
- Moved X Limit Switch form GPIO 2 to 32. Works better on dev boards that have an LED on that pin.
- The footprint for the stepper drivers no include the diag pins
- Added jumpers to optional connect diag pins to limit pins
- Grounded TMC2130 N/C pin to make it compatible with TMC5160 drivers. The capacitor size is probably not ideal for use with the full capacity of the TMC5160, but should work.
- Added 5V output (fan connector)
