Retool A2

Elias Bakken — Sun, 16 Feb 2025 12:07:17 +0000

Retool is an extruder control board that is powered and controlled with USB for placement on the tool head. It is designed to work with Recore, but should work well with just about any Single Board Computer (SBC) that is used with Klipper.
The tool board has one TMC2209 stepper motor driver, 3 fan outputs with tachometer feedback, a port for attaching a peltier element, one connector for a thermistor, two connectors for end stops, one port for an inductive sensor and one connector for connecting a string of Neopixels. The board also has a built in ADXL345 accelerometer for doing input shaping. There are indicator LEDs on all outputs, both on the front and back, so the front can be covered with a hat sink while still being able to show the output status. There is also a Type C USB controller chip mounted for proper power negotiation between the tool head and Resend A2, the companion voltage injection board. This is added as a future improvement, and has not been properly implemented in software. The Resend A2 board has the same chip (FUSB302B). The main MCU is an RP2040 and the board comes pre-flashed with Klipper.

Revolt

Revolt is an add-on board for Recore that adds two high voltage TMC2160 stepper drivers. This is great if you have a cartesian or coreXY printer like the Voron 2.4. Revolt comes with a connector the allows you to use a separate power supply of up to 48 V. The maximum current for each of the stepper drivers is 3 A.
For more information on mounting and setting up the board, see the wiki page for Revolt A2.

Restep A1

Restep is an additional stepper for Recore. This allows up to 8 steppers to be used with Recore, making the printer perfect for Voron 2.4.
It has a TMC2209 stepper driver, the same that is on the main board. This driver can be used for both S6 and S7 on Recore A6 and A5. For A5 use, it is necessary with a cable from this board down to one of the pins on S6/S7.

Remove A1

Remove is a small accelerometer sensor for input shaping in Klipper. It’s an ADXL345 with an RP2040 and a USB connection. The PCB itself weighs 2 grams, but the cable adds some additional weight.
