Prunt Motion Controller

Prunt is an advanced open-source motion control system targetted at 3D printers. Prunt includes features not found in other popular open-source systems, including:

• Corner blending with user defined deviation.
• Constrained and independently adjustable velocity, acceleration, jerk, snap, and crackle.
• Pinout data provided by the board to eliminate the need to edit pin mappings in a configuration file.
• Built-in GUI for configuration editing without the need to ever edit configuration files directly.
• Safer and faster homing by defining maximum overshoot distance instead of speed.

We also sell our own hardware with features not present on most consumer 3D printing hardware:

• Fully isolated USB to protect upstream devices.
• Reverse polarity protection.
• Protection against electrical shorts to 24V on most exposed pins.
• Individual hardware timers for every stepper, allowing for precise step timings.
• Support for 2-pin and 4-pin fans on the same ports.
• Fail-safe firmware updates, eliminating the need to ever install a jumper.
• Hardware counters for high speed fan tachometers.
• Soft-start to allow a wider range of power supplies.
• PT1000 support without jumpers.

Currently we are selling a small number of units for those who want to beta test our hardware. These are early units for people that want to mess with new hardware and firmware, they’re not currently suited to people that want a product that just works. This is reflected in the price of $100 USD being far below the BOM cost, so expect these to be more expensive in the future, but potentially have issues now. Send an email to liam@prunt3d.com if you would like to purchase one of these early units.
