Best Klipper Mainboards in 2026
The BTT Manta M8P V2 is our top pick for new Voron and custom printer builds — its integrated SBC socket, 550MHz MCU, and native CANFD eliminate the need for separate host and CAN bridge boards. For Ender 3 upgrades, the BTT SKR Mini E3 V3 is the drop-in Klipper gateway.
Our Picks
BIGTREETECH Manta M8P V2.0
The Manta M8P V2 combines 8 stepper drivers, an STM32H723 MCU at 550MHz, BTB socket for CB1/CB2/CM4, and native CANFD in one board. It eliminates the need for a separate SBC and CAN bridge, simplifying wiring and reducing failure points. HV driver support up to 60V future-proofs for larger steppers.
BIGTREETECH SKR Mini E3 V3.0
Drop-in replacement for the Ender 3/Pro/V2 stock board. Four integrated TMC2209 drivers deliver silent operation immediately. At $45, it is the cheapest and fastest path to Klipper for the millions of Ender 3 owners. No wiring changes needed — same connector pinout as the factory board.
BIGTREETECH Octopus V1.1
The Voron community standard for 5 years. 8 plug-in driver slots, 6 PWM fan ports, CAN expansion, and thousands of documented configs. At $65 it is $34 cheaper than the Manta M8P V2. Choose it for budget Voron builds or when you want the deepest community support.
Makerbase MKS SKIPR
7 plug-in driver slots and an RPi header for $55. The MKS SKIPR is the cheapest 7+ driver board suitable for Voron builds. Community support is smaller than BTT, but Klipper configs are available and the hardware is solid. Best for cost-conscious builders.
Buying Guide
Stepper Driver Count
A basic Cartesian printer (Ender 3) needs 4 drivers (X, Y, Z, extruder). A Voron 2.4 needs 7+ (X, Y, Z1-Z4, extruder). Count your motors before buying — the SKR Mini E3 V3 has 4, the Octopus and Manta M8P have 8.
Integrated vs Plug-In Drivers
Integrated drivers (SKR Mini E3 V3: TMC2209 soldered on) are cheaper and simpler. Plug-in drivers (Octopus, Manta M8P) let you choose driver models and replace burnt units. For Ender 3, integrated is fine. For Voron, plug-in flexibility matters.
CAN Bus Support
CAN bus reduces the wiring bundle to your toolhead from 10+ wires to just 4 (CAN-H, CAN-L, +24V, GND). The Manta M8P V2 has native CANFD. The Octopus needs a separate U2C bridge ($15). If you plan a CAN toolhead build, factor this in.
DIY vs Pre-Built: Is Klipper Right for You?
Klipper mainboards require firmware compilation, wiring, and config file editing. If that sounds overwhelming, a pre-built printer like the Bambu Lab A1 Mini ($199) prints out of the box with zero configuration. DIY Klipper builds are rewarding but not for everyone.
Frequently Asked Questions
What is Klipper and why use it over Marlin?
Klipper runs printer firmware on a host computer (Raspberry Pi or CB1/CB2) instead of the mainboard MCU alone. This enables advanced features like input shaping, pressure advance, and a web interface. It produces better print quality at high speeds than Marlin on the same hardware.
Can I use these boards with Marlin instead of Klipper?
Yes. All four boards support Marlin firmware. The SKR Mini E3 V3 is commonly used with both Marlin and Klipper. The Octopus and Manta M8P are overwhelmingly used with Klipper in the custom printer community.
Do I need a Raspberry Pi to run Klipper?
You need a Linux host, but it does not have to be a Raspberry Pi. The BTT CB1 ($35) and CB2 ($45) are cheaper alternatives that plug directly into the Manta M8P. The BTT Pi V1.2 ($30) is a standalone option.
What about the BTT Kraken?
The BTT Kraken is a newer 8-driver board with integrated TMC5160 drivers for high-current applications. It is excellent but significantly more expensive (~$200). The Manta M8P V2 with plug-in drivers offers better value for most builds.
Is it cheaper to build a Voron than buy a Bambu?
No. A complete Voron 2.4 build costs $800-1500 in parts plus 40-60 hours of assembly time. A Bambu Lab P1S at $399-699 is both cheaper and faster. Voron builds are for the experience and customization, not cost savings.
Which board for a Voron 0.2?
The SKR Mini E3 V3 is popular for the Voron 0.2 due to its compact size and 4 integrated drivers matching the 0.2's 4-motor layout. The Manta M5P is another option if you want an integrated SBC socket.
