Introduction

LinkSprite DIY CNC 3 Axis 2418 Engraver Machine is similar with LinkSprite DIY CNC 3 Axis 1610 Engraver Machine , we have increased its working area.

LinkSprite DIY CNC 3 Axis 2418 Engraver Machine laser engraving machine is suit for make non- metal processing such as plastic , wood , acrylic , pvc, pcb, wood or the similar material , etc.And airframe adopt profiles + plastic ,small size, light weight , USB interface , open source GRBL control.

The repeat positioning accuracy is with in 0.1mm under no-load, usually is about 0.05mm. Laser is considered no-load. If you use graver, the precision is depending on the hardness of the material.

And the engraver machine couldn't carve 3 dimensional objects. The different hardness of the material, the different thickness of the carving, and the maximum carving thickness is 30mm. The kit includes xyz stepping motors. You don't need purchase any parts separately, it is enough for working.

About GRBL

Grbl is a no-compromise, high performance, low cost alternative to parallel-port-based motion control for CNC milling. It will run on a vanilla Arduino (Duemillanove/Uno) as long as it sports an Atmega 328.

The controller is written in highly optimized C utilizing every clever feature of the AVR-chips to achieve precise timing and asynchronous operation. It is able to maintain up to 30kHz of stable, jitter free control pulses.

It accepts standards-compliant g-code and has been tested with the output of several CAM tools with no problems. Arcs, circles and helical motion are fully supported, as well as, all other primary g-code commands. Macro functions, variables, and most canned cycles are not supported, but we think GUIs can do a much better job at translating them into straight g-code anyhow.

Grbl includes full acceleration management with look ahead. That means the controller will look up to 18 motions into the future and plan its velocities ahead to deliver smooth acceleration and jerk-free cornering.
