以前制作過CNC雕刻機(jī)，是用MACH3作為上位機(jī)控制，硬件是采用PC接并口輸出脈沖和方向使能信號(hào)經(jīng)過隔離驅(qū)動(dòng)步進(jìn)電機(jī)驅(qū)動(dòng)器，步進(jìn)電機(jī)驅(qū)動(dòng)是采用TB6560芯片控制。最后就接到步進(jìn)電機(jī)。機(jī)械是用鋁合金制作，主要部件有三個(gè)1605的滾珠絲杠，多個(gè)運(yùn)動(dòng)滑塊等制作。用這臺(tái)DIY CNC雕刻機(jī)可以雕刻木頭塑料等東西。當(dāng)時(shí)沒有一直玩下去，現(xiàn)在發(fā)現(xiàn)網(wǎng)上有用單片機(jī)制作的雕刻機(jī)挺精巧的現(xiàn)在分享給大家。
GRBL CNC 3D打印機(jī)，這就是我說的可以用單片機(jī)來控制的3D打印機(jī)，我先照著百度科普下grbl，Grbl是性能高，成本低，基于并口運(yùn)動(dòng)控制，用于CNC雕刻。它可以運(yùn)行在Vanilla Arduino (Duemillanove/Uno) 只要它配備了Atmega 328型芯片。控制器由C編寫并優(yōu)化，利用了AVR 芯片的每一個(gè)靈巧特性來實(shí)現(xiàn)精確時(shí)序和異步控制。它可以保持超過30kHz的穩(wěn)定、無偏差的控制脈沖它接受標(biāo)準(zhǔn)的G代碼而且通過了數(shù)個(gè)CAM工具的輸出測(cè)試。弧形、圓形和螺旋的運(yùn)動(dòng)都可以像其他一些基本G代碼命令一樣完美支持。函數(shù)和變量目前并不支持，但是會(huì)作為預(yù)處理器包含在將來發(fā)布的版本之中。 Grbl 包含完整的前瞻性加速度控制。它意味著控制器將提前16到20個(gè)運(yùn)動(dòng)來規(guī)劃運(yùn)行速度，以實(shí)現(xiàn)平穩(wěn)的加速和無沖擊的轉(zhuǎn)彎。Grbl是性能高，成本低，基于并口運(yùn)動(dòng)控制，用于CNC雕刻。它可以運(yùn)行在Vanilla Arduino (Duemillanove/Uno) 只要它配備了Atmega 328型芯片。控制器由C編寫并優(yōu)化，利用了AVR 芯片的每一個(gè)靈巧特性來實(shí)現(xiàn)精確時(shí)序和異步控制。它可以保持超過30kHz的穩(wěn)定、無偏差的控制脈沖它接受標(biāo)準(zhǔn)的G代碼而且通過了數(shù)個(gè)CAM工具的輸出測(cè)試?；⌒巍A形和螺旋的運(yùn)動(dòng)都可以像其他一些基本G代碼命令一樣完美支持。函數(shù)和變量目前并不支持，但是會(huì)作為預(yù)處理器包含在將來發(fā)布的版本之中。 Grbl 包含完整的前瞻性加速度控制。它意味著控制器將提前16到20個(gè)運(yùn)動(dòng)來規(guī)劃運(yùn)行速度，以實(shí)現(xiàn)平穩(wěn)的加速和無沖擊的轉(zhuǎn)彎。很棒吧！開始玩起。

還沒有雕刻機(jī)的機(jī)械部分可以用廢舊光驅(qū)制作個(gè)微型雕刻機(jī)運(yùn)動(dòng)平臺(tái)。雕刻機(jī)最重要的是主控程序這次用 Arduino/AVR328單片機(jī)，價(jià)格在15元左右，主控程序是上面提到的目前很火的開源的GRBL，還有一種基于STM32平臺(tái)的開源主控程序Dlion也不錯(cuò)可以替代grbl。如果從性能比較這兩個(gè)方案，顯然是stm32平臺(tái)運(yùn)行速度更快畢竟他是32單片機(jī)呀！

下面介紹小這個(gè)些主控程序主要干的事，通過串口PC和主控板通訊，PC命令給控制板，控制板接收命令做不同的響應(yīng)，PC可以發(fā)G代碼給主控板，接收完成后可以自動(dòng)開始雕刻任務(wù)。
      在介紹下G代碼因?yàn)镚代碼是雕刻機(jī)的核心部分
G代碼是數(shù)控程序中的指令。一般都稱為G指令。
G00------快速定位
G01------直線插補(bǔ)
G02------順時(shí)針方向圓弧插補(bǔ)
G03------逆時(shí)針方向圓弧插補(bǔ)
G04------定時(shí)暫停
G05------通過中間點(diǎn)圓弧插補(bǔ)
G06------拋物線插補(bǔ)
G07------Z 樣條曲線插補(bǔ)
G08------進(jìn)給加速
G09------進(jìn)給減速
G10------數(shù)據(jù)設(shè)置
G16------極坐標(biāo)編程
G17------加工XY平面
G18------加工XZ平面
G19------加工YZ平面
核心就是解析G代碼，完成步進(jìn)電機(jī)驅(qū)動(dòng)，和控制主軸開啟關(guān)閉，還有插補(bǔ)算法，直線插補(bǔ)，圓弧插補(bǔ)，還有一些步進(jìn)電機(jī)的加減速算法。

      memset(&sys, 0, sizeof(system_t));       // 清除所有系統(tǒng)變量
      sys.abort = true;                         // 中止標(biāo)識(shí)位置位
      sei();                                        // 使能中斷

// Auto-cycle start has two purposes: 1. Resumes a plan_synchronize() call from a function that

// as a beginner tool, but (1.) still operates. If disabled, the operation of cycle start is
// manually issuing a cycle start command whenever the user is ready and there is a valid motion
// command in the planner queue.
// NOTE: This function is called from the main loop, buffer sync, and mc_line() only and executes
// when one of these conditions exist respectively: There are no more blocks sent (i.e. streaming

// program, primarily where there may be a while loop waiting for a buffer to clear space or any
// point where the execution time from the last check point may be more than a fraction of a second.
// This is a way to execute realtime commands asynchronously (aka multitasking) with grbl's g-code

// set the system realtime flags, where only the main program handles them, removing the need to
