For the basics, profiling the material works really well, but for more detailed programs, it is kind of useless. ### 5/5 — 打不开 *2025-01-01* 你好这个付钱之后，打开一片空白，能不能退钱 ### 1/5 — Plase hungary league *2024-11-13, version 2.1.0* the majority of Hungarians do not use it, because there is no Hungarian language ### 4/5 — 使用说明书 *2024-06-26* 怎么使用 ### 1/5 — LJ *2023-11-22* LJ骗钱 ### 1/5 — 一点都不好用，不可以自动生成代码。考虑清楚再买 *2023-06-06* 后悔 ### 1/5 — 软件不能指定圆的半径编写圆 *2023-05-30* 对于我这种初学者来说这软件只能说一般，最让我头疼的是只知道圆弧半径r时，里面不能输入r半径。G02不能连续用，意思是不能两个圆一起走刀。我晕了，还花了我三十多块钱下这个软件。 ### 1/5 — Es werden Funktionen gepriesen die nicht funktionieren *2023-05-12* G73 wird nicht als Befehl anerkannt genauso wie G72 es wird in der Produktbeschreibung beschrieben das die Grundlagen der CNC Technik in dieser App sind die oben genannten Funktionen sind grundlegende Sachen. ### 1/5 — 垃圾 *2023-04-25* 垃圾 别下载 ### 1/5 — Total SCAM: DON'T buy this... teh USER interface is TERRIBLE... *2023-03-05* Total SCAM: DON'T buy this... teh USER interface is TERRIBLE... Zero didactics, ZERO logic, ZERO use... I am a pro G-code CNC programmer and USA engineering professor... wanted something simple for my students... Total SCAM: DON'T buy this... teh USER interface is TERRIBLE... ## Frequently asked questions about CNC ### What does this CNC app do?
