Hello,

I have a cnc wood lathe and currently I only use g-code to program it, which is enough since I only produce simple things. The problem is that I cannot control acceleration or deceleration of the axes' movements. For example I want the Z axis start at a certain speed (say F15000) and I want it to slow down until F5000 when it moves 800 mm away. I read somewhere about this and it says we just write the speed code at the end of the line where we specify the end point as coordinates; for instance G01 F15000 / G01 Z825 X-110 F5000 (slash stands for next line). Supposedly it starts at F15000 and it is at Z70 X-80 for example, and it becomes F5000 when came to Z825 X-110. But this doesn't work! It just perceives the F code at the end of the last line as the speed of the whole movement. So I couldn't manage to observe any acceleration or deceleration that way.

Anybody has any knowledge about this and a suggestion? Even if you have any idea, please tell, I most probably need it!
