about coolant! #38

Open byronin opened 3 years ago

byronin commented 3 years ago

If there is no heat sensor, what is a coolant for, for why, and how is it used?

RudyFiero commented 3 years ago

Coolant is what runs over the tool tip and the part when it is being machined. Machining causes heat.

@RudyFiero I understand that if there is a milling job, we assume that the tip is hot and we run the cooler. https://gcodetutor.com/gcode-tutorial/cnc-m-codes.html M08 & M09 Example: N1 T0101 (10MM ENDMILL); G21; S700 M03; G00 X175.0 Y25.0 Z-10.0 M08; // onn Z-6.0; M09 ; // off

i'm sorry for those silly issue
