Programmable Coolant Nozzle part 2

A bit of machining content on the programmable coolant nozzle.
The angle is calculated (simple arc tan) for each tool based on the tool length, and if diameter is larger than 20mm it is also taken into account. If the tool type is hole making, then a sweep is set for a few degrees. The only gcode used in the main program is m7. This angle/sweep command is sent from linuxcnc via serial interface to an esp32 which is connected to an rc servo via ttl to rs485 converters so as to withstand the long line of transmission without interferences.

Glad to see you back, love your mill modifications and use of linuxcnc

[@juliawls]

Great to see you back. Looking forward to more

You definitely want the coolant turned off before the nozzle parks 🙂 Although it would be comedy gold to see it spray your workshop once. Great video, as always, and I look forward to seeing more in the future.

Lol 😂 yes, even though until the enclosure is finished I’m only running mist and air, I have a delay between coolant off and go to park position, atm 1.4secs or so. The other hazards are crash into the atc, safeguarded by the laser registering the park position and, poking my eyes - rather the safety googles 😢

Beautiful!! Great job

The Linuxcnc God...😁👍

Top. Are you running this in Mach3? What type of mechanism controls the angle of the nozzle?

[@PWLopes9000]

Linuxcnc. The angle is calculated (simple arc tan) for each tool based on the tool length, and if diameter is larger than 20mm it is also taken into account. If the tool type is hole making, then a sweep is set for a few degrees. The only gcode used in the main program is m7.
