Hi! I'm using the Blackbox controller and I want to trigger a solenoid at a quite high frequency, 4-8 times per second (as much as possible actually). I am exploring the following g-codes: Code: # Use Flooding on/of and connect it to the solenoid M8 G4 P0.02 M9 # or use the 0-10v Analog Output M3 S1000 G4 P0.02 M3 S0 # ... continue Can any of them be electrically or electronically specially taxing to the controller? Thanks!
You shouldn't use the analog 0-10v to run solenoids directly, that would cause damage to the BlackBox. The 0-10v analog signal is just a signal (couple milliamps, meant to be fed into a VFD or similar spindle controller) - it's also not really suited to your case even with additional control circuitry - as its a linear scale, not an on/off. The coolant output should handle it fine, it's what it was designed for: docs:blackbox:connect-coolant [OpenBuilds Documentation] - use a 24v solenoid, try keeping it under 1000mA (Most standard solenoids are around 200-300mA)
Thanks Pete I saw the info about the coolant valve / solenoid but I was worried that the frequency of my intended use (4-8Hz) might be an issue for the controller thanks!
Not an issue for the controller, but will certainly kill the solenoid in a relatively short time, they do have a limited life span.
