I'm thinking how best to implement these.
I could use either encoders, or potentiometers.
.
My current thought is encoders, as overrides could then be reset in software, but when would you want to reset them?
I'd have the ability to program things to reset whenever I wanted, but when would that be?
When you disable the override?
When a new feedrate is called?
.
Then do you reset them when re-enabling the overrides?
.
At the moment, I rely on onscreen overrides which you have to manually reset to 100%, however I can think of situations where all the above could be handy, so I'm struggling to make decision.
.
Regarding the encoder v. pot, I'm thinking encoder, as there could potentially be several meters of wiring needed between the control panel and cabinet, so a high value pot would be susceptible to noise, which could cause unwanted fluctuations (off course, a small capacitor at the controller analogue input would help smooth out any noise).
.
So I'm interested to hear other peoples thoughts.
