> I have an 8khz timer running on the tach Yeah... the way I've got my preliminary tach implementation setup; it only calls the ISR for pin change events (which...

S should always control the spindle; however there are other designations that could be used. Both of those pins are on Timer 2; which is being used for the 976hz...

I'll also add this. It will only be present when there is an override menu option available; and will only affect overrides that are menu-driven, not potentiometer driven.

Nice work. 👍 Using the RAMPS board provides convenient connection points for the UI components. I think you'd end up doing a bunch more wiring trying to avoid using the...

_**WARNING!!!**_ I just spotted an error in the Wiring Overview that I had up on the wiki... the 5v and ground pins were reversed on the keypad connector (RAMPS Aux...

Most of the ICs are for buffering & level shifting. There is one RS485 driver on the board; one i2c port expander which connects to a 74HCT245 buffer (intended to...

Well, this is annoying. I'm not sure how I managed to do it, but the pinouts for the connectors that go to the LCD/SD/Encoder knob PCB are wrong... half of...

I'm not sure I understand... You are saying cycle start needs USE_UI_ENCODER_B and USE_UI_ENCODER_B_ISR turned on to work?

@qulet -- do you have a link to any documentation on that board? I found the Aliexpress page where it's sold, but it didn't seem to have very much information...

The photos don't seem to indicate anything more than some buffering logic - 74HC245 - and some optocouplers, and a relay. I think it really is just a generic parallel...
