Hi,
I have zero experience with CNC in general.
I have 3 axis gantry connected to this controller: ( https://buildyourcnc.com/item/electronicsAndMotors-electronic-component-breakout-Mach3-USB-Board (https://buildyourcnc.com/item/electronicsAndMotors-electronic-component-breakout-Mach3-USB-Board) )
I'm using Mach3 to operate this. I managed to set up soft limits and homing and now I'm really struggling to set up the physical sensors.
Here are my problems:
1. The controller has 4 inputs. I can connect 3 limit switches to a single input (one for each axis). OK so far.
The seller suggest to connect all 3 home switches (which are limit switches as well) to another input. I don't understand how homing can work this way. once one of the home switches is triggered, the rest are irrelevant in this configuration. What am i missing?
3. it seems the limit switch triggers emergency stop that requires Reset of the system in mach3 program. However reset cannot be done until the limit switch is released. but i cannot move until I reset the system. So i'm in deadlock. what am i missing here?
2. in Mach3: Config -> Ports & Pins -> Input Signals -> EStop is set to Input1 and cannot be disabled after saving the configuration the EStop remains enabled.
Thank you in advance
