So I am well on my way to getting the machine set-up but have run into an issue with one of my end stops that I can seem to figure out.
I have been working through the commissioning steps and am stuck at the end-stop portion. My X and Z end stops appear to function correctly during homing but I noticed some odd issues when the machine hit the Y-axis end-stop first. In testing the end stops with the M119 gcode I noted that the X and Z endstops register correctly via M119 but not the Y-axis stop. When the Y-axis stop is depressed, the machine registers that all three endstops are hit. Once removed, all end-stops register as not touched. I've went over my config a few times and changed IO ports but cannot get it sorted. Another thing I noticed during this testing is that the LED's on the end stops on the X and Z axes illuminate when pressed but the Y end-stop does not. I checked the wiring on the Y axis and even re-crimped the connectors.
My current config.g is below. Any advice or help is very much appreciated!

I also tried to get the End-Stop add-in working but couldn't figure out what needs to be contained within the zip package. All my attempts ended with either nothing happening or a manifest error.
Secondly, my stepper motors are a bit noisy under certain conditions. The symptoms are below:
- The X and Y-axis steppers sound pretty good when moving.
- As soon as I do any movements and the steppers stop moving I have a nasty hum/whining during idle.
- When the Z axis is moving it sounds horrible kind of like a soft grinding.
The steppers are configured based on other people's configs for the same printer (Flashforge Creator Pro).
I am looking for some advice on tuning these steppers better.
Thanks in advance!
