So I just reworked my MPCNC (lowered build height and while at it printed the new feets). I also attached endstops to it, although I still don’t understand the advantage of this.
Yes, I do run powered endstops. I have none of those 2-wires, non-powered endstops around.
Not really suprising, I now experience cross-talking on the wires. Estlcam tells me my endstops are triggering all the time, although my endstops are not even connected @ramps (but the cables are connected at the endstops)
As you can see in the picture, I have unshielded cables for both steppers and the endstops, running through the conduit and also through the drag chains (I know…). Cables are also about 2-3m long :). Will pull the plug on the endstop next and check if Estlcam still reports triggered endstops (when endstops are NOT hit).
Its strange because Repetier (when using the latest dual-endstop firmware) never shows a false triggered endstop.
As I said, I don’t really understand how endstops are helping for the MPCNC here at all (yes, I have read the related blogging article and also saw the video - serveral times), so another option is to just remove the endstops. I’m fairly certain I can get this machine squared. If anything, I would like to have endstops to have a defined zero/homing position, not for making the machine square.
Whats your take on this? Ever experienced cable noise? Any suggestions (other than: replace cables with shielded ones, remove endstops, or something like this https://hackaday.com/2014/03/07/solving-endstop-woes-with-a-simple-analog-filter/)?
