Need Help Configuring EndStops

OK, here is the situation ... I'm using a former Ender-4 frame (board fried) and installing a Einsy Rambo 1.1 board from UltiMachines. My Marlin firmware is 1.1.5 and Arduino IDE is 1.8.5. I am using the pre-configured Marlin firmware by UltiMachines found here. The issue I am having is with the end stops, I have mechanical NC switches(tested with multimeter to make sure they are working). I am using Pronterface to check the endstops with the M19 command. It shows all the switches as Open, but when I test the endstops with one closed, the return does not change, they all still show as open. I'm not sure what I am missing in marlin.

Here are clips of the code from my Config_h file:

//===========================================================================

#define MAX_SOFTWARE_ENDSTOPS


and from the ConfigAdv_h

// @section homing

// If you want endstops to stay on (by default) even when not homing
// enable this option. Override at any time with M120, M121.
#define ENDSTOPS_ALWAYS_ON_DEFAULT

Any clue as to what I am missing?
Any help would be appreciated.

I was looking into this and I see in pins_EINSYRAMBO.h

//
// Limit Switches
//
#define X_MIN_PIN          64 //12
#define X_MAX_PIN          -1
#define Y_MIN_PIN          69 //11
#define Y_MAX_PIN          -1
#define Z_MIN_PIN          68 //10
#define Z_MAX_PIN          -1

So to me it looks like If your using the endstops plugs you should be using 10,11 and 12
But if your using the Trinamic smarts to be endstop free, you use 68,69,64

The Ender-Stein has senses now!!!!

Thanks Dust for spotting that for me, it fixed it perfectly.

I'm not sure how to take advantage of the Trinamic smarts, but that it something I can look into later, lol.

OK, I spoke a little to soon, lol. The X & Z end stops are working, but the Y end stop isn't, and its to do with the board. Continuity checked fine, but I can switch the plugs on X and Y end stops and the same error occurs, I'm wondering if they Y pin is incorrect on the pins_einsyrambo.h? I triple checked to make sure I didn't type in the wrong pin for all of them and I did it correctly.

the circuit diagram also says Y Min endstop is pin 11... [github.com]

That is what I have it set to, but its not working.

OK, so I opened up the original Marlin/Einsy firmware configuration by Ultimachine. Went through it and made all the same changes and uploaded it to the board again. Now everything seems to be working. 'Shakes Head'

Thanks again for the help Dust

I was having the same issue and now the endstops are triggering thanks to the Dust also.

The next problem I am having is that even though they are triggering as shown by M119, they do not stop the movement of any of the axes. Any ideas? I have the same config as previously shown above including configuration-adv.h

Just to add, if I home an axis (through Pronterface) the z-axis rises the correct amount but no other axis then moves.

If it doesnt stop, you have you axis setup badly or enstops configured for the wrong ends of movement

ie If it thinks its moving right and its actually moving left It will only check the right endstop.

So what type of machine is it, and where are your endstop. (I3 clone, core xy, delta?)

It’s a Prusa i3 type that I built a few years ago. I’ve put it back together with the ramps so that I can make some parts for a tslot version that I am building now. Once I get back into the Einsy board if the issue persists i’ll post again.

Can you use the Trinamic smarts as endstops on Core XY machines? I was trying to set them up, but it occured to me that moving either X or Y (or both) means that both the X & Y stepper motors are used. So since both X & Y steppers are always being used to move both X & Y axis how would the steppers feedback be read?

I suspect It could be made to work on coreXY as long as each axis is homed individually. both X and Y steppers would stall at the same time and both would trigger. But the firmware knows it was homing X, so can work it out that x endstop must have been hit.
As long as the Y errors(endstops) is cleared then it can home y

Does this actually work with current firmware? unknown to me....

Yeah, guess I'll be sticking with mechanical end stops for now, lol. Going to make adding the BLTouch interesting though. Those that I've read about attaching it to the Einsy used the Y end stop plug freed up because of the Trinamic's ability to be used to home the axis. Mine isn't free, lol.
