Troubleshooting:
My endstops aren’t working properly
The first thing we need to do is make sure the endstops are wired correctly and plugged into
the electronics in the correct place, see page 17 for the wiring diagram. NOTE: the Blue
wires should all be connected to the S Row, the Black wires connected to the - Row and the
+ Row will not be connected to a wire. NC on the switch should be connected to the Blue
wire, C should be connected to the Black wire and NO will not be used.
Next we will check to see if they are working, to do this start pronterface and
connect to your printer, in the bottom right corner of the screen you will see a
text box and send button. Make sure none of your Endstops are triggered then
type M119 in the Text box and Click the Send button, in your box above the send
button you should see something like picture P1.
Next move your heat bed all the way to the front so it triggers the Y endstop, type
M119 in the box and click send, you should see something like P2. If it doesn’t
look like P2 double check the wiring of your Y endstop on page 17.
Next move your Hot end all the way to the right so the X endstop is triggered,
type M119 in the box and click send, you should now see somthing like P3. If it
doesn’t look like P3 double check the wiring of your X endstop on page 17.
Next we will check to see if your Z endstop works, you can either manually
press your Z endstop switch or turn your Z motors until they hit the Z endstop.
Type M119 in the box and click send, you should now see somehting like P4. If
it doesn’t look like P4 double check the wiring of your Z endstop on page 17.
If any of your endstops went from Open to triggered in the Z_Max, Y_Max or X_Max make
sure you have that endstop plugged into the correct spot on the RAMPS. If you had one
endstop not do anything you can plug it into another spot then run the M119 command again
to see if it works, if it still doesn’t plug a known working endstop into the original port that
wasn’t working, if the known good endstop works we know we have a problem with the
endstop or its wiring, if the known good endstop doesn’t work please contact Maker Farm
for more instructions.
Also the endstops will only work when you press the Home button for all Axis or for each
individual axis, if you press the + or - the firmware is set to not use the endstops.
