azteeg x5 smoothie Very odd endstop issue

[M1T0s1s]

O.K. heres the deal I have an azteeg x5 on a custom built delta and I am using repetier, the endstops are not registering correctly. The alpha endstop works fine, but the beta and gamma endstop will only register if both are pressed together. ie.. beta by itself = 0, gamma by itself = 0, beta+gamma = beta=1 and gamma=1. This is driving me crazy!! I have checked them all with multimeter and the endstops are mechanically fine. They are connected as NC. Here is my config.txt, I am figuring it is somewhere in here.

You need to enable the endstop's:

Configuration

The config settings for Endstops are as follows….

endstops_enable - set to true to enable, false to disable
Where NNN is alpha, beta or gamma

NNN_min_endstop - the pin number of the min endstop (or set to NC if not used)
NNN_max_endstop - the pin number of the max endstop (or set to NC if not used) Only one of these can be used for homing
NNN_homing_direction - set to home_to_max to use the max endstops and home in the positive axis direction, set to home_to_min to home to the min endstop and move in the negative axis direction
NNN_min - if homing to min then set the value of the axis when the endstop is hit (eg 0)
NNN_max - if homing to max then set the value of the axis when the endstop is hit (eg 430). NOTE deltas use this to set the cartesian coords when at home, ie 0,0,430
NNN_fast_homing_rate_mm_s - the speed in mm/second that the axis moves towards the endstop (eg 100)
NNN_slow_homing_rate_mm_s - the speed in mm/second the the axis moves away then back towards the endstop after hitting it (eg 50)
NNN_homing_retract_mm - the distance in mm that the axis backs off the endstop when it first hits it (eg 5), Also backs off this amount after homing when limit switches are enabled. This MUST be enough to untrigger the endstop.
endstop_debounce_count - if the endstops are noisy mechanical switches this will debounce them
Use M119 to show the status of the configured endstops, if an endstop is not connected the pin should be set to nc

Example of end stop config:

# Endstops
endstops_enable true # the endstop module is enabled by default and can be disabled here
delta_homing true # forces all three axis to home a the same time regardless of what is specified in G28
alpha_max_endstop 1.24^ #
alpha_homing_direction home_to_max # or set to home_to_max and set alpha_max
alpha_min 0 # this gets loaded after homing when home_to_min is set
alpha_max 0 # this gets loaded after homing when home_to_max is set
beta_max_endstop 1.26^ #
beta_homing_direction home_to_max #
beta_min 0 #
beta_max 0 #
gamma_max_endstop 1.28^ #

thanks for the reply, but I have all that in the config.txt file. its actually just past the spindle control section of the file. I put a gap so it was easier for me to find quickly while I was editing it, so that might have looked like the end of the file in the post.

I was getting some trouble with the z-endstop. The wiring must be a little off, wiggling the wires can cause a disconnection / reconnection.

Here's my config file: http://pastebin.com/7W0S0LjE" onclick="window.open(this.href);return false;

So I rewired the switches to NO, just so they are exactly as the wiring diagram shows on the panucutt website. So now it acts a little different, instead of only acting when both are depressed they both act when only one is depressed. The X endstop works fine, but the Y and Z appear to work as one. ie... when Y alone is depressed both Y and Z trigger, when Z alone is depressed both Y and Z are triggered. I have tried every config I can think of, NO NC ie.. 1.24, 1.24^, 1.24^!, I have the latest firmware and config file.

[Broose]

Its acting like the Y and Z endstop signal lines are tied together. I suppose its possible there is a problem on the board. One thing you could try just to see if you can get the thing going is to swap the Z signal line to one of the inputs on EXP1 or EXP2 (e.g. 1.22), then change the config file from:

gamma_max_endstop 1.28^
to
gamma_max_endstop 1.22^

With Z not hooked up to its normal endstop input, then Y (normally closed) should also work correctly.

Also- you probably first should just make sure there is no way the two endstop signal inputs are shorted together in the wiring.

Thanks! I followed the traces under a magnifying glass and found a solder bridge on one of the surface mount chips for the endstops. I tried to break the bridge with a needle under my microscope but it still does not work. So i disabled the z-probe and used that as one of the endstops and it is working now. I will contact panucatt and see what to do, but for now I can start screwing around!!

I changed my hot end for a different one. Now my endstops are not working again. It's usually 1 or 2 would not home because they are stuck closed on the Smoothieboard.

Now it's worse, 2 are stuck HIGH and one is stuck LOW so it just keeps chewing up the belt.

The problem of what works and what doesn't seems to be affected by moving the skates by hand. Maybe it's setting state somewhere on the Smoothieboard with the power created?

I was able to use the min endstop ports for the max endstop. In the config file: 1.25 -> 1.26, 1.27 -> 1.28, 1.29 -> 1.30

Other way around, actually. I think you have to lower each number instead of raise them.

Endstop X MIN X MAX Y MIN Y MAX Z MIN Z MAX

Pin name 1.24 1.25 1.26 1.27 1.28 1.29
