My 6HC seems to think I have a CAN connected which I do not

I have been just moving the x axis and pushing the switch manually so if it failed it would not cause any damage

T3P3Tony

@darylprice from your image it looks like the following:

IO3: connections in 5V, out,gnd, in
IO6: io6.in and GND
IO8: io8.in and GND

From config.g

M574 X2 P"io8.in" S1 ; configure X axis endstop
M574 Y2 P"io6.in" S1 ; configure Y axis endstop

Which on first inspection looks correct.

You can check if the endstops trigger sending M119 when they are triggered and untriggered. E.g, here is an example with the Y endstop:

@T3P3Tony
I get the samething. When I press Y endstop I get Y: at max stop, same with X.
I will return 1100am PST US

T3P3Tony

@darylprice

With the Y axis centered so a 200 mm move will not make it travel to far
try entering the following in the console, what happens:

G91
G1 H1 Y200
G90

During the G1 move try pressing Y endstop immediately and see if it stops. Does the axis move in the correct direction as well? if it does then try the full homing move:

G28 Y

and report exactly what happens.

It may help to work though the documentation here and further:

@T3P3Tony
Thanks, I will give this a try as soon as I get back to my shop.

I'll just add that it appears you're using the wrong connectors for the board, could be creating some connection issues.

darylprice

@T3P3Tony

That wroked great! Thank you, I will try the others

@T3P3Tony
I am now having issues trying to get the BLTouch functioning.
When I start the system up the probe kicks out twice and the LED stays on.
M119
Endstops - X: not stopped, Y: not stopped, Z: no endstop, z: no endstop, Z probe: not stopped.

Let me know if you see anything incorrect

chrishamm

@darylprice That's normal for a BLTouch. It's in error state if it starts blinking.

darylprice

@chrishamm
It is not blinking it just stays on until I pull the probe out

darylprice

@chrishamm
I see what you are saying. Is there any test codes I can use so it does not jamb into my base plate. Currently if I try a G30 it just says it is already triggered

chrishamm

@darylprice That's normal.

chrishamm

@darylprice You can send M401 and check if the pin drops out, it should be pulled back in when you send M402. Once you push the pin in, the Z probe reading should go to 1000, if it doesn't, you probably have a wrong input port selected or a wiring issue.

T3P3Tony

@darylprice have you worked through the documentation here:
https://docs.duet3d.com/en/User_manual/Connecting_hardware/Z_probe_BLTouch

and:
https://docs.duet3d.com/User_manual/Troubleshooting/BLTouch_troubleshooting

chrishamm

@darylprice Also your servo pin is inverted (see the ! before the port name in M950 S0 C"!io4.out" ; create servo #0 for BLtouch). That shouldn't be there.

darylprice

@T3P3Tony
Yes I have, I am trying to understand it all. I am using an original BLTouch version 3.1.

darylprice

@chrishamm @T3P3Tony
I have put the Black and Brown wires together since they are both grounds

darylprice

@chrishamm
I found that the P value in the M280 P? S10 command does not want the P9 (for a BLTouch probe), but a P0. It works now with that. I found that on the BLTouch web site

dc42

@darylprice the correct P value to use in the M280 command is the value you used for S in the M950 command to assign the servo pin.
