My 6HC seems to think I have a CAN connected which I do not
-
@dc42 @Phaedrux
The following is my new config.g.
After installing this, the only function I have is x,y,and z movements. No endstops, BLtouch does not work. I do not have any sensors or heaters attached yet. I am trying to get my endstops to work.
I am beginning to think I have a bad board. If I let the machine run for 30 minutes, just setting the CAN errors raise to over 30 million.
I will be away for two hours.; Configuration file for RepRapFirmware on Duet 3 Main Board 6HC

@darylprice can you post a photo of your wiring for each endstop please?
-
This shows the two wires forthe micro switches for X and Y
The other side is the BLTouch. -
@darylprice said in My 6HC seems to think I have a CAN connected which I do not:
If I let the machine run for 30 minutes, just setting the CAN errors raise to over 30 million.
You're still getting CAN errors with the new config.g?
Can you share your homing files? homex.g homey.g homez.g homeall.g
How are you testing the endstops?
-
As dc42 already mentioned the can errors are not significant because you do not have any can devices.
-

@T3P3Tony
I have been just moving the x axis and pushing the switch manually so if it failed it would not cause any damage -
@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 GNDFrom config.g
M574 X2 P"io8.in" S1 ; configure X axis endstop
M574 Y2 P"io6.in" S1 ; configure Y axis endstopWhich 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 -
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 G90During 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 Yand 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.
-
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.

@darylprice That's normal for a BLTouch. It's in error state if it starts blinking.
-
@chrishamm
It is not blinking it just stays on until I pull the probe out -
@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 -
@darylprice That's normal.
-
@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.

@darylprice have you worked through the documentation here:
