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

T3P3Tony

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:
https://docs.duet3d.com/en/How_to_guides/Commissioning#h-8-check-endstops

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

elmoret

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

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.

darylprice

@dc42 @chrishamm @T3P3Tony @Phaedrux
I want to personally thank all of you for helping me. I know you have to deal with us newbies all the time.
Hope I listed all of the people who helped. I am sure I will be reaching out again.
Thanks Daryl

@dc42
Quick question. What is the safest way to shutdown my printer before I cut the power?
Daryl

jay_s_uk

@darylprice just pull the power. theres no shutdown needed

gloomyandy

@darylprice Are you running in SBC mode or standalone?
