@Max3D said in CNC Duet 3 DWC Homing button error.:

Does the DWC homing buttons reference my macros?

Yes. Please post the files @jay_s_uk asked for.

@Max3D Your homing files look fine.
If you press the homing buttons once they are homed, they will turn from yellow to blue until the axis rehomes again.

If you press the buttons, does that axis successfully rehome?
I would also not be including M564 H0 in your config file

Max3D · 3 Sept 2020, 06:10

I removed the m564 H0, and reset after saving config.g. Went to dashboard and hit the 'Home All' button then received the pink dialog with the "G28 Error: Homing failed".

Ran the 'Home All' macro successfully with DWC responding with color change to blue on all axes, then hit the 'Home X' DWC button and then received the pink dialog with the "G28 X Error: Homing failed". DWC 'HOME X' button now yellow and the yellow banner stating: "! The following axis is not homed X".

jay_s_uk · 3 Sept 2020, 06:14

Does the x axis move at all when you try to home it?
Have you checked the statuses of your endstops to ensure they show as triggered or not correctly?

Max3D · 3 Sept 2020, 06:16

Nothing on the axis (no stepper movement). Endstops are triggered when homed and not when spindle is in the middle of the bed.

A Former User · 3 Sept 2020, 06:16

homeall.g and g28 x doesn't do the same thing, homeall.g and g28 does.

can you run your homex.g macro without errors?

Max3D · 3 Sept 2020, 06:18

Just ran homex.g macro from the all axes homed position, homex.g ran without error and axis re-homed.

jay_s_uk · 3 Sept 2020, 06:24

@Max3D so what did you do differently than your earlier post at 07:10? as what failed that time seems to have worked this time

Max3D · 3 Sept 2020, 06:32

To try and simplify this... First time I used the Home all button and the homeall.g. Then I used the Home X button followed by the homex.g.

Every time I used the DWC buttons I receive the G28 error dialog box in the lower right of the browser screen with no machine movement.

Every time I use the macros (anyone) the axis homes and the status of the DWC buttons change from yellow to blue or stay blue.

Max3D · 3 Sept 2020, 07:14

Maybe this can help. I recently had to erase the firmware and flash from the RaspPi (mod 4 8gig) with bossac because the new Duet 3 board had some kind of early release bug that would execute the comments in the config,g as code and would not allow the sudo apt get update/upgrade to alter the firmware (currently running latest release downloaded in the last 10 days). I am running the CNC's DWC with monitor and input devices directly connected to the Pi, and not from any laptop connected to my home network.

Phaedrux · 3 Sept 2020, 16:54

Can you send M122 in the gcode console and post the results here?

Also please check the version of DWC from the settings tab.

Firmware and DWC should both be at 3.1.1

G28 = homeall.g = home all button in dwc
G28 x = homex.g = home x button in dwc
etc, etc

When you click the button in the DWC it marks the axis as unhommed and then tries to execute the commands in the macro to rehome. If it fails to do that for some reason you get left with an unhomed axis.

Max3D · 3 Sept 2020, 20:02

As I stated in my last reply. I did a sudo apt get update & upgrade from the RaspPi within the last 10 days. This is a new build. The board had a known firmware bug (beta release 12 or something to that affect) from what I have read here in the forum. The board would not detect the endstops when powered by usb during initial setup either, so I erased the board and then did flashed it with the RaspPi. DWC is at 3.1.1. and below are the diags from the M122. IF the board is glitchy then I need to have it replaced. I can't lose any more time on a bad board...

Please bare with us while we troubleshoot your issue. If we send you a new board, but the problem is in the configuration, we didn't save you any time at all, because no problem was solved.

Now I'm having some difficulty understanding the issue exactly.

You say the endstops are working fine, but trying to home produces an error. How have you verified that the endstops are working if you can't home?

If you go to the machine specific settings tab in DWC where the endstop status is displayed, does the status change when you manually trigger the endstops by hand?

We need to verify that the endstop config is correct.

 ; Endstops
M574 X2 S1 P"!^io0.in"         			; configure active-high endstop for high end on X via pin !^io0.in
M574 Y1 S1 P"!^io1.in"         			; configure active-high endstop for low end on Y via pin !^io1.in
M574 Z2 S1 P"!^io2.in"         			; configure active-high endstop for high end on Z via pin !^io2.in

When you send G28 (or push the home all button in DWC) how much movement do you get? At what point does the error occur?

Also, can you send M98 P"config.g" in the console and report the results here?

Max3D · 3 Sept 2020, 21:37

I am able to home using the macros, All, X, Y, and Z. The steppers start pushing the axes and the homing code executes the bump and rebump in beautiful harmony. When I use the macros the DWC's homing buttons turn from yellow to blue (all is well and dandy).

I can move the spindle around the bed with the buttons on the DWC's dashboard in the "Machine Movement" section using the "(x,y,z)+/-50" on all axes. I can test the soft limits on the axis and will receive an error when I try to go beyond the config.g settings (X=500 Y=400 and Z+70).

Using the macros, I can home an individual axis and then rehome without failure or any error code. When all the axes are homed I can see all the limit switches are lit with a red LED indicating they are triggered. I can go to the "machine specific" section of the DWC and verify that the endstops are triggered. Using the macros, I can rehome all day long without an error and each time the axes will do that beautiful bump and rebump, endstops lit up.

BUT, whenever I try to use the DWC homing buttons (whether they are yellow or blue), I get the cute little pink dialog box with the dreaded "G28 Error: Homing failed" and the button turns yellow; not a peep out of the steppers. I go to the top of the dashboard page and type G28 and hit the send button and I get the same cute little G28 Error: Homing failed; steppers idling. It does not matter which DWC button (or G28 I send from the console) I use, the only thing that happens is the error dialog box (All = G28 Error:, X=G28 X Error:, Y=G28 Y Error:, Z=G28 Z Error:) and the button turns yellow. It is consistent no matter how many times I reboot, power down, or rest the after saving config.g.

Max3D · 3 Sept 2020, 21:45

Sorry... The M98 P"config.g" returns "M98 P"config.g"" in the console.

Phaedrux · 3 Sept 2020, 22:01

Ok then something is not right, because the "macros" are the same thing that DWC uses when you push the buttons.

Where are the macros you are using to home located? They should be in /sys/homeall.g homex. etc

If you are using homing files located anywhere else, they are not in the right place.

G28 = homeall.g = home all button in DWC.

So if G28 and the buttons don't work, then the homing files in the /sys folder are not correct, and whatever macros you are using to home should be moved into the system folder.

Max3D · 4 Sept 2020, 01:21

Well, this was a unique learning experience. I moved the homing files to the "Macros" under the "File Management" a month ago, while dealing with the firmware issue.

I moved them back to the "System" section in the "File Management" menu in the DWC. All is back to normal, if there is such a thing...

Thanks for your help.
