It appears that the first attempt failed

Well . . . I guess I'm in shock.

I don't know how to use DWC, but I did try to home X.

The racket caused me to turn off the machine right after I checked the print head to see if it was stuck.

Hence the title of this post.

I can hear the power supply running. The front fan on the print head is working. Green, green, red, red, blue, then a flashing red led, that's what I'm seeing.

And that's that.

It's best to test each bit of hardware, one test at a time.

• verify endstop operation by monitoring the state of each endstop in the object model viewer, with each endstop switch operated by hand.

• verify stepper operation by enabling movement when not homed (issue M564 H0) and the jog each stepper in very small amounts from the DWC

Once you know that endstop sensors and steppers are working you can try jogging each stepper toward the endstop for that axis and verify the endstop is operated correctly before jogging into the end of the axis.

You can, if desired, reduce the stepper current for these tests using M913.

You can then check your homing code by issuing a G1 H1 command, for each axis, set for a short distance and at a slow speed to verify that the command moves toward the axis endstop as expected.

Once that is working correctly you can go back and issue the same G1 H1 commands, but for a long enough distance to reach the endstop sensor. When the endstop sensor is operated the move should immediately stop.

Hopefully this is enough to give you an idea of how to proceed.

@fcwilt where us, or what does the "object model viewer" look like so I can find it.

Drat. I'm not at home and don't have access to the DWC so I could take a screen shot.

It's a optional feature that is included with the firmware but you have to start it.

It's under the item on the left titled "Plug-Ins" (I think) and as I recall there are two tabs for two different kinds of plugs-ins.

See if you can find that and look for one mentioning object model browser or something similar.

@fcwilt I’ll give it a try.

Thanks for helping me.

@fcwilt I found it. Listed in the plug-ins.

I looked at it. Meaningless to me. Could you try to describe what it does? How I might try to use it? I guess I was expecting a model. But it’s lists. How are lists, how do lists become models?

The object model is organize and displayed as a tree structure.

Endstops are treated as sensors which as I recall is a top-level item. Select that and you should be able to see endstops, which you can drill-down into and locate each endstop by number, 0 is the X axis, 1 is the Y axis, 2 is the Z axis.

@Corlissmedia

It doesn't do anything, it's a repository for settings and status information.

You can use the nodes to find information - and the node name in macros to retrieve that information.

For example, in the "global" node it will show you the current values of the global variables, like these in my setup:

...and the status of the three end stops:

There is also a guidance document here.

By the way, I don't think the topic title is appropriate.

@corlissmedia there’s a whole guide for commissioning (ie check everything is working). https://docs.duet3d.com/en/How_to_guides/Commissioning

Specifically for testing endstops (3 ways covered, on three tabs) https://docs.duet3d.com/en/How_to_guides/Commissioning#h-7-check-endstops

But PLEASE follow the whole guide. It will explain a lot!

I agree.

@Corlissmedia please title your threads more appropriately for this forum.

FYI to change the title of a forum thread, edit the first post of the thread. This can only be done by the thread starter (ie the first post to a new thread) or an admin.

I have renamed the thread and unlocked it.
