1HCL position failure home position G-code

[OwenD]

@supertb1
move.axes[n] is an object model array.
There will be one array item for each configured axis.
move.axes[0].machinePosition simply reports the position of the X axis.
Likewise the others report the position of the Y & Z axis at the time the macro was run.
So unless you have 52 axes, then your example would give an error.

Perhaps start with something like

;driver-stall.g
G60 S3 ; save position to slot 3
G28 X Y ; home X & Y
G1 R3 X0 Y0 Z0 ; Move back to saved position

You can test it by sending M957 to simulate a fault (or deliberately cause a stall by hand)
M957 E"driver-stall" D1

@OwenD P50-P51 are my 1HCL CANBUS drive addresses.. the question was weather or not I needed to put that information in place of the mainboard driver addresses or if the line codes as you have them listed would work as they are... see what I am looking for is someone who knows the code architecture well enough on MB6HC that I can create whatever directory needed in the .sys and then dump the example in there with the correct format to keep my system from crashing... what can I give you or @dc42 that can help me with that... as I have stated before I am a noob when it comes to this issue... I have no formal education on this system, everything has been trial and error..lol... I just want my system to return to the home position when it runs into a position failure like it did 5 or 6 updates ago

@supertb1
You have been provided multiple links to the relevant documentation and have been given examples of possible code and how to test it.
Until you read the documentation and apply the examples then I can't help any further as I don't have an identical system.

@OwenD Ok, thank you for your help on this.. I will give it a shot and get back to you.

[supertb1]

@OwenD Hello, I made a file (driver-stall.g) in my .sys directory and dropped the example in there. then I entered M957 E"driver-stall" D1 in my command line and it returned "M957 E"driver-stall" D1
Warning: Driver 0.1". now it does not recognize my tool, it immediately causes my X axis to fail to maintain position. so the settings in the stall file need to be adjusted. Ok I have a Duet 3 6HC, "2" 1HCL boards (P50,P51) X and Y respectively. "2" Z axis motors (0,1) on the main board. The extruder is on (4). do I need to place the physical address of the drives that are on the boards inside the [0] on the command lines for this driver stall.g and how would the Z axis look on the command line? move.axes[0,1]? I tried to enter the actual board addresses in the command lines and it still does not recognize the tool. ok.. so I don't think your model as it is will work for my setup. I tried your ";driver-stall.gG60 S3 ; save position to slot 3G28 X Y ; home X & YG1 R3 X0 Y0 Z0 ; Move back to saved position" line and it causes my machine to forget the X and Z axis home at the start of my print end the program and then home the X and Z axis so that is not going to work either. What changes need to be made to these examples to help make them work for my applications? what information can I give to you to help with this process?

[supertb1]

@dc42 you know what would make this all alot easier is if I could simply change the default process from "Pause print without running pause.g and inform user via message box" to "Pause print using pause.g and inform user via message box" How do I do that? Or better yet, can I get a firmware update that has that change in it?

[OwenD]

@supertb1
I cannot work out exactly what you are doing by your answers.
You appear to be mixing all sorts of things together.

You need to read and understand the documentation given to you so that you can grasp the way the firmware works.
There are two possible work flows with any of the events.
One will happen if you have not created a macro to handle the event and the other will happen if you have created a macro to handle it

So in the case of a DRIVER ERROR, then if there is no file in the/sys directory called driver-error.g, then the firmware will pause the print without running pause.g and a message box will appear. It will just stop.
If there IS a file called driver-error.g in the /sys directory, then you determine what happens by the contents of your macro.

The parameters mentioned are NOT parameters that you send.
They are parameters that you can access within your macro so that you can have one macro but take different actions depending where the fault was.
So for example in my driver-error.g macro I could put

echo "Fault on driver" ^ param.D

and it would report which driver number the error happened on.

You are going to need to post the following files.
config.g
driver-error.g
driver-stall.g
homeall.g
homex.g
homey.g
pause.g

When you post them, please ensure that you use the </> button so the contents appear is a code box like this

code box

This will make them readable.

Also post the firmware version you are using on all attached boards, by sending
M115 B0
M115 B1
M115 B2
one command at a time from the console.

After all that we will need to know exactly what problem(s) you are trying to fix?
There is no point for example focusing on a driver-stall.g file, if your problem is actually a driver error, and not a stall.

Issue at hand: when my printer fails to maintain position or the X-Y steppers stalls I want it to move my print head to home position Z+5 like it used to do.

I meant for you to put each file in its own code block so we could know exactly what you are working with.
I will try to separate and comment as I can.

Again, you are trying to go to X0 Y0
What happens when you force a driver to stall?
Does the machine move to X0 Y0?
Note, that you have not re-homed the axis, so it may move to where it "thinks" X0 Y0 is, but if it had already skipped many steps then it may end up somewhere entirely different.
EDIT: I don't know exactly how running closed loop will fit into this. It's possible the motor can stall and not lose track of position. That's the whole idea I guess.

I don't know enough about the 1HCL boards to interpret these errors.

Issue at hand: when my printer fails to maintain position or the X-Y steppers stalls I want it to move my print head to home position Z+5 like it used to do.

Again, what does it do now when there is a stall.
"Like it used to"?
When did it do that?
What has changed since then? e.g. Firmware? From what version to what version?

[OwenD]

@supertb1
In addition to above, I suggest you put the following lines at the start of your diver-error.g and driver-stall.g files.
This will help identify which is being called and what the fault is.
This is because the macro called will be dependent on whether the loss of position is greater than or less than the E parameter in your M569.1 for that axis.

;driver-stall.g
echo "Driver stall has occurred"
echo param.S      ; send error message to console

;driver-error.g
echo "Driver error has occurred"
echo param.S     ; send error message to console

EDIT.
Also the code for the firmware on the expansion boards should be
M115 B50
M115 B51
You have to send the CAN address for these boards.

in closed loop the machine knows where it is at all times. however if the motor failed or the drive board "1HC" failed I am sure the system wouldn't function as intended, I have not had this issue yet.

It causes the machine to wait for a count of 2 minutes and then it homes the X axis, then the Z axis, then the X axis again, and then the Z axis again. this feature has never worked correctly while the 1HC boards have been in use. It worked fine when I had the axis drivers on the main board.

"Again, what does it do now when there is a stall.
"Like it used to"?
When did it do that?
What has changed since then? e.g. Firmware? From what version to what version?"
Before 3.0 the system would send the axis back to home on a "failure to maintain position" I believe. it is only been in the last year that I have began to have this problem.

with the stall and error.g files as they are, a manual move from position generates a "Error: attempting to extrude with no tool selected." fault on the PanelDue 7.
Running a simple bed leveling program and causing a stall causes the print head to move toward home but then it raises the print head 5mm and then it goes back out to print... so wierd.

so the drive-error.g and the driver-stall.g will not work as they are currently. But we are getting somewhere, at least it isn't just stopping in the middle of the print anymore.

Are you saying an attempt to move X and Y by say G1 X100 Y100 returns that error?

so the drive-error.g and the driver-stall.g will not work as they are currently. But we are getting somewhere, at least it isn't just stopping in the middle of the print anymore.

So when you run the bed levelling, did you first select a tool and get the extruder up to temp?
In your stall.g and error.g you have simply copied your pause.g

This will make it
move to X0 Y0
raise Z
Retract 10mm
Then return to print job

You can't retract (extrude) without a tool selected!

So it sounds like it's doing what you told it to do.
You must either re-home it to ensure that the position is now correct or pause it if that's what you want.
Any retraction etc should first have a check that a tool is selected and up to temp.

I'll have to leave any behaviour differences in firmware to @DC42

[supertb1]

@OwenD
No what I am saying is that while the system is running a program a manual move from intended path returns the ""Error: attempting to extrude with no tool selected." fault on the PanelDue 7." and then the aforementioned behavior ensues. And no I usually do not preheat the tool, that is in the gcode of the slicer app and yes the overall behaviour of any kind of motor stall of the X-Y axis needs to be "Go to the pause location" IE home Z+5. That is the ultamate goal

[OwenD]

@supertb1
I don't know if there is a language barrier, or if you're being deliberately obtuse.
If you want it to go to X0 Y0 Z+5, then wait, you must tell it that and only that!
I'm afraid I have nothing more to offer you.

[supertb1]

@OwenD
I'm not trying to be anything but 1)most importantly seeking answers to this issue 2)humbled by this experience ...as it is for me to be a little ignorant and learning from someone who obviously knows more about this than I do.
Maybe I do not know the correct responses to your questions which is why I have been asking for a step by step solution to this problem as if maybe everyone who is using MB3 6HC in conjuction with 1HCL boards might be experiencing. I don't know, I can only assume the people over at Duet3d have run into this issue @dc42.
I apologize if maybe I have offended anyone in this conversation. I hope that through your networks/groups a simple solution can be found so that in the future anyone with this issue can find a solution by simply looking and finding it here.

Most likely your pause.g file has a retraction command in it, such as G1 E-5. You can suppress that message by making the retraction conditonal:

if state.currentTool >= 0
  G1 E-5

Similarly for the reprime command in resume.g.

[supertb1]

@OwenD
Hey I wanted to thank one of my friends who knows this system pretty well, he suggested that i kept it simple and only used one command to solve my problem that I have been working to solve and this is what he came up with.

echo param.S     ; send error message to console
;M83            ; relative extruder moves
;G1 E-10 F3600  ; retract 10mm of filament

Thanks for your help again @OwenD

@dc42 Please consider this issue closed, I can't wait for Mr. Rosario's Closed loop tuner pluggin to be available. The guy is so good at this platform and well worth the investment..

@supertb1 thanks, I'll mark it as solved then.
