Tool Change: Moving in axis without calling them

smoki3 · 13 Dec 2019, 11:22

@Danal
no they are not coded. Just the lift of the nozzle before the tool change starts. Anything else is due to the fact that there is an issue after the tfree.g script with calculating the position.

If you do a T-1 and then a T1 you get a different behaviour. Then you dont have the Z-movement even though are running exactly the same scripts.

When you go back to 2.02 there you see you dont have this movements.

I found this comment in the GCodes.cpp, which sound a bit like this bug @dc42

 else if (rp != nullptr)
			{
				currentUserPosition[axis] = moveArg + rp->moveCoords[axis];
				// When a restore point is being used (G1 R parameter) then we used to set any coordinates that were not mentioned to the restore point values.
				// But that causes issues for tool change on IDEX machines because we end up restoring the U axis when we shouldn't.
				// So we no longer do that, and the user must mention any axes that he wants restored e.g. G1 R2 X0 Y0.
			}

Very interesting. I will keep that in mind as I research this further.

I can't run any version of 2; I am on Duet 3 hardware.

That change was introduced way back in firmware 1.19.

I think the change in behaviour must be connected with this change, in the upgrade notes for 2.03:

Tool changers, IDEX printers and similar using tfree#.g and tpost#.g files: tool offsets are now applied within the tfree#.g and tpost#.g macros (but not in the tpre#.g file because no tool is selected at that point).

Perhaps there is a G1 command in the tfree or tpost file that needs to be corrected for tool offset, or else a G53 prefix added?

No I don't think so!

@dc42

I made some videos:

First I have just clicked on T0 to pick it up:

https://photos.app.goo.gl/ipCKj1bHJ15dw8NKA

After this I picked up T1 by clicking on it in DWC:

https://photos.app.goo.gl/yqMHUWQt5n7gYiPX6

Last on I deactivated T1 by click again on T1 in DWC:

https://photos.app.goo.gl/Nnn5NxX9C4Ph9WFx5

So do you see this wired diagonal move with XY axis and Z Axis in the second video?

Danal · 13 Dec 2019, 17:17

I understand why offsets are/aren't applied. They correlate to the "what tool number is currently mounted" status of the printer.

Therefore, I have G53 in front of the vast majority of the moves, because those moves need to deal with the parking posts in absolute terms.

I'll see if I can reproduce what happens in the above vids.

As you can see in my tpre script I also have G53 in front of every move. That this diagonal move does not exist in the script and only happens if you directly move from T0 to T1 if you do a T0 → T-1 → T1 it does not happen.

But I am not able to see at which coordinates. this diagonal move ends

smoki3 · 13 Dec 2019, 17:55

So I adjusted the tool offset not to this:

 ; Tooloffset
G10 P0 X0.00 Y50 Z0.0                    ; Set tool 0 axis offsets
G10 P1 X0.00 Y0 Z0.0                   ; Set tool 1 axis offsets

Then it looks like this:

https://photos.app.goo.gl/MzJ7iRV5FMb3namx7

As you can see the printer is moving diagonal 50mm in X axis (from the tpre.g) and Y axis (from removing the tool offset). The Z movement is gone because there is not Z tool offset defined.

Normaly it should just release T0 and move just 50mm in X axis as defined in the tpre script.

Please try the firmware at https://www.dropbox.com/sh/3azy1njy3ayjsbp/AACquxr2m00eV568RZg5QG5wa?dl=0. Running the Duet 2 version of this firmware on my tool changer, I don't see any diagonal moves, where as I did when running RRF 2.

Note, currently you cannot downgrade from this firmware via Duet Web Control when running with an attached SBC. That will be fixed shortly. Meanwhile, you can downgrade by running in standalone mode or by using Bossa.

The videos from above already with RRF3. This problem exists since 2.3 equal to RRF. With the tool changer scripts from E3D they bypass this bug because of calling X and Y axis in the first move of the tpre script. But there you can still see the Z axis movement during the first tpre move

smoki3 · 15 Dec 2019, 20:25

@dc42

So tested it again now. It happens exactly the same as you can see on post 25.

If I move the whole tpre script to the tpost and add G53 in front of every G1 then it works fine.

The problem is: The not called axes are moving exactly the distance of the tool offset from the cleared tool instead of just update the coordinates for the not called axes and just move the called axis.

There were the changes in 2.03:

May 25th:

Restore points (created by G60 and created automatically at the start of a pause or a tool change) now have their coordinates stored independently of any workplace offsets. So if you create a restore point and then change the workplace offsets, when you go back to the restore point it will go back to the same machine position regardless of the change in workplace offsets.

and this March 3rd:

-- Tool changers, IDEX printers and similar using tpre#.g and tpost#.g files: tool offsets are now applied within the tpre#.g and tpost#.g macros.

I assume that one of these leads to the bug.

I am trying to get setup to test this with your exact files (except for absolute coordinates of the tool parking, of course).

More later today...

I backed up all my pre/post/free files and copied yours in exactly. I set a Y tool1 offset of 25.

I do not see any diagonal moves occur. T0 T1, T0 T-1 T1, no sequence I've tried produces a diagonal move.

I DO see the final Y coordinate displayed in DWC for T1 jump from 100 to 125, when the T1 sequence ends.

I do not see any diagonal moves occur. T0 T1, T0 T-1 T1, no sequence I've tried produces a diagonal move.

I DO see the final Y coordinate displayed in DWC for T1 jump from 100 to 125, when the T1 sequence ends.

You have to set the tool offset for T0. Best you try it to set the offset for both tool in all 3 axis. It's always from the tool which is clear.

I don't think the movement calculation is different for duet 3 and duet 2.

Here the issue exists and on all the tool changer videos on YouTube you see it as well (moving z axis after tfree)

I will give that a try. I'll just copy your tool offsets exactly.

OK, I have reproduced the diagonal move.

Interestingly enough, I then put messages (m117) and delays (G4) in the tpre1.g file... and the diagonal move WENT AWAY. Very, very, odd.

At this moment, I'm experimenting with delays and similar to find out exactly which command causes the diagonal move.

	else if (rp != nullptr)
	{
	currentUserPosition[axis] = moveArg + rp->moveCoords[axis];
	// When a restore point is being used (G1 R parameter) then we used to set any coordinates that were not mentioned to the restore point values.
	// But that causes issues for tool change on IDEX machines because we end up restoring the U axis when we shouldn't.
	// So we no longer do that, and the user must mention any axes that he wants restored e.g. G1 R2 X0 Y0.
