Dumbfounded ! Firmware bug in 3.4 beta 6?

[GeneRisi]

I am using Simplify3d and firmware 3.4 beta 6. I have set the perimeter tool as Tool 1 and the infill tool as Tool 0. The infill does not line up with the perimeter. The tools have different offsets in config.g (and it's as if the offset is not applied when the tool is switched).

When I use Tool 0 as the perimeter and Tool 1 as the infill, it works! I edit the gcode by hand to switch the T0 and T1 lines and that's the only difference. Is this a firmware bug? I could fill this post with config.g, the Tpre, Tpost and Tfree for both tools and the gcode but I don't know if it will suggest anything since the order of the tools makes the difference.

Please advise... thanks!

@dc42 I found the problem.

When tool T1 was being returned, the Y "parking" coordinate was off by 1 mm. The tool parking location didn't budge but the firmware thought that the tool location was 1mm beyond where it actually was. The machine is a corexy (E3D), so even though only the Y coordinate was off, I suspect it affected both the x and y location from the the firmware's perspective.

It might not hurt to share the config files to let us better try and reproduce.

You could also try reverting versions and seeing when the behaviour started happening.

[Phaedrux]

I think you may be affected by this change in B6

Upgrade notes:

Important! After changing tool, RRF no longer moves the new tool head to the coordinates at which the old tool head was at when the Tn command was actioned. In most situations this should not matter, because GCode generators usually generate commands to move to the correct XYZ position after generating a Tn command. Usually, they restore XY before Z. However, Cura does it the other way round, which risks dragging the tool head across the print. Therefore when using Cura, or in any other situations in which you want to restore the old behaviour, we suggest you add command G1 R2 X0 Y0 Z2 Fxxx followed by G1 R2 Z0 Fxxx to the end of your tpost#.g files, if you don't already use those or similar commands.

@phaedrux I was restoring Z but not X and Y because the next G1 command would change the position of the tool anyway, so 1 line might not get drawn properly but the following lines should be ok as long as the G1 command included x and Y coordinates. Right?

[Phaedrux]

I'm not sure, but Putting G1 R1 X0 Y0 Z0 at the end of the tpost#.g file would fix that if it is the issue you're having.

[GeneRisi]

@phaedrux I'll try it

[GeneRisi]

@phaedrux I think you meant to say R2 and not R1, correct?

@phaedrux I think you meant to say R2 and not R1, correct?

Correct, it should be R2. The mistake is actually mine, not the fault of @Phaedrux !

[GeneRisi]

@phaedrux "G1 R2 ..." did not fix the problem. Maybe a firmware issue...

I also tried starting with T3 and then using T0 and that worked correctly, so two sequences worked T0, T1 and T3,T0. T1,T0 does not work as expected.

[A Former User]

@generisi
I have something similar but till now no idea what's wrong.
How about changing tool outside the print?

[GeneRisi]

@gruna-studio It takes a fair amount of gcode to change the tools. Each tool has its own unique set of offsets from the system coordinates which the firmware manages.

what are the differences between those free, pre and post files?

[GeneRisi]

@t3p3tony Hi Tony - I have included those files in the post previously. I can't see a difference that would explain it.

G29 Q2

These are wrong - Should be G29 S1/S2 - although i don't think that's the cause of the issue.

I assume you now have :

G1 R2 X0 Y0 Z2
G1 R2 Z0

at the end of all the tpost#.g files?

@generisi said in Dumbfounded ! Firmware bug in 3.4 beta 6?:

can i check T0 -> T1 works but T1 -> T0 does not work? What if you just command the tool changes through the console sending:
T-1
T0
G1 X100 Y100 Z0
T1
G1 X100 Y100 Z0
T0
G1 X100 Y100 Z0
..etc

repeatedly does the pickup point or the position X100 Y100 Z0 differ between the tools?

[GeneRisi]

@t3p3tony Hi Tony - I have my own "mesh.g" macro that allows me to also use "Q1" and "Q2" as inputs. I use the macro to check that the bed mesh in use has been created after the most recent system reset and is not being used if it was created some time before the most recent reset.

;       global.freshMesh set to false in config.g
;
var qVal = 0
if exists(param.Q)
	set var.qVal = param.Q
if var.qVal = 0
	if !move.axes[0].homed | !move.axes[1].homed | !move.axes[2].homed

Also, is there a reason why you did not combine the two "G1 R2 ..." commands into a single command?

I will try your suggestion. Thanks!

ok i did not realise that - nice use case!

restoring it in the way I showed, with some Z lift first, is what we recommend for most use cases as it means the last axis to move into position will be Z, so there is less change of the tool dragging across the top of the print as the position is restored.

[GeneRisi]

@generisi There are either 2 or 3 contact spots checked very unscientifically with double stick tape on the bed when alternating T1, T0, T1, T0, ...
