Issues after prime

Should I reset the toolboard?
By pressing both buttons on the toolboard when starting.
Reload the board firmware and then test it again?
After install the Bus change to 20.

Thanks for testing in standalone mode. Before you do anything to the toolboard, let's let @dc42 have a look and see what he thinks.

Heartleander81

@phaedrux

Ok.

@heartleander81 said in Isusses after prime:

That Video is with a another Purge line.

There is with step lost on X and Y. The print must start on the middle on x150 Y150 but is in the left back corner.

Please can you provide the start of the GCode file that you were printing when you recorded this video.

I suspect that a firmware issue is causing this behaviour.

Unfortunately, I no longer have the file from the print. Do you mean the purge line in the startup code?

Thanks for your Help.

@heartleander81 thanks, to try to reproduce this I also need the contents of macros startGCode and endGcode. [Edit: I see that you have already provided startGcode, so I will try to reproduce it.

@heartleander81 thanks! Do you have any tool change files on your system?

Heartleander81

@dc42 no I don't have tool change file. The tool Board 1lc 1v1 is direkt conected to the duet6 6hc Board.

Heartleander81

@dc42 in the last 2 file is only write M116 P0

I don't see any problem. Does this cause the problem on your machine? Please note, I have modified it to do cold extrusion because my bench setup doesn't have any heaters connected. The Y movement shortly after the extruder prime move is quite fast (F12600), but is OK on my system after I increased the motor current.

I have put a single M116 P0 command n my tpre0.g and tpst0.g files, although of course it does nothing because I am not turning on any heaters.

Heartleander81

@dc42
yes it is my printer. After the conversion to the tool board, the error came after about 2 weeks. Then suddenly the error was gone for 2 prints and now it is permanent.

I was able to observe once in the DWC that the extruder, although it is set to M83, turned from the 100mm extrusion to 0 and again to 100mm and then to 99.4mm built at the point where the retract G1 E-0.600 F1200 is, followed by the G1 XY Move. I'm trying to make a video of the DWC and extruder.

Heartleander81

Ok my camera is to slow. I dount know what that is.

when I delete the first retract G1 E-0.600 F1200 the error is gone. But this is created by the slicer and I cannot prevent this.

Just to be sure what slicer are you using?

@fcwilt Simplify3D . But 6 Montag runs All normal. And one of another Day was that problem

Well you can use a Post Processing command entered at the bottom of the Scripts page of S3D to remove that G1 command if you wish.

{STRIP "G1 E-0.600 F1200"}

@fcwilt but then all retract is delet G1 E-0.600 F1200 is my Filament retract

Phaedrux

I wonder if the fast travel speeds are part of the issue? Have you checked your pulleys for a loose grub screw? With the high speed, accel, and jerk values maybe something is slipping?

Have you tried tamer values?

Heartleander81

@phaedrux
Good point.
But I did that last week on the basis of maintenance when the error was pending.
This is still quite harmless for the design of the printer.
Others drive the printer with 6-8k acceleration and 300-400mm / s movement

The pulleyes All New.

I have test with M906 X1350 and Y1350.
My stepper have 1,7A Max.
And 60mm high.

Phaedrux

Can you enter your motor values and settings into this EMF calculator and see if maybe we're in the range where back emf becomes an issue.
