Issues after prime

@phaedrux
Yes that is my startcode

The video start after finish G32.

After the the Purge line goes X to 110 and from ther Point start the slicing Part with G1 E-0.600 F1200 and on the next move to print Point start ist the issuse.
I think I See at dwc Motor E run to Zero and back without 0.6mm
From E100 to E0 to E99.4

My homez is old. I know i must clean it.

Phaedrux

By the way, when using a BLtouch you do not need to use M401/M402 explicitly. The G30 commands will deploy and retract as needed.

The only thing I can think of for the extrusion move is that your E speeds may be a bit aggressive?

M566 X1250.00 Y1250.00 Z200.00 E1000.00 ; set maximum instantaneous speed changes (mm/min)

M203 X30000.00 Y30000.00 Z600.00 E16000.00 ; set maximum speeds (mm/min)

M201 X3000.00 Y3000.00 Z200.00 E2000.00 ; set accelerations (mm/s^2)

Perhaps F1200 is too much for the extruder? It seems fairly low speed though for retraction, so I'm not sure.

I'm kind of at a loss. Is the problem causing any actual detriments?

Heartleander81

@phaedrux

Any other Propeller use 50-70mm/s retract speed. There is my 20 very slow.

Without filament I can speed the extruder high. With optimal print Temp and filament can I extrude ~20mm/s.

I have this 20mm/s use the last 6-8 month without Problem.

Any time I have step lost on X and Y

If you look at this video you can see how the car brakes hard by braking and starting again and then continues jerking, and the belts wobble a lot. Depending on how it vibrates, the motors lose steps and I no longer print in the middle. In the long run, the jerking is not healthy for the whole mechanics

@phaedrux

But the question is why run the extruder to 0 and back to 99.4 when M83 is Configured?

When I All write to M82 and slice M82 is the same problem. At this one Point reset the firmware not the extruder.

Heartleander81

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.

Phaedrux

Have you tested in standalone mode yet without the SBC?

https://duet3d.dozuki.com/Wiki/Getting_Started_With_Duet_3#Section_Running_in_standalone_mode

Heartleander81

@phaedrux no. I dount have standalone configured

Phaedrux

As process of elimination it may help to know if the problem still presents in standalone mode.

You can copy your current config files onto a fresh SD card that has the folder structure and DWC files present and use that SD card in the Duet. That link describes in more detail.

@Phaedrux
Ok have I do.

Heartleander81

@phaedrux
The same on standalone

Heartleander81

That came after 2 weeks after I have install the toolboard 1lc V1.1

Heartleander81

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.

Phaedrux

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.

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.

dc42

@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.
