Issues after prime

Ok I hope that is all what you need

What do you have in bed.g?
Have you tried with mesh compensation disabled?

This still very much sounds like it's in absolute extrusion mode and it's pausing while it's trying to move the extruder to undo all of the previous extrusion commands.

I apologize if my sentences read clumsily or unkindly. I work with google translators because my english is very bad. I am very, very grateful for the help that I am getting because I am slowly becoming desperate.

@phaedrux
ok i understand that and is understandable. but why is he doing this? in the start code it runs great in the M83 and after that I no longer give an M82 command. I switched Simplify3D to M83 and the sliced code also looks like it. -

Can you try commenting out the accelerometer command?
-
@phaedrux
Have I do yesterday. But with M82.I can try it in 30 min.
-
Is the same
-
your video is very short and a little confusing to me. It looks like it goes into slow motion? Is that to show the stuttering? Can you upload a new video that's a bit longer and doesn't go to slow mo? Describe for us exactly at what point each piece of gcode is executing from the time you hit print to the time you see the problem.
-
This Video is without slow motion and with Sound.

@phaedrux
Is that video better? -
Yes I think so. At what point in the gcode stream does the video start?
It looks like it's just finished homing, or is that it finishing G32?, moves to the corner, purges some filament, then draws a purge line, and moves to start another line across the bed.
What is in M98 P"startGcode" ?
Is it this?

What do you have in homez.g?

Yes that is my startcodeThe 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.

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

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?
-
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
-
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.
-
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.
