What do you have in bed.g?

Have you tried with mesh compensation disabled?

If I edit the G-code that it does everything at z-height, say 5mm, then it's the same with the X-axis. runs on stops - extruder is doing something - X axis continues to run. As mentioned, if I delete or comment out the first Retract G1 E-0.6000 F1200 from the sliced file, there are no problems with the X axis or the extruder

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.

Heartleander81

@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?

Heartleander81

@phaedrux
Have I do yesterday. But with M82.

I can try it in 30 min.

Heartleander81

@phaedrux

Is the same

Phaedrux

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.

Is that video better?

Phaedrux

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?

Heartleander81

@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.

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
