Hi,

I am testing the acceleration and I have found a problem.
When I rotate the part by 180°, the printing is almost good.
I will try to explain, when the head travels away from the motor, I have minimal ghosting, but when the head comes towards the motor, the ghosting appears.
I have the same situation with X and Y axes.

I checked the motor, the belt, ... all seem correct but I am sure I have a problem.

Did you have the same problem ?
Regards.

The picture represents the same part printed twice with a 180° rotation to show how the aberration appears in only one direction.

Hi,

Yes I uncommented the line.
I did tests, but at the same time I have found another problem and I have to resolve it before.
I will post this problem in the right category.

Regards.

You could find the config.g

config.g

it has been generated by the RepRapFirmware Configuration Tool.

I just comment the lines M201, M203, M205 to do test.
I used Cura to generate the gcode.

Thanks.

No problem

AA8_acceleration_test_piece_modify.gcode

Sorry, I made a mistake in my previous post.
I have this in my gcode.

;Layer:0
M400
M201 X3000 Y3000
M204 P400

;Layer:5
M204 P800

;Layer:10
M204 P1200

......

;Layer:25
M204 P2400.

regards.

Hello,

I tried to do an acceleration test, but the result doesn't change.
First test I printed with no gcode modification of the part.
Second test.
In the gcode, I added the M201 P400 before layer=0 and every five centimeters, I updated the code with M201 P800, M201 P1200, ....
Between test one and test two, the parts are identical like the code M201 doesn't work.

I read in the old post, that I need to add the M400 before each M201, I tried but same result.

I have downloaded the part from the web interface.

I'm a beginner, I think we have a PEBCAK issue
Thanks for helping me.

Regards.
