Hi Ian

I did notice that in the change logs.

I also tried to include the results of m122 but they were flagged as spam. how do you upload them?

Art

@phaedrux The problem seems to be between v2.01 and v2.02.
2.01 perfect as it was before but with v2.02 x and y motors are stuttering on radial moves.
Both with the same config file.

I have also removed the filament sensor so it is not that

Art

@flyingscot
I have gone back to firmware v2.01 and the printer is working perfectly again so it is either the firmware upgrade that is causing the stuttering radial moves or the addition of the laser filament sensor.

Has anyone any idea what may be causing this?

Art

My printer has been working perfectly for years untiI I upgraded to 2.05.1 to use a laser filament sensor.
Since the upgrade the printer is stuttering around radius moves.
Has anyone else had this kind of problem? I did copy the sd card before upgrading can I revert back to old firmware?

Arthur

@flyingscot Its now running well on v2.05. It must have been the microstepping with interpolation that fixed it.

I did go back to 2.02 and the problem returned. Back to 2.05 and all is well.

Thanks for your help

Art

@dc42 The circle is generated by G1 moves and there is no M205 in the GCode.

Art

@dc42 I will look into not sure where to look. The test file is a cylinder drawn in solidworks saved as an stl and sliced with cura. it prints well with V2.01 but not in V2.02.

M566 in config is: M566 X600 Y600 Z120 E2000

Art

@phaedrux Morning

Unfortunately it is still the same.
its strange printing a circle anticlockwise the speed is not constant it slows down between 2 o'clock and 10 o'clock and again between 8 o'clock and 4 o'clock,
Back to 2.01 and its fine.
Printer is a core x,y

Change to config was:
M350 X16 Y16 Z16 E16 I1 ; Configure microstepping
M92 X100 Y100 Z400 E408 ; Set steps per mm
