Any suggestions what I should do to test what is causing this please? Any ideeas what I can look for in the GCODE to check if something is changing it?
Be aware that Marlin uses "sticky" parameters. All settings stay at the last value until the next reboot (or M501).
If you want to be sure that every print starts with the stored values, add M501 at the beginning of the start script.
If you want to check the generated gcode: jerk can be changed with M205, acceleration with M204.
Yeah, when I updated the FW I saved it. Something had changed the max_x_jerk etc. from 12 to 20 (just double checked). Reboot and it was back to normal.

Thanks - good info.
Definitely happening in Cura. I even have M204 + M205 setup in my startup code for the correct values... but then after that, I get this:

Did you save it in EEPROM? After alter the value you should digit M500 to save it
I hope it helps

Definitely happening in Cura. I even have M204 + M205 setup in my startup code for the correct values... but then after that, I get this:
;LAYER_COUNT:50
;LAYER:0
M107
M204 S5000
M205 X30 Y30
G0 F3600 X130.766 Y130.38 Z0.2
M204 S500
M205 X20 Y20
;TYPE:SKIRT
Above we can see X20 Y20 - which is what it ends up.
Just to double check... I don't have "Enable Acceleration Control" or "Enable Jerk Control" on, that's all I need to switch off right?
Let me reset my profile again and see if I still get that. At least I can find out without having to print now. Thanks
