Marlin Issue

[Tattered]

Hi. I have a Prusa I3 Pro B and am having an annoying issue with marlin I hope someone can help me with.

Everything seems to work through marlin and it seems to be uploading onto the printer, but, I can't change the steps for the extruder, it just doesn't seem to recognise it. Meaning I have to change it manually through the LCD every time I turn the printer on. I have re-loaded marlin to the original but the steps still won't change on the printer. (I have changed them in the past and it worked fine)

This is my code. nothing special:

#define DEFAULT_AXIS_STEPS_PER_UNIT {80,80,2560,525} // MXL, Z M8=1.25, (geard nema)
#define DEFAULT_MAX_FEEDRATE {400, 400, 2, 45} // (mm/sec)
#define DEFAULT_MAX_ACCELERATION {5000,5000,50,5000}

But it just seems to be stuck at 100 on the printer.

Any ideas?

Have you clicked "store memory" after you change it?

Beautiful, thank you. I hadn't done that previously. Didn't work the first time, but, pressed 'restore', 'load' then 'store' again and its working again now.

your a champion.
