change filament go crazy after update to 1.4.8

Hello,

I updated my raspberry pi from 1.4.4 to 1.4.8 by using the update function.

After the update the option to change filament seemed to go crazy.

I set the loading with 300mm Fast Distance and 50mm slow Distance, with 1.4.4 it worked perfectly,

now it loads about double ... I solved it for the moment by setting 180mm and 30mm

just to not break the printer but actually it loads

about 300mm Fast and 50mm Slow with the values set to 180mm and 30mm

When I test this with your values I get this commands send in console:

As you see it totals to 350mm which is correct.

What do you get as output if you do? If you have a custom insert script it may add extra gcode not considered by our moves. Actually changed gcode to prevent wrong extrusions as you see by setting mode and E position we thing should have before sending the move now.

Change Filament (using 7'' touchscreen interface)

Ok found the reason. The initalzing G92 does not get updated between moves here making each successive move add 50 more mm due to being in absolute E mode. Will fix it for 1.4.9 coming probably next week.

Thanks for the help.
