V1.3.1 hephestos

[jpralves]

It seems that the function lcd_sdcard_stop() - Called by the LCD "Stop Print" function - in file ultralcd.cpp is driving the X or Y axis to the far end due to this code:

+ #if X_MAX_POS < 250
+ plan_buffer_line(X_MIN_POS, 150, current_position[Z_AXIS]+20, current_position[E_AXIS], manual_feedrate[X_AXIS]/60, active_extruder);
+ #else
+ plan_buffer_line(X_MAX_POS-15, Y_MAX_POS-15, Z_MAX_POS-15, current_position[E_AXIS], manual_feedrate[X_AXIS]/60, active_extruder);
+ #endif

Its dangerous and in the case of the Hephestos should be removed. I've seen this behaviour several times in my Printer.

It is a nice fix.

Could you please submit just the fix to main branch??

Cheers.

In Marlin/ultralcd.cpp:

 quickStop();

• #if X_MAX_POS < 250

It seems that the function lcd_sdcard_stop() - Called by the LCD "Stop
Print" function - in file ultralcd.cpp is driving the X or Y axis to the
far end of Prusa i3 Hephestos - due to this code:

• #if X_MAX_POS < 250
• plan_buffer_line(X_MIN_POS, 150, current_position[Z_AXIS]+20, current_position[E_AXIS], manual_feedrate[X_AXIS]/60, active_extruder);
• #else
• plan_buffer_line(X_MAX_POS-15, Y_MAX_POS-15, Z_MAX_POS-15, current_position[E_AXIS], manual_feedrate[X_AXIS]/60, active_extruder);
• #endif

The commits in your pull request don't seem related to your comment -- I
think they are based on a different branch than the ErikZalm/Marlin one.

Also, the X-movement code you are concerned about does not seem to be
part of ErikZalm/Marlin. I think it was probably added specifically for
the witbox or hephestos project.. I agree, though, that it looks like a
bad idea. If anything, 'stop print' should probably just move "up" a bit
(positive Z).

Yup. I've seen my mistake I'll provide a nicer patch to the proper branch.
