thingiverse

These files were created to mimic the M600 command from Marlin on the Duet Wifi board. They are specifically designed for use on the RailCore2 300ZL, but if you're using them with another machine, you may need to adjust things. To use these files while printing, either press the "Pause" button or insert M25 commands into your gcode files. You'll need two normally open momentary switches to build this setup. Unzip "Load_ResumeButtonsFiles_SysFolder" into your sys directory (This will overwrite your existing pause.g, resume.g and trigger2-trigger7 files if they already exist) Unzip "Load_ResumeButtonsFiles_MacrosFolder" into the macros directory Add this to your config.g Assigning Switches to E0=RESU and E1=LOAD M581 T2 E0 S0 ;Runs trigger2.g file when pressed - Resets Load Macros M581 T6 E0 S0 C1; Runs trigger6.g file when pressed during print - Resumes print after resetting load macros M581 T3 E1 S0 C1 ;Runs trigger3.g file when pressed during print - Runs before Trigger 7 to get temp back up during print M581 T7 E1 S0 ;Runs trigger7.g file when pressed - First step of Unload process The "LOAD" switch is connected to E1 1st Press - Unloads filament (When printing it waits for Hot end temperature to stabilize, When not printing you must intialize hot end temperature before pressing) 2nd Press - Loads filament and extrudes 50mm 3rd Press - All additional presses purge 50mm of filament The "RESU" switch is connected to E0 When printing this button will Resume the print and reset the LOAD button back to initial state When not printing this button will reset the LOAD button back to it's initial state
