Hi, I have the mk4 firmware loaded, I have the oled mod installed and the 3d clippy installed all successfully. The problem that I am currently facing seems to be with the default gcode. I have the K1 speedy. Below here is the start gcode which is supposed to preload T0 filament into the hot end. ; 3DChameleon Preload Extruder 1 ; load filament 1 to extruder G0 X208 Y216 F4000 ; move to button ; three quick button presses to cancel out any active commands G0 Y218 F2000 ; press button G4 P130 ; wait for 150 ms G0 Y216 F2000 ; unpress button G4 P500 ; wait for 150 ms G0 Y218 F2000 ; press button G4 P130 ; wait for 150 ms G0 Y216 F2000 ; unpress button G4 P500 ; wait for 150 ms G0 Y218 F2000 ; press button G4 P130 ; wait for 150 ms G0 Y216 F2000 ; unpress button G4 P500 ; wait for 150 ms G0 Y218 F2000 ; press button G4 P3400 ; wait for 7 pulses G0 Y216 F2000 ; unpress button G4 P2000 ; wait for it to home The above gcode works fine it does what its supposed to. The problem happens after T0 is selected. ; select T0 G0 Y218 F2000 ; press button G4 P550 ; wait for 550 milliseconds (why does it need to wait 550 milliseconds? When this button press is happening on the OLED displays each prompt and I can hear the pulse of the motor but nothing else happens) G0 Y216 F2000 ; unpress button G4 P2000 ; all done Heres where the issue happens, the button gets pressed for the 18500 but no filament is loading or unloading, the OLED shows the prompts and i can hear the motor pulsing. Once the button is let go the chameleon the servo activates and the chameleon changes the selected slot) ; load T0 G4 P500 G0 Y218 F2000 ; press button G4 P18500 ; load G0 E25 F2070 ; <<<--- adjust this E value to tune extruder loading G0 E20 F250 G0 X220 Y210 Z.2 F1000; move to extruders assigned purge line G92 E0 G0 Y0 E100; purge the extruder. G4 P2000 ; all done At this point the printer just carrys on and no filament is loaded. But if i press and hold the button manually filament starts to load. So what did I mess up here and how would I fix it?

Printer: K1 speedy The issue: After configuring the gcode to move to the button and entering the correct values x/y it does not appear to work properly. What happens: The printer does the normal start gcode, auto bed level, heats up etc. When it goes to touch the button, it does 3 quick button presses, lets off for a moment, then presses and holds for a really long time. I can hear the cameleon ticking, but no filament is loaded or unloaded. Then the print head moves off as if it starts the print. I made sure that the cameleon is on mode 3, its homed properly before the print starts. If I manually press the switch I can successfully load/unload filament in the right directions. What am I doing wrong? Heres my start gcode: SET_FILAMENT_SENSOR SENSOR=filament_sensor ENABLE=0 SET_FILAMENT_SENSOR SENSOR=filament_sensor_2 ENABLE=0 M82 ;absolute extrusion mode START_PRINT EXTRUDER_TEMP=[first_layer_temperature] BED_TEMP=[first_layer_bed_temperature] G92 E0 ; 3DChameleon Preload Extruder 1 ; load filament 1 to extruder G0 X206 Y216 F10000 ; move to button ; three quick button presses to cancel out any active commands G0 Y219 F2000 ; press button G4 P150 ; wait for 150 ms G0 Y215 F2000 ; unpress button G4 P150 ; wait for 150 ms G0 Y219 F2000 ; press button G4 P150 ; wait for 150 ms G0 Y215 F2000 ; unpress button G4 P150 ; wait for 150 ms G0 Y219 F2000 ; press button G4 P150 ; wait for 150 ms G0 Y215 F2000 ; unpress button G4 P150 ; wait for 150 ms G0 Y219 F2000 ; press button G4 P3200 ; wait for 7 pulses G0 Y215 F2000 ; unpress button G4 P2000 ; wait for it to home ; select T0 G0 Y219 F2000 ; press button G4 P550 ; wait for 550 milliseconds G0 Y215 F2000 ; unpress button G4 P2000 ; all done ; load T0 for 28 seconds and into extruder G0 Y219 F2000 ; press button G4 P20000 ; wait for 27 seconds G0 E50 F500 ; <<<--- adjust this E value to tune extruder loading G0 X220 Y210 Z.2 F1000; move to extruders assigned purge line G0 Y0 E60; purge the extruder.

I am having trouble finding out how to get the exact extruder to hot end mm calculation, since the k1, I cannot advance the extruder in menu or in a slicer. How would I determine this value?

Hi, I havent done anything to this thing yet. I hooked it all up and mounted to my K1 (speedy). The trouble that i am having is i cannot by hand push the filament through the stepper feeder expect for 1 will go through with a bit of force. I took it apart and I can feed the to the gears but because theres no real tension its not straightening out the filament to get ot the other side. When I visually inspect the feeder I can see the holes arent quite lined up from 1 side to the other.
