SoliForum - 3D Printing Community → XYZ Printing DaVinci → Repetier Filament Loading Too Short
Finally, the DAV 1.0, "Screamin' Meanie", Bowden Extruder is up and running.
When loading the filament I have keep pressing the Load button on the LCD until it reaches the hot end.
I would like to start the filament from the reel thru the extruder,
then hit load to extrude thru the bowden tube to the hot end.
How can this be accomplished ?

You would need to use Repetier host and tell it to feed the amount of filament required for the distance you need.. Most don't use built in load functions. We simply heat the hot end to the required temp then push the filament through by hand by releasing the tension mech on the extruder..
You can edit the value in the configuration_h file (line# is 1743 in the github file or search for #define UI_SET_PRESET_UNLOAD_LOAD_DISTANCE 60) and change the value in this case 60 to whatever value you want and this will now work with the load/unload menu choices on the LCD screen. I believe the value is the distance in mm you want to feed. Once you change it, you would need to upload and save the new firmware.

Ok, but the loading/unloading will be at set value distance all the time.
Maybe a Gcode script ? To use only for loading a new filament.
I notice RepHost has a Send Script function. Manual control buttons.
Ill try to look for a extruder gcode.
Hot end on-extrude 350-hot end off ??
I'm confused. I thought you were asking how to change the load/unload value to match the bowden setup. Why wouldn't you want it to permanently be set to the new value? If you are just wanting to extrude/retract smaller amounts for times other than loading/unloading filament, there is a gcode for that "G1 EXX (or -XX) F(speed of extrusion).

Only to run it thru for a filament change.
I want to bring the filament up the gears, hit a button to extrude down the hot end.
Its a PITA to push it thru.
Ok, G1. That worked. thanks
Is there a gcode to turn on the hot end also, other than turning on hot end separately thru manual control ?
Edit: Think I found it.
M109 S230; wait for extruder temp to be reached
G1 E200 F20
M104 S0 ; kill extruder temperature
Hers the DAV bowden setup.
No. Didnt work. Went hot then off w/out extruding.
Now Im guessing.
I'm not sure why this didn't work. I'll check my code when I get home this evening to see what is different. I do think that F20 is really slow. I think I use F500. If I remember correctly, the F value is mm/minute.
Using G-code or M-code works, combined doesnt. I dont get it.
For now, Ill need to use the Repetier manual control buttons. Extruder options are only 10,50,100.
Hotend button on. But you have to remember to shut it off. I accidentally left the the hot end on. Thats a Safety issue.
Repetier says the UI for the buttons cant be changed.
M109 S230; wait for extruder temp to be reached
G1 E200 F100
M300 S400 P5000; Play beep sound
M0; shut down
I tried using M104 S230. Didnt work w/ g-code.
Start hot end- 230C
Hold temp
Extrude (length of bowden tube) at say 100mm/sec
Purge 25mm at 20mm/sec
Shut off hot end
Play sound
M104 sets the extruder temp but I believe immediately goes on to process the next command, in this case extrude filament. Since the extruder was still cold, I suspect it tried to extrude but just grinded instead. M109 sets the extruder temperature, but waits until it is reached before processing the next command. I'm not sure why the original code didn't work though.
