DWC Load Unload / OK New Info Please help as this is strange.
-
I have this problem that after connecting to DWC and doing homing if I use Load Filament it spits the filament out while Unload Filament will load it.
Is this a bug our is there something wrong in my config, everthing else seems to be working and also the prints do not have problems on the direction
the extruder should move.Thanks
-
Does anyone know?
-
I just used "unload filament" yesterday, and it worked correctly for me.
-
Well I know it should but mine does not so I wonder if it could be something in the setup of my config.
-
OK reading the new wiki page I found something there about the macros I try changing that to see if it works.
-
OK I did some testing and I found out that if I use Unload or Load befor homing they work correctly.
Example unload is
; Unload filament
G1 E-5 F500
G1 E-500 F3600Now after even homing only the X axis they are inverted.
My Home X is:
; homex.g
; called to home the X axis

G91 ; relative positioning
G1 Z5 F6000 ; lift Z relative to current position
G1 S1 X410 F1800 ; move quickly to X axis endstop and stop there (first pass)
G1 X-5 F6000 ; go back a few mm
G1 S1 X410 F360 ; move slowly to X axis endstop once more (second pass)
G1 Z-5 F6000 ; lower Z again
G90 ; absolute positioningI do not see any thing with G31 EXXX so what is causing this problem?
This happens after I home that is why it never worked. -
Please post your complete config.g file.

I looked but cann't find anything regarding Extruder other than the motor or speed.
It prints perfectly or almost.

As you have commented out the M83 command in config.g, you will need to add M83 commands at the start of your filament load and unload macros.
-
Ah I had read that it gave some problems and that is why I commented it.
If I use it only the macros it will not be enabled like if I used it in the config?
Do you think it is better or not to use it?Thanks
-
Having M83 in config.g only causes problems if you slice your models using absolute extruder coordinates (instead of the relative coordinates we recommend) AND you don't include a M82 command in the start gcode to tell the firmware that.
In macro files, extruder coordinates are always relative to the present position, because there is no way for the macro to know how much extrusion has already been done.
Absolute extruder coordinates are a hangover from the early days of 3D printing. Now that we have extrusion factor modification (M221), mixing extruders and macro files, they make no sense.
