G2S Extruder Feeds in Reverse

Post by ECruz »

I have everything working except the extruders feed in the reverse direction. Can this be fixed in the firmware?

You can fix it here in configuraion.h:

#define INVERT_X_DIR false // for Mendel set to false, for Orca set to true
#define INVERT_Y_DIR false // for Mendel set to true, for Orca set to false
#define INVERT_Z_DIR false // for Mendel set to false, for Orca set to true
#define INVERT_E0_DIR true // for direct drive extruder v9 set to true, for geared extruder set to false
#define INVERT_E1_DIR false // for direct drive extruder v9 set to true, for geared extruder set to false
#define INVERT_E2_DIR false // for direct drive extruder v9 set to true, for geared extruder set to false

I changed the firmware to what you suggested. This changed the X, Y, and Z axis which made the extruder hot ends slam into the plate. Now filament will not go thru when I manually feed the filament. Are the extruder hot ends under warranty?

What I was looking for is to reverse the filament feed not the direction of the axis.

:shock: I mean you can refer to this to change the settings, not all of them! You just need to change the corresponding one for your estruders.

I have fixed the reverse filament feeding and cleaned the blocked hotend.

I can feed the filament manually thru Repetier but when I try to print something, nothing prints and the filament gets jammed.

Could this be a problem with my Slicer settings?

What's material you use? How about the temperrature? And you can adjust the screw on the extruder motor to see if it works.

The material is PLA. I have tried different temperatures starting from 190 to 210.

I have adjusted the screw on the extruder motor many times. If it's too loose, the filament doesn't move, too tight and it won't move. It is somewhere in the middle. Should the tension be loose or tight to prevent too much feeding?

If you can manually extrude the filament through the repetier, so how about using a different brand of filament? sometimes the defective filament will cause the problem.

I bought one of the top brands listed on most 3D printing websites and got the same result.

" when I try to print something, nothing prints and the filament gets jammed"
When did this happen? Is it the first layer? If so, then the nozzle is too close to the bed and will cause the problem.
And another way is try to slow down the feedrate from 100 to 50, see what the reasult is. Once I print something very small and the nozzle needs to run back and forth in a very short distance at a very fast speed, the nozzle jammed every time in the same palce. I change the feedrate and it worked out.
