FolgerTech 2020 Prusa i3 - New Build

[tjnamtiw]

These are suggestions I sent to Folger Tech to update their instruction manual so you will have the X axis move properly and not be inverted. It should get you going.

"Unlike all the other repraps, FT put the X homing switch on the right side, which is XMAX and not XMIN. The first thing that must be changed is to plug the X end stop into the Ramps board NEXT to the Y end stop plug and NOT skip a space. The pins to the right of the Y end stop pins is for XMAX. The one you show in your manual is for XMIN. That is at STEP 23, picture 10. “Again you are going to skip a row” is incorrect. It needs to go to the immediate right of the Y end stop plug.

Then in configuration.h in Arduino make sure that
#define INVERT_X_DIR true is CHANGED to #define INVERT_X_DIR false
AND
#define X_HOME_DIR -1 is CHANGED to #define X_HOME_DIR 1

Keep the plug for the X axis servo motor wires reversed as shown in the picture. Without an explanation, many people think that you made a mistake in the picture. Make note of the fact that the orientation of the colored wires is correct.

Finally, in Repetier, tell the user to go to printer settings/printer shape and change ‘home X’ from MIN to MAX.''

Yes, physically reversing the wiring to the X stepper would do it as well. There were enough little inconsistencies in the pictures (or at least comparing the pictures to the text) that I decided to connect the plugs all in the same direction.

Overall I am happy with the product. It is a good value for the $$.

It takes more than just reversing the wiring. Read ALL the steps I wrote. An important one is the fact that you have to plug the X end stop into a different position than is shown on the instructions. Also in Repetier, you have to select differently. It takes 5 minutes but you have to do ALL of those things.

Thanks very much, tjnamtiw! Your suggestions helped me get the FT 2020 Prusa working correctly.

Thanks very much, tjnamtiw! Your suggestions helped me get the FT 2020 Prusa working correctly.

I'm glad it helped you. I am amazed that FT doesn't update their build file knowing that the machine won't work with their directions.

Hi tjnamtiw, I have the same issue, however after following your directions I'm still having issues. It seems to want to home to the left side and not my bed is not centered?

Any suggestions?

Thanks!
