This is something i have overlooked before. In the instruction, at the latter end where there are photos of the connections, take a good look at the stepper connector for the x motor on the ramps board. This connection is inverted compared to y,z and extruder.
It will also help of you can upload here your Configuration.h file of the firmware you uploaded.

Ok I got it fixed.

So if you keep the cables wired as they are in the manual this will fix it:

Change the following in configuration.h

1. #define INVERT_X_DIR true to #define INVERT_X_DIR false
2. #define X_HOME_DIR -1 to #define X_HOME_DIR 1
3. With the printer off PHYSICALLY move the x-axis stopper to the left one set of pins (this makes it so it's the x max instead of x-min)

Now if you are using rep host, you need to go to printer settings > printer shape and change home X: from min to Max.

In Octoprint it looks like nothing is needed.

Now there are ways of changing pins.h so you don't have to do #3 but I prefer to do it this way.



EDIT: Ok, yes this fixed the problem. The error i was having after this was another change I set that I forgot about.

Received my package completely smashed, looks like it was run over by something. Still got my printer completely built, but when following the config guide when I try to home the x axis it doesn't want to move more than a few inches. With manual control it doesn't want to move to the right, did I get a bad board? What could the problem be? I checked all my wiring multiple times and everything is the same as the tutorial.

Some upgrades done on my printer:

Z motor stand off to reclaim around 40mm Z build height
[attachment 58434 20150719_114134.jpg]

8mm lead screw with 2mm pitch (purchased from FT) constrained on top end with a 608 bearing to eliminate the "springy" hold of the motor coupler
[attachment 58435 20150719_114151.jpg]

Replaced with a bigger X axis stepper motor
[attachment 58436 20150719_114231.jpg]


Corner brackets were also replaced. The frame is more rigid now. Currently i can set repetier's feed rate to 300 (from manual control tab) while using slicer's default printing speeds without having to worry about too much vibrations or swaying Z posts/frame. At this speed, quality gets somehow compromised but accuracy is still pretty much spot-on. As someone here as mentioned before, the provided "internal" L brackets are definitely for aesthetic purposes only and doesn't do much to rigidly attach the frames. If you have the resource, changing those brackets are recommended IMO.



A print in ABS i have done some time ago.

I got my kit also.. box looked fine.. and after inspecting all the parts.. everything seems to be there so far.. not sure about all the hardware(nuts and bolts).. but did you check your ramps board.. mine doesn't look very good ... not sure if I am going to use it if I do will have to resolder a lot of it .. and it has that burnt electronics smell.. and bent pins,,,

Judging by this thread I think we've all had that problem. If you home the X which direction does it go? For me it went to the left, if facing the front of the machine. I solved it by moving the X stop switch to the left side of the machine. I tried the Max setting and dicking around with the firmware and slicer settings and just wasted time. It would seem to sort of work for a bit then freak out again. Ultimately moving the endstop over solved it for me. My home is Y all the way back/away, and X to the left. Bottom left corner if viewed from the top.

Also, make sure your end stops are plugged into the correct spots on the RAMPS board. I don't know if the directions were messed up or I screwed up but I had the Z and X swapped and of course that made all kinds of craziness happen.

EDIT #2: If I manually move my x to the endstop and home it it seems to work until homed again. Folger tech was very quick replying and asked me for the M119 code. [imgur.com]

Just tried it, end stops are correct for z and y axis so should be correct for my x. It still doesn't home, when you hit home it just moves to the left a tiny bit and stops. After hitting home it won't go right past that position. So far I have been able to start printing by just sliding the x axis all the way to the right to the endstop and homing it, which doesn't move it. Then everything works fine.

Had the same problem. This is due to the software thinking it has hit the endstop already.

Like someone mentioned before, move the x axis endstop connection one set of pins to the left. This makes the X endstop connect to the pins meant for Xmax instead of Xmin, which is what you want.

This has fixed my problem, thank you. Does anyones x axis motor get really hot compared to the rest?

You reduced the voltage?

And it's fun to watch it get built.

How long was everyone's handling time? And how long did the USPS shipping take? According to the USPS website for me they estimate 2 days by creating a fake package.
