    So after most of my issues pretty much out of the way, I find my printer printing these ridges on what's supposed to be a flat surface. [​IMG]
    Is there any way to fix it? What could it be?

    That is the famous z-ribbing. There are a few solutions on the forums (search around) - first one is to tighten the coupler nuts with the L-allen wrench supplied with your robo (if you have the Beta and R1 version). If you have the new R1 +Plus, you shouldn't get ribbing at all - you will need to contact the Robo tech guys about that one.

    I don't know what's the difference between all of them. All I can tell is that it has a spool holder that attaches to the back of the printer. It has couplings with allen screws in them, it also has Z rod supports built in. Ohhhh! And a hexagon hot end

    I will try tightening the couplings first and then if that doesn't work I'll print my own couplings. Do you think that I should use ABS? PLA doesn't seem to be that easy to tap in (hard and brittle)

    Just buy a couple of these better-made couplers and swap them out. http://www.amazon.com/gp/product/B00KHTVOEU

    I have to make sure that this is the right one for me.

    It's the same one used by a couple other forum users that didn't want to do the leadscrew upgrade.

    I also recommend you order those linked by daniel871 - they will work for you. You will need to tighten those every once in a while also because they will eventually loosen up and start wobbling again. The lead screw upgrade is the solution but I understand not wanting to spend 100 bucks on it.

    Question for you Zeke: How did you run the wires of the LCD? I'm not comfortable having them just sticking out the front.

    In front where the Logo is "ROBO3D (R)TM" I literally cut the "TM" letters out in the robo's enclosure out to get the cables through. I used a little 3mm drill bit to perforate a rectangle and cut the rest with a scalpel.

    That sounds cool - any chance you can show a pic?

    Not the cleanest cut in the world but it's not visible from the top. [​IMG]

    I ordered a pair of the better shaft couplings but still printed these out. Although the hole for a rod is 0.5mm smaller due to the Z ribbing.... [​IMG]

    And they turned out to be too tight on the stepper shafts

    Can't sand those down a bit? When I did it I had to sand them down a bit with a rotary tool

    I will print new ones probably a .1 mm larger in radius. Or 0.05mm or both and see which one works to avoid taking it apart twice

    I don't have many precision tools, . I could wire your entire house with my other tools but I just started collecting precision tools.
