    Hey everyone.

    I have had a robo r1 plus not (+plus) since early June. I'm looking into the lead screw upgrade but I thought it might be a good idea to start a thread of before and after prints with the lead screw upgrades. I'm hoping you guys will post before and afters to show off your results.

    Already been done by at least one other person (also in the leadscrew upgrade thread).
    @jbigler1986 had a thread on this I believe.

    Yea but I thought maybe we could have a straightforward thread with nothing but pictures.

    No mystery :)
    If you had ribbing before, you won't after.

    Not everyone had ribbing (although it was common) and not to the same extent for those who did.

    You just have a Robo3D R1, not a plus.

    If you have print issues, the lead screws will fix it. If you don't have issues it won't do anything

    I got some new couplers and it made a decent difference but The is still ribbing. It is mostly noticeable on straight edges like a cylinder or rectangular prism. That before after looks good on the ears and trunk. The edges look a lot smoother.

    Well, you do realize there is more than the couplers involved in this. Some of it is in the replacement leadscrews (new threading) as well (new steppers too).

    I didn't do a great job with those picture because of lighting - the difference is even more dramatic when you hold it in your hands. I also did the coupler update at first and that helped a bit but nothing has worked as good as this lead screw upgrade. The threads being thicker means less movement on the z-axis that also leads to better prints and a lot quieter printing.

    I did the coupler update with no difference. Others have had pretty good success though. Then when I removed my leadscrews for the new ones, I realized that the hex nut that rides on the screws was drilled off center on both the old leadscrews. That would give some fits as well. Something to check if you want to keep trying for a cheap solution to your ribbing. Although, the new threads and setup of the upgraded leadscrews are worth every penny to me. Like others have said, it's more than just removing couplers. It is a whole new setup that is solid. I have thought about getting new hex nuts and just trying to see if that would have fixed it for me, but it's onwards and upwards. No looking back.

    Wow yours is a huge improvement. What was your layer height?

    200 microns. All standard settings. I was living with it until I printed a part that required precision and the ribbing kept for the part fitting correctly. It was at that point I had to break down and get the upgrade. Way too much post processing to make it worth even printing precision parts. Now things are tight and right. Couldn't be happier.

    I can't find a before picture but it was worse than @danzca6 was. Here is a picture of the first print after. [​IMG]

    see, and you have a little squish flare on the first layer also. I started getting that as well. I think I just need to adjust my z offset and possible calibrate the extruder. Not a big deal at all, but glad to see I wasn't the only one.
