    I didn't like the new version personally. Didn't seem "finished" to me.
    I'd be interested to hear if anyone is using it and is happy with it.

    15.x Is the older more stable version while 2.x is the newer one. Too much of the new one is still work in progres

    Still looking pretty good, but I'm having a hard time completing this model.

    When the Robo is doing those little overhangs at the top they warp a little until it gets it flattened out. The hotend is hitting them when it's passing over them and knocking the model loose. The grey one. I caught as it did it and I held my finger on the raft until it adhered again. You can see the the flaw near the top.

    Increase Z hop?

    Other than that I think the model looks pretty good.

    @Curtis Wolfe I find printing with a BRIM better than printing with a RAFT on models with small contact areas, the raft is easier to cut away from the model and since the model is actually on the bed the bottom layer looks much better.

    What do you think about my hotend striking the model? increase Z-hop?

    That might work, I pretty much use 0.8 mm for every profile. Be careful setting this on the R1+PLUS it has to be in multiples of 0.02 mm or it won't work as expected.

    Thanks. good to know. It was set at .075. Maybe increase it to .155. That's increased in multiples of .02.

    .8mm seems like a lot

    Are you on the R1 +PLUS ?

    That must be the new math 0.155 is not evenly divisible by 0.02 at least not when I went to school back in the prehistoric era. Why not just try 0.2 (see how this works 0.02 x 10 = 0.2) I actually have finer resolution than a R1+Plus I am using TR8*2 lead screws and the PLUS uses TR8*4 so I can move Z in increments of 0.01 and the PLUS can only do 0.02 mm

    LOL! No. I just increased the setting it is at (.075) by .02 x 5, but now I understand what you mean. Thanks

    Im using Cura 15.04.6

    Slowing way down on those overhangs may help. I get the same issue on balls and small ball joints and such. Slowing down has helped but I'm still learning.

    If I want to hook up the printer via USB to Matter Control to look some things do I have to disconnect the LCD?

    I pulled off the bed to check screws for tightness.

    Man, Those Y tensioners were way loose.

    I use my PC/USB at the same time as the LCD Controller is connected. I can print from either or at will.

    I've been running some G29 test. To my eyes one of the Z switches on the other side of where its probing is not disengaging.

    Am I way off here?

    Normal. The two switches are probably not perfectly aligned and if they were, one side is heavier than the other.
    Feel free to experiment with fine-tuning the position of the switch on the brass but :)

    Why is Cura messing with me now. I went to put a brim instead of a raft after adjusting my Z hop and it wouldn't do it. It kept putting the raft on. I switched models and even though I told it to put a brim or raft on it wouldn't do either. It also changed the start up even though the G-code wasn't changed. I couldn't get anything to stick so suspecting I had a bed level issue I went through the G29 tests and try manually leveling with the Z axis screws. The image above is where I ended up. Went back to Matter Control to slice the model and no problem. The brim went down and it printed the model. Not a great print but at least the hotend wasn't striking it. Which is the one thing I wanted fixed. The Z-hop is set at .5mm in MC so I'm not surprised it fixed that problem.

    Re-install Cura?

    I can't make any progress because I'm always at a different starting point each day it seems.
