    I have gotten the Marlin 2.0.x Bugfix setup and working on my test machine. It has been leveled and printing as we speak. There is a new dual Z alignment feature that I enabled but I don't believe it's setup right yet so it doesn't do anything if you try it. I'll be working on that and will update if I can get that feature working correctly.

    Most other features appear to be working the way they are supposed to.

    The firmware is setup for the stock R1+ with the standard reprapdiscount lcd enabled. You will have to change the firmware if you have a different LCD. I also widened the temperature check on the thermistor and bed because I was getting a few temp fall false positive errors.

    If you have any questions feel free to ask. I am not a Marlin programmer, I just edited the parameters for our printers.

    I'm still not able to upload files on this forum for some reason so if someone else can upload it for easier download, I would appreciate it. Thanks!

    Too big of a file to upload as kitted and I hate to trim a lot out just to get it to fit.

    Does this work?

    There are compilation warnings, PID values are defined twice in Configuration.h, commenting out the Ultimaker settings will get rid of them.

    Funny, I re-ran the verify and it didn't give me an error but it's definitely there lol

    Your file won't open for me for some reason, says it's corrupted or damaged.

    I'll fix my first post with the correct PID temp.

    Try 7-zip or WinRAR. I just downloaded and extracted the file above.

    7-Zip is free, https://www.7-zip.org/

    I was using 7-Zip. But my version was from 2014...lol

    Just re-downloaded to current version since it doesn't have an update feature and it works fine now.

    Before I go attempt this, is it possible to make this work with the R1 non-plus?

    Different Z steps is all. The R1 beta, the R1 and the R1+ all have different Z steps/mm

    So I don't have to worry about the R1 having both Z steppers on one driver where R1+ uses the E1 stepper?

    The reason I ask is that I have difficulty homing and get motor buzz on one or both Z steppers.

    The R1 and beta used a single stepper driver for both Z motors and the R1+ used two. The RAMPS 1.4 card is DESIGNED to use only one Z stepper driver and this is fine because the acceleration and movement speeds of the Z are tiny.

    It should not matter on Z steps because the PINS.H for the ones with the dual stepper drivers will still map to a single Z steps/mm

    It matter electrically because if one of the stepper motors or stepper drivers is out of whack then your Z will be in trouble.

    there just is no good reason to use two z stepper drivers on a RAMPS board. It really buys you no advantage in the design used by most RepRap style printers (including the Robo)

    Thank You.

    It seems that there is nothing wrong with the steppers, nor driver.

    I can home and print with 1.1.7 (1.1.1 Mesh)

    I cannot home with 2.0.x_Bugfix. The Z motors buzz and sometimes only one turns.

    I did change the steps and other lines in Configuration.h

    I have the motors working again. I had to comment out two lines in Configuration_adv.h
    #define Z_STEPPER_AUTO_ALIGN
    #define Z_DUAL_STEPPER_DRIVERS

    That would make sense. Those are the comments I added to get the dual z working on the R1+. The stepper align is experimental and doesn't seem to be working yet, but it is in the menu.

    Does this bring anything new worth using over something like 1.1.7? I'm going to be starting things over so thought it might be worth going with the newest.

    Yes. To change to a V6 you need to adjust your thermistor type in the firmware (and your max temp depending on what its set at-if you want to- cant recall for the R1+, been to long since I was stock)
