    I recently dusted off my R1+, reflashed the firmware, and am not sure what it happening. When I AutoHome the printer, the X and Y axis home fine, however the Z axis does not. It does not move down and makes a whine while attempting to move down. After a few seconds, the X carriage crashes into the other side. I also have an issue where I can move any axis in increments, but with the 4th or 5th increment, it stalls and then continues to move in whichever direction it was incrementing in. I've reflashed the firmware multiple times and no avail. One of the times it attempted to home, it crashed into the heated bed, which popped the limit switches off the hex on the Z axis. I re-tightened the switches onto the bed and ensured they were calibrated correctly. I'm not sure what else to do.

    Exactly which firmware did you use (provide a link to it) since you may well have loaded the incorrect one.
    The R1 beta, R1 and R1+ are all VERY similarly labeled and look the same, but have quite different firmware.

    Also be sure you know exactly which model you have (beta, R1, R1+) a picture of the bed and the spot where the Z rods go through the bottom of the case to the steppers would let us identify which one you have.

    So which ZIP file on that page did you use -- there are several :) Most not what you want.

    Also, are you certain you have the R1+ and not say, the R1? If you are then make sure you used the correct one: ROBO3DR1PLUSV2.zip

    The behavior sounds like you have used the incorrect one...

    The standard R1+ zip.

    well, just be certain that you actually are using it on an R1+ then and you should be fine.
    If you use it on an R1 or beta -- no, not fine :)

    Yep R1+. I followed the steps to flash the firmware, but still no luck.

    Well, if you are certain you have the correct firmware loaded then I'd start suspecting the electronics.

    There are two approaches to this.
    1) You can start swapping out the bits board-by-board until you find the bad one(s).
    2) Get the less than $50 all-in-one kit from Amazon and just swap everything. Then sort out the bad part if you want to ...

    I usually say:

    1) swap the RAMPS (the R1+ has a slightly customized one so you need to do some minor rewiring as that "custom" one is no longer around. See this thread: http://community.robo3d.com/index.p...and-rewiring-to-make-generic-ramps-work.8356/

    [You may or may not want to swap the existing stepper drivers out for your old ones, I'd say just use the new ones until you sort out what is bad]

    2) Swap the Arduino (and reload the firmware)

    Here are some examples of the all-in-one-kits:

    https://smile.amazon.com/Aokin-Printer-Controller-Arduino-Heatsink/dp/B07Q5R6YSK
    https://smile.amazon.com/Printer-RAMPS-Controller-MEGA2560-Jumper/dp/B079294B93
    https://smile.amazon.com/Printer-RAMPS-Controller-MEGA2560-Jumper/dp/B079294B93
    https://smile.amazon.com/OSOYOO-Printer-Controller-Stepper-Heatsink/dp/B0111ZSS2O

    Check them out and there are a LOT more so you have options. I'd suggest using a Prime seller since there will be no warranty hassles. If you do not swap the Arduino then reloading the firmware is not required.

    The whine with no movement is usually a bad stepper driver or a failed stepper. You won't know until you swap something. If it drops steps while stepping an axis it can well lose track of where it is and then it will crash out when it tries to go past MAX.

    given the price NONE of the boards are cost-effective to repair, but you can always do that if you just want to experiment :)

    Thanks! I'll look at those

    I did get a print log from MatterControl. I am not sure if this helps diagnose anything.

    Just remember for troubleshooting that the printer/firmware "knows" exactly ONE position for each Axis -- home. Everything else is math so if something gets in the way of the steps it will get "lost"

    Video on how it dies not like to move down even with all stops open:


    Video of the noises it makes when it takes over itself:

    That make sense because for it to want to move down the Z endstops (both of them) must be CLOSED -- they are inverted :)

    Rememeber, for an endstop,
    inverted -> OPEN = home
    non-inverted -> CLOSED = home

    X and Y are NOT inverted. If it thinks it is HOME on any axis it will not want to move further HOME in that axis. It will STOP.

    See, it even refuses to move down when they are CLOSED. It makes that noise similar to the 2nd video.

    Then you have bad electronics -- not bad endstops.

    and I'd bet on the RAMPS board being the culprit.
    You need to get a new one (and refer to that thread on how to do the rewire for the generic RAMPS)

    However, it is better to get all of the electronics since they are rather inexpensive

    That's what I'm thinking. Would you say replace all the boards first, and then if that doesn't work, replace the motors second?

    While normally I'd say follow the procedure I outlined above and swap the RAMPS, then the drivers, then the Arduino and then worry about steppers....

    It is easier to just swap all of the stack of electronics in one pass (RAMPS and Arduino and stepper drivers) since they are all connected to each other in a nice stack.

    Bear in mind that you will need to re-land some of the wiring as covered in that other thread because of the minor differences in the RoboRamps versus the standard RAMPS 1.4. If you have questions about that @Geof of myself can lend you a hand.
