    Hello all, hoping someone can help. I have a robo 3D R1+ and using MatterControls. All of a sudden all of the movements and speeds of the printer are doubled. When I move the extruder 10mm, it moves 20mm but says it only moved 10. Also I can tell the speed is a lot faster. This is when it's printing and when I'm manually moving. Anyone have any ideas?

    Did you "upgrade" the firmware?

    Try restarting the printer from a complete power off.

    Do you mean just turning it off at the switch? I've done that.

    Well, if you can get the GCode console up in mattercontrol (http://wiki.mattercontrol.com/OPTIONS/G-Code_Terminal)

    Try manually commanding a move and see how far it goes.

    G28 ; home all axes (X, Y, and Z)
    G91 ; use relative positioning for the XYZ axes

    now ...

    G0 X12 ; move to 12mm on the X axis

    Did it move the X axis 12mm?

    G0 Y12 ; move to 12mm on the Y axis

    Did it move the Y axis 12mm?

    If not, how far did it move? (you can of course swap in your own value of travel distance as long as it fits on the bed size)

    Either the slicer is misconfigured or the printer. You need to check which.

    P.S. GCode is case SeNsEtIve :)
    So G28; is not g28;

    Okay so when I did the G28, instead of the extruder going to the left all the way, it went to the right all the way. In MatterControls, you have those buttons that home axes, when I use those, the extruder goes to the left all the way. so starting with the extruder all the way left, I did G91 then GOX112 and the extruder went all the way to the right, my bed is only 225mm wide and it also went very fast. Interestingly, the other two axes behaved appropriately.

    I am stumped if there where no changes to the configuration or firmware updates or hardware replacements, It shouldn't change the distances travelled all by itself. What does the printer configuration look like in MatterControl?

    Yea, something seriously is out of whack if the HOME command fails completely. Get the answer to @WheresWaldo question ...

    Also it would have been: GO X112 with a space in there :)

    Do you mean under Options -> EEProm? Interesting, yesterday was the first time I looked in there and it came up but now when I try to get in there it gives an error of "Warning - No EEProm Mapping".

    Does MC have a terminal screen? If so you could try M503 and copy/paste the results here?

    See, that looks correct.

    <-echo: M92 X80.00 Y80.00 Z800.00 E723.38

    80, 80, 800, 723.38 those are all default steps/axis and correct for an R1+.

    I'd try another host program just to rule it out, but if the GCode commands directly from the terminal were off it is the printer.

    Could my board in my printer be messed up even though I'm not getting an error?

    Something is messed up :)

    I am a bit stumped because what you are seeing is not a normal failure mode.

    I'd still say try different software on tehe computer side (something other than MatterControl) just because it is easy, but your testing seems to totally rule that out.

    Almost invariably when the printer hardware (motors or electronics) die things either stop completely or become intermittent. However... yours is still responding but wildly off.

    I would suspect the Arduino board itself is the culprit (not the RAMPS). Under warranty you need to be hooking up with Robo to sort this. Out of warranty I'd say swap the Arduino and reload the firmware into the new board. If Robo didn't use a slightly customized RAMPS I'd make that the first thing to swap, but for the R1+ you would need to use this thread (http://community.robo3d.com/index.p...and-rewiring-to-make-generic-ramps-work.8356/) and that is a bit more works so swap the Arduino for a start (and reload the firmware into the new board).

    Thanks everyone for all the help! I think I'm down to it being a problem with my board. My LEDs and fan for cooling the layers are now dead too. I'll get a new one and try!

    If it is an R1+m @Geof has a wonderful thread outlining how to replace the custom Robo board with a generic Arduino / Ramps combination. I suggest looking into it because those combos are cheap and you can always buy one as a spare for less than it cost for Robo to supply their board.

    Thanks for the suggestion! I have a physical disability that effects my fine muscle control so there's no way I could do that! And the people who take care of me are nowhere near smart enough to do it. Getting the new pre-assembled board is going to be fun enough explaining to someone how to put it in!

    Hey Brad,
    The generic ramps swap is quite easy. Its really just moving connections around, but I completely understand if you'd rather get the full board from Robo. Keep in mind the R1 series is discontinued (at least for now) so I'm not sure how much longer those kind of parts will be available. May want to pick up a couple.
