    If you tell it to home and it does not you will get that error you were seeing earlier from Marlin. It waits a certain amount of time for the bed to home and if it does not within that time it essentially shuts the printer down.

    When the halt happens it is instant. Say if it happens after doing a G28 then as soon as I hit enter it locks the printer.

    Here is something I find odd - if I go to the Control option in octoprint and press the Home for just the X/Y and then do M119

    Code:
    Send: N108 G91*24
    Recv: ok
    Send: N109 G28 X0 Y0*26
    Recv: X:0.00 Y:0.00 Z:8.68 E:0.00 Count X:0 Y:0 Z:6954
    Recv: ok
    Send: N110 G90*16
    Recv: ok
    [...]
    Send: N111 M119*43
    Recv: Reporting endstop status
    Recv: x_min: TRIGGERED
    Recv: y_min: TRIGGERED
    Recv: z_min: open
    Recv: ok
    Yet, pressing the Home option for Z

    Code:
    Send: N112 G91*19
    Recv: ok
    Send: N113 G28 Z0*90
    [...]
    Recv: echo:busy: processing
    [...]
    Recv: echo:busy: processing
    Recv: X:22.00 Y:23.00 Z:-1.31 E:0.00 Count X:1760 Y:1840 Z:-1040
    Recv: ok
    Send: N114 G90*20
    Recv: ok
    [...]
    Send: N115 M119*47
    Recv: Reporting endstop status
    Recv: x_min: open
    Recv: y_min: open
    Recv: z_min: TRIGGERED
    Recv: ok
    [...]
    Manually (keyboard) controlling the bed I can also go to both extremes without issue

    Code:
    Recv: X:0.00 Y:236.00 Z:8.68 E:0.00 Count X:0 Y:18880 Z:6944
    Recv: X:0.00 Y:0.00 Z:8.68 E:0.00 Count X:0 Y:0 Z:6954
    Of course I notice that the most I am getting is 236 versus the 254 I thought it should be for the Y.

    OK, I assume you can get this to happen while connected with a host program (OctoPrint counts).
    So when it locks up the printer... go to the Gcode terminal and save the entire thing to a file. You probably have to select it all the way back, copy/paste into notepad and save it. Then upload it here. I suspect we may find another error in there.

    The physical dimensions of the R1 are 17 by 15 by 18 inches (43 cm × 38 cm × 46 cm) allowing it to have a build volume of 10 by 9 by 8 inches (250 mm × 230 mm × 200 mm) -- those are the official numbers :)

    Right, but it seems to be stopping at 220x and 238y. I will try and get it to halt. It never happens when I want it to.

    10 x 9 x 8 =
    10y - 9x - 8z :) just to be clear

    Which should be 254x228x200 - right? Yet mine is stopping at 238x220x200.

    Ah, it seems whoever did the edits for the Robo updates in Marlin set the bed limits different. Might explain why my Z axis also just went off the rails when testing the limits.

    #define X_BED_SIZE 220 //--ROBO-BF
    #define Y_BED_SIZE 236 //--ROBO-BF
    #define Z_MAX_POS 230 //--ROBO-BF

    Good catch

    Before doing anything more I guess I need to flash the firmware to get the correct settings. I'm guessing that is why my first print freaked out since the print bed was smaller than the file (due to the settings) and it has thrown everything off.

    That is an excellent suggestion...

    Going to consider this one closed. Started everything over, wiped settings and so far printing normally. As usual, thank you for all of the help.
