Broken Z-Axis Connector

That is the new z mod they are putting on the later printers that are now going out. There is a simple and easy fix but ti requires drilling one hole and the ROBO guys are held responsible if things go wrong and so do not recognize it or suggest doing it all. That being said it is a very simple fix infac it is on my maching now instead of this mod I did mine before this "approved" came out.

The z axis forms an "L" on both the front and back of the part the vertical part of the "L" is where the rods go and the horizontal part of the "L" is between the vertical part and where the x axis rod connects to the z axis part. the mod is to simply drill a hole in the horizontal area between the vertical part and where the x axis rods go straight down I am not sure what bit size to use for tha thole but make it barely smaller than the screw so you can thread it with the screw the reorient the z stop so that it is under the screw. Try and position the screw so it hits the middle of the switch so you can have adequate adjustment options

Here is a pic of mine

it is the same thing as what you have except they added a section just for it so you would not have to cut or drill into the robo

AGAIN:

ROBO WILL NOT RECOMMEND OR APPROVE THIS SO PROCEED AT YOUR OWN RISK

but it is a rather easy mod to make should take about 5 minutes total

 

Are you the bed or on glass
and how was it stuck down
there is a set of tools the Printed _Solid came up with a while back one of whici is a cricut spatula it works really wellto remove blobs and prints but this is usually done on glass not on the actual heat bed. If you are on glass this would work fine if not the using it carefully can get it removed but you have to be careful and not cut into the heat bed. There are not many solutions for PLA but if you do not have the cricut then you POSSIBLY could use some MEK but be very carefuly and test it on a small edge ar corner and make sure it does not react with the heatbed surface.

Here is the list of tools in the post on this forums with associated links
