All of a sudden my Robo r2 is not able to make it past the 3rd bed height check point it does before starting a print up. It makes it through the first front left corner check it does the second one in the front middle of the bed then it moves to third position and just raises the bed far beyond the height it has just done for the last to checks and jams the print head into the bed which then outputs a printer has lost connection error on both the printer screen and in Cura- I am printing with OctaPrint. I have no idea what is wrong, how it happened or how to fix it. Please help! I am about to just buy another printer from a different manufacturer given the parts support from ROBO. But I have loved this printer so if it can be saved I want to obviously. The same thing happens when I print direct from the printers internal memory, or from thumb drive. I have made zero changes to the printer that would have caused a failure like this. I have re leveled the bed and recalibrated the z height multiple times already. Restarted everything multiple times. Just not having any luck.
