gr5 - thank you for writing back to me. I think I have solved the problem. When I got the Buildtak flexplate system it says on the instruction card "Attach FlexPlate to magnetic mounting base. Re-level your printbed and ensure that the nozzle height is properly set." That all seemed logical enough to me since I just added approximately 3 mm in height to the glass. So I ran the manual leveling program on the printer. This required me to push on screen buttons to change the bed height and also turn the 3 screws under the bed to further adjust the bed level. After manually leveling the bed I tried to print a calibration cube and that is when I ran into problems. I decided to remove the Flexplate system from the printer and replace it with just the original glass the printer came with. Then I re-did the manual leveling and was able to print again on bare glass. It was suggested by Matterhackers that I just try the Flexplate system again WITHOUT manually releveling the bed. I tried it and it worked! Upon further inspection of the Buildtak Flexplate instruction card there are further notes that say "If your printer has an auto-leveling function and your probe is a pressure sensor, level as you normally would with the BuildTak sheet installed." In other words it seems I didn't need to do anything special to get it to work. I just needed to put the new build plate in there and the machine would figure it out. I have run a few prints on the Buildtak PEI surface and it seems to work just like my Prusa smooth sheet. The print finishes and you just pop the spring steel/PEI sheet off it's magnets and flex the part off. Print quality and leveling seem to be working normally.

I’m having trouble trying to use the Buildtak flexplate system on the Ultimaker S5. Google Photos album of this issue I can no longer print as nozzle #2 is hitting the new build surface during the initial auto leveling with the Buildtak magnetic flexplate in place. I applied the magnet to the new glass, I applied the PEI to the steel sheet, I inserted the glass/magnet sheet/steel sheet/PEI sheet assembly into the Ultimaker S5. Firmware is up to date at 6.5.1 Using the Ultimaker S5 control panel I performed manual leveling following the instructions in the prompts. I set the 1mm gap using a tie wrap and the on screen buttons. I used the Ultimaker calibration card and the knobs on the bed to set a little friction when the system prompted me to do so. I tried to print a PLA calibration cube and got this error: "Nozzle offset probe failed. Please check the nozzles and bed and try again." Also the nozzle scratched my new surface: There was a tiny amount of PVA hanging off nozzle 2 so I heated up nozzle 2 and cleaned it off with a brass brush. I restarted the printer. I followed online instructions to calibrate the nozzle switch position. I checked the capacitive sensor wires and they look fine. I tried to print the calibration cube again and got this error message: "Difference between detected height of both print cores exceeds realistic values." And the 2nd nozzle scratched the plate again. At this point I am not sure what to do. It seems the printer does not recognize the new print bed that is taller than before and the 2nd nozzle is hitting it; preventing auto bed leveling. I put the original glass back in, re-leveled and now I am able to print again like before. How can I calibrate the printer so that I can use the new bed flexplate?
