S5 Difference between detected height error

Recommended Posts

   I'm setting up my new S5 right out of the box but I haven't  been unable to make my first print. I'm getting the error message:

Difference between detected height of both PrintCores exceeds realistic values. 

   There is no buildup on the nozzle, it hasn't extruded anything except for the set up when the materiel was loaded. Regardless the nozzle is clean and new. The glass plate is new so there's no build up there. I read somewhere I should do the manual leveling procedure. I did that twice and I'm getting the same error. I did read that:

"For active leveling to work correctly, there should be at least 0.5 mm between the tip of the nozzle and the glass plate at the start of the procedure."

  The problem is that even with the chamber being well lit its hard to tell if there is a 0.5 mm gap when the active leveling starts. Watching as closely as I can it seems like the nozzle is close to touching the glass but I can't be sure. Should I try and slip the plastic calibration card under the nozzle? 

   Its a little frustrating not being able to do my first print when the machine is new out of the box.

So that seems to have solved the problem, thank you. What does this mean? I had the lifting switch in the wrong position?

My model is now printing but oddly enough it seems like the materials are switched which is to say the brim was black PLA and now the object being printed in PVA. I went back to Cura and extruder 1 is PLA and extruder 2 is PVA. I presumed I had somehow switched the two while setting up the machine but after I aborted the print and choose the printer icon it showed correctly - extruder 1 as PLA and extruder 2 as PVA. Any thoughts on this?

Check in Cura when you select your object which extruder is set to print. You can find two icons on the left menu at the bottom. There you can switch the extruder for the object, maybe there is the mistake.

 

And then check in the right settings menu if you have selected extruder 2 for support structures.

Thank you for replying. I'll never know for sure but I was switching materials and extruders back and forth (in the right side toolbar) and I probably saved the file with the wrong materials. I say this because I tried the file again from scratch and it's now printing the right material.

Only later did I discover the two icons you mentioned on the left toolbar, which seems kind of dangerous to include. The only value of these icons (as far as I can see) would be if you wanted to switch the order of colours if you were printing a dual colour print. 

Thank you again for taking the time to help me on these issues.

Not only, I often print with an AA 0.8 core and then I put the core on the right side. Then I disable the Extruder 1 in Cura and have to switch the Extruder for the object in the left toolbar. Or if you have 2 AA 0.4 installed with different colors or materials you could decide with the left toolbar icons with which extruder you want to print.

 

I think per default Cura always selects extruder 1 for the model, that was maybe the reason why it was working for you after you started from scratch.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
