Calibrating the FLSUN QQ-S delta 3D printer without a sensor or substrate!
I had the idea to get rid of an unnecessary component—the plate with the conductive layer.
Why not calibrate the table directly against the substrate?
By the way, one of my subscribers had asked this question earlier, but I didn't pay attention to it at the time because I didn't have time to figure out how to implement it.
But in this situation (NOT SELF-insulation), there was something to think about.
The solution was obvious!
And here's the implementation for your consideration!
Required conditions:
remove the plastic from the nozzle so it doesn't leak (it will interfere with contact with the table)
or slightly reduce the nozzle temperature, at which point the plastic isn't leaking, but the nozzle is already practically in working order and won't increase with additional heating, thus preventing the gap from "going away"
heat the table and plastic. Believe me, there's a gap between the damped table and the nozzle and the heated one.
It's all so simple, right?
I'll note that touching the nozzle to the table, as long as there's contact, won't damage it!
Good luck everyone!!!
