@cope413 Just to recap, when we started, the Z motors were dialed too high and acting up. Not sure if we determined why this was set this way...
We then re flashed the firmware. PID calibration obviously is not working or providing us reasonable values...
My first calibration gave me
KP 7.74
Ki 0.19
Kd 79.95
My second calibration gave me
KP 9.29
Ki 0.41
Kd 53.00
These kept the hotend 20c below the set temp no matter what I set it at.
We then bumped those up to your suggestions (still not sure why a self PID calibration did not give us reasonable values)
Now its getting higher but staying 3-4 degrees below set temp and fluxing heavily between 3-4c below set temp. This is with the nozzle even at HOME Z up and away from the bed.
So what we still have is a lot of unanswered questions on why this specific printer is acting so strangely...to begin with.
Spoke to David Gaylord and at this point, we both are just not sure why we are still messing with this printer when it clearly had issues early on....
