PID control

Postby Andy Cohen » Sat Jul 15, 2017 11:53 pm

The one thing about the Raise3D that drives me NUTS!!! is the way when I load or unload filament or sometimes at the start of a print the PID control stops the temp increasing RIGHT BEFORE it's supposed to and drops then starts upwards again adding time to the operation. This is unnecessary. PLEASE tune the PID control!!!!

In case you missed it, the new touch LCD updates let you autotune PID and save the values now.

The absolute latest update for the touch is being tested but is linked here viewtopic.php?f=2&p=16554#p16495

Otherwise, the current "official" update located here has the PID and steps per mm function.

Notes specific to Raisepacks are here https://www.raise3d.com/pages/touchscre ... ease-notes

It was discussed here viewtopic.php?f=3&t=1895&p=15680&hilit=autotune#p15591
The majority of the update comes in the “Settings” Menu. One of the major bugfixes we have comes in the form of the PID autotune feature. This feature is to help those printers whose printhead heaters cannot reach the desired temperature. An example of this issue is as follows:

Print head temperature set to 215c, printer reaches set temp after about 1 minute.
Print head temperature set to 260c, Printer reaches 250c and holds temp for more than 2 minutes. Printer is unable to reach 260c.

With the new Auto Tune function the user can select a desired temperature and calibrate the sensors to reach that more accurately.
