Hello Everyone 
,
I upgraded the printer to the Duet 2 WiFi card recently, and I'm very new to the field of 3D printing. Although Duet3D's features and community support have greatly impressed me, I've run across a small problem that I'm hoping some of you may assist me with.
I'm having trouble getting the best temperature control by fine-tuning the PID parameters on my heated bed and hotend. I've tried the auto-tune tool and read through a number of tutorials, but my outcomes are still erratic.
Here's a quick summary of my setup & the actions I've already taken:
Configuring a printer:
- Model of printer: Ender 3 Pro Duet 2 WiFi, with firmware 3.4.0
- Hotend: 0.4 mm nozzle E3D V6
- Bed: Regular glass-plated heated bed
Actions Undertaken:
- Executed the M303 command to auto-tune the bed and hotend.
- Enter the PID values that were obtained by running the M307 command.
- Carried out several prints to verify that the temperatures were stable.
Problems Experienced:
- During prints, the hotend temperature varies by +/- 2°C, which results in slight variations in print quality.
- The temperature of the bed is comparatively constant, but it takes a while to attain the desired temperature.
- Every now and then, I have temperature issues that cause the print to pause; I have to reset and restart.
I also followed this: www.reddit.com/r/ControlTheory/comments/o1g6xg/any_tips_to_tune_a_pid_temperature_mlops_controller/
I would be very grateful for any guidance on the following:
- Are there any particular options or factors that I could be missing that could aid in regulating the temperature of the hotend?
- Advice on how to heat the bed more quickly and steadily.
- General best practices that may not be included in the usual guidelines for Duet 2 WiFi PID tuning.
I've received so much encouragement from this group, and I can't wait to absorb your combined wisdom. Thank you 
in advance.
