@owend I sure have, it is a nice guide that tells you how to connect a DHT22 sensor.

Controlling Filament Dryer with DHT22
I have created a filament dryer heater that I need to run 24/7. I also would like to drive this heater off of humidity but from reading on here it doesn't look like I can do that. I currently don't use a heated bed as I let the heated chamber heat the bed up. So I have mapped the extra heater with M140 and using the temperature from the DHT22. Does anyone know of a better way to control this? Is it possible to control it by humidity? Thank you

RE: Nema 17 intergrated servo motor possible?
Your blog is phenomenal! I have been trying to find information on these for about a month. I finally got them working but always wanting better.

RE: Nema 17 intergrated servo motor possible?
@rabbit I set the rigidity of the motors (Parameter P01-03) to 22.
How do I change this parameter? Do I just buy a cable and download a program? I too am getting a salmon finish to my prints. I have a 2:1 reduction in the Y but not in the X. I would like to try to reduce the effects of this if possible with tuning. If not I may look into other motors or possible mechanical reduction.

RE: Closed Loop Motor Setup
@toastinator Yes I am using Duet 3 with 3 expansion boards. I run them on x,y and z axis.

RE: Closed Loop Motor Setup
I run these same motors on my printers, took me a long time to get them working correctly but I think I am close. I was getting inconsistent layer shifting until I started going crazy with the T parameters.

RE: Chamber heater hysteresis
I am in bang bang mode are you suggesting switching to PID/PWM mode with a super low frequency?

RE: Error Parsing Response
I was running 3.3 beta1. I also have a 3.3 beta I’m not sure if they are different or not. I went back to 3.3 beta and am still getting the same parsing error.
