First post here. Been printing mostly trouble free for close to 3 months now but have come across an issue after updating to the latest firmware for my UM2E+ and the latest Cura BETA.
My prints always start with the cooling fans at 100% and from what I understand, my settings are correct, but they're obviously not if the fans keep coming on instantly.
I noticed the same thing with my UMO+ and Cura 2.3 Beta. The fan comes on immediately at what seems like 100%. On the previous Cura version the fan doesn't come on until the first layer is finished. I also couldn't any settings to change that behavior.
And, for whatever reason, the default nozzle temperature for PLA has been changed to 200°C instead of the usual 210°C.
In Cura 2.3 Beta, Fan speed is gradually increased on each layer to 100% at the "Regular Fan Speed Height"/Layer.
So if you look at your gcode, you should see M106 commands at the start of each layer (from 1 to 3) with increasing values for the fan speed (0 - 255). And there should be at least 1 "M107" command before Layer 0 with no M106 commands on Layer 0.
I cannot find any way to turn off the fan until the Height/Layer is reached.
