Hi,
I am facing issues when I am trying to extrude the filament at lower temperatures.
I have some custom materials that should be extruded at 120 degrees. But the printer won't let me do that. I'm guessing there is a safety lock on temperature while extrusion.
Can i change the lower limit so that i can extrude at 120 degrees. Where can I change the lower limit.
Thank you all.
I got the fans issue figured out now.
Thanks a lot Ian.
I did the connections as you mentioned.
Now I can control the hot end fan with the fan speed slider in the web gui. But not the part cooling fan.
The part cooling fan doesn't turn on. How do you control them through tpre0.g config file.
The most sensible situation would be - we select the tool and the hotend fan should automatically kick in and we should control the part cooling fan through the slider or from the slicer.
How do you do that.
Excuse me. I am fairly new to this.

Hi,
I had just bought a fan for my 2nd tool head of my tool changer. I connected it and found that it's not working. In an attempt to know what's wrong, I stick the multimeter pins into the sockets and shorted them.
After going through the posts here, I found that the 1 amp fuse is blown. So I connected a jumper between the terminals.
Result : the always on fans are working.
The three mosfets look fine with no damage.
So I went on to test the pwm fans in the web control. And here is the problem.
I select the tool 0 and slide the fan slider to 100%, tool 0 part cooling fan works.
I select the tool 1 and do the same thing, still tool 0 part cooling fan turns and not the tool 1 part cooling fan.
No matter what I do, I can't turn the tool 1 part cooling fan on.
Wiring :
in the order of ports : [tool 0 hotend-always on] [tool 1 hotend - always on] [tool 0 part cooling fan] [tool 1 part cooling fan] [empty]
Where am I going wrong and what might be the issue.
Hi,
I setup the Duet 2 wifi with the duex 5 extension board. I can connect to the duet 2 access point and can home the axis but i cannot get the heaters and the bed working. What am I doing wrong. I am attaching the config file for reference.
