The fan wiring for V2 and V3 of the X5 (http://files.panucatt.com/datasheets/x5mini_wiring_v3.pdf) shows two fan connections each with +Vin, SW- and +5V. The notes explain that SW- means switched ground and +Vin means main power supply. Does this mean that +Vin is taken directly from the 12V? In their example, they show one fan across +Vin and SW- and the other across +5V and SW-, and the two SW- connections coming from 1.25 and 0.26.
I'm planning to connect the cooling fan to one and the hotend fan to the other. So should the config look like this? switch.fan.enable true #
switch.fan.input_on_command M106 #
switch.fan.input_off_command M107 #
switch.fan.output_pin 0.26 # <------- different from the Eclips3D config on the web
It looks like you're on the right track to me. The +Vin is indeed the same voltage as whatever you hook up to the +PWR- connection. It could be any voltage you provide it in the safe 12-30V range. In my case it's 24V, so I have both 24V and 5V available to my fans. I have the part cooling blower fan hooked up to 24V (it's a 24V fan), and the hot end fan is a 5V Noctua 40mm that goes to the 5V connection. It works great and my config file looks nearly identical to what you have in your post.
I have the Ateeg X5 V2 though and the switch.fan.output_pin is 1.25 or 2.4 for the left or right connector, respectively. The datasheet for V3 shows 1.25 and 0.26, so I think you have it right. Also, the automatic hot end fan switch off that Rick is using is great. I use it and it saves some sanity. Be sure to add the M42 command to your start gcode to make absolutely sure the fan is on before heating the hot end.
Scott, I have the V3 and hooked up my fans as you stated and shown on the datasheet and it seems to work fine. Did you get yours up and running? the jumpers in the V3 are different than the V2. I finally finished my E3D and its up and running, let me know if you have any questions.
Tony, thanks for the offer. I'm up and running fine though. I haven't been able to devote any time in the last couple weeks to printer-related things though. I need to make a post about my fan mod once I'm sure it's working well. It's nice to not have that terribly loud E3D 30mm fan whining all the time!
I'll reply instead of Scott as I am using the v3. I used this as a starting point and then made some changes. I'll attach my current config to this message in case it is useful. Wherever I remembered, I annotated my changes with a comment that starts "DAHE". I recommend reading at least the changes and ideally the whole config before you use it to make sure it's what you want. Check the thermistor setting, as I don't use the standard E3D thermistor. For a full list of the config settings, there is a page on the smoothieware web site. config.txt (21.09 KB)
Tony, I'm using the V2 and based my config off of Wasabi's 2.0 config here. You will probably be better off using the one animoose linked to. I don't remember changing Wasabi's config much besides things like PID tuning and enabling temperature-based extruder fan on/off. If it would help you or others I could post my config file. Just let me know.
