I have a Snapmaker 2.0 with 40 Watt laser where the cooling fan and the heating bed use the same port. It is abit of a pain in the but to unplug and plug. Does anyone have a solution, like a switch or is there another port available?
You donât use the heated bed with the laser. From that point on you must unplug the heated bed for using the laser.
It will be easier if the air assist can plug in in the bus extender. Normal are both outside de enclosure.
I understand i must swap plugs, i was hoping they had a work around, as i am not to happy with this type of connector, and i have been working with electronics boards for 40 years. Even with all my experience i was able to plug one head in backwards an damaged the controller.
Are you saying i can plug into an extender bus? Is that a separate part?
For me was that the logical solution. But it wonât work that way. 
I havenât problems with the plugs. Always the push side at the hole side of the connector. Bad is that not al the tools have the same connector direction. 1,6W laser and original CNC are 180° difference with laser 10W, laser 40W and 200W CNC. Double extruder is 90° difference.
It must be power load related, seems to be only 4 wires so I may get some cables and make a switch box. Unfortunately or maybe fortunately they are different pin and key configurations.
Another project for the list
I found this and was wondering if it would support the bed and air

I have the Can hub and I hoped I can connect the air assist to it but it donât work. Emergency stop and air purifier are connected with.
I wrote to the factory specifically on the HUB
They said the HUB would work and I am verifying

Thank you for your quick response and just to confirm I can do this as it was not noted in the documentation
I assume I cannot run both at the same time
Also, I think there are other open ports on the controller and could they be used?

For me it donât work. M9 makes no difference. The air assist works at the moment I plugged in the hub.
At the left the connection with the enclosure, like provided by the manual. Second the connection with air purifier. 3de the air assist and at the right the emergency stop.
You can hear the air assist at the moment the SM is booted.
An hub for the heated port is not my choice. Or the hub is into the enclosure or out. If out, the heated bed cable must every time through the enclosure hole. That isnât a progress.
I do not have an enclosure, but my controller is in the back. I will wait to see what they say.
Will the 40W work without enclosure? By artisan not. If I burn through 5mm MDF, the enclosure is completely filled with smoke. First I havenât my airpurifier connect with an exhaust to outside. The whole garage smell to smoke. With a smoke alarm 2 meters from the laser, it is good there is an enclosure.
In winter great to heat up for printing.
I guess I am old school, was looking at arc welding when I was a kid. I am only cutting acrylic, tried some 1/2â and not much smoke.
I guess the 2.0 does not require an enclosure. I am about to redo that location and may consider an enclosed and a vent.
I also work on Fire Alarms for a living and if it set it off I would log it as a test
