I’m curious to hear what you all are using for air assist, and also how that relates to what machines you have.
For example, I have several K40’s including a K40D. I have been using the K40D for a lot of my production work for the better part of a year now. I also have a larger “50w blue and white” that I got secondhand and fixed up last fall and still need to install the HVAC ducting for exhaust.
The K40D came with a bigger air pump that kept overheating because it was only allowed to push very little air compared to what it could/ was meant to do. I had a small DC air pump that I put in place that worked well, but I got a bit tired of the noise and having to plug it in and out every time (and sometimes forget to).
A number of my friends with bigger lasers were talking about how good and quiet certain compressors were so I just got a California Air Tools 8010 and am working on the air setup to have it drive 2 (or more) lasers air assist. It’s a pretty quiet unit and the consistency of airflow is supposed to lead to unbelievable cut edge quality. I’ll have to see for myself.
Anyways, in this case with a compressor, I’m going to need a solenoid valve per laser, driven by the laser controllers, but if I was sticking with an air pump, then I’d need a relay to drive it from the controller, and AC/ DC would depend on whether the pump was 12/24v or AC driven from 110v/220v.
I am curious what you all have. These are all good details to know, and pictures are always a plus
