![]() Here is a link to the old instructions.ĭownload the installer file from: K40 Whisperer Download Download the file called The steps outlined below are improved over the previous instructions that required the use of Zadig. For Linux and Mac additional work will need to be performed by the user for proper installation. These dependencies are resolved on windows by packaging them in the pre-compiled executable version of K40 Whisperer. However there are a lot of dependencies that need to be satisfied in order to successfully use the program. K40 Whisperer is written in python so it is possible to run it on Windows, Linux and Mac. If your controller board says Moshi anywhere on it it will not work with K40 Whisperer. K40 Whisperer only works with controller boards made by LIHUIYU. You will need to select the option to install the USB driver in order for K40 Whisperer to communicate with the stock K40 controller board. ![]() Included in the installer is a USB driver installer. In order to make using K40 Whisperer as simple as possible I release a windows executable and installer. Here is an instructable of a guy talking about how to work his files that I used all the time:Īnd this guy's discovery about laser alignment hits home for me, I totally missed this before.K40 Whisperer USB Driver Setup K40 Whisperer Setup (For Windows) Also consider an air assist or your just going to put out fires and get mixed results when cutting and engraving.I got this one here for my K40, and a new lens which helped (I scratched my original lens when installing the new air assist sooo be super careful!!!) So I would avoid MDF until you get more hours in, and graduate to MDF. Only now have I tried to cut plywood with an MDF Core and boy did I turn that into charcoal with a 60watt laser. I have been cutting for a while now and agree 100%. ![]() Adding that would be my first recommended upgrade.Ĭalley479 has it right on the money. And anything that smokes will be harder to cut without air assist. Card stock cuts great for me at 50mm/s at 50% power. Though some plywood may need a little slower for consistency. I've found ~3mm plywood and acrylics cut well at about 6mm/s at 40% power. You just have to find a supplier that can consistently get one that works well for you.Īfter you get your hardware tuned, you'll need to experiment with speed on different materials. Some people attribute this to the glue, but it's next to impossible to find that specified. Plywood cuts ok, but I've had some batches that needed an extra pass. It tends to scorch and catch on fire if you go to slow. I recommend two passes at a relatively fast speed vs going slow. But again, it may come down to composition, so try some different kinds. Especially corrugated since the two layers are so far apart. I've found cardboard to be a little difficult as well. But it may be more about the composition since I've seen others cut it ok. Something about the glue doesn't work well for me. It cuts well at high speeds.Įven with a well tuned machine, I've not been able to cut mdf well on mine, though I haven't tried much. I use a lot of construction paper or card stock (<1mm) to test my designs or when tuning my hardware. When I upgraded to an air assist head, it moved my focal point up 10-15mm because the lens sits much higher than the stock head.įind something that works well to do some initial testing. But you'll need to know where the lens sits in its mount. Most k40 machines come with a 50.8mm fl (2"). You may have to try some materials at different heights to figure it out. So take a look at that if you've followed all the other adjustment procedures.Īlso make sure you know your focal length. So no matter how much I tried to tune the mirrors, one corner would always be off. But one other issue I ran into was that my tube wasn't square in its mounts. ![]() Mirror alignment is one of the most important things, and you'll find many articles on how to accomplish this. But you need to make sure your mirrors are tuned and you know your material height before you start testing new material. Finding the right material is quite challenging especially at first. ![]()
