If the file does not load try rebooting your computer. For trouble shooting you might want to try loading this test SVG file: k40_whisperer_test.svg.Ĥ. After you have deleted any text in the "Inkscape Executable" field try loading an SVG file. If there is anything in that field delete it then click on the "Save" button next to "Configuration File" so the setting is remembered for future K40 Whisperer sessions.ģ. Generally the field for "Inkscape Executable" should be blank. Look at the "Inkscape Executable" entry field in the General Settings window. Make sure you have Inkscape installed (Inkscape Version. Here are a few steps to try to resolve this error:ġ.

Entering a path to a desktop shortcut is a sure way to get this error. The most common problem that causes this error is that an entry has been made in the "Inkscape Executable" field that points to a file that is not an Inkscape executable. This particular error occurs if K40 Whisperer found the Inkscape executable and it failed to run. When you get an Inkscape execution failed error it indicates that something went wrong when K40 Whisperer tried to run Inkscape. K40 Whisperer runs Inkscape in the background to generate raster data for SVG files. How do I fix an "Inkscape Execution Failed (while making raster data)." error? If it works using sudo then it is definitely a permissions issue. Try running K40 Whisperer using sudo (or as root). If you are running Linux you might not have given yourself the correct permissions to access the USB port/device. What Causes "USB Error, Laser USB Device not Found" error? It seems that Laser Draw (LaserDRW) is less sensitive to the timeout issue so there is probably some improvements that could be made to K40 Whisperer. If the job runs through to the end that might indicate that the power going to the laser tube is involved in the timeout problem. If you are up for an experiment you could try running the same job that keeps failing with the laser enable switched off. A couple of potential sources of interference are arcing at the laser tube caused by coolant that is too conductive or a particularly noisy/dirty (electrically speaking) power supply. My theory on this is that there is some sort of electrical noise or interference that is causing the loss of communication between the computer and laser cutter. Some people say a better USB cable helps. Some people find that switching the USB port helps. Why this happens for some people and not others I do not know. The timeouts error is an indication that the computer has lost its connection to the controller board.

#WH40K KLIB DRIVER#
The driver installation procedure is located here:Īfter you have installed the LibUSB driver Laser Draw (LaserDRW) will not work unless you remove the LibUSB driver and reinstall the default driver.
#WH40K KLIB INSTALL#
(Laser Draw uses the default driver.) In order to use K40 Whisperer you need to install the libUSB driver.
#WH40K KLIB WINDOWS#
The driver that K40 Whisperer uses to control the laser is different from the default driver that windows installs. Why do I get an error that says: "USB Error: No backend available (libUSB driver not installed)"? This video is very helpful if you are just starting out Making a Design in Inkscape for K40 Whisperer To start an operation you need to click the "Raster Engrave", "Vector Engrave" or "Vector Cut" button. You click it to pause a currently running job then you confirm if you want to stop the job or cancel to resume. It is a red Pause/Stop button that never changes color. Why is the "Pause/Stop" button stuck on red? Some additional information on colors and text can be found here: To engrave a fill you need to use raster engrave. If the fill color is set to red or blue it will not result in vector features. Only Stroke features can be vector cut or vector engrave. Double check your colors if the items are not recognized.Ģ. The colors can be incorrect by a value up to 9 so (246,9,9) will still register as vector cut. The color for vector engrave should be (0,0,255). The color for vector cut should be (255,0,0) red=255, green=0 and blue=0.

Generally there are two reasons that items are not recognized as vector items.ġ. Why is my design not recognized as vector cut or vector engrave?
