Strange, sometimes you get insecure about the most basic … I just had to be sure.
End stops are of course both on the left side and the origin is with a K40 top left.
My $3 is 1
and my $23 is 3
it’s 100% like my settings, there must be an error in your LightBurn settings, try deleting the profile and make a new one with STM and left top origin and autohoming.
I’m here for another half hour or so
Nice that you are laser running again.
Electric noise always fills a lot here in the forum, you can read about the problem for “hours”.
I personally have bought many usb cables which all claim to be electrically insulated ect. It turns out that I have finally found a double insulated cable, put some large ferrite cores at both ends and I have cleaned up my cabling as well as possible. It is an advantage to have the shortest possible usb cable and no hub or sharing with e.g. a camera. I think a K40 in itself bothers a lot of noise with its high frequency power supply here you probably can not do much about it. What is important is a working earth connection, here it is an advantage if one’s house installation is in order and not from 1864. If possible, one’s K40 should preferably run on a group without other major electric pre-consumers because powerful power consumers such as angle grinder vacuum cleaners and the like have the bad habit of sucking too much “start” power when turned on.
I hope you get to run with your system as well as I run with mine. I am very happy with my K40, the Mini-Gerbil controller and of course LightBurn.
I have purchased a short usb and it is working now. I have to run the cable outside my k40 to the laptop in order to prevent noise but that’s no biggy and I will solve that issue shortly.
I’m pleased to have Lightburn back … I used to be a diode user with Lightburn… as it’s so intuitive.
I managed to run a raster with the pwm without interruption etc so all seems ok.
I’ve just got to get the raster settings mastered now… My first image was a bit lacking shall we say!
It’s a great start, congratulations.
In the upcoming version of LightBurn we will be able to adjust the images “live”, so it will be much easier to find the right settings before we engrave them.
I also have a 5.5 Watt diode laser which runs very well under LightBurn. I think there are many who start just like you and me. My next wish is a larger laser. They are just the physical dimensions of my workshop access which limits how big it gets.
