Setting up your k40 laser

First thing to do before you try anything with your laser is to check the electrical wiring in the machine – see this article about Electrical warning.

Please note
This guide is made from the standard configuration and products coming with the machine when you order it.
For more information about upgrades and optimizations, check out the other categories to the left.

Parts delivered with your machine

– The machine itself
– Exhaust fan and hose
– Water pump and tubing
– Manual with CD and USB-dongle

Some machines arrives with a tube of silicone, this is used to isolate the connectors on the laser tube when/if you need to change it. You do not need it for initial setup.

First step – software

On the CD delivered with your machine you have the software needed.
LaserDRW and CorelLaser is attatched, i would suggest using CorelLaser, less bugs and problems.
First install Corel Draw included on the CD, after that install the CorelLaser addon and you are done. See first run to set up your software.

Aligning the mirrors

This is one of the most important steps, and also the one who will make you say words not written in the bible.
Prepare good for the alignment with time and temper, hide the wife/man/kids and have some alone time, this will test your temper to never before seen levels 😉

Exhaust

Mount the exhaust fan on the back of the machine, use tape to make it air tight to the machine.

Watercooling

You need the parts delivered with your machine, aswell as a tank to keep your coolant in. Suggested is 2-5 gallons. The more the merrier, small tank will get you above the preferred temperature quicker.

    This site should be mentioned as standard within every variant of the K40’s instuctions.
    My advice to any new user would be to read, read, and re-read the articles available on this site and those of the Facebook sites that the owner of this site frequents.
    The value of the members knowledge combined is a tool that all K40 owners can tap into, and should do.
    As for myself, my K40 remained in its box for over a week whilst i digested the articles and tips made available here, and iv’e had plain sailing since.

    I’m considering the purchase of a K40 in the near future, and am impressed by the amount of excellent information on this site.
    Before I order the unit from China, I have a few questions to be sure I don’t make any fundimental mistake:
    I intend using Inkscape with Whisperer for the software, but read that the Whisperer only functions with particular K40 controller boards. Is this true, and if so how can I be sure the K40 I order will be compatable?
    There seems to be a number of different K40 machins for sale, varying from £320 to £650, some marked as “New Model” and others not, both red case and blue case. Can you point me at an appropriate unit, as the descriptions seem to be very similar for all machines?
    Is there available a complete kit of upgrade parts that would bring the basic K40 up to a good and safe standard?

      If you order a K40 with support for CorelDraw, CorelLaser or LaserDraw it will work with Whisperer. Keep away from MoshiDraw and LDDraw supported machines. Check out the article about the K40 machines, some are K40D and worth a bit more. https://k40laser.se/about-k40/

    I have had problems with the process of aligning the laser. In fact, the recommended process has caused a failure in the mirror to where the laser actually burned a hole right through the mirror. The problem is with the recommended process, tape is used to cover the mirror so when the laser is pulsed it will make a mark on the tape so you can see where the laser needs to be adjusted. Well when you do that, the laser burns the tape and it deposits burned paper and glue on the mirror. It ruined my mirror because I could not clean it good enough and after my alignment on the first run, the laser destroyed the mirror. I cannot understand how this doesn’t happen to everybody that uses this method. No matter what kind of tape or post it notes I used, it still messed up the mirror. The laser will burn the paper and mess the mirror up every time. Is there another way to do this or am I completely missing something?

      Put a coin behind the tape to protect the mirror.

        Wow. Never thought of that. I feel like a dummy! I guess sometimes you can overthink a problem and it takes another set of eyes to help see the obvious! Thanks.
