Anyone any idea how to solve this?
Open your k40 read on board serial and update that on corellaser.
if u use multiple k40(as me) and only one notebook…write board serial on top of k40 
you need change that everytime
Engrave-> device inizialize-> device id …close and re-open software and use k40
Install a smoothie board…
@Alex_Krause where do I get a smoothie board?
Is a smoothie board a physical component or software?
@Eoin_Kirwan Physical.
Expensive?
@Eoin_Kirwan Somewhat but in the long term its worth the money
Is it absolutely necessary? Or can I do as Mauro suggests?
@Eoin_Kirwan Your call on that one.
By just putting the device Id into coral laser?
I’ll see if putting the code into coral laser works!
@Eoin_Kirwan for smoothie, you would use LaserWeb3. which is way better to use as your machine as i have heard can come with a illegal copy of the corel program.
Ok! Thanks! Where are you based? Visit my website… http://Www.handcraftedpens.ie.
@Eoin_Kirwan I’m in texas but i am just a user of the smoothieware system not a reseller.
Cool!! I may ask you more questions in the future!!
Thanks
