Thinking of upgrading to your Cohesion3D Mini, do I have to change anything else out for the stepper motors ?
@Robert_Selvey no you just replace the old board with the Cohesion3d mini…
Correct. Everything stays the same you just swap boards.
@raykholo note that @Abe_Fouhy supply is one that I have never seen before and may require some install tweaks. I also think the control panel is different than a standard K40?
@Abe_Fouhy pictures of everything please :).
Machine, power supply, control board, wiring, panel.
Ok will do. I’ll document it all
Does cohesion3d support power z later?
Yepp, it has 4 motor drivers so you can run a Z table and a rotary. If you want to do that now just grab the extra 2 A4988 drivers, or if it’s more beefy then you might need the external driver adapters and use a black box external driver.
Ray you’re the man! Thanks so much
Can wait to get a cohesion3d mini thats going to be my first upgrade next to air assist
Can or can’t wait? 
Can’t lol
Is the cohesion 3d mini a software upgrade where you can use an open source program instead of laserdraw that comes with the machine? I am not a tech savvy person, so I need layman terms please.
In your machine is a green circuit board (also known as card, controller). It forces you to use that crappy coreldraw type software.
The Cohesion3D Mini is a new circuit board. You take out the old one, and put in the new one. Since this is a physical item, it is a hardware upgrade.
Now you can do engravings and variable power cuts on your machine using awesome open source software like LaserWeb to control it.
How do I download laserweb3? I would like to play around with the program before the cohesion arrives to get a head start.
