@Mario_Gayoso Lightburn is what I’m using. The cohesion took me 10 minutes to install and maybe an hour to find the sd card that came with it… dropped it somehow behind my desk.
@Adam_Hied Can you post some pics? I think I will do it! I haven’t used my machine yet. Im more focused 3d printing!
@Mario_Gayoso I’ll take a video tonight and upload it
@Mario_Gayoso my setup so far. I still have some work to do, but I’m cutting parts.
@Kiah_Connor how is cohesion working for you so far? Any other upgrades on your machine?
Warning: MANY WORDS.
Cohesion3d & Lightburn:
@Mario_Gayoso Fantastically! It’s a huge leap in convenience and quality. And it doesn’t turn off usb connection every time power fluctuates slightly (i turn on a fan in my office and it used to interupt my jobs) Lightburn also blew my socks off. I’d consider it worth it just for allowing you to use Lightburn.
They’re not kidding when they say it’s quick and easy to replace. Just be sure to read the instructions, and be ready to hit the kill switch when you first test (it might home to the front corner instead of the back if you have things the wrong way around, and make horrible noises because there’s no endstop there to stop it! Be ready)
Upgrades:
I’ve just finally swapped my K40’s bed. Was using basically chicken wire before. Now I’ve got some threaded levelling feet (https://www.admerch.com.au/product/m8-steel-fixed-levelling-feet-lvr089/, cut down to size with a bolt cutter) on the base holding up metal honeycombed expandable mesh (purchased on ebay from a german fellow https://www.ebay.com.au/itm/132697048886?ViewItem=&item=132697048886). No more worrying about poisoning myself with zinc from galvanized metals, and technically height adjustable if I can be bothered.
I’ve got air assist - An aquarium air pump provides that - I’ll link the model when I get home in case anyones interested - I’ve found it to be a much better option than a compressor - quiet and consistent. Slightly pricier to get a model with enough power though! This cost me over 150AUD.
I’ve also 3d printed an air assist nozzle (https://www.thingiverse.com/thing:2421971)
I’ve replaced the provided water cooling aquarium pump with a grounded australian one. Looking at some non-conductive algaecide options though so I don’t have to change water as much.
I’m currently looking at mounting options for a webcam for the cool camera option lightburn has.
I’m redoing my exhaust system hopefully soon. I’ve had a new vent shroud delivered that apparently fits the k40 a lot better - will get rid of the old k40 bathroom fan - Right now it runs to a bouncy castle blower that I pick up and place outside my office window whenever I want to cut. (I’m just overwhelming everything with so much air pressure that it can’t even think of leaking acrylic fumes at me)
I’m off at a LAN party this weekend, but some time in the next few weeks when I have some free time I might put up a video of my janky Australian setup.
@Kiah_Connor Wow so much help!! Thanks so much!! I look forward to see this video! I will check this links and start working on this project. I haven’t cut anything yet with the machine as it is. I’m afraid to cause a fire or something like that.
I will get the controller, lightburn a new honeycomb bed, air assist, exhaust, vent and fan and even maybe a chiller… I realized that buying the more expensive machine at the end was cheaper than this one, but the fun is in the process of upgrading it!
I look forward to seeing your video Kiah!
Thanks again!!
Even with every conceivable add on and modification, I doubt you would come close to a third of the cost of a name brand.
@HalfNormal 100% agree. I’ve got $1500 into mine. With replacing the cw3000 with the 600watt light burn chiller, z table, air assist, LightBurn, cohesion 3D, glcd, better optics, external power supply, and upgraded exhaust.

Varaious wires, switches, airlines, and exhaust tubing as well.
@Adam_Hied very nice job documenting your upgrades.
@HalfNormal thanks it took me a few weeks getting it setup. Really having fun now.
@Adam_Hied THANKS A LOT! what an amazing help!! keep it up with the youtube videos and your projects! I’m sure they wil help lots of people 
… so you got the 600w water chiller? how does it run?
@Adam_Hied I just checked all the upgrades and put them in my shopping cart. They are many items that are Z table related right? which ones are those? the last one for example and what else?
@Adam_Hied what do you think about this? https://www.amazon.com/gp/product/B00EFFOF0W/ref=ox_sc_act_title_1?smid=AGJOB9QIKR6CC&psc=1
@Mario_Gayoso the aluminum plate, the honeycomb grid, and the 24volt power supply are for the z table. You will also need 1” square tube 1/16” thick if you get the holes mods z table. Give Randy a call or email about the z table he can walk you through it. It’s not hard to build but did take me a few hours. That being said this isn’t the first time I’ve messed with cnc machines.
I wouldn’t get the grid you looked at if you get that z table. The overall size may not be correct.
@Adam_Hied at the moment I’m not looking at getting the Z table. I got the chiller, duct, the 12 volt speed reducer, the 12 v step down (assuming for the fan for the duct), cohesion 3d mini, new lenses, chain, fan, air assist, air exhaust hood and some other things. Now my focus is into GROUND the machine the right way. What did you do with yours? So many scary videos about death!! My wife is concern haha.
@Mario_Gayoso I just made sure it was making good contact. Then Verified the ground on my outlet was good. For sure watch the YouTube vids, but If the machine you get looks like it’s in good shape like mine you’ll probably be all set. Mine was even properly aligned.
Oh I did buy a fire extinguisher…I think something your cutting catching fire when you’re first trying to figure stuff out might be the biggest problem.
Also, the z table is probably my favorite thing. I can go from cutting paper for wedding invitations to engraving a knife handle and in seconds with just a few clicks.
Did you get an external 24 volt supply and external stepper driver?
@Adam_Hied I will post everything I got! I will need your help man!! Haha I’m thinking about that table you mention. I got the honeycomb bed but maybe I should get the z table.i went all in and got the chiller too. I also cut the exhaust and I did a pretty decent job.
@Adam_Hied this is how I cut the duct
