This is my water cooling.

This is my water cooling. A cheap “tupper” style 7 liter box with distilled water.

I like this idea very much

Claudio, I have a plug and play drop in replacement Grbl based board on its way to me. After I have evaluated it , would you like me to send it on to you to check out? Todd mentioned that you might be interested, with all the work you put into adding GRBL.

@funinthefalls ​ Is this the one from Paul?

Yup, he sent it off to me on Monday, at no charge. Nice guy!

Only problem is light can start the growth of algae, I would paint most of tank leaving a viewing slot so you can still see water level

@funinthefalls ​ Could you send me a link with some more info about the board?

@Phillip_Conroy ​​ You are right. That’s why I use distilled water and a box with a closed lid, so the water doesn’t get contaminated. Blocking light could help further.

Sure thing @cprezzi

Here is the link you asked for @cprezzi http://awesome.tech/cheap-chinese-k40-ebay-laser/

@funinthefalls ​ That looks interesting. Would be nice if I could test it to see if I can optimize LW4 for it.

OK, once I have evaluated it for a while, I will get it sent off to you.

@funinthefalls ​ Cool, thanks!
