Thanks for the build. I have a new 400x400 3030 corexy bot now. I'll post the build as soon as it is finished. Tolerances on the nut traps are a bit overtight, struggled to get the m3 nuts in.

Edit > I guess I should have read your BOM with more attention. M3 square nuts is what I missed.

Nice, looking forward to seeing your build!

It probably was pretty frustrating pushing regular M3 nuts into the traps... sorry about that. ;-)

Can I get the build description video for this model plss.

Well... if I had one I would've uploaded it. ;-)
Are there any particular parts that are unclear to properly build?

The laser appears to be pretty much the same I am using right now, so electronically it should works just fine (12V with TTL input). But it does have different mounting holes, you'll need a custom adapter to mount it on the x carriage.

Could I use this 3d printer mother board for this and just put different firmware on it. it only 35 bucks

The description says it is Ramps 1.4 compatible, so it should work. I used a Ramps board in my build but it's not optimal for GRBL firmware. A regular Arduino Uno with CNC shield is the better choice, e.g. this one: https://www.gearbest.com/kits/pp_362271.html?wid=1433363

how powerful of a power supply does this need

It doesn't need to be very powerful, it mostly depends on your motors. Regular Nema17 motors are rated at 2 A and driven with 12 V, so you need about 25 W for each. With the laser and the Arduino etc. you should be fine with 75 W, or even less.

Hi, nice work.
How much power does your laser diode have and is it able to cut thin wood?

It's a 1 W diode and can only cut paper and such. To properly cut wood you'd need several watts... sooner or later I will upgrade, though.

Its powerful enough to engrave or burn a pic into wood though right.
