Motors and Frame

Because I based my rover on rocker-bogie platform with skid steering drivetrain (think steering a tank, turning is accomplished by rotation of one side in one direction and other side in the opposite) I needed 6 […]

First look at Boss Laser LS-1630

New Laser machine arrived on Tuesday!!!  I’m jumping from joy as this is one serious pieces of equipment!  My 50W eBay laser looks like a tricycle comparing to this monster.  While it has same 60W tube (I’ve upgraded my eBay laser a while back), Boss Laser has much large cutting better and better overall build.  This is Generation 5 LS-1630, which from what I’m hearing was designed from ground up by Boss Laser company.  Comes with full one year US support too!

I decided not to call this video unboxing, but rather a first look, because I already un-crated it 🙂

DIY Pin table V2.5

A while back I wrote about making pin “vector” table for laser cutter (here and here).

There were some issues with it that I discovered later on.

First issue with rivets height.  I don’t know how I missed it by some of them had huge variation, resulting in very uneven distance from laser head.

Second issue what with […]

DIY “Stud Table” for laser cutter for under $8

DIY pin table that I made a while back seemed great at first, but then I realized that not all rivets have same height. I only measured few from first box, and they looked to be same height, so I didn’t check others.  I didn’t really notice this until recently and got a bit upset.

So meet DIY […]

How to add ammeter to 50W Chinese laser cutter from eBay

Ammeter add-on was on my to do list for a long time. It’s important to know what current is flowing thru your CO2 tube so you don’t shorten it’s life. Ammeter measures current and in case of this SH-G350 machine you’ll want ammeter rated in the 0-30 or 0-50mA range because most CO2 laser tubes run under currents under 25mA.

60W laser upgrade

It’s no secret that my SH-G350 laser machine, a.k.a. 50W eBay laser cutter, is not really a 50W.

Yup, it’s one of the biggest scam on the eBay.  What you get is actually a machine with 35-40W watt 800mm long CO2 tube, that’s being overridden with higher current to work like 50W.
