I believe it is going to work very well. It is bigger than the chain I used for the 2x. I was barely able to get the air tube and wires in the 2x chain.

Some of the parts finally started coming in.
I started on the frame and the X gantry. Here are a couple pics.
- Frame Assembly. Still needs some work.
- L and XL Pulleys.
Getting there, slow but sure
Cheers,
Bill

Thanks for the comments guys. I would like to get the 400 Step stepper but it is a single shaft and would work for the X and Z axis but not the Y. I need a double shaft for the Y axis the way my design is going to be. Not sure it will be a good idea to have a 1.8 degree on one axis and .9 degree on the other.
I found a tube with (3) 6 foot ACME 1/2-10 threaded rods from my first CNC router project that I am going to use for the Z table lifting mechanism. Those should work out really well and make the table pretty stable.
Now to see if I can find some double shafted steppers that are 400 steps per rev.
Cheers,
Bill

I ordered my stepper drivers and chose the Keling KL-4030s . I am currently using them in the 2.x with the NEMA 17 steppers and they should work fine with the NEMA 23 steppers as well. I plan on using NEMA 23 steppers and need to decide which ones to purchase. Here is what I have been looking at:
- Keling Stepper Motors
- HobbyCNC Stepper Motors
Not sure what the difference is between having a stepper that has a 4 wire connection or a 8 wire connection. Maybe someone could enlighten me.
My 2.x steppers are 4 wire and I have a whole spool of cable that I can use to hook up steppers in the new build if I go that way. I am looking at the Keling KL23H276-28-4B NEMA 23 270 oz-in. It requires just under what the max amp output of the drivers are and should be able to move the X and Y gantries just fine. Although, I have been looking at the HobbyCNC #23-130-DS8, for the X axis, because it has a fast RPM. Just not sure if it has the torque I will need.
Decisions, Decisions....
Cheers,
Bill

Thanks Gav, I am really looking forward to this build. I just hope the sticker shock for this one doesn't kill me.
I am going to keep editing my first post and keep track parts and what they cost.

Very nice build educa, I was thinking about just using Bart's MakerSlide but noticed you and Greolt are both using linear rails. They are very expensive!
, but I took the plunge and bought
2 THK SSR15 NEW LINEAR GUIDE BLOCKS WITH 1- 55 7/8" LM Rail for the Y axis. I plan on cutting the rail in half and using 1 block on each Y rail axis. Now I have to find a 1000mm rail and block for the X axis. Any suggestions are welcome.
I also purchased the 20mm x 40mm x 1000mm extrusion that I will bolt the X axis rail to and the Pro Laser Head kit with optics. As soon as I get the X axis linear rail and parts in I will start the assembly and get some pics up.
Cheers,
Bill

I have decided to build another DIY Laser. I have had my 2.x for a little over a year now and it has performed superbly! I am getting to the point that I need to increase the power and have a bigger cutting area. I am cutting hundreds of pieces of LaserMax labels and acrylic back panels a month. The 2.x at 40W takes 1 to 2 passes at very slow speeds and if I want to keep up and save time I need to upgrade.
Anyway, I plan on building a laser similar to Greg's (Greolt's Aussie build)
http://www.buildlog.net/forum/viewtopic.php?f=16&t=1002 He did an outstanding job on his laser.
The frame will be built from 1" square tubing and 1" x 2" tubing. This laser will be fully self contained with cooling system, air assist, and fume extraction.
I have a lot to do and want to document the build so I can keep things straight in my head and get help from some of the best minds in the DIY laser forums.
DING DING, round two begins!
Cheers,
Bill
