Pics of the X axis. I have used a prebuilt torch height unit, as I have this one here. Will have to chage the DC motor to a stepper. Ive included the Torch, Camera and scribe. All 3 can access all the the table cutting area. In the second pic is a vew with the covers removed. Again Ive added a fan and filter to the the cover plates

Funny, I bought one of those lifters recently. It was supposed to have a stepper on it but it turned up with a DC motor. You reminded me I fitted the stepper (It had been spot drilled for a Nema 23 motor) and modified the wiring earlier in the week. I also modified the torch holder so its closer to the lifter but never finished the job. Been no time for play this week!

Also, have a think about the camera wiring. The maximum USB cable length in the spec is 5 metres and you'll need a lot more than that. You]ll need an extender of some kind. Thats why I think a crosshair laser pointer is a better idea.

Looks great.
I am a bit worried about your gantry ends as they may flex under inertia on X axis moves.
I think it It needs something to stiffen it up. Can you fold the edge over or attach another box member along the angled edge?
 

Thanks Rod. Have attached a couple more detailed pics of the gantry ends. Beeen trying to build as light as possible but in saying that have not got to do any structural testing in solidworks yet. 

You probally could not the see the angle bracket in the underside in first pics or get a good view of the braces.

Let me know if you still have concerns

Same here only time to work on this is at night, flat out building and shipping orders plus have half a dozen R&D projects for new products to get finished. 

The unit I have here has the new style torch holder not the one in the pics. The new one allows you to adjust the angle in in the x and y planes and retains the collision detection

Ill add a powered extension if needed. I can also go for the WIFI camera and supply it with 5v power. Also have plenty of room for some pointers if needed. I wanted to have the provision of adding scananything at some point.

The workshop is rather large so at worst ill use the camera to view whats gooing on remotly. Might even add it to the camera system I have in place here.
