Hi John. Is this a different style than the machine I saw at your shop?

Hey John!

Yes it is. You asked me about the mockup of the drive that I had on the workbench. Do you remember?

You do nice work.......jb

Thank you...

[Boogiemanz1]

yes, I remember, pretty slick. I have gotten more parts in, soon the work will begin.................jb

[tulsaturbo]

Hi John. let me know when you get that going. I'd like to see it in action. as soon as the rest of the parts get here I'm ready to start on my table...........jb

Hey John,

I made a new control box yesterday to keep the THC together with the rest of the electronics. Cut some metal this morning to test out the THC and everything worked great!

awesome stuff! Mailed you...

I am looking to start adding the pneumatic lines to my plate marker. Does anyone have leads or links of where to go to purchase the lines and fittings similiar the ones shown in the photo attachment? TIA!

Try this link, look to the left and click on air tab, also many other items for machine building

Also a company called Airdraulics the have anything you can think of for what you are doing.

I am planning a build myself using the plasma bot kit gathering info right now.

Since I did not have anywhere to put my big 4.5" fan within this new box, I had to find an alternate method for cooling.

So here is my recent upgrade to the control box which now includes an aluminum heatsink plate with fan cooler on the G540 controller and an externally mounted heat exhaust fan for the box itself.

Plasma Spark Curtain

After testing it out this weekend, I am very satisfied with the results. All that is left to do now is to mount it permanently...

Looks like a good solution--what kind of fabric is it?

[cobretti]

JB that is exactly what I need in my limited space to stop errant sparks from lighting something up

It is a Flame-and Water-Resistant Cotton Fabric

I wanted a simple 4th axis for pipe cutting so I opted to make this simple direct drive unit rather than the traditional gear reduction drive unit. Shown below mounted on my RouterBot for testing purposes...

Hey Tulsa Turbo, any more comments since you installed the torch height control? How is it working? are you happy with it? If I understand it correctly, it replaces your touch and go right? Have the cuts been much cleaner?

[vdubjim]

was just poking around your site i saw: DIY EZ CNC Ver.2 PlasmaBot 4.0 Gantry Kit.

Seems way easier than the aluminum rails.
Cons?

tulsaturbo,

Do you have a parts list for the rotary axis components? Mainly where did you get your bearing, chuck and the motor to chuck shaft?

Thanks!

I am very happy with it once I got certain parameters set correctly. The touch-n-go is still required. Cut quality depends to a high degree on the distance between the torch tip (nozzle) and the surface of the sheet being cut. By maintaining the correct cut height with the THC, it has virtually eliminated beveled edges.

PROS: A simple alternative to building a cnc machine and get it up and running quickly. Just as accurate as its aluminum v-rail counterpart.

Cons: Since the tubing cannot be supported anywhere except at the ends, table lengths of 5 feet or less is recommended because of the possibility of the tube rail itself sagging at longer lengths under the weight of a heavy gantry especially if the recommended tubing thickness used by the builder is less than recommended.

Not offhand but If I can find the time I will see about making this information available over at the ShopDroids forum...

Started work on my plate marker that I started to build a year ago. I did change the design a bit. The plate marker base mount is sandwiched between the Z drive and the X axis carriage with ear mounts that are offset to the right as shown below:



The plate marker assembly will mount to the base ear mount and is height adjustable as required. I'm still waiting on some of the pneumatic components to arrive but for the most part the main unit is finished.





Although I have a pneumatic scribe mounted, I may go with a spring loaded center punch instead as my main interest with this tool is to center punch metal plates for drilling purposes.

Going through the motions testing the code for the plate marker attachment. Test was a success!

You going to add these to your line of products John? Very Nice!!
