Attached is a file I generated to turn my plasma cutter into a simple hole and slot cutter. If the machine is centered on the center of the hole or slot, it penetrates in the hole-center, moves to the perimeter, and cuts out the hole or slot while compensating for kerf. You still have to determine what that kerf should be, as well as the feedrate.

There are two macros in the file, so Excel will throw up a security message when you open it. You can run it without the macros if you want. The macros are simple cut-and-paste macros that copy the code to your computer's clipboard by clicking on an arrow. I find this easier when wearing gloves. You can also re-record the macros and associate the graphic arrows to them yourself [use Right-click and Associate Macro after you've recorded the cut and paste sequence]. Using the macro is just easier than trying to highlight the resultant code and copy. The basic code generation does not rely upon the macros.

I find it best to copy the result into Notepad or some simple text editor to strip off any formatting. Then copy the results (cntrl+A [select All], cntrl+C [Copy], then cntrl+V [Paste]) to your controller software.

M50 and M51 are associated with turning the plasma cutter on and off. Edit the file based on what code you are using.

The G40 and G41 are used with "D0" which identifies when the tool is being used, but with zero compensation. This makes my controller software depict when the tool turns on and off, but defaults to the radius of the tool I've specified in the controller program, and not the code I just generated with the spreadsheet.

This is pretty simple code, but it easily turns your plasma cutter into a simple drillpress and slot-cutter. I'm considering attaching a webcam to the plasma torch mount so I can center on a mark, then move it over the X,Y to precisely place the torch for a center cut start.

Constructive comments are appreciated!.

I get just over 30mm drilling stroke before it comes apart.

Is there any easy option for a tailstock with more stroke, preferably also with a lever lock instead of the clamp bolt?
I've seen lever conversions of the existing tailstock and the idea is attractive. But I want to make sure I'm not missing any other options. ]]> Benchtop Machines Dougal http://www.cnczone.com/forums/showthread.php?t=111715 Is this possible to replicate by hand? http://www.cnczone.com/forums/showthread.php?t=111714&goto=newpost Thu, 09 Sep 2010 04:47:40 GMT Hey everyone. I'm looking for some advice. I am in the process of building a custom r/c truck. I need to see if it is possible to replicate this kind of countersinking without bringing the piece to a machine shop.


This is a factory piece. It has the motor mount screw head area flat milled out. It has to be that style because the motor mount screw holes are slots to allow for adjustment.

The material I am using is .125 aluminum sheet. Unfortunately I have no clue what grade, (6061, 7075, etc) I got it from a coworker who's full time job is a machinist. Maybe it's neither, it is really shiny. Probably should ask him..lol Either way, is it something I can do on my own? Only thing I can think of that might work would be a router, but I don't have one.

A message dialog box is presented. It presents "Class not registered" with an OK box.

"PartMaster CAD is not installed (or has never been run) on this system.
Please run PartMaster CAD before trying again. You may need to re-install the software."

So a couple of questions form.

Why is some "Class not registered."?

Why the message "PartMaster CAD is not installed..."?

Exactly what is the purpose of File | Import on DCAM?

Hello,
I photographed the process of tapping into the trigger circuit for a Harbor Freight plasma cutter so that I could control it through my CNC router. The goal was to make the trigger non-permanent so that I could remove it from the CNC router and use it by hand. I then connected it to a relay board to isolate it from the controller. It works very well.

I have a EAD LA34AGK-26R stepper motor I picked up from work (they were tossing it as it was an unneeded spare...). It's known specs are:

EAD LA34AGK motor
NEMA 34 class
Hybrid motor
Unipolar
4.7 ohms across the coils
2.35 ohms from center tap to ends of each coil
Operated on 90V power supply previously

I could find a bit of information on the LA34AGK-?? class of motors, but nothing on the -26R motor. They specs are all over the place, so I can't use a "good enough" call. Also, the coil inductance is unknown and do not have the test equipment to measure it. (I really need to pick up a decent LCR meter...)

Obviously, the original stepper drivers did not hold the coils with 90V across them. Does anyone have any idea what the holding current should be on something like this? I would really like to get this thing running doing something as it appears to be a pretty good motor. In it's previous life, it was rotating an arm on a piece of semiconductor processing equipment.
