The problem has been resolved!

The soft key buttons were faulty. Mainly the one on the far left being the 'back' button. With no highlighted message above the button like the rest of them, it was...

So I've found some forum posts regarding being stuck in different Fanuc menu's. While still being able to switch inputs. It seems to be related to the I/O board. I might have to replace it.

No I've tried the key, chuck closed zero'ed the machine, tried emergency stop. Tried all arrow keys. Everything seems to be working manually.

But I cant get out of the Alarm screen. Which is...

Hello there, I am working on a used Nakamura 3b Slant lathe. The controller is a Fanuc 11t. Equipped with a tape reader.

I`ve looked almost everywhere and spoken to several people

The procedure...

Hello everyone I'm looking for a used cnc lathe able to cut 14" OD pipe, 1" wall thickness. About 2" long.

Any brand any year. Would appreciate some info!

Hey glad to hear more progress is being made on the new software. I am in the process of providing kits to people who want to use the software!

At home bolt on kits. Starting out with the 4th...

Yeah you're right. Totally machine dependant. As long as the points along the toolpath in 3d space match the machine.

And actually Danny I didn't see that option to set a home position. Thanks...

For the trunnion. You will always have to have your part above 0 anyway. Really you should be drawing your chuck / vice ontop of zero as a reference and your part above that. Xyz in the program is...

Yeah oops. I quickly generated that one. It's the file I was testing yesterday. Just remove the first extra fword in the line.

Try this one and let me know what you think.

For me, the feedrate is the biggest issue. I broke an endmill the first time using G94 because as the toolpath changed it ramped up in speed when I did not expect it. Now before every run I sit by...

Ah. That's why.

That's not what I meant. I thought maybe the xyz move as in sqrt( x^2 + y^2 + z^2 ) was dictating the speed of rotary motion. I still think the way it's mixing the motion is messed up.

Maybe g93...

I tried again with different feedrates. I also tried changing the g code to see the effect. It doesn't matter if the c axis is a 52 degree or 5 degree move. The feedrate drops to .02 ish and the...

You can't use trunnion type kinematics for a head head configuration or vice versa. Your control software doesn't care what your machine is. It just converts distances into pulses. But you will need...

I -think- whats happening is the a and c degrees are being viewed as inches per minute in mach.

Yes the rotary move feedrates work. I'm aware the change in z axis height can set the radius for the a axis around zero but is there support for simultaneous changes in C axis rotation?

The travel...

Trunnion Mk3 is on the way

Sooo. Here is 1.07.

I watched the youtube videos with the twitchy movements in the file 02AltParallelSpline posted on the yahoo forums. I checked the gcode line by line and determined there is no...

Yeah and whats nice about the maxscript is it does this for you by calling quat "said axis". Or by using the euler angle equations. Which is how the 5 axis gcode is generated within the script. I was...

I don't think motion control software will have the answer for me. Because the f word in mach or any control software simply interprets the F word as completed time = 1 / the f number.

What I need...

I figured out how to add g93 to the post. But I have no idea how the distance is suppose to be calculated.

A 3d distance move = SQRT ( x2-x1)^2 + (y2-y1)^2 + (z2-z1)^2 )

But...

I've checked out the youtube videos. Seen the couple of erratic movements and think it was a simple typo in the code. Try this one. I also removed the g92 A axis command at the end of the post...

Hey looks good. Thanks for pointing out the bug. I found it. Try this one.

Here is another update. The A axis was acting up.

You can reverse any axis in mach3 settings to match the gcode. Or you can switch the axis orientation with notepad.

Or you can open cnctoolkit with a text editor and set the post up any way that...

There! The C axis is working better now. I'll make a tutorial and post it on youtube once I get some free time.

I also made xyzac the default and set offsets to 0 as default.

Now its up to you...

Well it does. But the C axis needs a bit of work.

I managed to get both axis turning in the simulation. Here is the new file.

So I re-wrote the kinematics control for the xyzac selection to make this easier. Here is the new script file with two example/testing files.

The only request is you post this on the cnctoolkit...

If anyone else is interested in the same setup I have pm me for details. I'm starting a list of interest and may be going ahead with a kit/instructions.
