We have the formulas to get output from a fresnel integral....we can even get that data on a spread sheet.

How to write a program to take the data..better yet the formula inputs and turn it into...

We have several formulas that can get us the formula output for fresnels, how do I get the G-code?

I have seen the diamond turners take excel file outputs and make g-code from that(I was watching...

I am in a similar situation to underthetire, there is an LB12 OSP500l-g sitting in the shop next to me that nobody knows how to use.

I can put programs on from mastercam
No leaks
Powers up fine...

I agree....it is strange. Now we will start looking to speed it up. But at least it works

Okay,

we can get programs from our PC to the OSP500l-G no problem now.

we will use visual lathe to program (right now I am writing the code in notepad) so we can avoid using the OSP to...

We got it!! thanks for all your help

We had our OSP500L-G AT 2400, 4800 and got nothing, now with Baud rate at 600(max allowed in the Okuma manual) we can send programs all day long....it really doesn't take that long...

Maybe it was...

We want to use servos, specifically two axis

Is anybody using granite with EMC2?...

I have all the mechanical hardware for a good build and have hesitated buying controller hardware....

I have a 4 axis CNC running off of MACH3, set up and...

I have been looking to put an ethercat system together....my price in quoted from beckhoff(guys who make twincat) was 5400 for three axis drives and software...not expensive(but not cheap)

I haven't done serial communications since the 1990s, can you elaborate a little?

We are using the correct file extension, .min

Are you talking about what is actually in the NC file itself?
...

Ncnet says it is transmitting but we get no verification on the okuma....when we punch "Read" on the Okuma we get the message "RS232 not ready"

Any help would be appreciated

com channel: serial...

We have an old Okuma lathe and all the manuals. We would like some help establishing a connection to the lathe using hyperterminal (or if anybody has an idea of shareware).

Thanks

okay:

"Next You enter R (read= file transfer from RS232 port to OSP) either PU (punch= file transfer from OSP to RS232 port). There are also soft keys for that.
Hope, I understand Your request...

most interesting is what kind of CNC software You have developed for the Okuma control? It's a different matter if You mean to upload part program file to OSP. It is under Edit mode, PIP function...

Okay,

Problem1:

I got a PC up to the machine and fired up the controller when the RS232 cable was plugged into both(PC and CNC) the controller cuts out.

Problem2:

We have the manuals for...

I need to communicate with the CNC.

Will I need a PC with LPT port sitting next to the machine?
Is there specific software to load on the PC?
Can I choose a file location at the Okuma...

How do we get a Mastercam/Visual lathe. program on an old Okuma LB12?

we can get the post, and there is a LPT port/RS232....but that is all I know.

PCW Mesa, Hobby dad...

Looks like we are on parallel tracks here....however my question is what would be the optimal analog(brand) amplifiers to go with Mesa hardware?power at the screw looks like...

Well I bit the bullet and took one bearing apart allready....it was easy except chasing the tiny things around the bench...

I bought used rails and cleaning and greasing them didn't work so I...

Okay Al,
I'm gonna bite.

Here is the goal: Make a performance CNC system, using EMC2 and comercially/commonly available hardware.

Performance defined as:

rapid rates of 1000mm/min or more...

Al,

You are good to go

Here is another opinion on the subject:

While EMC CAN do this, it is definitely uncharted waters. I think I see what they are doing now, it only takes 2 drive...

yes,

i am further down the rabbit hole...

I know what PID is....I can actually calculate Derivatives, Integrals and postion functions. It is calculus and the copmputer does it a gazillion...

Al,

Yes we are going to use dual feedback. The machine requires very tight tolerances(optics).

We are honing dovetails now for cross slides.

I looked at Galil...how ever they sugested a...

Samco

So maybe that is my fundamental misunderstanding: EMC2 closes the loop...is that the same as comutating the drive?

I understand the concept....my machine is open and we have traced all...

We are trying to use Pico system, right now and John has been very patient and informative.

We are starting with the controller Pico(PPMC2) and EMC2.

Positioning is gonna be with a renishaw...

Al,

I am talking Analog Amplifiers from AMC and Copely

I was on the phone with the tech at Advanced motion controls today. This was reference a build we are doing.

I am no EE, I am a...

Anyone familiar with the process of replacing the ball bearings on INA linear rails? similar to THK or HIWN

I have some used INA linear bearing KWSE 25....the block kind, that ride on a profiled rail.

Anybody familiar with replacing the ball bearings inside?

So the saga continues

We are trying to get sinusoidal commutaion for some motors, I prefer AC brushless.

When I talk to AMC and Copely they state the only way to get sinusoidal commutation is...
