I am looking at buying a "new to me" mill, another used machine unfortunately but it has a tool changer - luxury.
Both my present mill and the new one use Fanuc O-MD controllers but the new mill has...

Tried 9200 baud today. Worked fine but no perceptible improvement in cutting speed.
A thought did occur to me, if you feed a higher data rate into a small buffer you are likely to get more XON/XOFF...

Thanks for the replies.
After some delays my system is working again. NOTE If you change to a DNC computer with an ASUS motherboard that includes a remote serial port be careful. The board...

This is a sort of generic question but since I am running an OMD based machine it could be a good place to discuss this.

I recently adopted DNC operation. The machining operation is smooth but I...

Sorry Dcouper, my bad, I should have said "Alarm 008". Thanks for the correction.

In retrospect the program was fine, it was the Parameter38 setting that was wrong. I can only think that since I...

Thanks to anyone who considered my problem! Playing provided the answer but I will explain in case my solution helps any body else.

I got my machine used and the basic download from PC to memory...

Sorry to bother you folks - I can usually work these things out but I am stuck now. Would appreciate some help - I am sure someone has seen this problem before.

For the first time I am trying to...

Great information

So, to use a simple example, I have one of the electrical contact set-up sensors with a 0.2 inch diameter probe. Therefore, whenever I use this probe I have to adjust the zero...

The subject is becoming a little more clear now but I can see that I have a lot of thinking to do.

HuFlung,

This is a Kent box-way mill with Fanuc O-MD controls. I have the Fanuc yellow manuals plus a very sparse (photocopied) machine manual.

On start-up I manually drive the table to the...

Thanks gents,
Beege,
G52 is not included as one of my Gcode options which is why I was wondering how, and if, I could use the "shift" settings. The extended workpiece offsets are turned on in my...

Please help me to continue learning how to most efficiently use my mill.

I am quite pleased with some of the individual items I've made so far and now I am getting into fixtures and multiple...

Please add incremental cuts to the "go-around" toolpath in the X/Y plane similar to the option for the Z axis.

I had the notorious CopyMinder crash on my system that eventually lead to the use of a dongle. The folks at Dolphin were pretty helpful, especially Michael in UK.

My experience confirmed the...

I like many of the previous comments but the first thing you need to do is get rid of Copyminder.

It's been quiet here so let's ask a question for the experts.

Let's take the example of thread milling. Whether or not the g-code is created as a helical move or a series of straight moves depends...

I post this in case anyone else runs into this alarm message. There is very little help I could find anywhere about what was causing the problem. I am a newbie so this was confusing to me but the old...

Dcoupar,

Not yet. I am still working with basic arcs.

Got to teach myself g-code basics, Dolphin, machine use, fix all the problems - Oh, by the way I need it done by next Friday cos' Dcoupar...

Thanks Al,

Dcoupars example showed the way to do this so I think I am OK.

I tried to find a good book on CNC programming recently. I even went to the famous Powell's Books in Portland which is...

Here is a sample of the code:

N2345G01X0.279
N2355X0.2788Y0.0099Z-0.4135
N2365X0.2784Y0.0198Z-0.4132
N2375X0.2776Y0.0296Z-0.4128
N2385X0.2765Y0.0394Z-0.4124...

Gncc50,

As I have mentioned I am new at CNC and, at the time, I did not know that my mill had the helical option so he wrote code with Dolphin that simulated helical operation in software. This...

Gncc50
That is exactly what happened but my example made even more code. The support person from Dolphin, really nice and really helpful, thought that I would have to use software helical generation...

Hi Guys,
Had a good day on Saturday. I got the parameters backed up and I converted Dcoupars program to run on my machine and cut air, now I have to modify the program for my single-point threading...

Thanks Al,
I am heading out to my shop to do the backup right now before I play with Dcoupar's program.

Thanks Dcoupar,

I am going to print out your example with each line quadruple spaced and work through it.

I have a smaller diameter single-point carbide thread cutter since I haven't decided...

Thanks Al,

I just got the RS232 working recently so I have not backed everything up yet. I realize that that is the first thing I should have done but I have to read up on how to do this.

I...

Well Dcoupar,

I ran your little piece of code and there was no warning and the position display showed a very satisfactory 3 axis movement. I guess I have helical after all - now I need to learn...

I am not trying to dodge Fanuc's control. I was just wandering what options there may available be that I did not know about. Not making this information easily available is a bit like having a...

dcoupar

I'm new at this but my original need was to reduce the amount of code generated by my CAM program for threadmilling. Someone was kind enough to write a sample threadmill example for me and...

Al, hope you see this:)

I am lucky in that I have a complete set of manuals with my machine. The Fanuc "Operations" and "Maintenance" manuals plus the "Manufacturers" manual.

I checked my...
