you only have advanced preview control G08P1
Let me explain how the option codes work. If option code one equals 46 the parameter 9100 would be 01000110 the fist four digits from the left are considered the most significant decimal, and the second four are the least significant decimal. So think of the first four as the tens column, and the second four as the ones. Bit 7 would have a value of 8 bit 6 would be 4 bit 5 would be 2 and bit 4 would be 1. So you have a one in bit 6 which equls 40. And bit 2 and 1 equal one so this is 4+2=6 40+6 =46
This is how you can find if you have a certain parameter option. Next you need to know what the option parameter is for what you want.
Sorry It is illegal for me to continue, as this is the equivalent of stealing software.
If you are interested I can send you a email with a brief summary of what you need to do to repair this problem

Your company could hire my services and I WILL repair your problem. Please I dont want to sound like I am bragging but I have about 20 years experience with fanuc controls even before the 3 series I was interfacing the 7m, and I know woodworking machine problems very well. I wish I had a quarter for every time I repaired a chattering problem.
Travis
Absolutely you need the drives set. This is one of the biggest problems with Shoda, though it is a very good machine, they build the machine and ship it no test cutting.
I dont know how familiar you are with the control but program a 45 degree angle at a feedrate in the metric system (because the machines detect unit is metric)
then check diagnostic 3000 which is following error. X and Y should have the same values.
You can calculate the error using the following formula
fe=fr/60 * 1/gain * 1/detect unit
that is for a straight line, for an angle divide the result by the square root of 2
fe = following error
fr = feedrate
the gain is either 3000 or 4000
the detect unit is probably .001 mm

Mike Olski at GPM should be able to help you

the G08P1 is advance preview control.
There is a parameter called feedrate clamp by radius, you may have to reduce this so that the machine will slow down to cut a more accurate circle.
Also parameters 1852 and 1853 are RV1 and RV2 these have a direct effect of the quality of your cuts. Do you also have chatter marks?
Next cut a circle measure it at 12 and 6 oclock
3 and 9, then on 45 degrees such as 2 and 8 and 10 and 4. Which way is the circle out?
I have repaired these problems on many Shodas over the last 18 years
The M20 is not fanuc, but unique to this particular machine tool builder. I have written logic that if you flip a switch and the machine is not active after a certain time period the control will be turned off.
Please be careful M codes are not written by Fanuc, but by the machine tool builder. I could very easily have M777 be the code to start the spindle instead of the industry standard M03

You never use the letter V in the program at all. There is a G bit I dont remember it off the top of my head that sets simple synchronous control, and another for twin table control. Actually If you use V while these bits are set you will receive an alarm. You must remember to set your work offsets V value to whatever you put in Y put in V.
Also If you DO NOT do the following, when making a G2 or G3 the Y table will move. When ever you execute a table change on the FIRST line that causes motion must have a G17 on it. ie: G0G54G17 X10.Y10.
I have written this ladder logic many times.

If possible max out your 401k, (pre tax dollars)
IRA is a good second choice or look into a variable universal life insurance policy. Dont laugh this is an excellent tax deferred vehicle. If you are trying to save for a childs education and you purchase an education fund, the government see this if you apply for financial aid, but no body will ever see the life policy

you cannot use points in the block drill feature.
Have you created a hd9 file?
you must create this. This file is a representation of your boring unit, you must create it exactly as what is on your machine. In other words if the first 4 drills are 5mm and the second 4 are 8mm, then create the hd9 file the same. The block drill feature looks for a match between your drawing and the hd9 file. So the diameters of your drills must be exactly the same as your holes in the part. Also when you creare the hd9 file make sure your distance between drills is 32mm
let me know if you need help making the hd9 file

at the ptlchg there is a word ptoolcomment
ptlchg #Tool change
pcuttype
toolchng = one
pcom_moveb
#pbld, n, "M01", e
#pbld, n, *sgabsinc, "M05", "Z0", e
ptoolcomment
thanks
George
In my programs, whenever there is a tool change a comment is placed describing the tool. What I would like to do is have all the tools listed at the beginning of the program. Any ideas of what I need to do?
thank you
George
G55 will work from wherever G92 was defined. It is not a good idea or practice to combine the two. G92 is a hangover from older controls, it is not needed on Fanuc controls at all. I never teach it to anyone. Of course you can argue this but after 18 years of teaching customers on multi head machines, I have never had a customer have an accident.

As many people have already said G53 is the machine coordinate system, there must be a G53 on each line, and this must be done in absolute. A command of G90 G53 X20. would send the x axis 20 inches or mm from the machines home. G28 on the other hand works in G91 (incremental)it can work in conjuction with the plc the signal is zpx, zpy, zpz, the plc can use this for many reasons. Some manufacturers use G28 to turn on reference return led's on the operators panel. Where G53 would not typically do this.

First does your machine use the Fanuc PMC?
If it does you cannot punch out the ladder, there are 2 eproms chips in a yellow casette, that you need to read through fapt ladder, then you can print it
