Exactly! When you combine fixture offsets and tool length offsets on the same line the machine does the math right everytime. The way I have my students do it is:
1) set tool length(s)
2) MDI G0G90...

If you set all the tool lengths to the table then the Z value in the fixture offset needs to be the distance from the table top to the Z zero surface. We use a tool length probe on our Fadal. The...

Whoops! Just re-read the original post. He will have a crash on line 5 and line 12. Line 5will hit the limit because of his z offset value. Line 12 will hit it again because the fixture offset is...

You just need to combine your xyz into one line.
G0G90X1.Y0E1Z3.H1
The z value in your fixture offset exceeds the plus value above the z cold start limit. Even though you didn’t command the z axis...

Never broke a pull stud. Never. Now, about those Belleville washers on the draw bar. That's a different story.

Try shutting off z and fixture offsets all on the same line.
This works for me:
G0 Z2.0 M5 M9 (just above clamps and part)
X0 Y0 Z0 E0 H0 (turns off fixture and tool length offsets)
M2
I don't...

Thanks mkd for the reply. I can find no clearance plane field in the lathe rough cycle. I redescribed the stock so it showed material on the outside and now it works just fine. I think as long as I...

When using a roughing cycle in a bore as the last operation Mastercam sends the tool home without retracting out of the bore. (OUCH!) Am I missing something simple?

Thanks,
Jim

We have the TS27R probe for tool touch off and it works fine even in our not so friendly to the machine enviorment (a college). I use a "home made" macro to pick up the tools as the cycle that came...

If the z value is greater than 4.0 inches in the fixture offset, then you will need to combine the fixture offset and the tool length offset on the first motion line. I use a tool probe to establish...

I modified my post to always put out a G9 after each tool change. That cured the slows but beware that you might compromise the integrity of the geometry of your part. It may tend to round off...

I set all the tools to a common reference. We use a tool length probe but a gage block on the table top or top of the immovable jaw would be fine. Next I measure the height difference from the common...

I have used all three but only MasterCam and Esprit for WEDM. Esprit is my top choice. MasterCam isn't bad. Pro-M is painful for me. If Pro-M is all we had to use then I would make it work. Do you...

Hello All,
I want to insert a M01 about .050 away from the end of a wire EDM tool path. When I highlight a chain and right click some of the functions are greyed out such as "change at point"
Why?...

Both are correct. The first example is format 2, and the second example is format 1. The first example will run in format 1 or 2, but I'm not so sure about example 2 runinnig in format 2.
Whew! That...

Just out of curiosity- are you running format 1 with a G8? I also do alot of surfacing. The machine defaults to G9 and if G8 isn't coded the difference is dramatic.
Hope this helps.

One simple thing worth noting- The difference between an "A" and an "A-" command when in absolute positioning is only rotation direction. I'm not totally sure that is spelled out in the manual....

I bypassed ours when the machine was only about a year old. Accuracy loss is zip. My Machinery Handbook lists the linear expansion per unit length per degree F. for steel as .00000633 at 68 deg. F. ...

SETTO

I believe that sets the current position to #1

Hope this works,
Jim

Look at parameters - Misc values - in your operation menu. The first box should allow for a 0,1, or 2 option. Change it to 2.
Hope this works.

We have had good luck holding taps in nothing more than ER collets. As far as tap styles- name brand spiral pointed taps for through holes and spiral fluted taps for blind holes in stringy material....

I think I would be suspicious of the cold start location. The machine shouldn't need more than Z+ 4. for a tool change. Is it possible that the Z zero was set above the Z cold start position?
Techman

The Z move could be made incremental within a sub program.
Something like this-

L0100
G91G1Z-2
G90
Y50
X50
Y0
X0

I have a tool length macro that I use. I never liked the "built in" macro in the utility portion of the machine because it forced me to enter a full dia comp into the machine and I only use "wear...

I modified the post to always out put that line at the end of the program. It took a bit of tinkering on the post but it is worth it. As it stands now I post code from MasterCam, load the program in...

I run our machine in format 1 and use MasterCam.
It would post-

G84.1 Z-1.2 R0.1 F320. Q.0625 M45

If I want the machine to tap in high range you would use F320.2
That would force the machine...

You should be able to do all. It has been a while but I wrote macro programs for some tabulated drawings where the operator had to plug in data from the drawing.
I run our machine in format 1.
It...

As long as you are programming in G90 mode:

R0 is an absolute value. It has to be greater than "Z"
Z is an absolute value. It has to be smaller or deeper than "R0"

If "Z" zero is the top of...

If there is a Z component in the fixture offset that could cause the machine to over traval in the Z axis. On our Fadal we use a tool length probe that is below the Z zero plane of most set ups. If...
