Relearning set up on my lathe. CNC11 V3.14 I want set up new part F1-F1 Z axis , X axis. Pelims:all tool offsets 0.0, all tool wear set 0.0. My process to simplify my understanding of what is happening. I set up the part first. I start with a Z several inches out from actual part for test run. That works every time.F1-F1- Z0.0 tool 01. DRO Z goes to 0.0 WCS#1. Now I skim cut my part, F8 Set X, I input the measured diameter, tool number, then F10 to save. Still OK.Now I go to F2 tool Offsets. I have no idea where the phantom reference tool 00 is so I use T0101 and tab over to the X off set column, F1 brings up establish X diameter dialog and I input the measured size from part set up which also is still showing on the screen I now press F2, then F5,then F10 to measure and save, repeat for T02 threading tool. Tool 1 shows zero offset as it should nothing was moved from the skim cut, T02 shows -0.071" it is slightly shorter. So far so good, I understand the offsets, I understand that the DRO shows the actual tool position related to the part and the true distance the tool tip is away from X0.0 of the lathe for T0101. I run F4 run execute my program and everything looks good. Now I reset the Part Z on the actual part, just to be sure I retouch the X maybe I bumped the handle and it moved 0.005, I retouch, move away and measure, Now the part we have been waiting for. When I input the retouched measurement and hit F10 the correct measurement still shows in the part position box but the DRO X changes to a different number. Now I cannot get the machine to acknowledge the correct X tool tip location. I can do this same process on my offline CNC11 and it works correctly. I videoed the process to see what I might have done to corrupt the X position. WCS#1has not had any x change throughout this process only Z change when I moved over to the part. It is like there is a random number generator creating the part X diameter. the change is usually in the range of 0.050"-.090". In the attached photos carefully look at the line numbers. It checked the machine position at each G28 execution. At the program start and at the first tool change G28 goes to machine X0.0,Z15.0. At the end of the threading cycle it goes to X0.0375 and Z15.0 or something in that range but not the same each time. Z is correct X is wrong. I have to shut the machine down completely and disconnect it from the power source, then upon powering up, restarting controller loading file and setting up part and tools it will again run one time then it picks up the phantom X off set after the threading cycle and goes to the "new" G28 position. In the photos you will see a picture of the Part set up screen showing 3.0 ini X part position box but 2.9262 in the X DRO above. When you press F10 to save the input number it briefly flashes on the DRO then it reverts to the 2.9262. This number is often the T0202 offset amount but not always. I edited the T0200 from the last G28 line and that did not make any difference. The Centroid manual does not recognize T numbers as valid points go to, there may be some secret code that recognizes tool offsets and goes there instead, but i couldn't find it in the V3.14 Manual.
Mystery #2. When I execute my program the threading cycle cuts about 0.07" smaller diameter than the minor diameter programed for the part G76X2.11 Z-1.0 R0.0017 P0.07 Q0.01 F0.125. The g-code shows X2.11 and it cuts down to X2.04. Now that corresponds to the P parameter of thread ht. But 2.11 is minor diameter. P should be subtracted from X2.25 the Major diameter programmed in the intercom line on the detail screen. It would be nice if it just went to the programmed coordinate and I could use tool wear to adjust fit it up. may have edited this line and put 2.18 in as the minor diameter to get it to cut to 2.11 on the attached program file.
Last item. T0000 confuses me. Where is it? It shows up on the figures oin the manual and is discussed in the setting u of tools but appears to be an obsolete legacy process eliminated by using T0101 instead. Andwhy does intercontinental post process the G28 moves with the tool number and this phantom offset?
I am going to send this off as is as I have lost it 3 times with computer glitches and am tired of recreating it. I hope it makes some sense
Now I know what "Place inline" means. It means insert in the body of the message at the cursor location I bet.
Appreciate any help
