That is where we are- new machine with unfamiliar options. We have a good squad here James and the forum is so helpful-- so with negative capability we keep moving.

Thank you James and Millman for the prompt answers. We are working on all this- and every bit of discussion and information helps! I copied the macro settings that you dropped me James, and the G10

to cncappsJames because of an older thread he was on: I have been reading an older thread from 2022 about setting workpiece error, so I am coming into this conversation because we have a new 5 axis horizontal trunnion machine here and we are all new to G54.4 and TCP G43.4 programming. I am working with the operator on the machine to figure out where we put in our fixture offsets and any workpiece location errors or differences-- and that is covered above. Its funny but the Fanuc America videos on the subject are very clear about G54, G54.4 and finally G68.2 EXCEPT where to store fixture offsets and workpiece location errors. All of the work in the videos is done by probing with values loaded automatically. We are currently working on all of this based on the excellent thread above and the screenshots of the machine control. We have done lots of vertical 5 axis programming using G54.2P1 so we are moving up to the G54.4 etc. My question is why is G68.2 in the code at this point? We have a brand new post from Postablility and so we have a few kinks to work out- but isn't G68.2 a specialized local work plane for only certain tilted work plane scenarios? Is it okay to turn it on right away, because our new post turns on G68.2 right away. In the Fanuc America videos G68.2 is on a .pdf but not really covered as much as G54.4 and G05.1Q1 nano smoothing.

Ol' Godzilla is a big machine alright. Thank you for the sample code- I will keep it handy as we get deeper into G54.4 and G68.2 etc.

MIL-TFP-41, Not a bad idea. I can send the sales guy a message and he can forward to Kuraki USA in Chicago. Thanks.

The option was purchased a year or so after being installed. I am surprised Fanuc didn't mention this servo tuning when we called them in to turn on the option. I have run and programmed Kuraki machines since 1996, and they are a great MTB. The Kuraki service is excellent- Japan via Chicago. You are correct about testing features before signing off on the installation- all machine options should be verified. The newer G54.4, G68.1 and G43.4 should be proved out if that is the route you are taking. We are in the process of changing over our Mastercam post to run certain new machines this way.

Newbeee, Thanks for responding to my post. The parameter settings aren't servo related, they are max and min distance and rotation axis settings for using G05.1q2 smoothing. But either way I don't like to change settings unless I am sure I am doing the right thing. I agree that we should let Fanuc make their adustments to the machine settings. Jswistak

Aaron, That machine gets everything that is too big for the other horizontals. What is cool is we have a 5' diameter Tsudakoma rotary 5th Axis to go with it. Also, besides the G05.1 Q2 we are working to get G68.2 and TCP set up.

We are running a large horizontal CNC with a Fanuc 31i B5 control. We purchased the AI Look Ahead (G05.1Q1/G05.1Q2 ) option but all parameters related to the option are still at zeroes. For this control the parameter numbers are #8486-9492 and #19581-19591. Most of the values are maximum distance, minimum distance, max angle, min angle etc. We were also told we should have Fanuc come in and do a servo-tuning for this option. Not sure how long it will take to get Fanuc in the building but some starting point parameter settings would be a great help. The machine is set to run in inches, not metric. I have programmed a swarf cut in Mastercam and this causes x, y, z to move as well as the table B. I turn on the AI look ahead with a G05.1Q2X0Y0Z0 command just after the G43 tool length. We are using G54.2P1 dynamic fixture offset. The AI2 flashes on the screen during the tool path operation. We found that the roughing passes look better than the finish passes so we run with the tolerance up higher for less code. This is a large machine so we are pivoting about 50" from the center of the table for this cut.

My time for Benchmark 3_0 was right at 5 minutes. I'm trying out a new machine with a 3.7 Ghz Xeon with 32 Gb ram. I had 4 threads turned on for multi-threading and switched to 8 but the time got slower by a minute. I went back to 4 threads and the time repeated. Fastest machine in the programming room so now I have no excuses.

The Nvidia card can be customized for different cad cam programs such as Mastercam and Autodesk or Siemens software. Right click on your desktop and select NVidia Control Panel. Add Mastercam2017 to the list of programs to customize and change the following settings: CUDA-GPU's -select 'use these GPU's - Quadro K4000 -check it. It will show bold 'all'. The next setting is OpenGL rendering GPU- again select Quadro K4000 and it will stay bold. The last setting is Power Management Mode- Prefer Maximum Performance. I also right click the desktop and modify the nView Desktop Manager by selecting Profile Manager and load 'cad' and select it. These settings were from an earlier Mastercam forum post from a few years ago. We upgrade our Mastercam to 2017 but don't go back and reset our video cards to the new software. Please give these settings to your IT guys or modify at your workstation and it should help your machine's graphic performance. Not sure why NVidia hasn't included Mastercam for preset values like they have for other major softwares.

I was able to stop the windows from jumping to the single monitor by using the NVidia NView Desktop Manager- under Profile Manager- by setting the current profile to 'cad'. The other choices were 'advanced' 'dcc' 'default' and 'finance'. The window for the Op Manager was sometimes transparent but there is a toggle for that too in the NView Desktop Manager. You can specify certain applications in there too just like in the NVidia Control Panel. There are settings in the NVidia Control panel that help Mastercam and verify work much better. Those settings are in another post online here. Thanks to gcode and GregJ for responding to my question.

Our IT company just updated the drivers for my NVIDIA Quadro and now whenever I need to do any chaining, everything goes to one screen on my dual screen display. Has anyone experienced this- and had to fix it? It sure is annoying. Thanks, JSwistak Westfield MA
