Hi, I loaded today 2021 beta version of Mastercam in order to check ADVANCE DRYLLING CYCLE. After installing it it is extremely slow i have to wait couple of minutes to do anything. (Advance Drilling Cycle looking good it is what I need) I have: OS Name Microsoft Windows 10 Home Version 10.0.17763 Build 17763 Other OS Description Not Available OS Manufacturer Microsoft Corporation System Name BASE System Manufacturer Acer System Model Aspire TC-885 System Type x64-based PC System SKU 0000000000000000 Processor Intel(R) Core(TM) i5-8400 CPU @ 2.80GHz, 2808 Mhz, 6 Core(s), 6 Logical Processor(s) BIOS Version/Date Acer R01-A0, 29/03/2018 SMBIOS Version 3.1 Embedded Controller Version 170.170 BIOS Mode UEFI BaseBoard Manufacturer Acer BaseBoard Product Aspire TC-885 BaseBoard Version V:1.1 Platform Role Desktop Secure Boot State On PCR7 Configuration Elevation Required to View Windows Directory C:\WINDOWS System Directory C:\WINDOWS\system32 Boot Device \Device\HarddiskVolume1 Locale United States Hardware Abstraction Layer Version = "10.0.17763.1007" User Name BASE\wojte Time Zone Eastern Daylight Time Installed Physical Memory (RAM) 16.0 GB Total Physical Memory 15.9 GB Available Physical Memory 10.3 GB Total Virtual Memory 18.3 GB Available Virtual Memory 10.3 GB Page File Space 2.38 GB How can improve performance?

Can I get this public version of Mastercam 2021 to test my holes please? I have licensed version of Mastercam 2019 and 2020 no load to computer yet.

Thank you very much. That all I need. Very informative and easy to follow. You guys make my day.

Yes I did. But there is the the only "Point cycle" and there is only point location and nothing about depth parameters and other parameters. Consequently when I posting it is not giving me all parameters which you give me as example. So if you kindly can show me how you did entire post I would appreciated. Thank again

Thank you very much. That is what I need. The only problem is how can I do it for all holes by programming it entirely in Mastercam and get the post for my Haas machine rather then copy and paste each hole using your test code.

Thank you very much I was able to open file and see exactly what you mean. I do not see however in backplot rapid movement. Maybe this will be in the post.

Sorry but what is IIRC and how I can "stacked 2 drill cycles on top one another" . Can you please explain that.

Thank you very much for long explanation. I will test it today evening. Thanks again for help.

Because of my little experience with Mastercam i do not quite understand your explanation. Can you please tell me more details. Thank you.

Thank you. I have 2019 version of Mastercam. Can you please load file in 2019 version. Thank you. Wojtek

It is possible to program in Mastercam through holes in square tube 4X4 x0.375 . I would like to keep drill in the same hole drilling first wall then rapid down to bottom wall and drilling bottom wall, and then go to next hole. I don't like drilling top surface and then come back and lower "top stock" and drill bottom wall. I would rather stay in the hole. I can manually modify post ,but I have 30 holes and editing each one is very painful. Thank you.

Hi, I am trying to use FBD and have many problems with it. For this example two 0.375 hole supposed be reaming holes, but Mastercam not drilling them for it, neither ream them. Insted using 0.375 end mill and I can't change it. Please help me resolved this issue. 3-480-034-014NEW.mcam

Hi , I try to use FBD but instead speeding process it slow me down. It is giving different order of drilling and taping process. First drilling then , spot drilling then taping i have change order after. It is not picking right drill for tap hole. Plus showing so many FBM drilling cycles in tool path. See screen shot. Anybody can comments or help setting it correctly. Thank you.

Thank you. That was very.

Hi, I lost option to put line number in my post. On tool setting page I have sequence number box "START" with 10 and next box " INCREMENT" box 10 as well but post not putting line numbers. How can I get thous numbers back. Thank you.

Thank you.

How can i change for 90 degree ? I do not see this option.

Thank you. I am talking about first operation (round corners).

Hi, I am working on the project below. I did programming ,but i am not happy with the finish on round edges. How can I get better finish then this without putting much more time in operations. I am using "Surface flow line" with 3/8 ball nose cutter. Any help appreciated. 3-400-004-006.mcam

Should I create new geometry or use tool off set?

I will try this. What type of tools to use?

Sorry but I do not understand your question. Can you please explain what this mean in simple language.

Hi, I am trying to machining attach part. I have problem with cleaning those steps in the grooves. How can I do it with minimal extra time for operation. What would be the best approach for deburing those bosses . Any help and commends appreciated. 3-340-036-008-B.mcam
