Dare I ask; no Mastercam Wire?

Last one. This is a spectacular machine. It is only a 35% discount. Not quite the 40% they usually give, but that is likely due to the quality of the components in this build. 256 GB of RAM (@ 2933 MHz DDR4, and it is even the ECC, not that 'non-ECC' cheap stuff...)

So... Does this mean no more Lowe's?

How about cutting your calculation times by 40-70%, instead of 10-15%? How would that be possible? By applying the correct technology.

I'd be very curious to see how that AMD Ryzen Threadripper chip performs "in the real world". My hunch is that Intel will eat the AMD's lunch, for Mastercam Performance. While having "128 Mb" of Cache sounds huge, that is the L3 or "spillover" Cache. L1 and L2 Cache are the primary and secondary blocks of CPU memory. The reality is that this particular AMD chip is optimized for programs that run many simultaneous multi-threaded applications. I don't believe that Mastercam makes use of Multi-Threading in the same way that other programs are designed to make use of the Multi-threading. What do I mean by that? Well, a Stock Model for example, might be setup to process as a "separate thread". But, I don't believe that the Stock Model Calculations themselves, are multi-threaded. In other words, the Stock Model is still calculated by a single process thread, once it is allowed to start calculating (could be dependent on other "input", like a previous toolpath). The 'Stock Model Thread' is not hyper-threaded, so it isn't like that Stock Model Calculation is being spread across your 24 Cores/48 Threads. Technically, you could generate up to 48 individual Toolpaths at at time, but you are still limited by several factors: There is a 'databus' between the Hard Drive (SATA or SSD), and the Chip (processor), which is basically 50 times slower at data transfer, versus the clock cycle of the chip. The main "throttle" in processing data is not the size/speed of the chip. It is the size/speed (flow rate) of the 'pipes' that handle the Data I/O between RAM, CPU, and Storage Memory. AMD has historically had much more latency in data transfer between L1/L2/L3 Cache, versus Intel.

The other thing you get with a Dell Factory Outlet Computer, is the 3 year hardware support and warranty. I have only ever had one component fail on a Dell. I had a hard drive that went bad, about a year into owning my first Precision Workstation. After remotely diagnosing the bad hard drive, the technician on the phone said "Yep, that result confirms the hard drive has failed. You will have one on your doorstep by 10:00 AM tomorrow". I was not happy to have to restore my files from my last backup (lost about a week of work, and learned to make backing up my data a priority!), but I was super happy with the support and service that I received from Dell.

While I know that it can be cheaper to build your own system, I much prefer to just buy what I need from the Dell Factory Outlet. I don't need the absolute 'latest and greatest', and I find that I can get the cost down to "almost the cost of the components alone", by just buying a 'refurbished' system from the Outlet. What is your budget for this computer build? I did a quick search on the Factory Outlet, and came up with some amazing systems, at reasonable prices: Example 1: Precision T5820 Original Price: <$5,002.00> Outlet Price: $3,001.00 8 in stock Certified Refurbished Windows 64 Bit US English Qwerty Dell KB212-B QuietKey USB Black Keyboard Optical 2-Button Mouse Tower Core X 950W Chassis CPU Thermal Heatsink Original Price$5,002.00 Total Savings$2,001.00 Standard ShippingFREE Outlet Price$3,001.00 PR T5820 : 3 Years Hardware Warranty with Onsite/In-Home Service after Remote Diagnosis Tech Specs Intel Core X Series i7-9800X Processor (8 Core, up to 4.40Ghz, 16.50MB Cache, 165W) Windows 10 Pro 512GB 2.5inch SATA Class 20 Solid State Drive 128GB (8x16GB) 2666MHz DDR4 UDIMM Non-ECC NVIDIA Quadro P4000 8GB GDDR5, 4 DP Dell Outlet Precision T5820 Example 2: Precision T5820 Original Price: <$4,641.00> Outlet Price: $2,785.00 1 in stock Certified Refurbished Windows 64 Bit Dell KB216 Wired Black Keyboard Optical 2-Button Mouse 950W PCIe FlexBay RTX Tower Chassis CPU Thermal Heatsink M.2 Carrier Original Price$4,641.00 Total Savings$1,856.00 Standard ShippingFREE Outlet Price$2,785.00 Tech Specs Intel Xeon W-2145 Processor (8 Core, 3.70GHz, 11MB Cache, 140W) Windows 10 Pro for Workstations (4 Cores Plus) 1TB PCIe M.2 NVMe Class 40 Solid State Drive 64GB (4x16GB) 2666MHz DDR4 RDIMM ECC memory Nvidia Quadro RTX4000, 8GB, 3DP, VirtualLink Dell Outlet Precision T5820 Example 3: Precision T5820 Original Price: <$3,300.00> Outlet Price: $1,980.00 1 in stock Certified Refurbished Windows 64 Bit US English Qwerty Dell KB212-B QuietKey USB Black Keyboard Optical 2-Button Mouse Tower 950W RTX Chassis CPU Thermal Heatsink Original Price$3,300.00 Total Savings$1,320.00 Standard ShippingFREE Outlet Price$1,980.00 PR T5820 : 3 Years Hardware Warranty with Onsite/In-Home Service after Remote Diagnosis Tech Specs Intel Xeon W-2102 Processor (4 Core, 2.90GHz, 8.25MB Cache, 120W) Windows 10 Pro for Workstations (up to 4 Cores) 1TB 2.5 inch SATA Hard Drive (7200RPM) 64GB (4x16GB) 2666MHz DDR4 RDIMM ECC memory 8X Ultra Slim DVD ROM Drive Nvidia Quadro RTX4000, 8GB, 3DP, VirtualLink Dell Outlet Precision T5820

Hide also has the (optional) "Hide more entities" command, and "Unhide some" commands. These are great for "hiding more stuff", or "unhiding something that was previously hidden". I like to map these to F11 and F12 keys, and put them on my custom Right-Click menu. The "reverse" selection command is technically: Invert Selection (button) on the General Selection Ribbon.

I use the point of the insert, like Roger showed. I touch off the face, set the offset to the face, then make an incremental adjustment to the offset, so that the center "tip" of the V is the driven point of the tool in the part program. This allows me to get thread length, chamfer, and pull-back settings correct.

What particular machine is this for? TLO stands for Tool Length Offset. In general, with a Fanuc-Style Machine, the following G-Codes are used to control positioning: G00, G01, G02, G03 - Motion (Rapid, Linear, CW Arc, CCW Arc) G17, G19, G18 - Planes (XY, ZX, YZ) G40 / G41 / G43 - Cutter Compensation (XY Contouring Control) Programmed with a "D Value", which corresponds to the "Diameter Offset" being read for the XY adjustment.) G43 / G44 / G49 - Tool Length (-,+, cancel) (Reads the "H value" to correspond to the "Height Offset" being applied to the active tool. Typically T22 = H22 = D22) G54-G59 - Work Offset (XYZ location of Program Zero Point, values are typically given "in Machine Coordinates", from the Machine Home Position.) G70-G89 - Canned Cycles (depending on Machine Configuration). Macros to automate repeated motion types (Drilling, Pecking, Tapping, Boring, Reaming, etc.) G90 / G91 - Absolute and Incremental Motion codes G93 / G94 / G95 - Feed Mode (Inverse Time, Units per Minute, Units per Revolution) G98 / G99 - Controls how tools retract after a Canned Cycle Call. Using Cutter Comp (G41/G42/G40), and TLO (G43/G49), along with Work Offsets (G54, G55, Etc.), allow us to "position a block of stock or work piece anywhere on the machine table", and then we can "tell the machine where the part is located", using a Work Offset. The Cutter Compensation (G41/G42 with a Dxx value), allow us to adjust the "XY size" of the part. We can use different "D Values" (offsets) to control different part features, allowing us to fine-tune the cutting process. TLO allows us to adjust different "depths" on the part, by making slight adjustments to different "height offsets". This allows us to compensate different "part features", by using a unique "TLO" for each feature (potentially), or adjusting "all features" that a tool cuts, by changing a single Height Offset value.

Yes, this is likely a Post issue. Typically the Post is setup to retract to Toolchange height, change the tool, then move to the XY start point (in rapid), the approach the Clearance or Retract Plane height, while enabling TLO (G43 Hxx Zzz). So the approach from Toolchange to start point should be in Rapid, unless you have "convert rapid to max feed" enabled.

.125 (1/8) .187 3.125 (25x) 3 1/8 4 959108 68.90 959108-C3 73.70 Harvey Tool. They have these in stock. No need to get anything necked down. This is 25:1 D2D Ratio. They also stock a 30:1 (3.75 Reach!). For $70 bucks each, I'd buy like 4 of them. That way you have a couple backups, just in case, plus you have a few arrows in your quiver for when you get another crazy request...

Yes, that is true for Fanuc style syntactic in general. I think you should be using G54.4. WSEC allows Tilted Work Planes (TWP/G68.2), Dynamic Work Offset (DWO/G54.2) does not allow TWP.

Did you remember to "force a regeneration" before each Posting when doing your tests? When you change MI or MR values, it does not mark the Operation as Dirty, so the values actually don't get written to the NCI file. I'd confirm that first, before we do additional testing. Making Post Changes, it is easy to see the output change. Making MI/MR changes, it can be deceiving, if you aren't aware that you must force the Ops to Regenerate to see the output change...
