"One Perfect Part at a Time"

CNC Control Penchant (and a new pendant)

The switch to Linux CNC was not without some trepidation. I left a machine control system (MACH3) that has worked well for me for over a decade. When something old still does its job very well there is no need to make a change. (It’s a shame human corporate careers don’t follow that philosophy. 🙂

The truth is , MACH3 is still a perfectly fine CNC machine control program. It’s a tool that just keeps working. The problem I have been bemoaning is the computer operating system with which it must operate within, has left it in the dust and… Continue reading

LinuxCNC – Tool Change (part 2)

LinuxCNCYowza! More to the tool change than I realized in LinuxCNC. The tool change routine exists in the latest available stock version of LinuxCNC but it is poorly implemented for a manual tool change on a hobbyist machine and unworkable as is, for an automatic tool changer.

The good part is that the bones are there. It is up to the user to hang some flesh on those bones.

LinuxCNC will respond to the tool change code installed in the Post Processor I mentioned in a previous post, by stopping for a tool change. But that is all it does.… Continue reading

LinuxCNC and Vectric Aspire

For a moment, I thought I may have made a small miscalculation in switching my HB2 CNC router to LinuxCNC.

I finished creating a detailed sign carving in Aspire using three different cutting tools to make the carvings. I have been using MACH3 for my controller for which Aspire has a post processor file that includes ATC, automatic tool change. Aspire does not have a post processor file for LinuxCNC with ATC.

Oops…

There are two post processors for LinuxCNC in Aspire with no tool changing, one in inches and one in millimeters. I spent a moment thinking I might… Continue reading

LinuxCNC

LinuxCNCI did my homework with a lot of investigative reading and “Live DVD” testing. Today I made the commitment and installed LinuxCNC and the Debian real time Linux on the computer that operates my HB2 CNC router. It totally wiped out the Windows 10 OS (operating system) that was on that computer.

It was one of those “Popeye the Sailor” moments for me where he says, “That’s all I can stands, I can’t stands no more!” Then Popeye gulps down a big slug of spinach. For me it is a big slug of Linux. Ha!

There were several reasons and… Continue reading

Chips

The metal machining area and tools of my workshop have seen some action today. The Taig CNC mill has been busy cutting the 6061-T6 aluminum making 1 inch wrenches I designed for the Taig ER16 spindle and collet nut. I have been selling them under the KautzCraft brand in my store. It seems appropriate that the machine the wrenches are designed to fit are also making the wrenches.

The aluminum was purchased from Online Metals. They have a distributor in Grand Prairie, TX which is southwest of Dallas. Round trip from my studio was exactly one hour 30 minutes.… Continue reading
