CNC Probing

CNC utilizes contact probes for various purposes: Edge Finding Zero Setting Digitizing (point cloud) Mapping Several major companies exist (example Renishaw) to service major industry; less so for home or prosumer markets. Of late, two have captured my attention. Kurokesu AKA Saulius Lukse  from Lithuania (http://lukse.lt/uzrasai/) (two production runs have been produced so far, and a […]

Driving a Ballscrew – Servo vs. Steppers

Excellent example of Servo vs. Stepper vs. Feed Speeds. This is by John Dammeyer, developer of the Electronic Lead Screw Project: Electronic Lead Screw Main Page …now I did some experiments as a result of this posting subject. I found if I turned the handle for moving the carriage at what was a pretty normal speed it went 10” […]

KmotionCNC Conditional Logic

The GCode Interpreter included with KmotionCNC is more bare-bones than the extended on in LinuxCNC, and some people were discussing how to work-around this perceived lack. I found a link on CNCZone that outlined a method (albeit on Mach3) of performing conditionals (as Mach3 also does not support the higher-functions in LinuxCNC). At one point, […]

Brief History of G-Code, Numerical Control, and G-Code Complilers

G-Code (more precisely G and M Code, more formally, RS-274D or other names) is a programming code that dates back circa 1950, and was originally developed to control mechanical machining operations using paper tape. It shows. The last ratified standard was in 1980, and the last open source variant in 2000 (RS274NGC_3.pdf – 2000). Most […]

Motion Controllers (Software and Hardware)

CNC toolchain: CAD -> CAM -> G-Code PostProcessor -> Motion Controller -> Drives A Motion Controller is, well, just that. A structure to control the coordinated motion of at least a singular CNC axis. Motion controllers can be software or hardware based. On the hardware side, the continuum runs from as simple as relay logic through small […]
