G-Code (aka RS-274)
A standardized-but-not-very (think HTML extensions) language for machine tools. Originating at MIT in the 1950 era, standardized in the United States by the Electronic Industries Alliance in the early 1960s. Final revision in 1980 as RS-274-D. Other countries use ISO6983, DIN66025, Read more…
Couplers
From the ever popular CNCZone: Al_The_Man and Crevice Reamer: CR: Only 3 types of couplers offer true zero backlash connection: Solid. (which can cause problems unless PERFECTLY aligned, Helical, or Oldham. Helicals are basically solid couplers with some alignment flexibility. Make Read more…
Dual Closed Loop Control with KFLOP
The Dynomotion KFLOP controller can control 8 motor axis (either as 4 dual/slaved or 8 independent), complete with 8 dedicated hardware encoder channels (while any generic input could be used in theory for encoding, I understand the general I/O speed Read more…

More Stepper and Servo Wisdom
Again, from CNCZONE: Q.) What are the advantages/disadvantages between steppers and servos? A.) Step motors and servo motors service similar applications, ones where precise positioning and speed are required. The biggest difference is that steppers are operated “open loop”. This Read more…
Stepper Motors, Microstepping vs. Full, Increasing Torque Loss with Microstepping, Encoders on Steppers, Flywheels
There’s a lot of misconception about the subject (case in point: Excellent Reading). I also misinterpreted the information and made assumptions based on my (in)complete understanding of it. As such, here’s some excellent sources of information regarding such: CNCZone: Microstepping. The Read more…
