Direction reverses when moving from a stationary table (the CNC Router) to a moving table (CNC Jr.). Routinely clean cutting table, and the gears of the track that the machine runs on. Debris that is compacted in the teeth of the gears can cause unsteady motion of the machine, leading to poor performance.

Omnitech Selexx Spectra CNC Router Narrated by VP of sales for Anderson America, David Paine. For more information on the Spectra visit. The Selexx Series from Omnitech Systems is their main line “Light Industrial” CNC routers. The Selexx Series is distinguished in the CNC manufacturing marketplace by exceptional weight, speed and a configuration designed to meet the needs of multiple manufacturing environments.

All right. More CNC machine basics here. Today, we’re discussing the various modes of operation your CNC machine can use.

Let’s get right to it:

Manual Mode

Note that this differs from Manual Data Input (MDI) mode. In manual mode, your CNC machine acts like a standard machine. You can operate it just like you would any other machine that doesn’t use programming. You can push buttons, turn wheels, and turn switches on or off.

The difference between manual mode and manual data input mode is that with MDI, you can do certain things that you can’t in manual mode. More on that in a second.

Manual Data Input Mode (Also Called MDI or MDA Mode)

In this mode, you can do some programming and data entry. However, everything you enter will only be done once. If you need all the functions done again, you’ll have to program them again.

The advantage of this mode is that you can do manual operations that simply cannot be done in manual mode. Some CNC machines, for example, don’t have manual controls to change the spindle speed.

Single Block Mode

Each CNC program is made of blocks. They may be numbered something like N20, N30, and N40. When you enter this mode, just a single block of code executes. Additionally, this means your CNC machine only stops moving on its access. For example, the machine spindle keeps turning, and coolant continues to flow too.

Edit Mode

Just as it sounds, you can enter programs in your CNC machine’s memory, or you can modify current programs. Programs are usually organized by number, and you can make the program you want active.

You can also insert new info into the program, alter its current info, or delete info from it. Some, but not all, CNC programs allow you to cut, paste, find, and replace data just like you would in word processing software.

Automatic Mode/Program Operation Mode

Again, no surprises here. In this mode, you get to find out how well you did with creating your program. So, take a deep breath, and execute yours. Most CNC machines allow you to see the commands executed as they happen. So, if you notice a mistake, you will be able to easily identify where it is in your program.

Those are your basic modes of operation. Feelin’ ready? Awesome. Time to give your CNC machine a try!
