Once you have generated the G-code, you can simulate it in KMotionCNC.exe. I recommend watching the first 2 videos.Īll of the video are good and shorten the learning curve to use the software. Now that you have the machine ready and you have selected the router bits, you need to learn to use CAMBAM to generate your G-code. If you don’t remember anything else just remember the CNC router bits are only for wood and plastic but not metal. The bits shown in the photo are the 0.25 inch shank. Most places only carry the bits with 0.25 inch shank. Another benefit, Rockler also carries the bits with the 0.50 inch shank. They knew where everything was located, and they knew the product well. This store is their Superstore, which is huge. I purchased the bits from the Rockler Woodworking Store in Northgate, north of Seattle WA. I tested the End mill, 90 degree V groove, Tapered ball nose bits made by the “freud” company. If you run them at 100 rpms, the wood will chip badly. The wood working bit seem to work the best at 2000 rpms. The metal bits are designed to run at slower speeds, 100 rpm or less. The metal bits (especially end mills) do not work as well on wood. There is less of a chance of the bits clogging. The flutes are larger on the wood working bits so the sawdust can escape efficiently. To cut wood on your mill, it is best to use the CNC router bits made for wood. Move the edge finder up and place a 1 inch block between the edge finder and the known surface. Repeat the same process for the Y and Z axis.You will see the Counts on the “Axis” dialog. Move the joystick 1.0 inch on the x-Axis.In the KMotionCNC dialog zero out the X-axis.You will see a 0 counts on the “Axis” dialog. In the “Console” dialog execute Zero0 command.Move the edge finder on the X-axis to a known position.You show see the following dialogs together Run KMotion.exe and select the “Console” and “Axis” menu items.Place a ruler onto the table and insert the edge finder as shown.

What are the Counts/Inch for X, Y, Z axis of the table.Right? Does your machine have the correct Counts/Inch to move the expected distance?įinding the Counts/Inch for each axis, takes some effort. X should be negative and decreasing in value. X should be positive and increasing in value. Run KMotionCNC.exe and you will see the following dialog.

If you move Z down, the value will decrease.

If you move the Z axis up, Z should increase in value.

If you move the Y axis down from the origin, Y should decreases in value.

If you move the Y axis up from the origin, Y should increase in value.

If you move the X axis to the left of the origin, X should decrease in value.

If you move the X axis to the right of the origin, X should increase in value.

Your machine should follow the coordinate system as shown.

Does your machine have the correct Counts/Inch to move the correct location?ĭoes your machine move in the correct direction?.

Does your machine move in the correct direction? Or the direction you think it will move?.

Before you start cutting wood, you need to verify 2 things Setting up the machine did not require any special mathematical concepts to be applied. Machine Setupįirst of all, do not be intimidated by this section. The post is catered for people in the woodworking industry who want to use their CNC Retrofitted Mill/Drill to cut wood. If that were the case then very few people would ever use the machine. To use the CNC machine, the user is not required to have a PHD in Electrical or Mechanical Engineering. This post is geared for the woodworking types.
