Making a CNC Milling Machine – Increasing the travel
Making a CNC Milling Machine – Increasing the travel Part 3 I have been working on making a CNC milling machine from a Grizzly G0704 manual milling machine. Welcome back to my blog. I have looked at several modifications to the Grizzly G0704 and one that seem really useful is increasing the travel on the Y and Z axis. Increasing the travel will require some pretty serious modifications to the existing castings and will definitely void your warranty. Increasing the travel of the Y axis will require that I
The Warp Drive Project Story – Mach3 Motor Tuning Video
Mach3 Motor Tuning Video The Warp Drive Project Story – Faster CNC Router Part 3 I just found an old video I planned to post to Youtube a few years ago when I was developing the Warp Drive Project. For some reason I never published the video then, but I decided to do so now. I was doing motor tuning to find out how fast I could make the Z axis go. Back in the early days this seemed fast. Since then I have increased the speed by a factor of 3. The original Warp Drive project parts were made […]
Motion Control
I recently had a hard drive controller failure on my CNC computer and had to decide to either replace the motherboard or get a new computer. Most new computers don’t have a printer port anymore so it is getting difficult to find a replacement computer. The old CNC computer used a parallel port (printer port) for Motion Control. You either need to purchase a separate Motion Control add-on card for the computer or you had to try to make a USB adapter work. USB converters by themselves don’t work with Mach3. Mach3 needs to be able to control the […]
Edge Lit CNC Sign Project
Recently I made an Edge Lit CNC Sign Project for a school musical. The theater director asked if I could make a lighted sign for the production in a short period of time. The curtain would raise in 3 weeks but the materials couldn’t be purchased for a week and a half. I took on the task and decided to get a head start on the project. I took the artwork the play director provided and began the design work for the sign using Vectric Aspire. I scanned in the image and then created vectors for the artwork. Then I […]
