Problems & Creative Solutions
Check out PART 1
After enduring a relentless, ice-age style winter, I am back to work on the CNC project with renewed determination.
Things were progressing smoothly until it came time to mount the proximity sensor on the Z-Axis. I had originally run the Y-Axis cable chain across the top of the Y-Axis. Unfortunately, this left no room for any of the sensors which protrude a good inch from the rear of the Z-Axis.
As mentioned in earlier articles, when you choose to assemble a CNC machine yourself, you may need to overcome these types of problems. Be prepared for some creative thinking and on the spot engineering.
After some thought, I finally came up with a solution. By adding a piece of 90 degree aluminum to the back of the Y-axis, I could move the cable chain back to give clearance to the sensors.
The original position of the Cable Chain interfered with the Z-Axis Sensor |
Now I needed to connect the top of the Cable Chain to the Z-Axis. I cut a piece of weld steel plate that reached from the motor mount to the new position of the chain.
Using the motor bracket as a template, I drilled and filed the piece to fit between the motor and motor mount.

Finally, I drilled four holes near the end of new piece so I could attach the Cable Chain with Zip Ties.
Don't forget to file down the sharp edges |
Now, everything has room to move. On to the next challenge!

I would like to thank you for posting such an informative post about cable sensors. I got some useful knowledge from this post. Thanks for posting it. Keep it up. roxtec distributor
ReplyDeleteCNC routers have gotten expanding mainstream over the recent a very long time for various reasons. One explanation is because of the minimal expense to plan and make one. It was not very far in the past that the CNC routers were just possessed by huge companies. These days, it's getting increasingly more typical to see end of the week woodworking specialists construct a little CNC router in their carports.
