CNC Mill Update - 2023

CNC Mill Update - 2023

In this update post I will describe a few of the modifications and improvements I’ve done to the mill. I occasionally get emails requesting information about modifying the mill and I hope this post will be helpful for anyone else working on a benchtop mill.

Loop Antenna Copper Jumpers

Loop Antenna Copper Jumpers

I am planning to machine some copper jumpers to go between the copper loop and the vacuum capacitor. These can be soldered (or brazed) to create a solid connection with very low resistance.

D&D Miniature and Dice Holder

D&D Miniature and Dice Holder

As a Christmas present I hired someone on Fiverr to create a 3D model based on the image and I 3D-printed a couple of custom miniatures. I also created a wooden dice tray and miniature holder for storage out of walnut.

LCD Control Board for SX3 Mill

LCD Control Board for SX3 Mill

The LittleMachineShop control board replaces the button board built in to the mill, so when the spindle control board is connected the buttons and LCD built in to the mill are no longer functional. I designed a drop-in replacement for the button board to help add back some functionality.

In 2017 I acquired a Shopfox M1111 benchtop mill. It has an intermittent issue with the spindle motor, but is otherwise mechanically sound. This mill is very similar to the Grizzly X3 mills and is suitable for light-duty milling in aluminum. Leadscrews These mills are commonly converted to CNC machines

Robotic Arm - Part 2 - Assembly

In part 1, I shared some of my notes about the BOM for the Moveo robotic arm. In this article I'll share some pictures of the assembly. All of the plastic parts on the Moveo are 3d-printable. I experimented with and without support material and found the parts printed generally

Building a Robotic Arm - Intro and BOM notes

A coworker recently told me about an open-source 3D-printable arm design available online. Its called the "Moveo" from BCN3D. You can find more info about it here. I am going to write a few articles with my experiences building the Moveo as-is. I'll detail some of the parts I chose
