CNC Enclosures

Posted · 2 Comments

Part of being able to mill/lathe indoors means having a good safety system set up. When I first purchased my Taig Mill and Sherline Lathe, I wanted to enclose them to catch any shrapnel. Since I started playing with Misumi parts for my MendelMax, I thought I could make a great enclosure using it. IContinue Reading

Lathe Job

A friend asked me if I could bore out a wheel adapter for a tire machine on my lathe. I hadn’t done much steel work, but figured it was a fun thing to try out. The results turned out nicely.

I2C RGB Led Adapter

I ran into a challenge recently where I didn’t have enough spare pins that could PWM on ramps. I want to add LEDs for lighting and to signify certain events. To work around the issue, I decided to make an i2c-rgb led adapter. I2C lets me have up to 127 devices. I plan to makeContinue Reading

Easter was always a fun time growing up. We dyed eggs for nearly every Easter. Now that I have children, I want to do the same. The kicker is that I want to do it with a twist. When I ran across the prospect of an Eggbot, I knew that it was perfect for theContinue Reading

At our local hackerspace we have a waste oil heater that some of our members built.  Right now we are using a stainless steel bowl for the burn plate.  We needed a proper solution.  To do that, we got a piece of aluminum round and needed to create a bowl in the middle with aContinue Reading

Tonight I got the wiring and configuration done for the WidgitMaster/grblShield combo.  You can see a video of it running a square gcode pattern below.  Next I’ll be making an enclosure for the electronics and setting up the necessary fixtures.

For my PCB Mill, I wanted to use something more portable than the SDTR-4C that I use for my Taig Mill and Sherline Lathe.  I was originally planning to use a RAMPS setup, but for a few reasons I went a different way.  I won’t go into it here, but may later.  Below is aContinue Reading

WidgitMaster Router

Posted · Add Comment

I’m putting the finishing touches on the widgitmaster router that I bought long ago. I started by turning down an acme screw to replace one that was missing in the package.  Then I had to make 2″ couplers because the nema 23 steppers had short shafts.  Finally, I needed to mount my Wolfgang spindle toContinue Reading
