My first CNC project will likely be my nCode logo, I generated the g-code and made a dry run video

Most of the parts are in, time to build a machine.
The machine itself is a CNC Mini Milling Machine Kit from www.modularcnc.com, the machining and cutting quality of the various parts was done in a minutiously with very thin margins and the end result is sturdy and very well built for a machine this small and at this price. I would recommend it for anyone who want to get into CNC. There is however no step by step instructions on how to assemble the machine and that is ok and not really required since detailed schematics of the linear slides and motor mount is provided and the rest is common sense. Take some time to familiarize yourself with the diagrams, parts and pictures before starting assembly.
The step motors, drivers, power supply, parallel breakout board, emergency shutdown button and various other electronic parts that you can see in the pictures have been purchased from ebay or DIY made.

Good evening,
I have designed and sent the schematics of the 3 axis unipolar stepper drivers to batchpcb.com for prototyping a few weeks ago. I have now received the end result: (click to zoom)
This controller will be powered by an Arduino Mini and will be accepting commands via I²C bus and Serial TTL 5V.
The schematics won’t be released until thorough testing is completed. I will start testing and assembly in a few weeks.
Cheers,
Marc

I bought a few weeks ago an old HP1740A oscilloscope from ebay for roughly 100$. The buttons, knob style and the size of it makes it really old fashion (I even found an inventory tag on it dating from 1984)… but hey! It still works, does a great job and this dual channel scope at 100mhz resolution is perfect for small electronic projects
The manual can be downloaded here: HP1740A Manual (I’m only putting a copy for download here for posterity, not trying to infringe any copyright or whatever.)
Some specifications from the manual:
- Width 335 millimeters
- Height 197 millimeters
- Depth 535 millimeters
- Weight 28.6 lb
- Input voltage
- AC and DC 250V (dc + peak ac) or 500V p-p ac at 1 kHz or less
- 50 Ohm: 5 Vrms
