Electronics Design & Embedded Software ⚡️| CNC Hobbyist 🔧 | Sometimes I post about stuff I'm working on 💡
Almost done, of course I'm missing a D-SUB connector for the back panel... 🙃

Finally getting around to installing the I/O expansion card for the wireless probe and lubrication system. While I'm at it, I'll also put in the driver for the 4th axis. ✌️

This is the size difference between my current probe (right) and my own wireless design. This would give me quite a bit more Z travel which is nice, plus the benefit of not having to plug in the wire every time. Still needs a lot of testing. I'm also just using a makeshift receiver at the moment.

I haven't posted much about the design yet, since I'm still tweaking things. It uses the common 3-leg mechanism for simplicity. Spring loaded contacts then connect it to the main board.

I made some progress, still far from done, but already doing some repeatability testing. So far I didn't break anything. 🤞

Can't let this become another 'It still needs firmware' project. 🙃

This cute little voltage regulator makes 0603 capacitors look huge by comparison. 😅

This happens when capacitors get a little too cozy during reflow. 🧐

Well infrared meaning the trigger signal is transmitted wirelessly. There are a few on the market that are mainly for bigger milling machines and are way too big and expensive for my use case.
I'm currently using this one from Sorotec but it's already a bit long for my machine and ofc wired.

First board assembled. 😇
Also decided to get the housing 3D-printed, rather than trying to mill it myself, for the time being.
January 18, 2025 at 7:21 PM
Finally working on some electronics stuff again. Got 2 boards that I need to assemble.
I've spent most of the last year building the CNC, so it's been a while. Maybe I should get some fresh solder paste. 🤔

Tried milling M2 threads for this part, which worked surprisingly well. I thought for sure I was going to break this tiny thread mill. 😅
But I have a few more parts in the works that also require M2 threads, so there will still be enough opportunities for me to break it. 🙃

Was looking through the config files of my cnc controller and found this.
Guessing this is used to check if the config file is complete?
Love it! ☕😄

I hate routing circular boards, even simple ones like this.
Parts at odd angles, free angle routing, uneven numbers... Uhhh nightmare fuel. 😨

This part will be interesting to machine. I'm not even sure this will even work with my current setup 😅. I'll need to add a 4th axis for sure.

Needed something to store my HSK32 tool holders. Couldn't find anything off the shelf, so I'm making my own tool rack. I think 12 slots will be enough for now, my wallet will thank me for this. 😅

The thought of crashing this beauty is a constant source of anxiety. 😰
December 1, 2024 at 1:13 PM
OP1 of the fixture plate is programmed. For OP2 I will simply screw it down so that I can machine all 4 sides at once and chamfer the edges, then for OP3 flip it and chamfer the back side. Very simple part, but I am still a bit worried about the 24 M6 threads I need to mill. 🤞
November 22, 2024 at 7:40 PM
Tools used:
- 16mm face mill
- 6mm 2 flute end mill
- 3mm 2 flute end mill
- 6mm 90° chamfer mill

We didn't crash! 😮‍💨
This worked out better than I had expected. 😅
I also put my action cam on the spindle, so I'll be posting a short video of how I milled this part.
November 16, 2024 at 8:26 PM
I need to machine 4 of these parts out of aluminium for a colleague. I just finished the CAM for OP1. This is the second part I've programmed using CondaCam, so I'm still figuring some things out.
I think this'll work ok, gonna order some 5083 aluminium stock and try it hopefully this weekend. 🤞

Just looking through some old pictures: I used to mill some of the simpler circuit boards myself.
I even tried using UV-curable mask and then milling away the mask with a spring loaded bit.
Thank god for the cheap prototype houses now! 🙏 Would not want to go back. 😅
October 24, 2024 at 6:01 PM
I've also recently finished my CNC mill and have a few things I need to manufacture on it. So I might be sharing some insight on the CAM side and milling the parts. ⚙️
October 24, 2024 at 5:19 PM
I'll try posting here as well in the future.
Expect mostly electronics related posts, containing pictures of tiny parts and circuit board assemblies. 📸
