Sneak Peeks of Future Projects / Random Stuff: www.instagram.com/savvas_papasavva

Steamed ahead today and finished the end-limits, re-fitted the dust shoe, drilled and installed the insert nuts into the sub-wasteboard, and cut and rebated the old wasteboard into its new shape. Here's an illustration of the toolpath for the insert nuts and if you swipe across you can see the dust shoe and and the wasteboard. #CNC #bCNC #GRBL #DIYcnc #LinearSlider #CNCrouter

The limit switches all around the machine are now wired into the emergency stop on the controller - via this 12v relay. So if I do something stupid and the machine goes to crash into itself - it will perform a hard stop. Ran out of space so I had to screw it to the side. Just need to square the machine and fit the old dust shoe, but I can't find the plastic tube that plugged into it. Slowly tidying up until it materialises. #cnc #DIY #electronics

There should be a word for the type of headache one gets when trying to think about electronics and Arduinos. On a positive, I fitted the sub-wasteboard, drag-chains, extended the wires, and the machine also homes correctly but I tried to wire up a end-limits (which will stop the machine crashing into itself) via an opto-isolator. The limits ran on 12v and the switches were all normally closed, and the signal from the Arduino was 5v normally open. But I managed to get some strange behaviour when the resume button wouldn't work unless held down after the machine had stopped. I can't tell what I'd done, but the 5v side of the opto-isolator wouldn't drop entirely to zero. Anyway I have a 12v relay somewhere so will try that when I'm next in. #CNC #CNCheadache #PainInTheCNC

Probably one of the more fiddly and annoying drive belt changes I do at work. Took me a couple goes this time and you can never really see the part your working on. Anyway for those of you into building table saws... marvel at the Felder K700 innards. Maybe if I ever finish my CNC machine I'll build a table saw. #Workshop #ToolInnards #MachineGuts #SawDust?#YouMeanMachineDandruff

This is as far as I got today. It's starting to look a bit cluttered despite installing the drag chains. I also fixed six micro limit-switches wired in series via the normally closed pins, which will eventually be attached to the hold feed button. Just in case I overshoot - which has been a problem, instead of crashing the machine, the limits should halt the movement and save me having to realign the axis. #CNC #LimitSwitches #GRBL #DIYcnc

Limit switches are in place although I managed to crush one. Went with a different method of attachment for the y axis compared with how I planned it on the 3D model. I'd still like to swap out the voltage dividers from the enclosure with opto-isolators when the part arrives - but that might be a bit of a job. The last thing I need to fit/wire today is the micro limit-switches, or at least decide now that will be done. Think I've misplaced the m2.5 machine screws for this. #CNC #NearlyOver #DIYcnc #Router #Woodworking #Machine
