Hello all you tinkering folk.
Not sure how I managed to delete all my accounts on my laptop during a changeover to a new one, but I did (bangs head on desk)… but back now
So… I hate the LCD controller, it just not that nice to use.
I have some Nextion touchscreens here, and they have really dropped in cost. If you can wait for China - £60 for a 7" touchscreen.
£30 -ish, gets you a perfectly fine 4.3" screen (which is what I am going to use).
So earlier tonight I started on a new controller. It will probably be like a tablet/dongle type thing… not sure yet.
Still bashing the code for the Pro-Mini that runs it, but I should be able to get this into a nice slim tablet style controller.
I also think I have got it to communicate with the Rambo without losing the LCD screen, or the PC connection.
Made myself some nice icons for specific functions I would like (such as full lift Z for tool change etc).
Has 5 pages (so far)…
Start splash page
Monitor page (Shows X,Y and Z in large Red LED style text. Plus spindle RPM)
Direct commands. Press a button to immediately action that G code request
Custom commands. A page with a keypad so you can enter your own commands, distances etc
Setup. Not sure what I need this for yet. Might bin this page.
The RPM is going to be monitored by either an infra-red or a laser optical sensor. I have both here, so going to experiment with both of them.
The photo with the X,Y,Z and RPM shown here, currently doesn’t have the numbers displayed yet.
I have been designing a vacuum shoe that wraps around the tool holder, rather than a single pipe going straight up. I have found the versions with the vacuum pipe going directly up the side of the Z mount loses you even more bed cutting area (due to it fouling the rails).
My slim wrap-around design doesn’t hit the rig, and will also include the spindle speed sensor and track the Z height with a small stepper motor, so that is can stay just above the part being machined automatically.
