Also trying out a new GUI, I think I like this one better than the other one so far.

These pics? I have even flipped them in the editor and they still post upside down. Apple is a product I love to hate.

Like that big screen - Lot better than the 20X4 LCD display I'm using - - Found a new toy - a SNES controller, four extra buttons, now I can button in X Axis distance along with Y Axis and Jog feature.


void getButtonData()
{
digitalWrite(nesLatch, HIGH);
digitalWrite(nesLatch, LOW);
for (int x = 0; x <= 11; x++)
{
bitWrite(nesButtonData, x, digitalRead(nesData));
digitalWrite(nesClock, HIGH);
digitalWrite(nesClock, LOW);
}
}

My OCD is colliding with my ADD . . .

I've snapped two of those spring type couplers - they argue and win when I turn the hand wheel while the stepper enable is on Sticking with the little Lovejoys . . .

Hmm Etch-A-Sketch - two small steppers sitting on the shelf? I see more useless but obsessive compulsive time coming up . .

I'll use it till i breaks. Yea screen is my wife's old laptop. When I got a new one she had to have a new one too. Only fair. She broke the switch on it so I took it apart and wired a tiny momentary contact switch that I salvaged out of something and "fixed" it. Now it's my garage computer. I use it for the arduinos and stuff when I'm out there. I can't throw stuff away. I salvage and give it new life. Lol thinking of figuring out the limit switch noise this weekend. Sorta put it on the back burner and got destracted fixing the y axis...doesn't take much to distract me. Also been playing around trying to learn Python. Don't know why but thought it might come in handy one day. I'm weird like that. Nickname back when I was in college was random man because I either had one or knew how to for everything. What happens when you don't waste your childhood playing video games. Speaking of which I was thinking of digging out my old nes controller. I have one somewhere that I used to control a little car I made twenty years ago. Yours made me think of it and had me wondering. Don't have a control dongle might need to change that. Also thought about using the wii controller but don't really need the accelerometers in it so prob want do that. Got to get my limit switches in place before I do any more milling but I'm itching to get it going again. Prob will take me five minutes to fix and weeks to research to pick best option. You know how that goes.

Just curious are you writing functions or just one long code? Functions make it more modular/ configurable. Easier to debug too.

The gui is called grbl panel. Free download From get hub. The other one I was using was universal code sender. Both I think we're meant to use the Gshield I'm using to control my steppers which plugs into my sacrificial arduino uno. I keep another uno with me most of the time for whatever. Told my wife it's the electronic version of a Swiss Army knife. Use it for all kinds of stuff if not just for entertainment. Here is how I entertained the 6 yr old earlier this week clicking relays and blinking lights...I admit I was entertained too.

I have a limit switch that is acting up - Routed with shielded cable so shouldn't be picking up noise - Think I'll put a small delay in the sw read and/or change out the switch . .

Functions - That way when I break something it's just inside the function I have to look - - That's bad, I actually sorta know what i just wrote . .

case btn_Right: // 191 ---> Button
RunRight();
break;


Controller is apparently just a shift register - each button or combination of buttons spits out a unique number - looking at one of those little membrane keypads - Tie it to the guts of a standard NES controller and go from 8 pins to three on arduino.

But if it ain't broken, I'm not trying hard enough.
I just had to reroute the car wiring, really just had to - - Wasn't broken, everything worked fine . . . You know where this is going . .

Ok off to try and cut a Bezel cover for the 20X4 display - One that actually sorta fits . . . Been put'n with it to compensate for the backlash

{ // Three

for (int jog = 0; jog < (stepsY * 1440); jog++) // 32 steps = 0.001"
Stepper.CCW(stepY, dirY, 600);
delay(150);
}
. . .
{ // Five

for (int jog = 0; jog <= (stepsY * 1453); jog++) // 32 steps = 0.001"
Stepper.CW(stepY, dirY, 600);
delay(150);
}

OOPS - the bride says her A/C quit - Like I know when the vacuum pump and gauges are - - - Guess my day just got rescheduled . .

These are about 4bucks on Amazon. Really flat and the back has a peal away adhesive. Yea I have a water pump to change in the near future. Ordered it yesterday for the Mrs. I'm thinking about trying a choke before I bust out the resisters and caps to make a filter. Mine goes into alarm the second the table starts moving. I don't have an o scope anymore ( need to change that soon) to find out where the noise is coming from. Doesn't need much dampening so maybe a ferrite choke will do? Might have to play with the number of wraps though. Just seems less invasive and doesn't involve anymore soldering but as always I have a back up plan. My ac stopped working years ago in my company car - I'm do for a new one- but as long as the Windows work I'm good. I've been doing a little research on backlash comp too. The z has 1.4mm both directions. Y should be almost 0 now and x...well I'll have to remeasure because I don't remember. It's easy to add it in the Gcode in post processing but I like to do things the hard way I want to automate the adjustment. Direction change + compensation = total movement.
