where you at Caveman? Be good to get some help to get you started , and then you will be off and running.

What's giving me to poo's more is I can program cnc, lasers, mills, routers and draw in most CAD program's but I can't get a small circuit board to work.

Cavemanbrew, is it detecting the uno in devide manager? Can you hear the usb connect sound when you plug it in? I assume the board is powering up when plugged in?

In the arduino software, you have the right com port selected? Also the right board selected.. Uno, mega.. etc.

Thanks for replying

No there is no new device sound, or any sound when plugged in. No lights come on when plugged in, I checked the lead back on my printer and ok.

In the arduino software, you have the right com port selected? Also the right board selected.. Uno, mega.. etc, not sure and yes the ion is selected.

May be my uno board is foo bared ?

Oh well that sounds pretty drastic. If theres no power to the board when its plugged in.
I'd be thinking the worst.

get a couple. They are cheap

 

[djar007]

Have you gone into device manager? Is there a conflict sign against the device or anywhere? What software are you using on the pc side to detect the arduino? Have you tried an enhanced version?http://forum.arduino.cc/index.php/topic,118440.0.html

Cheers, will do

He is just around the corner.

Thx again.

 

[neo__04]

Even if the drivers were stuffed, it should still get power from the usb port i would think

 

[Cavemanbrew]

No got nothing at all, Ordered a couple, will advise if successful.

Done a bit of research tonight for anyone building mathos kit. Im going to be running a 3600w element and want to make sure everything is safe.
I'll be using IEC (pc power supply) connections. The ones in the kit are rated at 10a. I found some 16amp & 20amp connectors at RS components for only a few dollars.

Might be helpful for someone.

I've got my controller all together and the heater works fine but when I try to turn the pump on in manual mode it turns on for a split second then off. The arduino displays the P icon but no power is being sent to the socket. If I apply 12v directly to the plug it works.

The pump works in auto mode. Any thoughts?

 

[MaxN68]

Have you configured the system?

 

[PeteQ]

redwood turn pump during boil ON

I'm not sure if this is a bug or not, hopefully the pump will stop at the pump stop temperature in auto mode?

 

[xredwood]

Hi Max, yes I have configured the system and set the pump stop temp to 105 and it's cutting out right away even with the temp at 27 degrees

 

[MaxN68]

please write here your configuration I do the tests

 

[djar007]

PeteQ's suggestion to turn pump on during the boil fixes the pump on in manual mode. Good work mate.

 

[MaxN68]

In the afternoon (here is 8:40 AM) I reach to the code and settle this thing tied to Manual Mode and Pump on Boil

 

[djar007]

Nice one Max. I just tested it and when you turn it to on during boil to overcome the problem in manual mode the pump does switch off at the set temp (80c for me) while ramping up to boil.

 

[MaxN68]

Error found, it is change a number in a point of the sketch.
If anyone can prove, please contact me in PM I tell him where to be changed so that it can be tested immediately

 

[MaxN68]

I've changed my mind... If you want to try

You have to change a number at the end of void MANUAL_MODE:
...
if (mheat)PID_HEAT(true); //set heat in auto mode

if(mpump)pump_rest(8); //Forced Boil Stage for Pump Control

}CntDwn(TimeSpent);
}lcd.clear();
}

void WaitStart(){
...

The number 8 should be changed to 7
