I am still having the same problem. The only way around this is after you connect the front end software disconnect it then reconnect it. I have to do this every time.

in reply to: Double PID for Temp Control #3782

I have made my IR reballing reflow station I am using osPID to control the top heater and also using a Rex-c100 PID to control the bottom. I am unable to get a stable preheat as the Rex-c100 is a bad cheap controller. I have been told that I can run the bottom and top separately using just the osPID can this be done with my machine. Bottom preheater is running 4 ceramic IR plates each is 400w and connected to Fotek SSR -25 DA and then to Rex-c100 PID. The top has 1 IR plate 250w also connected to another Fotek SSR -25 Da and this is connected to ospid. Can a profile be run from osPID to controll the two different heats. His is a picture of my machine it’s not much to look at but it’s working. With only problems with bottom preheat. How if it can be done will it connect or wired.http://img694.imageshack.us/i/imagecfp.jpg/

 When preheater got motherboard to temp 110 I ran this profile
I got this reading with TC  around 3mm from chip i was practising on
One thing I am having issues with is when I select a profile from list in osPID front end and select my com port and then connect I then click send profile but nothing happens. The only way I can get the profile to send and run is to disconnect and connect straight away this then runs 100% without fail. Maybe error in software.

This was the ramp profile. I changed first Step from 100 to 130 and it did help as you see in picture. Only thing was temp on ospid and tc beside chip was that they were around 30oC of a difference. http://img685.imageshack.us/i/imagedwv.jpg/
This was the step profile 30 min before didn’t look good compared to ramp profile.

And here is my setup not a finished project as you see but working and like everything else a lot of testing.

I am having problems with loading a profile from pc to ospid. When i select a profile i select send then when it completes i run and it works then say I do another test in 30 mintues time and load another profile the same way, it wont load up and nothing shows on status bar but its running on the ospid but not on pc. This has happen a few times. I would rather use the pc for seeing what is happening rather than looking at ospid it seems to me i am controlling the reflow better. That is my option.

This is my first go at running profiles on my Homemade IR station top plate controlling this is step profile.

This is ramp profile. I didn’t get Autotuning to work to Autotuning at 235.
20oC Temp difference between osPID TC and thermometer TC both where within around 5mm of each other sitting beside chip I was testing for solder liquidous. Still learning about osPID which is a superb gadget if thats what you to call it.

So is Autotuning better activated before any profiles are implied on the ospid

I am a bit confused on the reflow chart to edit for my own profile I have tried to set up my profile but unable to succeed any help is good. This is my profile that I am trying to upload. To reflow profile so I can run from front end.
Time. Temp.

Hi guys, I believe I have fixed this issue. from the commit note:

the problem:
– github adds a hash to the end of the download zip (e.g. “-da74de9”)
– when unzipped this hash is now part of the folder name, so it doesn’t match the .ino name
– a new folder is created without the hash, and for some reason the analogbutton files are not copied
– the newly moved .ino throws an error.

the solution:
– I created a osPID_firmware sub-folder and moved the program there. this way, when un-zipped the hash will be added to the outer folder, not the actual program folder

Yes this does fix the AnalogButton Error

hey,
when i open the osPID_Firmware.ino within Arduino1.0 it tells me that it needs to be in its own folder. So I click OK. It creates that folder, so I promptly move all the other files into the same folder (I get the following error even before moving the files).
Then I get “AnalogButton does not name a type”
for this line
AnalogButton button(A3, 0, 253, 454, 657);

I assume that the AnalogButton stuff is an issue with my libraries….fyi, i still have Arduinio .223 installed, since i have sketches that only work there.

thoughts?

otherwise, awesome kit! can’t wait to integrate it in to some crazy projects…

Have the same problem and can’t get osPID firmware updated keeps hanging on analog button here is a picture of the error http://img138.imageshack.us/i/imageswv.jpg/

The firmware is coming along nicely. I’d say profile functionality should be available within a week. Here’s a little teaser: https://twitter.com/#!/rocketscream/status/188990752435617792/photo/1

Good news. Just ordered mine today for using on my homemade IR rework station. Hopefully when it comes all firmware for reflowing will be out.

in reply to: Ramp Soak and stuff #3732

How’s things going with the firmware Brett

for example I might like to ramp from 32 degrees C to 47 degrees C in 45 minutes.

ah ok, you may be able to approximate the behavior you want with the next firmware update. designed mainly for reflowing, you will be able to specify a recipe of SP ramps, steps, and/or waits that you can execute with a single command.

Hi Brett any ideas when the firmware will be out.

Can’t wait to order mine
