Hello everybody!!
Finally I got the Smoothie working and I am programming new features with it. One of them is a thermistor with a timeout, just to set a temperature for a while.
For this, I copied the struct done in the code of TemperatureControl.cpp about the “set and wait mcode”. Well, it did not work at first, and I supposed it was because of my code. However, If I use the code from git (smoothieware-edge, the last update) and I try the set and wait mcode as it is said in the documentation, it also crashes.
This is what I see, I open a cutecom and I send the command (M109 S40) and it outputs an “ok” and the temperatures (T: 22.3 /25 @31, for example) and it appears several times. The temperature can not change, because I am not connecting anything in the pin (just a led to see if it flashes). After several times of this output, it stops and the leds 1,2 and 4 stay on (not flashing).
When I use the “set temperature” m code it works okey, it does not stop.
It also happens that when I am using the pid autotune It stops without finishing…
I hope I could explain my problem. I was wondering, do you know what is going on?
Thank you very much,
It works for absolutely everybody else, so look for anything in your setup that is different from the others. Connecting an actual heater would probably be a good start.
@Arthur_Wolf Well, I already tried with actual heater and good thermistor, however, it was always crashing. Now I found that if I disable the second Uart it works, if I enable, it does not. Could this have sense? Thankyou
second uart, or second usb/cdc ?
this one in config:
“second_usb_serial_enable false # This enables a second usb serial port (to have both pronterface
# and a terminal connected)”
so you are right, second usb
Do you really nned that ? it’s more of an experimental feature.
mmm… well, I am using one uart for debugging and the other to send commands… maybe I am doing anything wrong?
No I mean what kind of debugging ??
What kind? I don’t get it, sorry for my English. I am trying to test some code I am writing at the same time Smoothie is running…
So you added code to smoothie that sends text via the serial port ?
no, no, I added code to Smoothie to add a temperature control with a timer (to stand for 15 minutes at 200 degrees and then stop it). I want to check it, so I use eclipse to run the program in one uart and with the usb I use the pc with cutecom and send the command I “invented” for this task…
then it’s likely just a problem with your code.
Mmmm…well, I hardly think that because I disable all of my code and this problem happened when I used the generic temperature_control from the last git update…
Maybe you can try using MRI to see what’s happening ?
I already tried, but it seems like the communications on the port got blocked.
Yeah it goes over uart. It does not work… I dont receive the mri sequence through it i meant
Using an unmodified firmware ? What board are you using ?
