Connecting to pronterface

Dcleonard 2017-02-02 00:21:19 UTC #1

Ok it seems I got it all back to get her and all. Arduino uploaded the firmware just fine. However, pronterface will connect to it when the power is off. But it hangs on "connecting..." When power is on. What do I do?

you don't have both apps open at the same time by chance do you? I think they don't play well together...

Dcleonard 2017-02-02 01:28:12 UTC #3

No I don't have them open at the same time and cure will not connect to it either.

only other idea is baud rate set the same in all?

Dcleonard 2017-02-02 02:03:32 UTC #5

How do I do that? Sorry I'm pretty new to all this

I know you have already said but please re-check that the baud rate is set correctly. from the menu go Set > Connect > 250000 then Back. Try that and let me know how you go. A video of mine is here https://www.youtube.com/watch?v=C_4LbaNXVTs23 at about 2:41

When the display says ReadyPrint it just means that it has got power and nothing more - very misleading.

BTW, i am still building my printer so you are ahead of me but i am well read in these forums so...

Thanks. I work12 to18 hours a day and only have every other Saturday off. It's hard to find time to do all the research

PaulS 2017-02-02 12:54:03 UTC #10

no worries, just let me know if that helped

I got it together and running. When using pronterface, all the axis' move just fine. But when I hear up the hot end to the set 210°, it goes all the way to 270 and gives the overheat error on the LCD. Also when I try to print with Cura, when it heats up it goes to about 265-270 before dropping down to the set temp. It also does not extrude.

Dcleonard 2017-02-03 05:41:26 UTC #12

And yes, I already had the baud rate set

glad you got past the connection hurdle. any idea what the issue was? i like to pay it forward in case other read this later. My printer is almost alive so i may need some brownie points soon

One of the end stopps wires were crossed. I unplugged everything and it connected. So I disconnected, plugged one thing in, reconnected. Repeated untill it wouldn't connect with the crossed plug. I had tried to run pretty and neat ribbon wires because I thought it would make it easier to run through the cable chains and it was. But getting all the connector ends wired up correctly was a pain in the butt.

Now I have to figure out why it goes way past the set temp when heating up. It goes all the way to 275 and shows thee max temp warning. Even when it's set on 185.

bit of a stretch but i saw a youtube on thermisters and you might have 1 leg grounding out. Best guess but easy to test. unplug from board and check resistance between 1 leg at a time and heater block. I think there is a PID auto tune for the hotend too but don't hold my feet to the fire on that. Good luck

@Dcleonard I am with @PausS regarding PID tuning.... If the temperature swings way high, poaaibly way low, but eventually settles on the set-point temp, my guess is the PID tuning is off. I believe you can look at the Folger stock Marlin PID tuning parameters and use those as a starting point. Search Marlin Configuration.h for

#define DEFAULT_Kp

P 24.8
I 1.67
D 92.03

You should see similar in your Configuration.h file.

Good luck.

@MadDog can't type.

poaaibly = possibly

Sorry.

Thanks. I'll check it out as soon as I get a chance
