Prusa mendal I2 Pronteer face Marlin error

[jakers181008]

Hello people,


I have a prusa mendel I2 printer with a ramps 1.4 board, with one extruda and one heat bed and a Ramps GADGETS3D Sheild. Marlin firmware

My issue is when i connect up my printer to pronterface with it plugged into power and usb, it comes up with this on the side console:

And the bit that concerns me is the obvious part " Error:Printer stopped due to errors. "


i have a Acer Aspire 64 bit laptop which i'm using, the printer is set to 115200 baud rate on port 5. here is my copy of firmware which i'm using just incase it is something in there.
My Marlin.zip


Also before i was using splinter or something along those lines, and there was no error (but the motors wouldnt move, but make a noise like it was jammed or not strong enough. but since i got the LCD shield i read that i needed marlin, (hoping this would kill two birds in one) but it seems to have created an error. as seen above.

i hope you guys can help me, if you need to you can email me at Jakers181008@gmail.com

if i've missed anything out please just say and i'll fill in the gaps


Thanks in advance

Kind regards

The error being reported is MAXTEMP triggered. The leads for the hot end thermistor are likely shorted together or the configuration.h file hasn't been set up properly for your printer. What is pronterface reporting as the hot end temperature?

[jakers181008]

Hi Printbus,


please find screen-shot of the temp graph seconds after connecting the printer. is there a way to check the quality of the thermistor as this was a pre built hot end, would it be something in the firmware that could be causing this as it didn't come up with this error while i had splinter or something like that (sorry forgot if that is actually the name)

Did you ever say where you got your Marlin firmware? The good thing about Marlin is that it is very flexible - it is configurable to support a wide range of printers. The bad side of Marlin is that you have to either find a variation pretailored for your printer or you have to spend time working through all the configuration details. My guess is that there is a lot of work to do to get Marlin properly configured for you. An earlier post of echo output indicated SD init fail. The extruder heater not working and issues with the beeping could be signs of output pins being incorrectly mapped. Motors are just making noise because you might be trying to drive them too fast.

When you get the LCD beep, what is displayed on the bottom line of the LCD screen? The bottom line is for status messages from Marlin. Maybe there's a hint there on what the beep is about. I'd personally work through that issue first, since an error condition might be inhibiting what Marlin allows you to do with the printer.

One thought would be to start with a copy of the Marlin firmware preconfigured for MakerFarm reprap printers here - http://3dprintboard.com/showthread.p...s-enhancements. If nothing else, compare the details of the configuration.h and pins.h files between that firmware and your firmware. Where there are differences, you'll have to research or come back with questions on what would be the best for your printer. Right now, of course, we know little about what you actually have for a printer.

I'm in the middle of a number of unrelated projects, and the next several days won't provide me the time to dig into your files more than I have. Maybe someone else can jump in and help.

Hiya, thanks for the help printbus, on the lcd at the bottum it actually says mendal ready, but still making the beeping, i'm guessing that is because it doesnt have an SD card in yet, dont want to put one in yet just in case. i'm sorry but i dont remember where i got the firmware from, i just had a look at the one you have linked, but it seems that it is for I3 for a different printer with auto bed level... far from what i have i have this make here: http://www.nextdayreprap.co.uk/prusa...free-download/ only difference is the Ramps 1.4 with lcd sheild i got this one here: http://www.ebay.co.uk/itm/3607855687...%3AMEBIDX%3AIT

hope this info helps out finding an issue, i can post more pics or videos if you guys wants some of the build? just say what you need to see and i'll upload it for you


Thanks for all the help, i have gotten much further in the last week than i have since last christmas....

Sorry about hitting you with multiple posts, but set aside the motor issues for now. Once we think the panel is working OK we can get the heater controls sorted out.

[printbus]

The normal Marlin config has the primary extruder heater on D10. You show it wired to D9.

[jakers181008]

ahhhhh, will re wire that now

unless there is a setting in the config that i can just reassign the wires?

[printbus]

The screen shot came out too small to be readable. I do question some of the configuration.h settings in your firmware zip file. You have motherboard type 33 set up, and later these definitions -

#define TEMP_SENSOR_0 -1
#define TEMP_SENSOR_1 -1
#define TEMP_SENSOR_2 0
#define TEMP_SENSOR_BED 0

The -1 on TEMP_SENSOR_0 says the hot end is measured through an AD595 chip. Is that true? If not, change the -1 to the value for the thermistor your hot end supposedly uses. There's a table in the configuration.h file with values; repraps are usually set for a value of 1.

Motherboard type 33 means there's only one extruder, so TEMP_SENSOR_1 should be set to 0.

If your printer has a heated bed, TEMP_SENSOR_BED should be changed to the value for the thermistor used on the bed. Again, repraps are usually thermistor type 1, but it depends on what the manufacturer used on your heat bed.

AHH thank you i will try that right now, thanks!
