Posted · Error:Temperature heated bed switched off. MAXTEMP triggered !!

hello, yesterday i,ve updated the cura software from 14.03 to 14.07 on my windows pc and install also the newest marlin firmwire on the board.

when the update was done i get stuck in the error: Temperature heated bed switched off. MAXTEMP triggered !!

the only thing that my ultimaker original with board number 1.5.7 and self build heated bed do, when i switch the power on: is getting pressure for about 1 second on all the motors and after that loose it for 3 seconds and repeat that (loop)

before i drive the same hardware for 3 months with cura 14.03 an secondary marlin firmwire with no problems.

whats going wrong with the new software ?

    http://umforum.ultimaker.com/index.php?/topic/6016-possible-problem-with-cura-beta-um1-heated-bed/

    Try flashing with your custom built firmware. When you select self built bed, Cura will flash a version of the firmware intended for the soon to be released heated bed kit from Ultimaker which used a different type of sensor for the bed temperature. This caused the firmware to flip out

    You will (probably) need to pull the arduino out and reflash using the Arduino IDE and your self built custom firmware if you can't do it in Cura.

    howto build and load a custom firmwire

    visit the website http://marlinbuilder.robotfuzz.com/

    select your brand

    choose your options (100k is the number of resistance from your bed temperature sensor)

    the rest i dont change

    click build

    right click on the HEX file and choose save as

    open cura

    choose machine>install custom firmwire (and load HEX file)

    done

    this is what work for me good luck (please correct me when im wrong)

    Hi All

    I thought to be smart the first time after I installed the my custom HBK and in Cura selected the option to install the “custom hbk firmware” (so I thought) that came with Cura 14.06. Ups.

    After initially showing the bed temperature etc. it shows a strange error message (MAXTEMP / Error, can't remember) on the UltiController and then hangs! So clearly the wrong firmware. No more connection anymore via computer / usb. Panic (a bit)! Also after restart, the UM hangs at the same point.

    Solution that worked for me (vs pulling your Arduino):

     

    1. disconnect your USB Cable, turn the UM off
    2. In Cura click "install default firmaware..." so the dialog appears "Please connect..." and only then connect the usb cable to the Arduino.
    3. As soon as the Arduino starts powered by USB (probably before initialising), it starts the firmware update from the computer
    4. after the update you should be ready to flash any other / custom firmware

     

    Hope that helps at least some of you with similar issues.

    Martin

    Good info Martin, I couldn't find a way to recover from installing the wrong firmware that didn't require me to remove the arduino. It might have been the USB hub that I use.

    If it happens again, I'll try your sequence.

    Same here..

    Upgraded to cura 14.07 and it instantly gave me a MXA TEMP BED error.

    So I went to http://marlinbuilder.robotfuzz.com/ and build my own hex file.

    Uploaded to the machine and now working fine!

    Thanks for all who replied here on this thread! You saved me a lot of trouble shooting!

    Hello. I need your help!!! I also have error at the maximum temperature of the hot bed. I generated the code on the site http://marlinbuilder.robotfuzz.com/but I can not download the hex file. I have 10k thermistor.

    The only 10k thermistor table that comes with Marlin is this one:

    https://github.com/ErikZalm/Marlin/blob/Marlin_v1/Marlin/thermistortables.h

     


    #if (THERMISTORHEATER_0 == 4) || (THERMISTORHEATER_1 == 4) || (THERMISTORHEATER_2 == 4) || (THERMISTORBED == 4) //10k thermistor
    const short temptable_4[][2] PROGMEM = {
    {1*OVERSAMPLENR, 430},
    {54*OVERSAMPLENR, 137},
    {107*OVERSAMPLENR, 107},
    {160*OVERSAMPLENR, 91},
    {213*OVERSAMPLENR, 80},
    {266*OVERSAMPLENR, 71},
    {319*OVERSAMPLENR, 64},
    {372*OVERSAMPLENR, 57},
    {425*OVERSAMPLENR, 51},
    {478*OVERSAMPLENR, 46},
    {531*OVERSAMPLENR, 41},
    {584*OVERSAMPLENR, 35},
    {637*OVERSAMPLENR, 30},
    {690*OVERSAMPLENR, 25},
    {743*OVERSAMPLENR, 20},
    {796*OVERSAMPLENR, 14},
    {849*OVERSAMPLENR, 7},
    {902*OVERSAMPLENR, 0},
    {955*OVERSAMPLENR, -11},
    {1008*OVERSAMPLENR, -35}
    };

    The number on the right is the temperature in C. So if room temperature is around 20C then you expect the ADC reading to be 743 (out of range of 0 to 1023 which corresponds to 0 to 5V) so that means you should have 5*743/1024 or about 3.5 volts yet it is reading 0 volts or 5 volts to get that error.

    Check your wiring with a volt meter. Did you install the 4.7k resistor? Is it the right resistance? The circuitry is very simple - it's just a 2 resistor circuit. Also known as a "resistor divider":

    http://en.wikipedia.org/wiki/Voltage_divider#Resistive_divider

    Where one resistor is at 4700 ohms and the other (the thermistor) roughly 1.9k at 20C.

    If you don't understand this and/or don't have a multimeter, find someone who does.

    These numbers don't seem quite right to me. I suspect this table is meant to work with a 10k resistor instead of a 4.7k resistor.

    There are many 10k thermistors out there all with very different properties which mean each manufacturer would need a different table. Same thing is true of 100k thermistors. So I suggest you get only the recommended reprap 100k thermistors.

    Much more information here:

    Thank you for your information, gr5! My heated bed temp sensor died and I am awaiting a resolution from support. In another thread, someone mentioned soldering in a 220ohm resistor and that got the machine to work again, but it didn't work for me. I figured something more serious was wrong. After finding out there are different valued thermistors used, I decided to connect a potentiometer to the bed and see if I could find a range that worked. Jackpot! :) a 120ohm resistor registers as 42c~43c and 138ohm as around 110c. I put a 120ohm in and printed up a small 8 minute object in ABS. Went into the tune menu during printing and just kind of guestimated turning the heat on/off by alternating the desired temp between 40~45. Will attach my Fluke's temp probe tomorrow to hopefully get closer approximation of the temp of the bed.

    I hope Ultimaker either sends me another thermistor for my U2 (or tells me the value I should have so I can buy a few from Digikey) or another heated build plate soon... but being able to print again is awesome!! Thanks again!

      • S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
        (Sorry, was out of office when this released)

        This update is for...
        All UltiMaker S series  
        New features
         
        Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.
