Bed heat shutoff

[SeventhDread]

Hi, this happens with the Anycubic Firmware too, but I am currently using Marlin and like it, so I would love if you can help me also this is not really a bug but I thought it suited bug more than a feature request.

I am trying to print with ABS but when I try to heat the bed to 110C when it reaches like 102C I get this in terminal through octoprint: I believe this is to do with a timer because it takes too long to heat up, and I am wondering sence you made the Anycubic Marlin firmware if you know how to I edit something to extend this time?

Yes, you can change the timers:

https://github.com/davidramiro/Marlin-Ai3M/blob/master/Marlin/Configuration_adv.h#L100

Raise THERMAL_PROTECTION_BED_PERIOD and WATCH_BED_TEMP_PERIOD, lower THERMAL_PROTECTION_BED_HYSTERESIS and WATCH_BED_TEMP_INCREASE.

Since this is not really a bug, I am closing this issue, but feel free to report back with any further questions.

Hi, thanks but how much do I increase/decrease them by?

Also when trying to upload it I got this error message: (I put it in a notepad file as its long) errorreport.txt

[davidramiro]

Hard to say. Ideally, if you're printing ABS you should have the printer in a well insulated enclosure as well as having the underside of the bed insulated too (I am using ceramic fiber for that).

#if ENABLED(THERMAL_PROTECTION_BED)
  #define THERMAL_PROTECTION_BED_PERIOD 60    // Seconds
  #define THERMAL_PROTECTION_BED_HYSTERESIS 2 // Degrees Celsius

  /**
   * As described above, except for the bed (M140/M190/M303).
   */
  #define WATCH_BED_TEMP_PERIOD 90                // Seconds
  #define WATCH_BED_TEMP_INCREASE 1               // Degrees Celsius
#endif

Something like this should work.

Did you select the Mega2560 as the board/CPU in Arduino IDE?

Please see the following link for compilation instructions: https://github.com/davidramiro/Marlin-AI3M/wiki/Customization-&-Compiling

I had it on Ardunio Uno, and how do I save it as a hex file as when I click export complied binary it doesn't give me anywhere to save it just verifies it basically. If this does save it, where does it save it?

[SeventhDread]

And I just have mine in a unused room (usually cold) and just leave it in there I normally print PLA so its good never printed ABS so I have not done anything to the printer no heat insulators or anything

[SeventhDread]

Hi I used this link to export as hex https://www.instructables.com/id/HOW-TO-GET-HEX-FILE-FROM-ARDUINO-/ will this work?

[SeventhDread]

Well the hex file the home completely was off it was breaking and all sorts, how do I get the stock drivers??

[davidramiro]

Did you read the page I linked before? https://github.com/davidramiro/Marlin-AI3M/wiki/Customization-&-Compiling

You have to set the correct motor direction as explained in the Wiki.

how do I save it as a hex file as when I click export complied binary

This is also explained in that page.

how do I get the stock drivers??

This can also be found on the wiki.

Please make sure to read everything thoroughly, especially since you are changing temperature safety settings.

Ahh, I didn't read the part were you have to comment things, thank you, Will let you know if there is any more problems.
