Maximum temperature #12

Closed locki8383 closed 3 years ago

Hello,

due to security reasons is it possible to implement not only the minimum but as well the maximum temperature for shutdown. Just in case of a meltdown of transistors or something else.

Thanks in advance

Locki

Hi Locki,

This is a good idea. I will check the documentation of OctoPrint to know the offered possibilities.

Ranney1 commented 3 years ago

Yeah, that would be great! And, if possible, maybe it is an option to read the GCODE and if an M112 is send or if the connection is lost that the power can be turned off? Thanks for the great plugin!

Salamafet commented 3 years ago

@Ranney1 can you create a new issue for the GCODE support ? And please add more details. I'm not comfortable with GCODE command.

I adding connection lost action in my todo list.

Ranney1 commented 3 years ago

@Salamafet Of course, i will add a new 'issue'. Thanks for your time for the plugin!

And about the GCODE support, if a user want to terminate the printer instantly, they can also send the GCODE: 'M112' to the printer. It will turn itself off directly. So my idea was:

I think that this can make 3D printing a little bit safer!

Currently I'm working on the security options. What is the common critical temperature for a nozzle and a bed?

Ranney1 commented 3 years ago

Hi,

Thanks for all your work!! The max temp of the nozzle is for every printer/setup different. For bowden tube machines the max temp that the bowden tube can handle for long time is around 225 celcius. A little bit warmer (230-245) is possible but this will impact the life of de bowden tube. For direct drives it is what the material of the hotend can handle (examples: https://e3d-online.dozuki.com/Wiki/Maximum_temperature_for_the_Chimer). For me, as 'home user' I don't want 'to see a temp higher than 230 celcius. As a reference, I think that higher than 260 is not for the 'normal' user. (Common materials: https://m.all3dp.com/2/the-best-printing-temperature-for-different-filaments)

Can you make the max temp configurable?

Ranney1 commented 3 years ago

Ø, sorry, I didn't answer your 2nd question. I think that it is the same for the heated bed. My printer cannot handle a higher temp as 110 celcius for the bed. But.. I do not use materials that needs a higher temp than 65 celcius. So, if my bed will get a temp of 70 celcius, there is absolutely something wrong..

Salamafet commented 3 years ago

Ok thanks

250°C for the nozzle and 80°C for the bed seems to be good as default security shutdown. In the worst cases of a user use higher temperature, the printer will shutdown before print begins (except if the temperature is modified by the gcode along the way).

New release with the maximum temperature option :) Please reopen this thread if you have an issue with this release.

Perfect!!! Thanks for modifiing this plugin. This is exactly what every 3D printer user should use to avoid bad surprises. Now it feels a bit safer to use my printer. Thank you very much.
