5 Hotends



  • I have a customer who likes to drive 5 hotends together so synchronously.

    This means that all hotends should be held by a command to maintain a temperament of, for example, 240 degrees and each of the hotends is controlled for itself with the same set temperature.
    this with 5 PT100 sensors.

    How can I do this?

    then it is possible for each extruder itself to mount a laser sensor and if one is not in operation to disable?

    The extruders are controlled to the 5 hotends and are all controlled with the same inpuls.

    is this possible?

    You could configure your 5 hot ends as a single tool with 5 heaters. Configure your slicer to use G10 to set all the temperatures, not M104 not M109. Caveat: in firmware 2.03 there is a limit of 4 heaters per tool, but I can increase this if I know that you need more.

    Also configure the tool to have 5 extruders, and set the mix ratio to 1:1:1:1:1.

    Currently the firmware doesn't support disabling an extruder and continuing the print if the filament monitor reports an error.

    Off topic as far as the OP is concerned but I could foresee a need to have up to 8 heaters fpr a single tool. That's extreme I know but I have my reasons why that might be necessary. Up to 6 heaters is more likely but 8 could be a possibility. I have lots of work to do before I'll know for sure so no hurry.



  • Thanks for your Feedback
    Please can you make the update on the Firmware up to 5 Hotends.

    I will make the 5x Hotends, the 5x PT 100 and 5x Laser Sensor us synonymous.
    So that I can print in the same time 5x the same object.
    This case give me some open questions.

    When I will use only 2 Hotend, PT 100 and Laser Sensor what will be happen with the other three? Can I Setup them on the Display with a makro?

    Can I setup with G10 P1 R20 S240 all five hotends at the same time? Or I have to make this for every Hotend separately?
    Have you an idea how can I setup G10 in simplify 3D?
    It`s possible to control the room heating on the Display 7?

    You can set up different tools to use different numbers of hot ends, for example tools that use 1, 2, 3, 4 and 5 of them. So the ones you are not using won't get heated.

    Can I setup with G10 P1 R20 S240 all five hotends at the same time? Or I have to make this for every Hotend separately?

    The syntax is G10 P1 R20:20:20:20:20 S240:240:240:240:240. But I've just checked the code, and if you want all the heaters to have the same temperatures, you can use M104 and/or M109 instead of g10.

    It`s possible to control the room heating on the Display 7?

    Currently the chamber temperature is not shown on the LCD display, but this is scheduled to be added.

    I have increased both MaxHeatersPerTool and MaxExtrudersPerTool to 8.



  • Hello

    I have now played the 2.03beta2 firmware on it and always get the error that T5 is too long. Then 5 heaters and 5 extruders should be controlled.

    do I have to adjust a little more?

    I suggest you use 2.02 firmware for now because that didn't have a limit on heaters or drives per tool. The limit in 2.03beta3 will be 8 of each.



  • but I need the laser sensors on the extruder then I have to take the beta, this is how it works.

    Each laser is connected to an extruder and should only be active when selecting a tool.
