Select the Semitec 104-GT2 (E3D hot ends) which will give you the followingħ. Moving onto the heaters section, set the temperature limit to 285☌ and the PWM limit to 100%. The higher this figure the larger the risk of overheating and damaging the stepper driver.ĭuet boards make use of a more compact soldered stepper driver design which unfortunately means if you blow up a stepper driver you will need to replace the entire board.Ħ. 800mA is a good starting point but if you are noticing a lot of skipped steps and motor stalling you can increase this value to 1000mA. With regards to motor current, you want to aim to use the smallest figure that works for your use case. Steps per mm on the Extruder motor is what you will need to change for the Hemera you will need to change the value from whatever it currently is to 409 assuming a micro-stepping value of x16. These values will change depending on the type of motion system being used and the rigidity and quality of parts being used. Next is where you configure the motor behavior, typically we don't offer any suggestion for axis settings here and recommend finding out this information directly from your manufacturer or finding out the values used by other members of the community who share the same printer. The Z probe options depend on the method of bed levelling being used we recommend visiting the Duet documentation for more information about what you should choose.įor more information regarding the differences between temperature sensors click here.ĥ. And if using multiple HotEnds do the same for e1temp etc. On the same page you will see the Heaters tab, This is where you select the type of temperature sensor being used for the HotEnd/s and bed.Īs standard, all E3D HotEnds ship with a thermistor so make sure to select thermistor for the e0temp. However, if you wish to use more fan ie a dual part cooling fan setup or a stepper driver cooling fan you will need to configure the fan pins to the connections being made - for more information visit the Duet3D documentation.Ĥ. Equally depending on the type of motion system you will be using this will also appear different.įan mapping is fairly straight forward typically there are two fans used in a setup 1 for cooling the heatsink of the HotEnd and one for cooling the part as it's being printed. Next are some more specific settings where you add the number of drives (motors) being used for the majority of use cases this will involve only one E0 drive, if however, you are using an Idex or Tool changing system then this would increase as per the number of toolheads being used. None of these settings are HotEnd or Extruder specific and will rely on you taking measurements of your specific setup or finding out the dimensions from your printer manufacturer.ģ. In the first section you set the basic parameter of your machine, including the board you are using, the name you want your printer to be known as, the min and max values of the motion system and where the Axis should home to. Unless your printer is one of the preconfigured options you will have to select custom or insert an existing configuration.Ģ. For full details on how to set up your board please visit Duet3D's documentation pageġ. This is not an exhaustive guide on how to set up a Duet 3D board, it covers the specific relating to the Hemera HotEnd and Extruder combination. For the RepRap online configuration tool click here
