mixing extruder temperature control
Posted: 12 Aug 2020, 15:07
Hi all, I have a mixing extruder with one nozzel heated by 2 x 20watt heaters and three steppers driving RGB fillament can someone please tell me how to heat the nozzel at the start of a print which ever stepper is driving first and maintain the temperature to the end of the print without pausing and waiting at each change of stepper for re setting the temperature because at the moment at each change of colour the printer X and Y stops in one place for probably 30 seconds and plastic is oozing during this time into a blob. If I could set the temperature at the start and maintain it and simply change the stepper from one to the next without pausing I feel that printing would be a lot smoother
