Hey, I am using chimera dual extruder in my printer. I am curious about PID settings in marlin. Should there be different PID for both extruders because there are two hotends. I checked PID autotune in repetier with command: M303 E0 S200 C5, it shows me (Kp: 44.40 Ki: 4.43 Kd: 111.31) values. Then just for curiosity, i give following command for 2nd extruder: M303 E1 S200 C5, but it came different (Kp: 22.62 Ki: 1.42 Kd: 90.06). Both extruders are E3d chimera, so it should be same or slight difference. But there was huge difference. Can anyone tell me, what is solution?? Thanks in advance.

In dual extruder printers, we often face problem related to oozing and this lowers the quality of print leaving the debris on to the walls of the print. There is no inbuilt feature in Cura to avoid this problem. Although there is ooze shield and prime, but it is a waste of too much filament. The clear benefit of this script is near elimination of oozing and depositions on the print. This script moves the print head away from print while changing the tool and wait until it reaches the desired temperature. Also lowers the temperature of another tool. The drawback of this code is too much time wasted in changing temp and waiting. These codes should be insert in Settings > Printer > Manage Printers > Machine Settings. Then Extruder 1 and Extruder 2. Extruder 1 & Extruder 2 start code : M109 S210 //To set the temp of active tool at desired printing temp Extruder 1 & Extruder 2 end code : G0 y0 F4000 // To move the print head away from print M104 S150 //To set the temp of inactive tool at standby temp Also you can add a mechanical wiper made of steel wire or silicone to wipe the nozzles near standby position. (This code is for third party and DIY printers.)

Thanks Nicolinux for replying. I have XY-Z configuration printer with core xy. Two e3d hotends. Bowden extruder.

Hi, I am using cura 2.6.2 and 2.7 in dual extruder. I have a question. I have seen some videos, where whenever nozzles swap (means between nozzles 1 pauses and nozzles 2 starts), print head goes to home position or away from print. Is there any setting or option that I should enable in cura for that? I am frustrated with oozing problem. Thanks in advance.
