Flsun Super Racer Direct Drive Upgrade!!!

[@SetSunStream]

Hi, I bought the exact same printer with the same direct drive extruder from a guy on facebook. I have a question. I replaced the nozzle yesterday and I noticed that there was a little piece of ptfe stuck above the nozzle (inside). I haven't touched or fixed anything..I just screw the new nozzle in and it worked fine for 2 hours of print already...It should be Ok or I need to replace the ptfe tube with a new one that reaches the new nozzle? (I ask because I'm scared to fuck up everything if the filament starts to come out from above..) Great video and thanks in advance!

What are the m3 insert length like m3x5x4

Why not having chosen a Volcano hotend? It would have been close4 to the factory one.

[@hwbprints7384]

@nesnduma this is the factory hotend, we just replace the heater block

The housing must be printed with ABS, correct?

[@hwbprints7384]

@Slyv3r93 yes this is abs

[@brandonbell4133]

so what about the firmware changes

[@hwbprints7384]

@brandonbell4133 when you switch out to the orbiter you will need to set the voltage to .850 and the steps are 690, klipper you will need to Calc the rotation_distance

So... you are using a Volcano heatblock, not V6....
