a few beginner questions (bambu p1p user)
Hello
I will be using mk3 from bambu lab P1P
q1 - I bought my mk3 set 2023-05-15 - what firmware version should be already loaded? do i already have mode 3?
q2 - how should I measure the length of the tube - I want to keep the original P1P tube and connect it with the green element to the connector at the back of the housing. Should I count the length from the tip of the hotend head to the entrance of the green mk3 stirrer? Any other way?
q3 - should I program the time interval for the pulses or stay with the one already programmed originally - (I assume it is 0.5s and a multiple)

The filament run out sensor can be disabled and reenabled via a gcode command in the Tool Change GCode. You can use the M412 S0 command to turn filament runout detection off, and then M412 S1 to turn it back on. You can see how I use it in the P1P profile here: https://files.printables.com/media/prints/352274/stls/4273573_8c5caa8e-d78b-4905-bedb-733a7d38924a/3dchameleonbambup1pmode3config.3mf?_gl=1*g5xmxv*_ga*MTgzMjE2OTE2Mi4xNjUzNDM0MTQw*_ga_3HK7B7RT5V*MTY4OTY5MzQ1OS4xNTkuMS4xNjg5NjkzNDY5LjUwLjAuMA..#_ga=2.69897619.266380799.1689455502-1832169162.1653434140 As for not loading far enough or retracting far enough... make sure you have enough tension on the filaments... watch for the filament pausing as it's moving through the tubes. Sometimes, the tubes can get bent and the unit can not push through easily... but there is nothing in the code that would vary the distance it loads or unloads, they're either fixed at 10 and 11 inches for Mode 2, or fixed based on your G4 timing in Mode 3 in the gcode.
Make sure you can easily move the filament freely by hand and that it doesn't bind as you're pushing it... if it's hard for you to push, it's also hard for the 3DChameleon to push, if that makes sense.
