P1P upgrade to P1S

Bambu Lab P1 Series
1

Hi all,

I have a few questions regarding the P1P to P1S upgrade. Other than printing ABS and other higher temp filaments I am not sure if there are any fundamental changes between the P1P and P1S

  1. With all of the hardware changes will the P1P firmware be ready to control the additional fans?
  2. Is there an internal temperature sensor in the case to sense the enclosed temperature?
    If no is there away to fit a sensor to the MB of the printer?
  3. Is there firmware available to upgrade the P1P to fully make use of the P1S features
  4. With the P1S upgrade will the P1P always show up as a P1P on the firmware update information?
  5. What would the benefit be of upgrading the bushes on the lead screws to ball bearings as per the P1S?

  1. Yes; All fans are controllable on the Printer and Bambu Studio. The exception is the Chamber Fan is not an option inside Bambu Handy. You can only control % of fan speed via Bambu Handy or Bambu Studio, turning fans on via the machine will only turn them on at 100% speeds.

  2. No and also no; No idea how the P series choses to turn the chamber fan on/off when printing low temp filaments.

  3. No firmware upgrade just have to make sure you add the G Code listed in the upgrade Wiki.

  4. P1P continues to show after the P1S upgrade.

  5. What? Can you show or link me this, that’s a hardware change I have not heard about!

If you have a X1C like the P1S the lead screws where they connect to the top of the support frame have ball bearings - On the P1P there are bushes

My P1P definitely has bearings. It’s 2 months old was there a revision maybe?

Just FYI. Yes xhanber dan will work on the P1P just like the P1S. I have a P1P, i made the arc enclosure for it. I ha e the MC fan working and the chamber fan working.

My P1P now is no different than the P1S i just made my own enclosure for it. I also ha e gcode sqves to run the mc fan and chamber fan.

I still use the P1P profiles and they work fine. I ha e added the gcode inside bambu studio.

The only thing is when i update BBS i ha e to add the code back but thats easy enough i just saved a notepad with the gcode in it and once the BBS update is installed i copy the info in the note pad into BBS and it is good to go again

1: Yes, the fans are perfectly controllable by the mainboard.
2: No, but you can add one withe the xtouch project. (but it is only a indication, no regulator)
3: this is still in the twilight zone…
4: no
5:don’t know
My point of view:
I did the upgrade, mainly for the cosmetics, it is a much nicer printer to look at now. But to be honest, when printing pla, it is a disaster, i have to leave the front door open, otherwise i have lots of james with the ams. Would i do it again? yes, if i want to print ABS, ASA… but for PLA, no, no advantages i see. And, it makes a lot of noise, the aux part fan is noisy, and the chamber fan is crazy loud.
