Z Axis Servicing with Standard Aftermarket Lead Screws and Nuts from the Top of Printer
While his design has worked perfectly for me, writing the instructions pointed out how many steps were involed in this design. So the simplier approach to to just have people follow Bambu’s leadscrew instructions, but use the “Adapter for aftermarket nuts” being offered in post 12.
Great modification, the rear z axis is difficult to access
H2D and H2C Extruder Cooling Fan “Quick and Easy Fan Changes”.
Side loading, slide in, slide out hotend fan, tested working.
Completed the Z Axis Serviceability upgrade, here is the before and after “Benchy”, Can you tell which is before and which is after? One is on paper and no is not.
The both look fairly similar to me.
Certainly not a big difference…
Added some pictures to second post.
Looking for people interested in my hotend fan mod, see 4th post
I believe there may be a method to determine the health of your H2 hotend fan.
Measuring the fan RPM and amperes, I have 5 fans and the oldest fan is drawing
0.43a at 9,460 rpm, the other fans are drawing
0.33a at 8,700 rpm
The fan’s rated speed is 8,500 rpm
Hi, just wanted to pop in and say: I congratulate you on the successful mods and I’m really happy to see someone spending the time and effort to make improvements to the H2 series. Of course it’s up to the individual whether the mods are useful to them, but everything contributes to our knowledge and helps move the hobby forward. Thank you!

ADAPTER FOR AFTERMARKET NUTS, kit or premachined.
Available as a kit of three 3d printed jigs, to make the adapter spacers. Or the three required adapter premachined. Each spacer would allow you to use aftermarket brass or POM leadscrew nuts. These adapters and nuts would install exactly the same as Bambu’s Wiki instructs.
Anyone interested please PM me.
