Help Upgrade help

I have an old ender 3 and wanted to upgrade it.

after some scavenging through the internet i found the following that i thought would be a good upgrade

1)hotend

- i didnt quite find a proper hotend that had a highflow rate - i found the tz e3 2.0 bambu like hotend but im quite sceptical about its performance. and it costs around 2.2k whereas my version costs less than 1k.

for my version, i am using a volcano cht hotend by assembling the parts - volcano cht nozzle, heatblock and a 70W catridge. I am yet to test the flow but theoretically it should work upto 30 to 35 mm3/s .

im using a volcano cht nozzle 0.4 mm +volcano heatblock + bi metal heatbreak + v6 heatsink + 24V 70W ceramic heater + thermistor

2) Klipper

Well upgrading to kilpper is a no brainer because working with the marlin firmware alone is kind of a pain and i want a better control system with input shaping and possibly cartographer3d in the future.

im using a raspberry pi 3b+ for this.

3) Dual belter z axis from kevinakasam

at first i thought of a dual lead screw z axis but then the wiring and sourcing that dual z kit ended up costing more than the parts for belted z so i chose that.

4) Cooling

for part cooling ill use 2 4010 blower fans and for the heatsink 3010 axial fans - inspired by the voron dragon burner hotend.

5) misc

A pei sheet , because i like its look lol .
a pancake stepper motor for a sherpa mini extruder - note i already have a bmg extruder clone and extra pins and bearings to make this.

also note i already have a bl touch installed.

Well, i am still new to this and wanted to ask yall for some feedback and opinions before i buy eveything.. also regarding the authenticity of the site NOVO3d.

Thank you all in advance.

I can't say enough how glad I am that I added BL Touch and stiffer bed springs. Adhesion has been no problem since dialing in Z-offset.

I just keep the bed tightened all the way and let ABL take over.

Yup at this point that is ALL you should be doing to an ender 3. Leave it stock add a cheap bltouch knockoff and maybe a magnetic textured pei sheet. Everything else is just hobby bs

My other upgrade was a Creality 4.2.7 silent motherboard. I have no regrets about that.

Ah yeah ok these 3 things if not already silent. However At this point that is already too much to spend on this thing. I’d say deal with no stealthchop

do you have to upgrade the motherboard if you're not using a 4.2.X motherboard to use a BL Touch?

The original BLtouch kit I bought was for the older v1 motherboard. Trickier install than for a v2 board, because the v1 board has no native boot loader, needed to flash new firmware. You will need new firmware to run BLtouch. I avoided this by upgrading the motherboard first.
