opinion about Twotrees Sapphire plus 1.1 and tronxy x5sa pro

[shakle]

I have to print big lecter. I think to go with tronxy X5SA Pro.. the largest size of print volume makes me lean for it. What are the upgrades to do?

Depends on what you end up with.

My X5SA Pro came with a busted card reader, so my upgrade path was a lot more urgent than I'd intended.

I did these changes:
Critical changes (so I could get the job done)
• Replaced print surface with magnet/PEI flex sheet (bolted down so no springs)
• Replaced board with SKR 1.4Turbo + 2209s + TFT 35
• Replaced clone bowden titan extruder with direct drive E3D titan + V6
• Marlin firmware running sensorless, UBL, individual Z, and linear advance.

Long term reliability and QOL changes:
• Mic 6 bed + 500w keenovo heater + graviflex magnetic base (still to do)
• Meanwell 600W power supply (still to do)
• Gates belts
• Toothed idlers and reinforced idler mounts
