Z SYNC - TRONXY X5SA by VisiTor

Z - Sync for TRONXY X5SA 300 (adaptable to 400 and 500 and probably X5S)
I'm still testing!!!
Items you need to mod your TRONXY X5SA (330 x 330 mm bed):
1 x 2020 - 470 mm max length**. Around 469/468 mm will do fine. Measure the distance between both Z Nemas before ordering/cutting the 2020
2 x pulleys 2GT / 6mm.
I'm actually using these 20 teeth on my NEMAs (see picture):https://www.aliexpress.com/item/32914938878.html
... they work well so far, but after some height adjustments my feeling about the locking screws is some sort of :((
These pulleys use 3 mm locking screws: either you 'kill' the screws or most likely your allen key dies after the first tightening ...
1 x pulley 2GT / 6 mm – 20T, no teeth / 5 mm bore
1 x pulley 2GT / 6 mm – 20T, with teeth / 5 mm bore
1 x 2GT / 6 mm belt *** – 1220 mm closed loop belt
Screws, nuts and washers:
2 x M5 - 60 mm screws (I recommend half thread, so there’s less clearance when mounting the 20T pulleys) + 8 x washers + 2 x M5 locking nuts ==> for block 1 & 2
1 x M5 - 50 mm screws + 2 x M5 nuts + 2 washers ==> for the extension tensioner
6 x wood screws around 20 mm long ==> for top & bottom plates
8 x M4 - 8 mm screws + 8 x washers (max 9 mm external diam.) + 8 x T-nuts 4 mm diam ==> to fasten bottoms & blocks to the 2020 profile
4 x M3 – 50 or 60 mm screws + 4 x M3 locking nuts + 4 washers
2 x Nema 17 mount plates (aluminium 82 mm long with central holes) + 4 x M4 - 6 mm screws + 4 x T-nuts 4 mm diam
For X5SA-400 and X5SA-500 (X5SA-600 ????)
** Longer 2020 profile needed
*** Larger closed loop belt needed. Probably something between 1400 and 1600 mm. Be adviced that I'm guessing, so test with a 2GT belt, cord or whatever you have at hand before ordering the closed loop belt.
NOTE: take care, not to overtightening, when tensioning, even with a 2020 profile acting as a stiffening antitorsion bar.
PRINTING:
I printed ABS with 100% infill.
Scaled up the STLs to 100,7% before generating gcodes.
To glue ABS use acetone. Use a mask to avoid inhaling fumes.
If you go for less infill, think about the tension acting on the pulley shafts and make sure to print at least 4 walls.
After printing, rework the holes carefully. Use 4 and 5 mm drills. Always drill very slowly, especially if you printed PLA.
Here's a 7 sec sample https://www.youtube.com/watch?v=rxuj-Y_QQK8
If you managed to read all this and at this point you think 6 prints means too much printing time, then you should think about the "mono-blocks" layout. It's only two pieces, but you will have to remove the supporting structures, and sand the pulley bed, so the pulleys spin easily.
