TRONXY X5SA - Z SYNC

Z - Sync for TRONXY X5SA 300 (adaptable to 400 and 500 and probably X5S) 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 - 5 mm bore 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 screw + 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 ==> to fix the plates to the Z NEMAS. These screws go through the whole stepper block, holding togehter bottomplate + NEMA block + mount plate (see picture) 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 (and the brand new 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 short sample https://www.youtube.com/watch?v=-Z-wwrgvHaQ Don't let the dust on the plexi catch your eye!! What a shame! If you managed to read all this and at this point you think 6 prints means too much printing time, then you should see the "mono-blocks" layout. It's only two pieces, less print time, but you will have to remove the supporting structures and sand the pulley beds, so the pulleys spin easily ---> https://www.thingiverse.com/thing:4897139 TRONXY X5SA Z Axis Synchronizer Z Synchronizer Z Syncro Z Sync
