Hello
Help me please. I have voron trident like printer. My 1st custom assembly.
CONFIGURATION
• 4040 (v-slot) and 2040 (t-slot) frame with corners and corner outer plates;
• RDBB 500mm rails (12mm on X axis);
• powge pulleys and idlers, 6mm gates belts (tensioned at about115-120 Hz), fushi bearings;
• 8 mm aluminum print bed 355х355 + 4 mm glass mirror + 220 v heater;
• 8 mm lead screws with 4 lead and antiwobbling solution like wobbleX + couplers sit on thrust bearings;
• Bigtreetech Octopus Pro STM32F429 (CAN bridge mode) + tmc2209 (StealthChop is turned off) + Bigtreetech EBB36 printhead board;
• cloudray 17cs04a-170e motors with 0.73 A run current in Klipper config;
• Meanwell 350 24 V;
• Klicky probe;
• dragon burner printhead with sherpa mini extruder and LDO 36STH20 motor;
• Volcano aluminum hot end with short e3d v6 heatsink (dragon mount). Trianglelab;
• holder for cable [www.printables.com] ;
• Mobil grease Mobilux EP2 for rails and screws;
• 2 800 acceleration in klipper.

PROBLEM
I have problem – random ripple on Y axis. In vase or regular print mode the ripple changes (size, angle, direction, depth) on different heights, sides and places of print bed. I printed 20 small objects (boxes) in serial mode and all objects had different ripple or some didn’t have it.
At speeds about 100 mm/s the Н axis often becomes smooth without ripples even from belts like on the X axis. But at this speed the corners and details are already slightly smoothed out.
I need to print some plastic at low speed, so you need to fix the problem.
On Orca Slicer VFA test from 30 to 140 mm/s (+5) the ripple changes even at the same speed segment.
The ripples seem to be more pronounced when the head moves backward on the Y axis.
At the moment, the printer has worked for about 400 hours. Over time, the defect became more noticeable.

But with every print and on every object the ripples are different. Ripples can only occur within a certain band in height or at intervals in height. Sometimes the ripples on 1 wall change to the opposite angle several times.

I saw some amount of such ripple on some prints of users with other vorons with stock heavy print head.
I'VE ALREADY DONE
1. Changed printed Sherpa mini extruder to Fysetc CNC version with helical gears;
![1_03_f69c49b4-70c6-4365-909c-02ee529727e7_480x480.jpg]( "1_03_f69c49b4-70c6-4365-909c-02ee529727e7_480x480.jpg")
2. Changed hot end heatsink to Trianglelab. It has better heat break fixation;
3. Changed printhead fans to GDStime with ball bearings;
4. Changed tooth pulleys (they eat belts on Voron) to double flanged fushi bearings ;
5. Changed printhead to more stable 8th version of Dragon Burner with custom very strong carriage. My custom desing;
6. Installed custom printhead board mount that is held by 4 screws to the carriage and extruder;
7. Installed 1mm M5 shims between all pulleys made from flanged fushi bearings. Voron eats belts in these places;
8. Changed M5x40 screws, M5 nuts and m3x8 screws (MGN12 mount) to titanium version;
9. Reduced the number of bolts and nuts for the X rails, using fastenings through 2 holes;
10. Changed cloudray 17cs04a-170e motors to 60 mm version (17CS07A-180E). And changed back;
11. Disassembled and cleaned X rails.

It did not help. Or I don't see any noticeable changes.
Input shaping results (only the hot end fan is on):

WHAT I'M GOING TO DO NEXT
I’ve already received parts
1. Change all printed parts in the XY gantry and printhead from ABS+ to ABS+ with 10% glass fiber;
2. Decoupler mod (without rubber motor mounts) https://www.printables.com/model/430168-voron-trident-stepper-decoupler
3. Active cooling and heatsinks for XY motors. They are only 50*;
4. Change XY motor drivers from tmc2209 to tmc2240;
5. Fix top parts of 2 M5 XY screws with pulleys which don’t use nuts;
6. Perhaps I'll replace the cable holder with a short flexible chain.
The carriage on the rail on the X-axis has a slight play if you apply force. It's very difficult for me to capture it on camera. I don't know if it should be like this. When removing and disassembling the rails by hand, no play is felt.
HIWIN rail cost a lot (like used ender 3 on ebay for 1 mgn12 500 mm). It’s hard times in Ukraine and I’m not sure that Ukrainian sellers sell original HIWIN. But I don't want to play the game of matching balls for Chinese rails.
In the future (to assemble the IDEX) I will buy expensive rails with 2 carriages (it is difficult to find 2 identical carriages for Chinese rails). But I wouldn't want to spend money on it now.
P.S. 1 man solved it by replacing rails https://www.facebook.com/groups/voroncorexy/permalink/1800631243698767/
After replacing the printed parts I will try to loosen the Y-axis rails, move the X-axis and fix the rails again.
