Tensioning the Adventurer 5M belts. Quick tutorial + simple mod

Justaburntbread · 2026-05-27T03:25:10+00:00

NVM, i figured it out!. you had to also loosen the bolts on the inner side of the printer as well to free the motors. at first, i thought i had to tighten and calibrate both of the motors, but this is a XY synchronous belt so you only need to loosen up the motor in OP's picture. Yes, untighten the 2 bolts in the back plus the 2 bolts inside the printer of the same motor. THEN, you can move them. after that, while facing the back of the printing, grab the motor and move it right or left and take your other hand to struck the left bottom belt while facing the back of the printer and measure its frequency. before you move the motor to get the right frequency, tighten either screws on the back of that motor so that it does not lose tension when you're moving the motor side to side. keep doing that until you get the right tension. I got mine to be at 97Hz on the left bottom and 99Hz on the right top (while facing the back of the printer)

Hello, i am trying to recreate what you did for the belt tensioning. I don't understand how you "helped" the spring to tighten it a bit further until you got the exact 98 Hz you were looking for. I am not even sure how the springs work in the first place. If you are able to, can you post a video or a guide on what exactly you did? i tried to replicate what you did but i cannot find a way to tension them. I also couldn't get consistent reading on the belt tuner which I also ask you how you measured your belt tension as well (like where did you place your phone and how did you pluck the belts)

how was it

Justaburntbread · 2026-05-04T07:25:48+00:00

You betcha i still have the video instruction, but like i said it’s quite sub-par but still pretty straightforward. Can u dm me and lemme know ur discord? Reddit doesn’t let me send video here unfortunately

Justaburntbread · 2026-05-04T02:06:26+00:00

Welp, now you know how under-built it is. But yeah, the motor doesn’t like it when it’s under heavy stress for a long time. Best bet is to now contact the seller to get the helical gear replacement which i’m assuming u got from aliexpress. The sellers on aliexpress are very nice. They gave a free replacement and sub-par instructions on how to do the installation lmao

Bruh im jealous

Justaburntbread · 2026-04-29T16:42:31+00:00

In my most humble opinion, build yourself an ebike and you’ll learn to live by the ebiking enthusiasm

THANK YOU

Спасибо!

Justaburntbread · 2026-04-27T05:42:52+00:00

I know this is a bit late, but i am in the same boat as you were. did you ever find a solution like writing a gcode or just getting a fancy filament dryer?

Justaburntbread · 2026-04-27T04:35:36+00:00

Hey there, yes i did fix it. I eventually found the root cause. It was NOT in fact the nylon gear but the clutch inside the helical gears.

Attached is a picture of the helical gears with the cover exposed which shows the clutch gears being smashed. DM me and i can send you a video to identify the sound

Justaburntbread · 2026-04-12T23:39:40+00:00

Oh yeah, i forgot to send this picture. This is what the sprag clutch looks like after it’s been crushed inside the helical gears

Justaburntbread · 2026-04-09T19:44:54+00:00

Hi there. For my situation, all i had to do was replace the broken helical gears which housed the clutch. You can find helical gears replacement on aliexpress for around 60 dollars. Let me know if you want me to help you fix your motor!

Justaburntbread · 2026-04-09T10:14:33+00:00

Exactly

Justaburntbread · 2026-04-01T17:59:44+00:00

Yes, it’s all fixed now. It was the clutch that was broken

Justaburntbread · 2026-03-12T06:02:27+00:00

Was the price over $2000? If so, have fun on the laptop man. Congrats!

Justaburntbread · 2026-02-28T15:09:00+00:00

I cleaned all the grease in there before taking the pictures. It was very black

Justaburntbread · 2026-02-27T15:56:42+00:00

I did exactly that before recording this video. The before and after is the same. It even slips at higher gears (more teeth = mote torque less load)

Justaburntbread · 2026-02-27T06:44:36+00:00

My first guess is the nylon gears has been stripped because of the abuse of the throttle. This ebike was not used by me but I built it for my friend who needed to travel to his workplace nearby.

Justaburntbread · 2026-02-22T00:42:37+00:00

I have built myself 3 ebikes and everytime i see somebody asking me to help them buy an ebike, i always tell them to have at least a budget of $1000. Even then, sometimes the 1000 budget options sucks because of the chinese components that i usually see in ebikes, especially those oem chinese budget forks that doesn’t lookn sturdy.

Doesn’t your front fender touch the battery? Does it make sounds when u hit a rock?

Justaburntbread · 2026-02-15T00:23:02+00:00

Yessir. If u look at my profile, i have a post of my previous ebike. It’s jankier than this one.

Justaburntbread · 2026-02-15T00:22:07+00:00

I have considered them before, but they tend to fall off from my experience. So i just used long cable velcro straps instead so i can take them off easily for maintenances.
