[Discontinued] Switch Break-in Machine 4×4 LS (V2)
Archived timeline: Matcha Edition>Sunflower Edition>Banana Edition
The stock motor is faster and hotter than the previous versions, do not increase the input voltage with this one. Because of the summer heat, is is recommended to put this in a well ventilated place, ideally with a fan pointed at it as well.
If the motors break within 1 month of you receiving the unit, I could provide replacements, but I won't be able to help after that time period (I have no way of knowing how long you've been running it for)
1 unit per customer
The rails are prelubricated out of the box, but you might need to reapply from time to time if you run it frequently, follow these instructions to do so: (https://imgur.com/a/xCuyblR)

- Keycaps * 32 with a few spares
- Spare circular buffer pieces * 4
- Wheel wrench
- Extra gear box & motor (no wire presoldered) (new in this version)

In Centered Mode:
- Holds 64 switches in total - 32 on each plate
In Off-Center Mode:
- Holds 32 switches in total - 16 on each plate
- Requires keycaps, switches needs to be broken in on all 4 sides to be effective (by rotating the plate 90 degrees each time)
Use =<75g bottom out switches only when all plate cutouts are filled (32 for off center, 64 for centered). Switches needs to be removed if they are above 75g bottom out.
Compatible Accessories (Can be shipped together):
- Actuation Counter
- USB timer (I would not suggest using the speed controller function, raising the voltage might cause the motors on this to overheat, I will not be responsible for any damages done this way. The timer function is perfectly usable though.
Can be ordered with:
- Plate support fork
- Do not order this with display stands. Orders containing both machines and display stands will be cancelled and you will be charged a fee by shopify.
Off center mode – applies more force to the side of the switch by pressing on the side of the keycap (one side at a time, the user rotates the switch plate to break in the other sides).
- The machine is quite loud, you’d definitely want to place it in another room when running it. I suggest placing a cardboard box over it to slightly block out the sound. Unfortunately I do not have any ways to demonstrate the noise level. But this will be louder than the 3×3
Carbon brush motor – more durable than copper.
Injection molded gear box w/ nylon gears (not made by me obviously).
250+-10%APM with all switches installed – speed changes based on amount of switches & spring weight. There might be variations in speed, it is suggested that the user measure the speed themselves based on what switches are used.
Fully assembled and ready to use out of the box.
Pre-lubricated with grease.
Female USB type c connector with printed housing – soldered by myself, secured with hot glue.
Wire connection to the motor is soldered then secured with hot glue.
Compatible with any 5V 1A USB wall plug/device port/power bank.
- Wheel and USB housing might come in different colors like black/white/blue/etc. All other components will be the same color as pictured.
