Thank you for adjusting. Is it ok like this? And is it ready? |

| 1. Place your trackers in a fridge or freezer for a period of time to cool them down to below 15°C. If you're unsure about the temperature of your trackers, you can check it in the SlimeVR Server when the tracker is turned on. | ||
| 1. Turn on your trackers and gradually heat them, calibration will automatically begin if the temperature is below 15°C. | ||
| - You can use something like a 3D printer bed or a heat gun, but be careful not to overheat your battery or melt your case. | ||
| - It is important to not rush this. Temperature calibration should take at least 15 minutes, otherwise you risk having a partial calibration, which can lead to increased drift. | ||
| 1. The calibration will be complete and automatically saved once the IMU reaches 45°C. | ||

| 1. Take the tracker out and put it on a stable surface like a table. | |
| - Open the SlimeVR app -> Turn on developer mode -> One the home tab at the bottom-right, toggle "More info" to see all details about your Slime and it's temperature. |
| - Turn it on and let it sit until it reaches operating temperatures naturally; Don't use a hairdryer yet! When you put your tracker closer to your computer you can reach a higher temperature quicker. | ||
| 1. Wait until your tracker's temperature levels out. Warm it up with your hairdryer to around 43°C, do not reach 45°C yet. | ||
| 1. Let it cool down naturally to operating temperature again. | ||
| 1. 30 degrees? Airdry it to 46 degrees to squeeze out the last points for your TCAL and let it cool down. |

| 1. Once around 30°C, use the hairdryer to get it to around 46°C to finish measuring the last points for your TCAL, then let it cool down. |
