Cartridge Filler Q&A:
How to set the temperature and select syringe sizes for different viscosities/volumes?
The temperature 70 Celsius, you need to heat your oil container in boiling water first before sucking into the machine the oil needs to be almost water like consistency to work properly.
The needle size depends on the amount you must suck up. The consistency doesn't matter as it will always be like liquid to suck it up .the smaller needle works good for getting the last amount out of the jar easily and the mediums and large are good for large amounts I would say the 15 g needle is the best in my opinion.
How to make sure it's accurate if you need to fill by weight?
Regarding your final question about the accuracy when needing to fill for weight.

Although vape cartridges only come in two standard sizes 0.5 and 1 ml which are half gram and 1 g.
