How to get solid, non crumbly bars out of TDP-5 pill press : DrugManufacture | Torhoo darknet markets

Hello, I recently bought a TDP 5 and am currently in the process of trying to produce bars. I have been mixing Microcrystalline Cellulose, Magnesium Stearate, and Silicon Dioxide at a ratio of 100:1:1, mixed with a VH-2. However, most of the pills that come out of this have been coming out weak and crumbly, disintegrating under too much pressure. If I adjust the portion of the machine in the upper right that says "big" and "small", to presumably add more force, the bars become too thin and don't properly stick together, and yet they are still somewhat crumbly and not firm.
Does anyone have a step by step guide on bar pressing with the TDP-5, and how to get consistent, firm bars? Thank you.
