Also if you’re having trouble with the tilter, this is not the most efficient solution for you right now, but you should make the ratio you have currently stronger. You have 1:7 right now, with a 100RPM cartridge I assume? That by itself is plenty fast. I’ve seen many teams use this, but it burns the motors very quickly. A compound ratio is something to attempt for your next design. Try both a 15:1 with 100RPM and a 25:1 with 200RPM. The second option is slightly faster. I believe though, you want more accuracy than speed, so try the 15:1 first. These will both provide plenty of torque for you to tilt up 9 cubes or so, and will do so with more than enough speed. The key here though is whether or not it’s built correctly. If the bearings are aligned perfectly or the c channels aren’t aligned, you WILL experience gear slipping. So make sure it’s 100% structurally sound.
