Still wish I'd went with the "Don't buy one" as my things not to do with a Vmax. 2nd most dissappointing hopper I'd ever used, even after sending it back to Valken twice still wouldn't keep up with 12 bps.

For those of you having feed rate issues, see my Valken V-Max Failed thread. That is the explanation of low feed rates, and sometimes no feed rates. After I repaired it with upgraded gears and re-drilled the primary drive gear dowel hole it is absolutely perfect. Feed rate went way up, no more lag. Now in my opinion this was an oversight by Valken. With a properly placed dowel pin those stock gears may be alright. But there is so much play in the pin and hat that the drive gear and idler gear separate when a load is put on them. The reason its feeding slow is because when those gears separate it will skip teeth. After a while it will wear down the teeth and stop feeding all together. If any of you need it, I can offer a rebuilt and improved servo motor.
I love Valken products, and this one has great potential, but they need to recall the servo motor assemblies and replace them with better built, more precise units.
Hey I'm curious as to how you guys managed to get a ramping effect after extended firing strings. I've gone over the circuitry 10 times and can't find how you have increased the voltage to the motor incrementally. There are no capacitors and the timer is wired straight.
I've also spent a few hours trying to figure out the parasitic drain. I think its in the sensor wheel board. With the batteries plugged in and the power off there is 5 volts(logic) feeding to the sensor from the main board. If it were simply straight wired then you would be seeing 18v at all hot terminals since the batteries are wired in series. Reading 5 volts means that the current is being regulated by a series of resistors prior to the sensor. This mean there is heat being transmitted through the resistors which means there is a guaranteed drain on the circuit.
I really do want to know about the ramping though.
Valken, you guys still here? Haven't heard from you in a while and I'd like the answer to that question.
I need a better front hook
