Problem with Auto Trickler V4

[Jack Sapp]

Starting to have problems with my V4. Its overthrowing the desired drop by as little as .002 to .100 grains almost 50% of the time. I'm dropping Varget. I have leveled, Calibrated, and nothing seems to help. Looking for suggestions! TKS, Capt. Jack

Get ahold of Adam. @adamjmac

Unplug the scale and leave it for about 10 minutes or so before powering back up. This resets the electronics. It fixed mine doing the same thing. You might also back off a half grain or so on your initial drop and adjust the trickler speed as needed.

At this time of year, static buildup 'might' play a role too.
Wipe your system down with a NEW dryer sheet and see if it helps.

Hope this is useful,

I forgot about that for sure. Dryer sheets are your friend

the new powder throwing system makes them tingle in its boots, that is what is causing the variance

It helps NOT having it level
high in the front helps with the over throws.

I have been loading Varget the last few days and have noticed that when several grains are clumped together just as it is coming to weight.

Exactly. You can also shim the top to experiment with front or rear tilt leaving the scale leveled.

I think it is important to clarify what the "calibration" step really means on an AT4. Most importantly, the "calibration" step does NOT change any machine settings. It merely measures the powder dispensing flow rate. I think "Assessment" would be a more accurate description. Adam describes the process here.

Once you have the machine delivering close to the recommended 0.2 gn/s spec, then you can play with the speeds and cut over points to reduce the overall dispensing time. HTH.

2 thousandths of a grain?

 

[Jefferson]

he probably means Point 2 one hundredths of a grain

 

[rijndael]

Which, for many extruded powders, is about 1 kernel.

Thanks that helped!

Yes

Make sure the powder dispensing mechanism that sits on the 3 rubber bumpers/grommets are where they should be, and the one on the rear as well. And every things is nice and snug on top. I notice they tend to move around affectioning the angle of dangle on the powder tubes, in relationship to gravity. Texas heat.

This works for me too.

I've had the rear of the housing be off-kilter on the pad, which causes a "nose-down" orientation. Does weird things to the consistency. Make sure you're roughly centered on all 3 pads.

If the scale is not level it will affect powder measureing accuracy, thats been my experience.
