  • Does anyone else hate their Intellidropper as much as I hate mine?

    1. It’s a pain in the ass to clean up
    2. The scale constantly floats. If I leave it sitting, it will be off a grain or more in 10 minutes.
    3. I have to zero after almost every drop
    4. It overthrows/underthrows constantly

    I’ve followed all the wisdom. Calibrate. Powder calibrate. Wipe with a dryer sheet. Make sure it’s level. Use the cover to keep moving air off the scale.. blah blah blah and I still can’t stand using it.

    From what I’ve gathered on the web and personal experience: they cheaped on the power supply and it shows with electrical interference. I was able to turn off the lights on the same breaker and make it work right. Left on for a few days and it still drifted .2gr

    Other options I’ve heard are getting a portable power supply with AC adaptor so it’s in its own circuit.

    That said, maybe you got one missed by cheap QC.

    I have a Chargemaster 1500 and Lite, not an Intellidropper, but hopefully this should apply. These thoughts are in no particular order.

    Load cells in general hate fluorescent lighting because of the EMF. I was able to get my Chargemasters to calm down significantly by replacing every bulb in the room with LED conversions. Pain in the ass (and in the case of the T5 tube fixture over my bench, expensive), but it was worth it. The floating scale says this might be a culprit. CFL bulbs were among the worst things to get foisted upon us, from both an environmental standpoint (there’s mercury in the tube) and from an electrical interference standpoint.

    You might be able to build a rudimentary Faraday cage around the unit for at least testing purposes.

    Look into the McDonald’s straw hack for the Chargemaster. They also make tips that go over the end and reduce the diameter of the hole at the end of the drop tube. Those reduce the overthrow incidences significantly. I also have a Area 419 aluminum pan coming for the CM 1500. The extra weight is supposed to help deal with drift.

    Underthrow sounds like it’s related to the floating scale issue. I found with the cheap MTM scales I also had to turn off the ceiling fan. Less so with the CM’s.

    The biggest thing that I did that made a difference was set up a spot where the powder throws could live permanently, but I don’t know what your space situation looks like.

    You can also try running about a pound of powdered graphite through it, like you would if you were breaking in a powder measure. My CM 1500 was purchased used, and the previous owner did that, but I never did it with the Lite that I bought new.i’m not sure how much that would help overall, but it would cut down on the static for sure.

    There’s also a guy who rebuilds used Chargemasters when he buys them on Ebay. He heats up each of the solder joints and adds a little fresh solder to repair any cold joints. The end result is a much more reliable machine. Depending on your skill level and comfort with a soldering iron you could also theoretically take it apart and replace the load cell with something more reliable. (I once tried to build my own auto trickler – it didn’t go well, not because the hardware didn’t work, but because I’m a terrible programmer).

    I’ve seen people mention similar issues with this power supply. I don’t have one, but I can’t help but think using a decent ATX power supply would fix the issue. Maybe something to look into

    There are threads on how to clean up the power interference.

    So I’m on my 2nd intellidropper and you’re spot on with the frustration. I still have my old one, but found it was weighing at 1.1 grains under on every throw. So a 41.5 would actually be 42.5. It was consistent but I wouldn’t trust that.
    I’ve found with my second one to keep it on. I replaced the power supply with a battery, but that didn’t help with drift or electric current. I then used the power cable that came with the battery pack. This actually seemed to help a lot.
    Additionally I try to avoid it during peak work hours. I found that if I throw early on a weekend or late night on a weekday I get more constant throws. Maybe this is the city’s power grid.
    On top of keeping it on 24/7 I recalibrate in grams with the check weights every session and probably every 30min. I weigh every charge on a Ohaus 505 I bought after each throw. It seems that there’s now about a .05-.1 grain difference. Generally throwing .1 under and adding 2-3 pieces of powder gets me spot on.
    It’s not a perfect system, but it is working well enough for single digi SDs and low ES. Also I only really load .308 and 6.5 for PRS work.
    I understand the frustration and was set on buying an AD120, but think my system is working well now. Next purchase is def a giaurd trimmer because trimming on my Lee is getting old and time consuming.

    Use your old car battery as power supply. Recharge battery one time per month. Forgon about power supply issues.
    Be careful, if your power input for appliance not a 12v, you need use low noise dc/dc converter.
    (Usually more condensators on pcb board means less noise).

    I went from a cheap digital scale to an A&D because of drift. Part of it is power supply, part of it is scale construction. Some of them are simply just crap inside. My cheapo didn’t drift 30 grains that I noticed but after it was turned on it would need a long time to settle, like a day or more. If I plugged it in and started using it immediately it wouldn’t hold zero for more than a few minutes.
