  • On the "Feed Spacing" field -- This field is apparently for documentation only as it apparently doesn't affect the behavior of the machine. (at least in the case of the CHMT360P4).

    The Yamaha feeders all (or at least all that I've seen) have a mechanical adjustment mechanism that allows you to move the pneumatic actuator to set the desired feed pitch. The further back the actuator, the longer the throw when activated and thus the more 4mm steps it executes when it retracts.

    The adjustment will be two screws positioned near the pneumatic actuator itself. On smaller feeders, the screws are usually in a recessed slot and pass through a metal cam which is slightly shorter than the slot and which is longer at one end than the other. With the actuator under the slot, there are numbers next to each of the screw holes on each side of the cam. Orient the cam so that the desired number faces towards the screws (is visible when assembled) with the numbers upright while the actuator is below the cam. Then get the screws started through the cam, through the slot, and into the threaded holes on the actuator. Now slide the actuator so that the end of the cam with the desired number buts up against the closest edge of the slot and tighten the screws to hold things in place. (One side of the cam allows for 4 or 8mm spacing. The other side provides 12mm and 16mm spacing respectively).

    On the larger feeders (16mm+ tape width in most cases), there will be two screws with split rings and a kind of rack-gear against rack-gear setup. The teeth on the movable rack will have numbers indicating the feed pitch. Line the desired number up with the indicator on the fixed rack and tighten down the screws.

    If your feed pitch is more than 4mm, don't forget to make sure that you've got the tape lined up with a fresh component in the correct position under the door in the feeder finger before you try to pick components from the feeder or you can get interesting (as in not what you wanted) results, including in extreme cases rather unpleasant carrier tape jams in the exhaust tube on 8mm feeders that involve significant surgery on the feeder to recover.

  • I've posted an open letter to Fluke here: https://www.facebook.com/owendelong

    I encourage others to use social media to try and get this issue in front of Fluke management on a timely basis.

    While I would agree that these meters do have a limited similarity to Fluke's product appearance, the reality is that the look and feel is markedly different. Anyone familiar with Fluke's products would never mistake the light-weight ABS case of the Sparkfun product for a Fluke product. This really does fit into the rounded-corners category of absurd legal actions.

    However, I'm not prepared to boycott Fluke outright until they've had a chance to respond to this specific issue. Fluke didn't actually cause this problem directly or necessarily intentionally. It's more nuanced than that. Fluke complained about some imitation meters. ITC (which I believe is part of DoC) investigated and issued a more general order as a result of that investigation. These meters came close enough to the criteria of the generic order issued that they were caught up in the process by CBP (part of DHS). It's entirely possible that Fluke may or may not be bothered by these particular meters. It's even more likely that Fluke was never aware of this situation or this possible outcome of their other actions. Regardless, my opinion of Fluke and my future purchases of their fine products will definitely be influenced by how they react to this matter.

    I urge restraint and civility. After all, we are much more likely to be taken seriously as a community by Fluke if we give the a civilized chance to respond and plead our case to them in a respectful manner.

No public wish lists :(
