    Bridgeport Mill Tachometer

    If I understand what it is you are asking, the ram stroke distance is the same going forward and backward, but apparently the ram velocity is faster going backwards on most shapers (I don't about all). So, a good point, only sample distance and time on a forward stroke. Obviously the ram is...

    Hey I had those rotary encoders on my 7X12 as well. The cross slide DRO worked ok but the compound DRO was totally useless. The shaper challenge is that the ram can be set for length of stroke and start of stroke, so kind of hard to set a fixed distance relative to a fixed sensor (if that...

    A DRO scale would be impossible (or should I say very difficult) to mount for the table displacement and that's the measurement where you would want 0.001" or better resolution. The US sensor might work for measuring the RAM velocity, I'll have to think on that one.

    For velocity, the FPM of the ram on my shaper. For distance, the horizontal displacement of the table on my shaper.

    Actually, I pretty much have everything you linked to already, but not to worry there will be some soldering to do before this endeavor is finished:p

    Bridgeport Mill Tachometer

    @whydontu since you're so into this stuff. What sensors would measure velocity and distance down to 0.001"? I can't find either?

    This should work for me. Flexible Jumper Wires - M-F, 100/200mm, 80 Pcs | Active Tech Electronics Distributor (active123.com) These guys seem a little pricy though.

    Electric panel questions.

    Really..... they run copper pipe like that for gas eh. I'm surprised. What diameter is the gas line?

    What do they call the plug type/style that would connect to the 3 pins on this sensor?

    Bridgeport Mill Tachometer

    Thanks for the offer, I may take you up on it. I really don't think I could solder this stuff without messing it up big time. For now I ordered a Nano with pre-soldered pins and a USB cable (couldn't find anything around here that fit) and a pre-assembled 2x16 I2C LCD. If this Tach works out...

    Oh Oh..... This stuff is teeny tiny:oops: I don't think there is a chance in hell of me ever soldering something this small LOL.

    I think the info you are after is in what they call the microcontroller datasheet. ATmega328P pdf, ATmega328P description, ATmega328P datasheets, ATmega328P view ::: ALLDATASHEET :::
