    It should be the same as other ports, 20khz max, but you need to find out.

    Just to pass along information, according to CNCDrive, direct port inputs are capped at 50KHZ for the UC300ETH.

    So it appears that a 100PPR encoder (up to 10K RPM) should work fine on the UB1 after version 1.6 opto-isolated input since it can read 13.67KHZ. I just bought my board a few weeks ago, what is the current version you were selling then?

    Re: New UC300ETH breakout board.

    I recently upgraded my Romaxx WD1 with a UC300eth controller and a CNC4PC BOB. I?m using Mach3 and the move has been mostly plug and play…mostly. One of my favorite features on the WD1 is the front panel MPG but I haven?t managed to get that running. The control is the original differential out, 25ppr, optical MPG. BOB Inputs are port 1-13 and 15. The signals measure at 4.5V and .1V under input load. I can rotate the knob and watch the BOB LEDs blink through a quadrature cycle. Ditto for the UCC300 plugin monitor. The inputs are defined in Mach3 as MPG. I can jog the axes with keyboard control. The previous Mach3 settings tab shows the MPG1 count at 424. The new C94/UC300eth/Mach3 profile shows 6.15 million. One detent click on the MPG “jogs” 6.15 million steps. Has anyone set up a simple front panel MPG on the UC300eth in Mach3? It looks pretty quick under UCCNC but I?ve got work stacking up.
