    I prototype new design parts with a 3D printer first to check assembly and fit to existing parts before machining. It saves a lot of time and material when looking to see if parts can be assembled...

    To go from a TTL encoder to a differential receiver you need a AM26LS31C Quadruple Differential Line Driver. I have the Renco RM21 PDF that gives the wiring but it is too large to attach.

    The difference is obvious, a TTL encoder has just A,B,I outputs, a differential has A, /A, B, /B, I, /I.

    Here is a listing of the 17 pin and 14 pin connections. No need for the Motif P9 connections. Read as follows for the encoder:

    Thanks but this is way older than a Coldfire, a '91. I have rebuilt a few boards, such as the servo and power monitor, added a push-pull chip to the receiver for a 4th axis and added more memory so I...

    Alarm #112 Interrupt fault

    Anyone ever have this? The manual just says "Call your dealer, electronics fault". Right, they probably want to sell me a computer that costs four times what the machine is worth.

    I do not know if a '97 differs from a '96 but the manual says the encoder Z channel signal must occur between 1/8 and 7/8 revolution from the HOME switch release or a 165/166/167/168 error occurs....

    I found putting carnuba wax on the tool holder taper works well to keep them from sticking in the spindle.
    You can try selling them but BT40 are far less common here than CAT40 so there is not much...

    My VF-1 has BT40. I have 4 new and 1 slightly used CAT40 forks that I would be happy to trade for as many BT40 forks that you are willing to let go of.
    No need to change studs, that has no effect on...
