Hello all,
Hoping someone may be able to point in the right direction having come to a bit of a halt with the spindle encoder on a Denford Orac conversion I'm very slowly working through.
I have managed to get GMOCCAPY running with a 7i96 and have got the X & Z axes moving with it. I also have a VFD fitted that but I am controlling the spindle with the VFD panel for the moment.
The next stage is to install an encoder and once the software is displaying the correct spindle RPM I will set the VFD to be controlled from the 7i96 with a PWM board.
The problem I'm having is that I cannot get an RPM indication on the screen. The Encoder is an OMROM E6B2-CWZ6C and is wired to the board as follows;
TB2 pin 7 ENCA = OUTA
TB2 pin 9 GND = 0V (common)
TB2 pin 10 ENCB = OUTB
TB2 pin 12 +5V = 5to24VDC
TB2 pin 13 IDX+ = OUTZ
I've updated the firmware ready to use PWM to control the spindle VFD the same way Rotary SMP did on his minilathe project. The configuration I pulled from the terminal is below;

Can anyone see any obvious error with my wiring or configuration? I am at a loss. For info, the encoder is getting power and appears to be sending back a variable voltage the mesacard. I haven't attempted to edit the INI or HAL files yet as that will be another learning curve. Cheers
