Aluminium Profile Type Router - Initial questions

[AndyUK]

700 x 500 x 250mm steel cabinet arrived today from TLC. Very solid and heavy @ 20kg. - hopefully everything will fit in based on previous builds on here! I see Andy had 800x600 which had a little space spare.

Yeah you'll be fine :) 800x600x300 was overkill. I have no idea how Joe filled 800x800x300.

I'm trying to take each component in turn and map out the connections - first the driver to AXXB-E. Except for ALM I can't figure out which other terminals need to be connected if at all ? For example ENA+, Pend, and the Encoder E* ones.
AXXB manual refers to just Step and Dir.

Good plan. Generally speakings, Step and Dir are the two required ones.

Enable turns the drive output on or off to prevent the motor turning without killing power to the drive, usually when left disconnected the motor is just enabled by default.

Alarm should output a fault signal to the AXXB if something goes wrong. Best to have it connected somehow if you can, but there are a lot of options about exactly how you wire it up. E.g. it could estop the system on fault, or just tell the AXXB to pause.

Pend appears to be 'positioning completion signal', encoder and the motor phases should be the wires from your motor.
