PDMX 126 with AM822 drivers and relays.

Take 2.

Still awaiting the AC power relay, and the 882 USB to Rj cord. Does anyone know if this is an easy DIY to make up the USB to rJ connection ?

Was thinking of getting the 2 cords, splicing in the middle and connecting.

You need both a USB to serial converter, which is more than just a cable, and requires a driver, and the serial to RJ-11 cable. Here's the pinout for the RJ-11 cable.


I just ordered one from the US Leadshine distributor.

More progress,

Control box almost complete now with off latching e-stop and reset switch

Black is AC power in
White is relay controlled AC power out for Spindle / H20 pump / Chip extractor
Small black is always on DC power for the UC400 controller + feed to the PDMX BoB


Internals....
68V AC->DC converter on the left, with 12VDC supply off that holding a 40A/250AC Solid State relay at the back closed.

5x882's in the middle, ( still awaiting the tuning cable to arrive )

PMDX 126 on the right.

Still to come - install + connect the UC400ETH, secondary E-stop circuit to the E-stop button from PDMX, limit switch wires & stepper motor connectors on case, cooling fan
