Parallel Port breakout boards, motherboards, and dedicated accessories / PDMX 126 Rev A to Rev C upgrade
« on: February 20, 2022, 06:35:58 AM »
Good Day all
I have fitted the new rev 126 board into the machine and fired it up but am having a few issues.
The machine powers up along with pc but when I go to press reset on mach 3 nothing happens.
In fault finding I have chased all wiring into the board to confirm no issues and removed the estop circuit and put the loop supplied back in to make sure that the estop loop isn't at fault.
Dip switches are the same from the rev A to new Rev C.
The pin out in the old board which I have wired back up to is..
J7 PCGND SS relay gnd
J7 OE SS Relay +
J8 AC Live
J8 AC Neutral
J10 Com Common to 107 board
J10 N/O Relay
J10 N/C Relay
J11 E Limit Switches X Y Z
J12 11 Relay
Gnd -24v rail
12 Z height homing switch
Gnd -24v rail
13 4 Height homing switch
Gnd -24v rail
15 Z Probe
Gnd Chassis Earth
J13 Estop
Gnd
Estop light is red on 126 from power up and wont go off, even whilst I have shorted the estop to gnd with a wire to bypass to test.
Prior to this I missed to check a jumper on the Estop on the new board that was default, this would enable all drives etc before mach 3 would enable. Now changed that to the M hold and drives do not engage but nor will mach 3.
If anyone could help shed some light on this for me I would be grateful.
Kingest Regards Tom
