G540/Mach3 charge pump fault LED is lit

[will gilmore]

Just starting the electronics for the lathe I am building. (http://cnczone.com/forums/showthread.php?t=92337)

G540, Mach3

G540 fault LED is lit. If I switch charge pump switch to off fault LED goes out and power LED is lit.

I switched the charge pump switch off and hooked up a motor and got it to spin by jogging in Mach3 so I'm assuming (uh oh) that the computer/parallel port is configured correctly.

In Mach3 I went into config >> ports and pins >> output signals and enabled the charge pump on port 1, pin 16. The active low is off (X) but I tried it both ways.

Where do I go from here? Should this be in the Mach3 area instead?

update: I tested from Pin 16 to Pin 25 on the Gecko end of the parallel cable and got 2.1V (http://www.machsupport.com/forum/ind...ic,7563.0.html) I clicked the reset button in Mach3 and tested again and got 0V. Seems like Mach3 and computer are working.

Hi Will.

Have you downloaded the G540 XML file and installed it in mach?

CR.

[will gilmore]

just downloaded it. how do I install it into mach?

[will gilmore]

put 540B.xml into mach folder and opened it with mach. brings me to machmill and problem still persists.

went into bios and parallel port is set to EPP / ECP

this is a motherboard parallel port. is this a problem with my computer?

OK.

Really important. You must go into your BIOS and set the parallel port from STANDARD to EPP. Otherwise nothing except for the motors will work properly.

wow attention from the man.

I don't have a ton of computer experience so this may be something simple I am overlooking.

I start the computer. When I see the HP logo and menu at the bottom I push F10 for "Set up"


I can choose between a bunch of these options.

My options for printer mode are: "EPP+ECP","Output-Only",and "Bi-Directional"

Am I doing something wrong?

Will,

Try the Bi-Directional option in the BIOS.

Tried it. No luck.

Will,

Did you test the cable with a ohm meter to make sure all pins where connected end to end?

Some cables do not have all 25 wires.

[will gilmore]

I had tested pin 16 before and just went through all pins and everything is good.

I also tested the voltage on pin 16 on the gecko end of the cable with charge pump on and off and got 2.1V and 0V

edit: BTW thanks for your time to trouble shoot

Will,

Try configuring the Charge Pump to pin 9

Make sure pin 9 is not one of your step or direction pins for any of the drive axis.
