No Power to Motors, connected and talking to micro fine

The instructions worked perfect to get Smoothieboard FW installed, and connected via pronterface. Only problem is, I have supplied 24V to VBB, but no power delivered to Motor Output connectors when trying to move with Pronterface.

Suggestions of what to check next, or potentially a bad component?
Thanks

Hi :slight_smile:

Can we see your config ?

Yes. It is a new board so I am just using the stock sample config from the edge branch.

  1. Robot module configurations : general handling of movement G-codes and slicing into moves

Your config looks good. Is there anything special about your setup ?

No. Just have 1 Motor plugged into M1
USB to computer
and 24V to VBB.
and 2gb micro sd card in slot with config file on it, and flashed FW.
Nothing else is even hooked up.

I can connect to the board with Pronterface and receive “printer is now online”. When I click on the X Motor it does not even enable the motor. The board is not passing the power to the M1 (or any other Mout) connector. Is there somewhere I could probe to determine the board is good.

Also, are the LEDs any help for diagnosis? I only have LED 1, LED3, and LED9 lit. (and they are immediately when applying 5V). When 24V is applied no LED on the board lights up. Is there a 24V status light?

LED10 is the 24 ( VMOT ) status indicator led.
Is it lit up ? ( I suppose not ).
Are you sure you have the polarity right ?

It appears to do everything it seems except move a motor.
I can Set Heater Temp, Set Bed Temp, Check Temp. (obviously I don’t have the HW hooked up, but the SW is responding to the given requests). The SW even responds to the Home X button, but since there is no power on the motor, nothing physically moves.

That’s why I wondered if there is something wrong with the power supply circuit on this board.

Yes, Polarity is correct. I am using a pin Connector, with GND closest to the Mosfet side of the board, then Power.

No, LED10 is not lit. (We’re getting closer :slight_smile: ) I do measure 24V across the outside legs of the Recovery Diode.

I meant to say a 2-pin connector for 24V (Not ATX Configuration).
and I should have said, Correct, LED10 is not lit.

Are you absolutely 100% positive that the polarity is correct ?
If it isn’t, or if you before connected it in reverse then changed to correct, it is possible the diode died. It can sacrifice itself to save the rest of the board.

Yes, I am 100% certain the polarity is correct per the smoothieboard page.
GND is next to the diode/mosfet side of board, and Power is next to the 5V connector as I am using the 2-pin hole, not the ATX configuration. I’ve checked and rechecked that with a meter.

With power off, if I turn the motor shaft, it lights up LED10 while turning.

Are there 24V test points on this board?

You can use the VBB and GND pins on the “external driver” connector ( between the stepper drivers ).

Yep, no power on those points.

Okay, when I measure across the diode with my meter on diode, I get overload both directions. Good suggestion to check it.
Thanks for your help. I’ll post back when I get it replaced with hopefully jubilation.
