None of the motor will move!

Hi,
None of the motor will move, but the bed and nozzel heater works ok, and the web interface is also ok.
I updated my config.g from the web interface, because I had to change one of the M557 cordinates. After that I can't home anything, or manuel move a motor.
What happend.
I run firmaware version : 1.00m dc-42 and web interface 1.02

Could you give more details. Are you saying that the motors worked OK before you changed the config file, or is it the case that they have never worked?

In addition, when you say you cannot manually move the motors, is that when the Ormerod is switched off, immediately after powerup or only after you have sent a command?

Hi Guys

Had similar issue, just to find out I had to run the HomeAll command from the webInterface first.
Not sure if this is by design, but that solved my issues

If you run M503, is the config.g file echoed correctly? Perhaps it is not finding any M906 commands to process in config.g, so the motor currents are all zero.

I uploaded the old config.g file again, and it's still same problem.

The printer run before I changed the config file, I also uploaded a new print file! Can this upload overwrite anything? I use the upload from the webpage, the file size is 2.4 Mbyte.
If I press the Home All or any other Home buttons, nothing happens.
I can move the x,y,z by the hand, but not manual from the web interface.

I measured the supply, and when the printer is idle, the supply is 12.5 V.

Hi,
Are there some who have a good suggestion, to find out whether it is a HW problem or a SW problem?
Some diagnostic commands.
Enable a debug messages or ...

Are you quite certain that the bed and the hot end heat up? Have you checked that the 12V input screw terminals are tight?

It might be worth trying different firmware, e.g. my 1.00o release, zombiepantlol's latest release, or RRP 0.78c - just in case there is an issue in that firmware release that I am not aware of.

I have now reinstalled 1.00m and overwrited all Web files, and files in the sys folder. (This worked for me, a week ago)

Both the bed and hot end warms up fine.
But if I press a Home button, or move the head 0.1/1/10/100 (by the buttons in the web interface) something strange happens. The WebInterface stop update, and 15 sec. after both hot end, and bed stop warm up. The red LED (bed) and the Yellow Led (Hot end) turn off. and the web interface stop responding on any commands!

That sounds to me that the firmware is crashing and the software watchdog is resetting the printer. Please do the following:

1. After this has happened, reconnect the web interface or Pronterface. Then run M122 and see what the last reset reason and software reset code are.

2. Try version 1.00o to see if it does the same thing.

It sounds like trying to move a stepper is crashing the Duet. That could be caused by a short somewhere, or maybe digital noise. It is unlikely to be caused by the 12V not being able to supply enough current to power a normal stepper load because the stepper load is small compared to the bed heater load, which you say the 12V is able to cope with. Could you try moving just one axis at a time and see whether the issue occurs after trying to move any of the 4 stepper motors, or whether only some motors generate the fault. This will help determine where the fault may be. Also if not already tried, try moving the X, Y or Z motors with both heaters turned off.

In addition, unplug the motors (always power off the Duet before plugging or unplugging a motor), and try moving an axis via the web. Obviously there will be no movement with the motors unplugged, but see whether it still crashes the Duet when you do this.

Carefully check that all your wiring is correct and you have not inadvertently connected the steppers to the wrong sets of pins (e.g. displaced by one pin etc.)

Have you tried moving a motor via the web interface with the USB completely disconnected? If not, do so in order to eliminate possible ground loops/spikes. Also ensure that your PSU is plugged into its own wall socket (as opposed to an extension lead or adapter that is shared with other devices).

I could not run M122, there was no response
Then I upgraded firmware to 1.00o, and restored to yours old web interface, still same problem.
Then I changed all config files to yours default, and then I could move the head.
It was config.g file, as I had restored to the one I knew had worked!!

I have attached the bad config file, maybe someone can tell me whats wrong?

The command M111 255 at the start of that config.g will turn debugging on for all modules, not off. This may well cause problems if you do not have the USB port connected and Pronterface or something else connected and reading from it. This is because some debug messages are sent to the USB port using blocking I/O to prevent them from being truncated or lost. Non-debug messages are always sent using non-blocking output and discarded if necessary, so that having the USB port disconnected will not cause a problem. To turn debugging off, use M111 S0.

Ignore all this information about firmware. It's either a wiring problem, or a fault with the Duet. To test:

1. Make sure, when you plug and unplug wiring loom into the Duet, THE POWER IS OFF! Or you'll damage the stepper driver chip on the Duet.
2. Disconnect all motor wiring looms from the Duet. Compare all the motor wires, and check that wiring colour order is the same on each of them. On the Duet end, the order should be yellow, green, blue, red. On the motor end it should be yellow, red, green, blue
3. Reconnect one motor, and one checked wiring loom, and plug it into one axis on the Duet. Check you are plugging it in on the correct pins. Test to see if that axis works, on it's own. If it doesn't, try a different axis.
4. If all the axes don't work, there must be a short on the Duet board. Post a good picture of the Duet board, preferably with close-ups of the area around the stepper driver chips.
