Issues with motors..... Don't move

dc42

To check motors individually before you have homed them, them send G91 followed by e.g. G1 S2 X10 which should move the X motor 10mm in the positive direction. Replace X10 by X-10, Y10, Y-10 etc. to test the other direction and other motors.

Common reasons why motors won't move:

Motor current is set to zero. Send M906 without parameters and check that the reported motor currents are correct. Also send M913 and check all the currents are at 100%.
VIN is not present or the voltage is too low. Send M122 and check the reported VIN voltage. It needs to be at least 10V. If it is, try moving a motor (see earlier), and if the motor doesn't move run M122 again and check for under-voltage events in the report.
If it's a revision 1.04 Duet, the 7.5A fuse may have blown, for example because due to a short-circuited heater.

A common reason for VIN being too low is that the screws in the VIN terminal block are no longer tight., so VIN at the Duet drops when you try to move a motor or turn on a heater.

@dc42

I have do the test.... with next results

TEST A

 *PROCEDURE:*

  "To check motors individually before you have homed them, them send G91 followed by e.g. G1 S2 X10 which should move the X motor 10mm in the positive direction. Replace X10 by X-10, Y10, Y-10 etc. to test the other direction and other motors"

RESULTS:

 Dont move

TEST B

PROCEDURE:

Motor current is set to zero. Send M906 without parameters and check that the reported motor currents are correct. Also send M913 and check all the currents are at 100%.

RESULTS:

M906

Motor current (mA) - X:1200, Y:1200, Z:1200, E:800:800, idle factor 40%

M913

Motor current % of normal - X:100, Y:100, Z:100, E:100:100

TEST C

PROCEDURE:

VIN is not present or the voltage is too low. Send M122 and check the reported VIN voltage. It needs to be at least 10V. If it is, try moving a motor (see earlier), and if the motor doesn't move run M122 again and check for under-voltage events in the report

RESULT

Supply voltage: min 24.5, current 24.7, max 24.9, under voltage events: 0, over voltage events: 0, power good: yes

TEST D

PROCEDURE:

If it's a revision 1.04 Duet, the 7.5A fuse may have blown, for example because due to a short-circuited heater.

RESIULT

I have changed fuse, 7,5A. And the same.

All works, minus stepper motors

I have checked screws in Vin terminal.... are ok

peirof

For tests i have do....

All, minus motors, works....

peirof

If i conect a multimeter, to axis sockect, PIN X and Y (i dont know what pins)...... and command a move order to printer, that involves that axis, i have to see Voltage in multimeter? What range?1.0 A, aprox?

dc42

You can connect a multimeter set to a voltage range to pairs of stepper driver output pins, but be very careful not to short them together!

When you command a motor to move for the first time after powering up the Duet, does the axis become stiff and harder to turn by hand?

Please try commanding some motors to move, then send M122 once and post the report here.

peirof

@dc42

i send by console G91 and after G1 S2 X10.... and axis stiff, the same with Y and Z

after send a M122, the results

Hi,

An idea it's make a Soft reset... How would the procedure?

Hi,

Sending M999 causes a software reset.

peirof

@dc42 Ok... Later try... Exist, in Duet, a Hard reset?

M558 P8 I1 R0.4 F500 X0 Y0 Z0; M558 P8 I1 R1 F300 X0 Y0 Z0 H2 / M558 P5 I1 R0.4 F300 H5 X0 Y0 Z0 T2400

I could be way of the mark here but in this line
M558 P8 I1 R0.4 F500 X0 Y0 Z0; M558 P8 I1 R1 F300 X0 Y0 Z0 H2 / M558 P5 I1 R0.4 F300 H5 X0 Y0 Z0 T2400

is the semicolon directly after the Z0 ok or does it need a space in there?

@dougal1957

i am not sure, but think this is not the problem, the printer has been working with these config.g, months....

peirof

Well....eeee, not, bad.

I have do the test i have comented, soft reset and with a new MicroSD, reinstall printer.... and the same.

ALL WORKS (HEATERS, TERMISTORS, ENDSTOPS, ZPROBE,....) MINUS STEPPERS MOTORS

Only rest, think, is test of drivers of Duet, think TMC2660, are working ok...

How can test this point?
Its strange that all drivers goes off at the same time. Why?
Something more to test?

These look bad....

Now i have no ideas.....

@dc42, please HELP!!!!!!!!!!!!!!

dc42

Please verify the following:

When you power up the Duet, initially it is possible to move the carriages of your printer by hand (slowly!), because the motors are not energised.
If you send the following commands:

G91
G1 S2 X-10

then the X motor does not move.

After sending those commands, the X carriage is difficult to move (because there is current in the X motor). But the Y and Z carriages are still easy to move.
Sending this;

G91
G1 S2 Y-10

doesn't make the Y motor move, but does lock the Y motor.

Sending this;

G91
G1 S2 Z-10

doesn't make the Z motor move, but does lock the Z motor.

After sending these commands, there are no error messages reported in the GCode console.

Is all of that correct?

peirof

@dc42

No, it is not correct.

The motors ever, after send the gcode (G1 S2 X-10 or G1 S2 Y-10 or G1 S2 Z-10), are smooth to move, are not energiced....

In that case, I think there may be a problem with the ENN signal that goes from the processor to all the drivers. This signal is also present on the expansion connector (see the label underneath for which pin it is). You could measure the voltage between it and ground (which you can connect to on any endstop connector) using a multimeter. With USB power only applied, it should be at +3.3V. When VIN power is applied, it should drop to 0V, which enables the drivers.

peirof

Hi,

If I did not understand wrong, the procedure would be:

1- Disconnect, Duet3d Board, from power.
2- Connect Duet3d, with the USB cable to a PC.
3- I check the voltage, in the expansion module, between the pins, pin 28 (ENN) and pin 2 (GND).
4- With Duet3d Board, WITHOUT ELECTRIC CURRENT but with the USB connected, the reading on the voltage meter would have to be 3.3V.
5- I turn on the PSU, as soon as I turn it on, the voltage should drop to 0.0V.

Okay?
