What is the best way to destroy the Duet2 motor driver?
-
Hello
I have two Duet2's.
But I have destroyed two Duet2's.
In both cases the TMC2660 has been destroyed.
The error message that comes up is thisWarning: motor phase A may be disconnected reported by driver(s) 2
Warning: motor phase B may be disconnected reported by driver(s) 2It appears in X, Y and Z.
I can move +/-50,10,1
but I can't move +/-0.1 anymore.
I don't think there is a problem with the cable.
I have used a jumper wire to check.
I don't know what I have done to destroy the Duet2.
Please let me know what you think. -
@kotuo that doesn't mean the driver has been destroyed, not yet anyway.
It typically is a wiring issue.
What motors are you using? Have you confirmed the wiring of the phases of the motor are correct?

@jay_s_uk Thank you for your reply!
I have checked the phase using a jumper wire.
I have used this method to connect the motor so that the torque is applied.
getting the following error messages from all the motor drivers.
Warning: motor phase A may be disconnected reported by driver(s) 2
Warning: motor phase B may be disconnected reported by driver(s) 2 -
@kotuo do you have the part number for the motor?
-
@jay_s_uk Thank you for your reply!
Here are some pictures of the motors we use
Top is Z-axis
In the middle is the X.Y axis
The bottom is the extruder -
Are you getting those errors from all drivers, or just driver 2?
If you move the motor and wiring from driver 2 to a different driver does the error move with them? If you move a motor and wiring that works on another driver to driver 2 does it also give the error there?
Please post your config.g and the results of M122 and M98 P"config.g"
Do you know the max rated motor current for your motors?

check the wiring on the plug with the duet connector

I don’t have enough experience on Duet, but in general, the best way to kill the driver chip is to connect/disconnect the cable with motor power on. A broken cable or bad connector with intermittent connection equals to disconnection.

@phaedrux Thank you for your reply.
I am getting the following error statement for all motors when I do a home-all.
Warning: Motor phase A may be disconnected as reported by driver 2.
Warning: Motor phase B may be disconnected as reported by driver 2.
The extruder drivers (E0, E1) have not been checked.

Nidec [KV4239/KF4242] is not listed in the current datasheet, so I guessed from the latest version of the model number: 2A.C17HD2020, no datasheet found, probably: ２A

@kotuo please measure the resistance of each motor phase, also measure the length of the motors. From those figures we can estimate the motor characteristics by comparing them with other similar motors.
Is this ab existing 3D printer than you have upgraded to Duet? If not, where did the motors come from?
Are you using 12V or 24V power?

@dc42 Thank you for your reply.
The motor I'm using is an existing motor.
The power supply is 24v.
Nidec : KV4239 A,0.64Ω B,0.64 Ω
C17HD02 A, 0.63Ω B,0.63 Ω
Nidec: KF4242 A,11.6Ω B,11.6Ω -
@kotuo thanks. What is the length of those motors, not counting the shaft?
The Nidec KF4242 motor has a high per-phase resistance. It is either not suitable for use in a 3D printer, or it needs a low current. If connected to a Duet with the current set too high, the Duet might well give "phase may be disconnected" warnings for the driver it is connected to.

@kotuo I see disconnection reported only for driver 2 - which drives Z axis. Do You have jumpers on the second Z motor connector?

@dc42 Thank you for your reply.
Size of the motor

Red line 42mm
Blue line 42mm
Green dot (length without shaft) 38mm
C17
Red line 42.4mm
Blue line 42.4mm
Green point (length excluding shaft) 39mm
KF4242
Red line 43mm
Blue line 43mm

@boa Thanks for your reply.
I have the jumper on the second Z-axis. -

You have the space in the wrong place, should be

@phaedrux Thank you very much.
It was a short sentence, so typing it by hand was a big mistake.
Here is the result

@kotuo
are you sure that red and green are one phase?
because normally red and blue are one phase -
@veti Thank you for pointing this out.
I have no choice but to change the order of the cables because the cables I am using are twisted on the motor side and I do not have the terminals on the motor side.
