Hi Phaedrux

I tried to print an other model with 'Repetier host' but that ended even worse the grinding sound was like 3 times louder and the glass fuse from the 24V inverter became extremely hot.

Here is the Gcode from the 'Testprint2' program

Hello dc42.

The testprint2 code was just from the firmware itself (User-Defined Macros.)

The speed and acceleration has been set to the default value.

Hello community.

I recently experienced a unusual problem during a dry test print.
(Just checking if the motor are working fine.)

When i move the motor manually with the head movement X,Y,Z,
everything works fine without a problem. But when i try the 'Testprint2' code,
The motors will behave very strangely.

The motors are are going to the the end-stops and the bed position.
And after that the problem occurs. When the machine wants to print, the motors are barely moving and make a grinding noise. The motors won't budge then until the test print is over.

Here's a video to explain it more easily:
https://streamable.com/kr4d7

(Note: the communication error was pure coincidence)

• I use a 24V inverter
• And a 0.9 angle stepper motors

A funny thing is that the grinding noise is even louder when i use an other software like repetier host. (It sounds like a diesel engine in my room)

I tried to change the steps to 16, 32, 64 and so on but that doesn't work either.

What can i do to Stop the grinding and print normally with the motors?

Thanks.

Hi @T3P3Tony

I installed some brand new motors to the machines and it is working perfect now. So the problem was the motor itself.

Thanks for the suggestions everyone!

Yes unfortunately there was no result,

The X motor kept vibrating so i guess the motor itself.

I increased the motor current to 1800ma so it receive a bit more power

But the X motor barely moves at 3000ma. and there is barely torque on the X motor when it moves. I think that i am just gonna buy a new stepper motor to replace X motor with a bit more power.

Hello,

Sorry for the inactivity.

I managed to get the motors moving on rod Y and Z, only the motor on rod X is still vibrating. I reduced the amps to 1.3A now in the firmware.

I do need to borrow a multimeter sinds i only have a industrial voltage meter

But the good news is that the problems so far has been reduced

Here are some images of my machine, maybe it can help.

I was thinking about adding ceramic Grease (fat) on the rods to reduce the friction. Should that work?

I have seen that industrial machines like lathes, CNC machines, and robot arms use it a lot. That gave me the idea to use it.

The json file says that it runs marlin

I totally agree that it is not an smart idea to double the amps in a motor that is only rated for 1.3A. Safety is priority number one here.
(My mom won't be happy at all when she hears the smoke detector in my room.)

M906: Motor current (mA) - X:3000, Y:3000, Z:3000, E:2000:2000:2000:2000:2000:2000:2000:2000:2000, idle factor 30%

M913: Motor current % of normal - X:100, Y:100, Z:100, E : 100 : 100 : 100 : 100 : 100 : 100 : 100 : 100 : 100

I am also afraid that my motor are mabye to small

• 42x42x34mm
• Rotor Intertia: 34g.cm2
• Holding torque: 28N cm
• Detent Torque: 1.6N cm

Thank you for helping

I managed to stop the vibration by increasing the motor current to 3000ma.
(P = U * I |12 * 3 = 36W of power.)
I use the 'Deltarunner glide system' to support the rods of the delta printer https://www.thingiverse.com/thing:2206030
The pros of this system is that it holds well againts the construction.
The cons of it is that it creates friction, so my stepper motor needs to work harder. I think that that was one of the problems why my stepper motor kept vibrating.

Most of the problems are finally solved!

Thanks!

Hello!

I tried to play a little bit with the steps per mm, acceleration and it looks that the motor is spinning a most of the time. It is still vibrating but its reduced alot now.

• I wired them with the color code 'Red, blue, green, black.'

• The motors work when i reverse them with the Z motor but also vibrating

• The firmware that i use is Marlin

• When i send M564 H0 i receive this comment 'Movement outside the bed is not permitted'
  -M906 returned this 'Motor current (mA) - X:1300, Y:1300, Z:1300, E:800:800:800:800:800:800:800:800:800, idle factor 30%'

• The motor are very quiet, and after some changes with the firmware it vibrates less.

Motor X and Y still won't move when i press home all so i think that i need to change something in the firmware for that

Hello there!

I got a small problem with my Nema 17 stepper motors.
The motors won't move at all and motor Z is the only one responding when i press 'home all.' Motor X and Y doesin't respond. I tried to change the settings with the configuration program (configurator reprapfirmware) like changing the steps per mm, acceleration, microstepping and motor current.
nothing worked so far.

My printer use the: Nema 17 42bygh34 (12V 1.3A)
My PSU is the: belpa gr 2402.50 (24V DC)
I tried to use a 12V PSU but nothing changed so far

I doubt that the motors are broken because it worked fine with my other controller board (Minitronics v3.0)

Could there be a problem that is hardware related like the wiring, or does look more like a software problem that needs to be fixed?

Thanks for replying

Excuse me for my late response,

I tried to change the settings by editing the IP with the M552 command and/or via the 'config.g' setting without luck. In the past I managed to log in by connecting it directly from the modem. After installing the 2 new routers the board won't connect anymore. They are both 2.4Ghz and the board is connected with an Ethernet cable.

Thanks for helping!

I got a small problem after installing a router.
The board can't be accessed anymore on the internet when i type the IP address linked to the board. The IP from the duet has been configured to "192.168.1.2."
The router has been configured to 192.168.178.3.!
It is connected to the blue 'Linksys' router via an 'Ethernet connection.'
I already tried to reverse the routers ip to 192.168.1.1 but without luck. Is there a way to reconfigure the ip from the board from 192.168.1.x to 192.168.178.x?

Thanks for helping

Sanny
