Guarda onestamente non so più cosa dirti.... hai collegato correttamente il motore?? È possibili che vibri perché hai collegato male gli avvolgimenti motore male? Misuralo con un tester... se hai cablato male quella parte il motore mette in movimento entrambe le coil e quindi il motore vibra....

Ciao,

non vedo da nessuna parte il comando per settare la duet in cinematica CoreXY. Lo hai impostato?

M667 S1 ; Select CoreXY mode

@dc42 understand. Then no auto resume option?

https://duet3d.dozuki.com/Wiki/Gcode#Section_M911_Configure_auto_save_on_loss_of_power

Raaa Resume threshold in volts. Must be greater than the auto save voltage. Set to a high value to disable auto resume.

Ciao,

Devi collegare i poli ENA+ e ENA-.
Inoltre il comando esatto M569 è il seguente :

M569 S"orario o antiorario" P"numero motore" R1 T4:4:5:0

Hai l'obbligo di mettere tutti e 4 i parametri nell'opzione T o non funzionerà correttamente

Ciao Giuseppe,

la tensione la puoi misurare con un semplice multimetro tra i poli ENA+ e ENA- in uscita dalla breakout board.
Io la ho provata e posso dirti che funziona bene!
Se non colleghi i poli ena+ e ena- probabilmente il driver esterno non alimenterà mai gli stepper.
La duet ha la possibilità di spegnere gli stepper tramite il comando : https://duet3d.dozuki.com/Wiki/Gcode#Section_M18_Disable_all_stepper_motors

M18.

Ti conviene usare questo comando e collegare tutti i cavi necessari al funzionamento dei driver esterni.

Inoltra considera il comando :

https://duet3d.dozuki.com/Wiki/Gcode#Section_M569_Set_motor_driver_direction_enable_polarity_and_step_pulse_timing

M569 e imposta correttamente il tempo per i microstep. Poichè i driver esterni di solito hanno tempi di microstep maggiori.

Firmware 1.21
M911 S25.0 R50.0 P"M913 X1000 Y1000 G91 M83 G1 Z3 E-5 F1000 G90 G1 X0 Y0"

I’ve found that if I set the parameter R to a normal voltage like 24 volt then the auto pause is working properly... maybe a bug?

I’ve set the M911 option on my duet but, also manually decrease volt from 24 to 12 volt with a decrement also step of 0.1V duet won’t stop.

There are need some specific file in order to activate this features?

I’ve set M911 to pause print at 22 volt and resume at 30 volt ( no auto resume ).

Please help me!!

Dear All,

how is working the second sd? Is possible to connect a breakout board directly to the duet without passing through the paneldue?

A breakout board like this :

Thanks in advance

Dear All,

i'm trying to find the most efficient way to send a gcode file to the duet using the usb serial connection.
Right now i'm sending one row at once by a java software. It took very long time! By wifi and duet web controll a 20 mb file can be transfer at rate of 650 kbytes/s, i can reach only 10 kbytes/s. Maybe some problem on the library ( JSerialComm ).

Anyone has some ideas on how increase the speed? Maybe sending the file without reading one row at once?

Thanks in advance

I lost a lot of time on bltouch. I think there is a bug in firmware with some config. Try with a config standard like this and try the bltouch!

For the reading of 1000 yes this was normal also for me.... you need to send a specific test command in order to check the correct working of bltouch. You must use : M280 S3 S60 I1 if you want to see the value 1000 drop to 0
