Hi all,

Thanks,

First thing first : check the baud rate in the printer settings : anything else than 250000 bauds and it won’t work.

Hi raby,

thanks for your reply. I’ll check this tomorow evening and will reply. I andjusted the printer like it is mentioned in the manual “de_use_002 - CONNECTING THE PRINTER”. On page 3 is stated that the baud rate must be 57600.

Bye,

Schwanzlurch

Raby is correct about the baud setting

After you press connect in the software try pressing the reset button on the control board.
If this works disconnect the printer from the software.
Go to Config --> Printer Settings and make sure reset on connect is set to Disabled

Hi all,

I changed the baud rate as you told me but nothing changed. I checked in /var/log/syslog that the connection is successfully established. In the manual controll tab there is a debug group. If I press the “ok” button a green led flashes. Thats the only thing that happens.

Could you please help me?

Thank you.

Yes, it is working. I measured it before I connected it to the board. The black wire is ground, white one is +UB.

Non of the leds on the board flash. If I detach the 15 V power supply the red an green led near the usb jack is permanently gleaming. If I attach the power supply they are switched off.

when I connect the usb plug those two leds flash shortly one or two times. After that they are switched off.
In the very last line, on the left side I get a message “connected” (on the right side of this message the temparature is statet with 0°). There is no message in the debug window.

I think it must be a connection problem. May be the board is defect.

After you press connect in the software and press the rest button on the board does it respond?
If so do the following.

Disconnect the printer from the software.
Go to Config --> Printer Settings and make sure reset on connect is set to Disabled

Stop!
The board isn’t defect, I’ll bet.
the magic words are in the first post:
