unfortunately I have to start a new thread about a connection problem with the k8200 printer.
I have just finished building the K8200 3D printer. So far everything went quite fast and smooth and I was able to finish the installation after two days (one for the mechanic and the second for wiring and soldering).
Unfortunately I just ran into problems while trying to connect the printer to the computer using Repetier v.1.6.0 on both win7 and ubuntu, without luck.
Repetier can not establish an connection to the printer and giving me the following errors:
“No start signal detected - forcing start”
“Communication timeout - reset send buffer block”
What I have checked/done so far:
- voltage of power supply OK. ~15V when connected.
- settings in repetier
- re-soldering a cold soldering spot at the USB connector of the board
If i connect only the USB-Plug, the two LEDs light up and the computer detects the USB-COM-Chip.
One thing Iḿ not shure are the settings of the COM port in the system settings. Do they have to be setup? The manual does not mention anything about that.
(settings in system tray)
(settings in repetier)
When connecting the main power, the two LEDs switch off. They only light up very shortly when the USB is connected or disconnected. Nothing else, no other reaction from the board.
I this correct?
