Welcome to the SeeMeCNC Community

Hello all
I've just finished putting together my Max, have arduino running and have sent over the repetier 091 rostock master.
I can find the printer on com4, and the arduino apparently uploads correctly to the printer.

Mattercontrol seems to have it's own ideas.. it just sits there spinning on nothing while it tries to find the printer...

Ive dont the basics of searching this forum for other mattercontrol connection issues (non found), restarted the printer and pc (there was quite a few programs loaded during this process) the device manager says the printer is known and all ok.

ive done several auto-connect attempts, and several manual connects by just selecting serial port 4 (where the arduino sdk says the printer is supposed to be)

as far as the printer is concerned, its display is all ok,

any ideas??

Do you still have the Arduino IDE open? I believe MC can't connect if Arduino IDE is still open and claimed the COM for its own use.

Can't say I've tried using MC's autodetect so I don't know if it works or not. Have you configured a printer profile in MC so it knows what it is trying to find?

Did you load the RAMBo driver in Windows? I think Arduino IDE can talk to the RAMBo through its generic MEGA2560 profile, but for a program like Matter Control or Repetier-Host to connect you need the RAMBo's driver in place.

thanks for the thoughts.

I've tried talking to the printer both with arduino open and mattercontrol, and with arduino closed and matter control open. it makes sense that only one gets to communicate at a time..

Matter control asks if Id like to install a driver, the name of which isn't specificed at this point.

I have the rambo driver, and it was installed via device manager...

Im still getting an unending trying to connect, but if i cancel the search, mattercontrol has the 'connect' field in the top left hand corner, with my printer name, and status reads 'com4 in use'

arduino is not running at this point (fresh restarts)

i'll give the repetier-host software a shot next

repetier-host gives more information.
i try to connect via com4, or auto, and it returns with an exception handler for portName does not start with COM/com or does not resolve to a valid serial address

This sounds like a problem with the RAMBo driver. I suggest uninstalling the driver, downloading a fresh copy from the SeeMeCNC download page http://download.seemecnc.com/RAMBOUSBDRIVER.zip and install it again.

yup, i grabbed that a fresh download this morning, and then when i checked through arduinos port tabs, the printer was gone. so i freshened up everything. So thats: restarted the pc, restarted arduino, reflashed the eeprom_clear to the printer, then put the Repetier.ino file onto it. closed arduino, and opened mattercontrol. which it then autoconnected to the printer
gotta love restarts!
