new to printing : cannot connect PRUSA I3 with MKS V 1.1
July 02, 2015 12:31AM
Hello,

I've got a new prusa i3, which I bought from another person.
The card is a MKS V1.1, windows 8.1 . My computer doesn't recognize it when I plug in the usb port (I have the sound, but repetier or cura doesn't let me control it or launch a print with UScool smiley.


What can I do?

Thank you!

You should connect the MKS board and see the devicemanager for the COM port it is assigned to.
Then use the same COM port in Cura or repetier.
I don´t know the default BAUD rate of the MKS, but you can try 250000 and see if it connects.

If you don´t see the MKS board in Win dev manager, you might have payed to much for the printer... sad smiley

Problem quite solved...

for prusa I3 I forced the drivers named : ft232r usb uart 驱动 because it was not plug and play, after forcing windows to use unsigned drivers.

Still, Cura works well but repetier can't get temperatures from the usb connection.

It's not important, so... solved!

thumbs up
don´t forget to disable auto-update in windows....
I´ve learned in arduino world, that they are always behind the schedule and need some time to adapt their IDE to the newest drivers.
I´m sure that other openSource programs have the same trouble ( repetier, Cura, printrun, etc. )
