Hi All I am a newbie to this 3D printing and I seem to have a problem with reprap program I can get repsnapper to create pieces with the Prusa I have built even though I cannot use the calibrate on the simple page. But I cannot get the reprap prog to work. When I start the prog the Dos screen says there is an error opening com port. I have loaded theFTDI driver and all seems well with that. I am useing windows 7 home. I dont know what other details to give you all can you please help.

Your port under Windows 7 is probably COM3 (although it could be something else).
Verify what the com port is and then in the RepRap Host Preferences dialog window, Globals tab, make sure that the BaudRate is correct for your firmware (by default 19200) and the Port (name) (left hand column, bottom) is correct "COM3" or whatever is correct for your system.]]> rhmorrison RepRap Host Tue, 26 Apr 2011 03:59:58 -0400 https://reprap.org/forum/read.php?12,81958,81958#msg-81958 https://reprap.org/forum/read.php?12,81958,81958#msg-81958 I am a newbie to this 3D printing and I seem to have a problem with reprap program I can get repsnapper to create pieces with the Prusa I have built even though I cannot use the calibrate on the simple page.
