Hi,
I ran into some problems while trying to use cura (2.4 as well as 2.5) with my cheap Prusa i3 RepRap Machine. The machine does not show up as connected USB-Printer in Cura.
Problem 1:
The USB-Controller would not be recognized as USBSER from Windows instead Windows will recognize it as VCP0-Device.
Fix 1:
So I changed the USBPrinterOutputDeviceManager.py to not only look for USBSER-Devices.
Diff for USBPrinterOutputDeviceManager.py (Cura 2.5.0):
263c263< if not only_list_usb or "VCP0" in values[0] or "USBSER" in values[0]:---> if not only_list_usb or "USBSER" in values[0]:
Problem 2:
Next problem i ran into was that the USB-Controller in my case does not run with a baud-rate of 115000 the controller I use works with a speed of 57600.
Fix 2:
Modification of the stk500v2.py, after timeout trying to connect to the USB-Device with a baudrate of 115000 retry it with 57600.
Diff for stk500v2.py (Cura 2.5.0):
31c31,33< raise ispBase.IspError("Failed to open serial port")---> #Modified Exception to connect to other printers which use Arduino with a Baud-Rate of 57600> self.serial = Serial(str(port), 57600, timeout=1, writeTimeout=10000)> #raise ispBase.IspError("Failed to open serial port")
This is more a dirty hack cause I used raising exception to try it with new settings. Maybe anyone has an better idea.
Maybe some admin sees this and trying to get this infos to the DEV-Team!
I would love to use cura ootb in future versions without dirty-hacking some files
