If you are getting an “RS232 ERROR” during DNC there are two solutions:
Use DNCX instead of DNC:
CD,10<enter>
DNCX,FILE+
If you can’t use DNCX because the Fadal control version doesn’t support the feature then you will need to lower the baud rate. We can send you the USBCNC.INI file and instructions to change the default baud rate on your Calmotion unit. Or see the user manual.
Create a USBCNC.INI file, add a line CNC=9600 to the USBCNC.INI file, then use CD,8
See user manual for details about the USBCNC.INI
