The VR control software is not configured correctly and is searching the COM ports for the wrong kind of machine / control card. Mach3 was designed to use this port to send the step, direction pulse to the CNC controller and receive some inputs such as limit switches. It was mainly used to connect a PC to a printer. The IQView Site Connection is set to Connect to CNC/RS-232, and the RS232 baud rate should be set to match that of the controller’s or CNC’s RS232 port (normally 9k6).
The serial port on either the PC or Baldor card has been damaged electrically - try another port on the PC.ģ. The parallel port has been discontinued on PC’s for several years now. The RS232 port also enables connection to the IQ system current loop Lan through a CNC (e.g.
The serial interface receives code from the PC and moves the stepper motors accordingly. We've originally been using floppy discs for all our machines, but are finding it harder and harder to find good quality Imation brand discs around the. This device is a CNC router using an Arduino uC. RS232 port is being used on the PC by another piece of software - only one piece of software can use the RS232 COM port at any one time.Ģ. Okuma RS232 Setup (Almost there.) I'm going through the process of setting up RS232 communications for the company I work for, almost got it all sorted, just after advice on a couple of things. If you made this cable as shown, and still cannot get the PC to communicate with the machines via RS232 then your problems could be:ġ. This cable is also recommended for use when upgrading firmware via RS232 - this is because all pins are connected and will help prevent the firmware upgrading process from timing out with possible data noise and corruption. Add USB to Any RS232 CNC Machine with our USB Connect Solutions. This cable will work directly from the PC to the Baldor motion control card, thus bypassing any other cables and bulkhead connectors. FOR SALE USB reader - DNC transfer device. Use the following cable diagram to continuity check your connections from the PC, directly to the 9way connector on the Baldor motion control card.Įven try make up this cable in order to rule out cable/connector problems.
