I use an Automation Direct GS2 VFD to drive the spindle on my Bridgeport, controlled by linuxcnc over serial, using a USB-to-RS232 adapter. There is a register you can set via the faceplate on the GS2 to change the baud rate. I run mine at 38,400. I see that you're driving your VFD with mb2hal (i use gs2_vfd). And i see that mb2hal also supports different baud rates (though it's not documented). So my point is: I think you can increase the baud rate and reduce the amount of time your VFDs take to respond. -- Sebastian Kuzminsky ------------------------------------------------------------------------------ Download BIRT iHub F-Type - The Free Enterprise-Grade BIRT Server from Actuate!
