sometimes when doing long programs 20 megs or better the cnc dnc via rs232 seems to timeout. It seems to happen with more complicated 3d (mold toolpaths). I think it is due to the 1 meg memory on the cnc VF3 being full and the handshaking between hyperterminal and it timing out? Does this seem possible and if so how can I increase the timeout so it does not happen, thanks
Are you using a USB to Serial converter? I've had similar issues with handshaking (or lack thereof) when using these. If you're using a laptop you may want to look into a PCMCIA-Serial converter. (SiiG, Quatech, etc.)
