Topic:   Received files to PC being altered

When receiving a file from the CNC machine there are now some characters being replaced/added in the received file. The corrections below are found on the CNC before the program is sent to the PC.

X1p. Z7.

Apologies - my text got chopped off. The rest of my text is below.

X1p. Z7. "p" should be a 0 [zero]
X0.95 M "M" should not be there

Any ideas what may be causing this?

Looks like data corruption. I mean data in the cab;e being corrupted. Could be cables too long or long cable running alongside some other electrical equipment.

But assuming it's been working correctly until recently then check the cable. The areas close to the connector or anywhere else it might move. If the cable looks good then see if you can open the connectors and check the solder joints. A dry solder joint may look good but can move very slightly. Sometimes just dabbing with a hot soldering iron fixes these things.

Just wanted to follow up - we tried a new null modem cable and the issue was resolved.
