Speed slowing when engraving multiple copies

Ruida controller on a120 watt machine. Engraving wood coasters at 11.5% / 200mm with a Z offset of 2mm, all on one layer. Engraves perfectly on the first one, proceeds to second one and the X travel is noticeably slower although the machine still displays 200mm, so I repeat the process and timed the results. The entire job took 13:55…the first one was completed in 5:30, the second one took 8:26 to complete. Any suggestions?

Not without more detail do I have any suggestions. If you can provide the following:
