Hi Isaac,
I’m afraid I cant comment directly on this machine as I’m not familiar with it. However you need to be adjusting the "cutter lift" – this will adjust how high the cutter is lifted from its engraving position before moving to the next letter.
The lower the lift – the quicker the job completes but you run the risk of scratching if the material is a bit bowed or your table isnt totally flat
The higher the lift the less chance of scraping but make it too high and the job will take ages to complete.
On our old cipher machines this was controlled by a setting in the driver file, this was just a text file with various settings – I just bumped the number up re-opened the software and tried it – just make sure you have scrap in the machine in case it goes horribly wrong!
I would hazard a guess that the driver file for your particular table will be somewhere in the program folder.
