Yup, the larger (1400mm x 600mm 7x7) grid seems to have fixed it for me!
It’s annoying that we ask you to pick your own grid size without really any guidance on what is a good size. I will work on making it so that the machine picks a reasonable size automatically so it’s not something we have to enter anymore. There is no reason for it not to do that automatically…I just need to do some testing to figure out what is a good size
