I finally was able to run the same image on both pieces of software. Both images are approx 1000x1000mm.
Feedrate – 1200mm/min
Min 0 & Max 255
The conclusions I came up with is the resolution on the PL software is a little better and that speed matters and it affects both a little differently. I do think the PL software is worth the money since it was only $40 but I do think with a little tweaking the I2G could work well.
I hope this helps
