DSP Purchase Advice needed

[oldsourkraut]

I am building a 80W laser machine roughly based on the Buildlog.net laser only larger. I plan on using a DSP for the machine control and have read through the descriptions of the 3 controlers offered by Lightobject. I may be missing something but I don't any difference between them based on the descriptions provided. I have no problem paying the extra $40 to upgrade from the lowest priced unit to the highest priced unit if there is a benefit. Can anyone tell me what the differences/benefits between these DSPs? Thanks!

R5 is from Ruda
AWC608 (older board) and X7 are from Anywell

For K40, go for AWC608 or X7 because so many folks are using it for the upgrade.
R5 is good, especially for bigger machine because it has decelerations and a little more features. X7 is not bad because the programmer I know well so I may able to ask him to make correction if necessary.
