Only commenst I have is that the CDE cnc1 is not designed to run from mach3 as it has its own program easycnc.
The zapp box has higher current handling of 4.2 amp over the CDE's 3.5 although the CDE drivers are actually listed as 4 amp in the manual.
I have the CDE cnc2 box and I am so far pleased with it although easycnc is a bit of a struggle to get to grips with.
I think you will find the whole process has a steep learning curve but ther again it is supposed to be a hobby!!!!
