I have moved forward and am now working on finalizing the Proforma Invoice with StyleCNC.

They changed the machine from 240v three phase to 240v single phase to better fit my shop power. My road is a dead-end road and we only have 600v single phase wires running down the poles. I could pay to have 3 phase lines run, but I am also 400' from the pole and already have a 200 amp underground service run to the shop, so I don't want to have to trench again or put up new overhead poles. Not as easy and hanging another transformer and stringing a wire. I have rotary phase converters (2x-20hp) but they are just barely enough to run the entire package with enough space capacity to keep the voltages balanced under load (with some tweaking to the capacitors and wiring, per North American Rotary instructions - shout out to Matt there who walked me through the process of changing things to get better voltage balance).

I was upgraded from Fuling Inverter to Delta Inverter at no charger and it may be to facilitate the single phase voltage input. I am guessing that I can always use 3 phase power in the future with the machine as well as I have never seen an inverter that only accepts single phase input.

The Proforma Invoice seems standard and initially just listed the basic machine features. I have been slowly getting them to spell out every specific item that we have talked about. No pushback on any of it, but more details to begin with would have been nice. It's some big stuff, like specifications for the base metal thickness (6mm base, 8mm gantry steel), size of the Hiwin linear rails (30mm). Also including the specifications of the machine that are listed on their website like Traveling Positioning Accuracy 0.03/300mm, Repositioning Accuracy 0.03mm, Max Rapid Travel Rate 45000mm/min, Max Working Speed 30000mm/min, Collet ER32, X,Y Resolution <0.03mm. These specifications will allow the inspector to verify the accuracy of the machine. They have also stated that this request of mine would be added to the Alibaba order process so it is part of the trade Assurance contract "When the machine shipping, the machine is clean, oiled, greased, and rust-protected. And the measurement report of the machine is provided with the machine." I won't post it here at this time, but will consider adding it after the process is complete for others to use in the future.

I have a Freight Broker that has a team to handle the Customs process, so hopefully that goes well. There are too many different fee line items to tell what exactly I will pay, but they don't look exorbitant. Just a lot of $95 line items, some of which apply, some don't.
