Spindle GO!

My 2200watt water cooled Chinese spindle from automation technologies with accompanying inverter arrived yesterday. After driving around town to various post office depots I picked up the final pieces to the puzzle. I also had to find a water pump and plumbing. I ended up buying a cheap $69 fountain pump that can do 170gph with a 5ft head with a flow control. I also bought a few plastic bits to convert from the 3/8 to 1/4 that the spindle takes, all ID measurements. Which was part of the problem. I bought braided tubing so that there would be no chance of the hose getting crushed, not that it should, just in case. I forgot to take into account the extra OD but luckily the cheap princess auto stuff is actually two separate layers so I just peeled off a little at the motor so it fit it’s crush connectors. I wired up a 3 phase switch to the inverter and bought some 4 conductor 16ga shielded? For the motor.

As per tool designer build log videos I setup the wiring.

3 phase = Inverter.
110v = R
110v. = S
110v. = T
Gnd. = E

Motor. = Inverter
1 =U
2 =V
3 =W
4 =E

I’m not 100% on the 10k pot wiring,
ACM=GND on pot
V1= Outside leg of pot
10v=center leg of pot
DCM=switch+
REV/FWD=switch sense

So after getting that all together and verifying connections I hooked it all up and away it went. I just wanted to verify it was functioning and success. Tomorrow my job is to finish putting it back on the machine and make a more permanent mount for the switch and inverter and water pump. There is still endstops switches to install and after reading more about the hall effect type switches I think I might make them for homing. Repeatable/accurate and no moving parts to boot. I still think switches are fine for end of travel but for initial homing sounds great.
