Just to let everyone know things got a bit frantic before I left for the US and I forgot to bring the spares kit back to the shop before I went to the airport. As soon as I get back I will be shipping out the motors plus the spares kit which consists of extra grub screws o-rings and a spare delrine plunger. I will ship a new manual as well as it might be a bit confusing with what voltages to use. I wrote it with the fast motor in mind but half the machines shipped with fast motors and half with the slower motor. So if you get a machine with as slower motor voltages are 5-7 volts and the faster motors 5 volts. The motors are rated at 7.2 volts so they can be run a little higher with out damage and you may also need to run them a little higher at first to bed the plungers in. Two artists have received their machines and already done some work and first reports are they really like the machine, I have tagged them on face book so check them out. When you get your machine please feel free the email me any comments or suggestions you might have.
