Boss 1-7 use steppers, and 8-12 use servo motors. What's the other differences between all the Boss models? Is it just controllers?
What's the difference between Series I and Series II machines.
Some sort of matrix showing the different models and features would be most useful.
Any help appreciated.

Hello Mike
I have a series I CNC which was origonally fitted with a Boss 5 control the ajax cnc system which you refer to is a kit complete with 3 x 29 lbs ins dc motors with shaft encoders built in, a card which fits into the PCI or ISA slot of a PC and a 3 axis servo control board also comes with intercon interactive control software with different options to suit your requirement.
On my system I have removed all of the origonal electrics except for the 240 volt - 110 volt transformer which I used so that I can run my machine on single phase also using a VFD single to three phase inverter for the spindle motor and using the speed control unit from Ajax gives me programmable speed control from the software. Upto now I have been very pleased with upgrade and would reccomend it to anyone considering a similar retrofit be it on a series I or series II I had one of these previously some years ago before the advent of retrofits were freely available, wish I still had it as well as the series I which would be just the same to convert.
If you email Jesse at Ajax controls he is very helpful also the dvd on programming the machine is very good.
