Re: [CAD_CAM_EDM_DRO] Re: Gecko burned - fixed for now

Hi Keith,

I will be using treadmill motors from surpluscenter.com, item number
10-1573. Carriage to the UK cost more than the motors but they are still
lots cheaper than anything I can get in this country. Surplus center
were very helpful.

The motors are designed to be foot mounted but they have a nice big
flange on them that can be drilled with the same bolt holes as the
current motors. They are smooth to turn by hand with only a little
'cogging' and will run down to about 1.5V.

I intend to use 200CPR encoders(giving 800 steps/rev) and I will
probably gear them down 4:1, giving a resolution of 16000 steps/inch.
The Z axis will probably stay 1:1 because I don't fancy trying to change
the belt :-)

I will go with Rutex drives, not because I have anything against the
Gecko drives but because I have future plans that will make use of the
SPI facility.

I will let you know how I get on...

Les
