GEC Gemini spindle drive from Boxford 260 VMC

[i2i]

hi, i've setup a few of these spindle drivers on mach3, but it's been a while since i've seen one. I used a diycnc sp4dc board to give the 0-10 isolated signal and run command. First off i would replace the old film caps with new ones as they will fail eventually, and it's pretty dramatic when they fail. I have some pics hiding on my comp somewhere of the layout, but there is a thread on this forum about wiring the gemini board to mach3

Hi i2i, Will do with the caps, prob tomorrow! im curious as to what other options there are instead of using these spindle drive units. I want to use the existing motor, but may look at other controllers (VFD) and see what they cost and if it is worth it...

Am wiring up my spindle controller now so hopefully i will be able to reply after!

i2i, i see your into retrofitting machines (as mentioned on another forum post) which machines do you retrofit? or is it whatever the customer asks? or do you do it to sell on?

Sorry to be so late replying, i seem to miss the alerts sometimes. I mainly convert Denford machines, but i've worked on Boxfords, Isel, old bridgeports, Harrison M300, M250, whatever is about. They can be customer machines or whatever i buy in, but they are getting a bit scarce now.

HI i2i Your not the chap i spoke to on eBay about modifing a boxford 125 lathe couple weeks back? Do you advertise your retrofitting on ebay?
