Zenford Zeigler Retrofit

Thanks Peter, Would be interested to see what you have there. Not sure the best way to contact you directly?
I have not been able to really do much with my Zenford in quite a long time. I started a little machine shop, and dont get much time to play with the retrofit anymore. Would love to get back to it though. Might be a bit like yours Russell... a super long project, haha

Hi mat hope your build is going well, 
about 12months ago i bought a retro fitted zenford mill the same as yours it works great other than i suspect i have a worn spindle bearing that needs to be replaced is there any chance you would be able to send me some photos of the spindle drive section of the manual, I'll be more than happy to pay for your time.
or if you know where I could buy one?  Hope to hear back

thanks 
Zac 

Hi Peter,
I know that it's been a while, but would you still have the zenford zeiglers available by any chance.
Cheers
Andrew

Hey Matt, I don't know where you are at with the retrofit but I thought I'd share some info about mine as it may help you.
I've just got the X axis going using closed loop to the controller this weekend. I am setting this up with Riocore, there is a very long thread on this forum about it, I'd recommend having a look.

I am using the original brushed DC servos, I removed all the resolver and tacho generator bits out from the end, mounted a perspex plate and fixed a CUI capacitive encoder. I did build my own H Bridge and controller board, had a couple of issues but it is now working.

The actual part doing the tricky stuff is a $30.00 fpga board (Gowin Tang Nano 9K)

There is something about turning the servo by hand without the motor drive engaged and watching the DRO update on screen!

Cheers.
Russell.
