Brother TC-225 / TC-229 adventure!

It shows 0v 

I put pull up resistors on all encoder inputs and inverted them in hal . Now atc works fine

What is happening without resistors:
If I put red multimeter wire on encoder +24v and black wire on encoder outputs it shows 0v when not active and -24v when active
If I put black wire on encoder gnd and red wire on outputs it shows 0v when active and not active.

Hi Ihavenofish!
actually I have Brother TC-215 with original Toshiba servo drives...and I manage to retrofit it ONLY with pin-to-pin replacement NC-Board with Mesa 7i92 and 7i77. It's work incredibly precice (I think due internal resolver) (precise is about 0.002mm)

first chips

So if your drives and motors initially work fine, I hope You can do the same and save cost and time.

Ready to share all info with all comunity.


 

Interested please help!
