I have retorfitted about 10 of the techno systems. Only 3 were servos. The 3HP router will cause the Z axis to drop if power is lost or the output of the servo amps are not engaged. The XY axis servo are bout 300 oz in and the Z axis is aboutn 400 oz in peak.
I used an airsping from Mcmaster car as the simple solution. I can get you the part number. I drill and tapped for a 5/16 hole on the bottom of the plate that hold the router. Then I made a L bracket that fit on top of the Z axis and connected the top of the air spring to that. I used Gecko drive G 320 servo amps.
