In late 2010 ZPS-CNC USA acquired the assets of 3S incorporated.

ZPS-CNC USA has merged support for the Tree knee mill products into our core business. With nearly 60 years experience on Tree products in our office and 50+ more years experience with our field service people, there is no comparison to the support ZPS-CNC USA can provide for these products.

With so many machines supported for so many years, ZPS has amassed over $1.5M in total inventory, including many used and refurbished CNC control parts for Dynapath Delta 10-2000, plus quite possibly the only stock of the impossible to find DELTA 30 processor boards.

In addidtion to the parts, we provide in-house repair of all the Dynapath CNC Delta controls from Delta10-2000. We offer quick turn around and quality work, plus we can not only support the cnc control, but how it is interfaced with the machine tool with our years of experience.

Nobody else can offer the full support package that we can.

We also repair the Tree PC-2100 (Acramatic A2100) controls and provide safe backup and data recovery when necessary. Our repair prices are extremely competetive and normal turn around time is 24-48 hours in most instances.

ZPS does NOT offer CF card "upgrades" for the 2100 controls due to long term reliability reliability problems. We offer a solid state plug in IDE module to handle the control's data needs.
