3D Digital Duplicator

Postby GrandpaB » Thu Jul 27, 2017 1:54 pm

I am considering buying NWA's 3D Digital Duplicator. Has anyone tried it and how does it work? I'm looking for the good, the bad, and the ugly.
Thanks for your help

Need to read the answer to this question, another place said that it was a problem child and was being worked on around the same time as this post. Has it been fixed or is this a waste of time and money?

I purchased the 3D digital duplicator and it was a total dissappointment. I also have a Small Carvewright with a duplicating probe. I am reproducing the carvings in a dresser and needed this to work on my new HD4-Extended. The probe does work, however it is very slow and the ruby tip spring pressure is so great that it dents the surface of the wood every place that it touches. I offerred to work with NextWave engineering to improve the operation and performance of this probe and they totally refused. On my first scan the probe bent and became unusable, I returned it for a replacement which they did after much discussion, with them telling me that I had set the probe speed too fast, that it was all my fault. The probe had two defects, one was in the cable on the plug end and the other was that it failed to break contact when the prob deflected in one direction. That would tell the controller to keep diving down which eventually bent the probe and damaged the piece I was scanning. When you set a virtual depth, the firmware drives down until one of the 3 contacts within the probe opens. If your piece is irregular, and the probe is no longer over the piece but is still within the scan area, the probe fully raises when it hits the virtual depth, moves the specified amount and drives down again, taking an immense amount of time and a lot of wear and tear in the z axis. NextWave told me to allow the machine to touch the bed. OK, now I had to make a waste board as the bed, as you know is slotted. That did help the speed . . . . . Some. I ended up casting the desired carving on about a 9" x 14" cast. I attempted scanning this using NextWaves settings for speed, touching the wasreboard, etc. As an comparison, I scanned this cast on my Carvewright and it took about 3 hours. On the Shark HD-4,it would have taken over 3 days running around the clock!! I returned the new replacement probe unused, and they refunded the purchase amount, less the taxes which I had to eat!!! I was totally disappointed with NextWave's interest in improving the performance of this 3D digital probe. I DO NOT RECOMMEND it!!!
