I'm just starting my CNC journey and want to produce shapes from double-wall (5mm/0.2") cardboard. From fairly lengthy research, I believe my best option to do this in a clean, repeatable, accurate way is with an oscillating tangential knife. The only show in town on this seems to be the EcoCam EOT-3.
As a beginner in the UK, I'm drawn towards the Ooznest Workbee Z1+ as a starting point for a machine. This uses the Duet2 controller. What I'm not clear on is how realistic it is, as a genuine beginner without a technical background, to buy an Openbuilds-type machine and an EOT-3 and make them work together. There seems to be a genuine dearth of information on the EOT-3 online. I gather it needs use of a 4th axis to turn the knife blade, and I understand the Duet2 can support this, but I'm concerned about getting stuck early on and left with a £1400/$€1600 cutting block which I can't make work.
I've reached out to Ooznest for guidance, but understandably been told they have no experience with the EOT-3 so can't help out.
The only alternative to the EOT-3 seems to be a dragknife. This looks to have quite a few disadvantages vs the tangential knife in terms of accuracy, flexibility and quality of cut. But I'm not experienced here either, so perhaps there's an option here.
