RotatoVIEW — see the stock, read the signal // standalone · 4-axis · windows

The 4-axis G-code viewer
that actually works.

Load rotary G-code and see the real wrapped toolpath — the C axis unrolled onto the part, drawn as a curve on the cylinder. Scrub the whole program by machining time.

You've fed your rotary .nc to a dozen backplotters. They choke, or they draw a straight chord from C0° to C350°, or they plot C as a phantom fourth line going nowhere. RotatoVIEW doesn't — it's RotatoCAM's main engine, reconfigured as a standalone viewer. The exact backplot that drives the CAM app, pulled out on its own.

What it does

Unwraps the rotary — correctly

X + C + Z move together and draw as a true helix on the part, with arcs subdivided so a wrap reads as a curve, not a chord through the stock.

Time scrubber + estimate

The slider scrubs by real machining time (G93 inverse-time and G94 feeds both timed right) — drag to halfway and you're at half the cut, with an MM:SS / total readout.

Doesn't choke on big files

The same parser that drives RotatoCAM — tens of thousands of moves load fine, feeds vs rapids vs retracts colour-coded.

Any 4-axis post

Reads A / B / C rotary words; pick which linear axis is radial for posts that wrap on Y instead of Z. Not just RotatoCAM's output.

It's built into Pro — free.

The viewer lives right inside RotatoCAM Pro — File ▸ Open G-code for backplot opens any program. If you own Pro, you don't need the standalone. The $19 RotatoVIEW is for when you only want the viewer.

$49  RotatoCAM Pro = every machining strategy + the G-code viewer. One price, no subscription.

⚠ RotatoVIEW views G-code — it does not run your machine, and a clean backplot is not a guarantee the program is safe. Verify every program and air-cut first. Provided AS-IS, no warranty.

Need to make the toolpaths too? RotatoCAM turns an STL into 4-axis rotary G-code — free Community Edition, or Pro for the full toolbox (Pro already includes this viewer).
