Cornering on the DSLS3000

Just been setting up to machine a few large Tacho boxes, and rushing I forgot to turn the speed down. Since the result is interesting I grabbed the camera this time and took a few shots.

The machine is set up for metric working, the speeds are mm per minute. As you can see, the mill has no problem machining this type of box at full speed, but the DSLS3000 controller demonstrates its latency quite nicely. The first cut was at 1500mm/min and as one can see the controller has not get near the corner when Mach3 starts to move the second axis. Drop down to 600mm/min and it get into the corner a lt better, but at both 450mm/min and 300mm/min you can still hear it taking a little more material out on each corner. The 300mm/min is just about down to the tool radius of 3mm.

The machine works well, and while moving in air the higher speed is an advantage, but for cutting into corners one needs to slow down below even the fastest speed of the open loop controller.
