Arclight Dynamics Arc Pro Ultra V3 4x4

The Arclight Dynamics Arc Pro Ultra V3 4x4 is the smallest full-size table in its series, the Arc Pro platform running Arclight's own Arc CNC software. Its cutting envelope is 54 x 49.5 in, with 9 in of Z. A sheet from 4 x 8 stock fits across it with a few inches to spare, but only about half of its length goes on at once.

Motion on the Arc Pro Ultra V3 comes from NEMA 34 stepper motors working through planetary gear boxes, on a dual-drive gantry with machined aluminum risers. The guides are Hiwin 20 mm precision linear rails with dual seals and scrapers, and the Z axis is a ball screw, which keeps backlash out of torch height moves. Positioning accuracy is listed as 0.001 in. The frame is steel and stands on all-in-one leveling rollers, so the table can be rolled into place and then levelled where it sits. Arclight rates it for 1.5 in mild steel.

This is the size for a shop that counts floor space first. The base measures 61 x 61 in and the table weighs 800 lb, light enough that the standard rollers make moving it a one-person job. Its water pan holds 53.4 gallons. Overall dimensions with the gantry and cabinet are listed as 81 x 102 in and 74 in tall, which is the figure to check against the bay, not the base.

The control is Arc CNC, software Arclight wrote for the Ultra tables. It runs on industrial Linux and talks to the table over Ethernet. The functions that matter in daily use are the recovery ones: fast forward and rewind along the cut path, start point recovery after a power loss, and an auto rip cut for trimming off a remnant. Plate skew can be set in software instead of nudging the sheet square. Torch height control with dynamic voltage sampling is part of the system. The plasma cutter is chosen separately when the table is configured.
