Attention:

● If you need belt driven WorkUltra CNC, please leave a message to us!

● The recommended maximum speed of a 1500mm lead screw is 400RPM, however, in practical terms no cut will be performed at this speed. Cuts and engraving are done at much slower speeds.

CNC xPRO V5 GRBL Controller

The xPRO V5(We Recommend) is the most advanced GRBL CNC Controller in the world. Developed by Spark Concepts in USA who have been making GRBL CNC products for many years. It runs off a 32bit processor with over 4x the processing power of most other GRBL controllers. The xPRO V5 is pre-assembled and pre-flashed with the latest GRBL version. We recommend the xPRO V5 as the best controller option available. The stepper drivers are easily suitable for our High Torque Stepper Motors and can even power stronger motors such as Nema34.

Features:
● 32bit processor
● High powered Trinamic 6A Stepper Drivers
● Supports VFD control
● Easy Plug and Play
● SD Card which allows for offline use
● Both Wi-Fi connection & USB connection (user choice)
● This option is the best choice for both a novice starting out, and with people with experience and technical knowledge.

Key Difference:
● Water-Cooled: Better for heavy-duty, continuous tasks with quieter and cooler operation.
● Air-Cooled: Simpler, low-maintenance choice for moderate tasks with easier setup.


Our Suggestion:
● It depends on the application you are using them for.
● If you are milling timber then air cooled will be sufficient.
● If you are milling metals, or are using the spindle for more than 8 hours at one time then water cooled will be recommended.

Free Gift - 10PCS Drill Bits (Optional)

Z Travel Explained

The WorkUltra has two spoilerboard support configurations. One with a travel of 66mm, and a lower one with a travel of 106mm. The reason for the two configurations is that if the machine is always used to cut thin materials, for accuracy reasons it is better to have the work piece as close to the Z-Actuator as possible, so in this case the machine should be setup in the higher 66mm travel configuration.The higher configuration has a Z travel of 66mm, with a 12mm spoiler board, this will reduce the Z travel to 54mm. In this case 54mm is maximum thickness of material that will fit on the machine.To calculate the max cutting depth for a chosen piece of material it is:
● Max Cutting Depth = Z travel – Material Thickness

For instance a setup with a 12mm spoiler board, the max Z travel is 54mm, so when cutting into a material 30mm thick the max cutting depth would be:Max Cutting Depth = 54 – 30 = 24mmThis means with a 30mm piece of material it would not be possible to cut it the whole way through.The max thickness that can be cut the whole way through is half the Z travel. So with a Z travel of 55mm, 27mm is the maximum thickness of material that could be cut the whole way through. And for the lower configuration the maximum thickness that can be cut the whole way through is 47mm.

Z Height

54mm Or 94mm Travel, 27mm Or 47mm Workable depth, with a 12mm spoilerboard. The spoilerboard supports have two height configurations, these are the maximums for each configuration.
