Mounting the Machine
The overall dimensions of the H-Series with filament cabinet and build enclosure are:
It can weigh up to 70kgs (150lbs)
Any sturdy work surface will suffice as a benchtop to mount the H-Series machine. You can find the mounting hole dimensions here, and generally use the bolts that the machine were shipped with. If longer bolts are required, the thread is M8x1.25mm. See the attachment for specific mounting hole locations, or to print a template.
One recommended bench is the 60x36 U-Line Packing Table. However, for the build enclosure to fit bottom-down underneath the bench, the lower shelf will require modification (the enclosure will fit on its back underneath in the standard configuration).
For a custom bench, the two files below show the workbench design that we used for the H4 prototype machines. It is a simple design with aluminum extrusion corners, ½” and ¾” black melamine panels, and penetrations for mounting screws and maintenance access. It is a good design if you prefer woodworking tools and aluminum extrusion. We used this same design, but added a ¼” steel plate to the top for added stiffness. A second design made with welded tubing is also shown below. This is our preferred design for the H4 machines as it is stiffer and has lower material cost. If you're not a welder, any local welding shop will be able to fabricate this quickly for you.
Note, the depth of both of these designs is the minimum required to allow use of the build enclosure. If your machine will be placed against a wall, you will want to increase the distance from the back bolt hole toward the back side.
Power and Air
Any 15A grounded circuit will sufficiently power the H4, which will never exceed 10A current draw. GFCI is not required.
Dry, compressed air is recommended for milling operations (air cools the spindles and removes chips during milling). The air supply should be at least 2CFM at 60psi. For comfort during operation, we recommend a compressor below 65 decibels (option, option)
