  • Z Axis travel

    To clarify the Z Travel, this is not the max cutting depth or the travel range of the actuator. Z travel is the distance downwards it can travel before hitting the spoiler board supports.

    The SharpCNC 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 = 24mm

    This 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

    Software Options

     

    Spindle Milling/Routing

    For 3 axis CNC milling there are several free and paid software packages you can use to get your SharpCNC running. If you are new to CNCs that's cool too. We all need to start somewhere.

     

    To make things easy and get you setup quickly, we recommend using Easel CNC, Easel is a web based GRBL controller that makes getting started extremely simple.

    You can start using Easel after creating an account by clicking HERE

     

    Laser Engraving

    For laser engraving / Plasma cutting we recommended to use LaserGRBL or T2 Laser.

     

    LaserGRBL is completely FREE and can be downloaded from HERE

    T2 Laser is available at a very reasonable price from HERE

  • Kit details / components / handy info

    Below is a list of components that are included in the various options we have with our kits.

     

    Included in all SharpCNC purchases is a welcome CD with build/wiring instructions and some handy software options. This will be sent to you via email. 

     

    Frame kit

     

    The kit includes all mounting hardware, plates and extrusions required to assemble the frame.

     

    NOTE: We carefully adjust your stepper drivers to suit your motors prior to shipping please be aware of making any changes to these settings not to overdrive the motors.

     

    The specifications of the stepper motors are as follows:

     

    179oz/in

    Specification Value

    Our supplied electronics

     

    Included with our controller:

    • 4 x 4 core shielded Stepper cables with direct plug in to the steppers
    • 3 x 2 core shielded limit switch cables designed for a single limit switch per axis.
    • 3 x limit switches with mounting brackets.
    • 2 x Nylon cable drag chains (3 with a 1500x1500mm kit)
    • 4 x TB6600 stepper drivers
    • 1 x Arduino nano and screw shield preloaded with GRBL 0.9j
    • Dupont connectors for easy screw-in connection
    • DC-DC regulator preset to 12V for powering the Arduino (you may need to check your voltage output to ensure it is near 12V DC, the potentiometer may change during transit)
    • 5V single channel relay module (for switching a plasma torch trigger if required)
    • 24V 16A Meanwell Power supply with prewired DC leads. The DC-DC converter is presoldered in line with a set of leads to power the controller.

     

    IMPORTANT NOTE: We do not supply any of the 240v wiring for the PSU. Electrical safety regulations in Australia require that all 240v work be carried out by a licensed electrician, as such we discourage DIY wiring of the 240v wires. Any DIY work done on the 240V side will void any warranties on the entire kit.

     

    Spindle Add-on

     

    Our 1.5kw Spindle + VFD option accepts ER11 collets only. The spindle is Air cooled for easy installation and maintenance.

    The 1.5kw spindle is actually a 3 phase spindle for extremely quiet and vibration free operation, Typically we ship either a 1.5kw or 2.2kw VFD (Depending on availability) to drive these spindles. The VFDs will accept either a single phase 240v or 3 phase input depending on what you have available.

    The diameter of this spindle is 65mm.

     

    IMPORTANT NOTE: We do not supply any of the high voltage AC wiring for the VFD or spindle. Electrical safety regulations in Australia require that all 240v / 3 phase work be carried out by a licensed electrician, as such we discourage DIY wiring of any high voltage wires. Any DIY work done on the high voltage side will void any warranties on the entire kit.
