The Stepcraft-2 420 CNC desktop system is greater than only a one trick pony. The system is designed to just accept an entire vary of further attachments for doing precision operations in quite a lot of methods. I simply tried out the Drag Knife attachment and I’ve to say it really works like a allure.
Eradicating the ability spindle and changing it with the drag knife attachment is as straightforward as loosing and tightening a single screw. The attachment has a nylon finish cap with a gap within the heart that homes the very fantastic drag knife. This knife is supported by a small swivel bearing for very clean and exact operation.It merely slides into place and is held by the bearing.
(Above) Right here’s the UCCNC program dashboard with the “MAN” drag knife device path preview within the higher left nook.
To function the system as a vinyl cutter, all you need to do is setup the UCCNC drive management program similar to you’d to run an finish mill. You create the job with a program that produces the required G-code, (I used V-Carve Professional), and enter the correct dimensions and setting for the job. For the reason that attachment is spring loaded, this requires a minimize depth of about 2 to 3mm (1/8 inch), so when the knife is slicing the CNC lowers the device barely to maintain it underneath spring pressure. You enter the g-code as you’d for all jobs, then zero all of the axis and enter the brand new job zero place. Subsequent the Z axis is about so the knife simply touches the highest of your vinyl materials.
Prior to installing the attachment within the device holder, you first should set the knife minimize depth and that is simply finished with the highest indicator dial. Set up the knife in the long run of the attachment, and regulate the dial so the blade simply barely protrudes from the plastic finish cap. You possibly can verify the depth of minimize by pushing the attachment gently on high of a bit of check vinyl and drag it. Examine the vinyl and see if it has been minimize. If the knife cuts all through the paper backing, you need to retract the knife for a shallower minimize. When correctly adjusted the drag knife will cleanly minimize by the vinyl however will solely crease the paper backing.
To zero out the Z-axis I moved the cutter over the center of the check materials and used a bit of paper whereas reducing drag knife manually till it simply touched the paper.
Once I ran the job cycle, it took lower than a minute to finish the job. I then used a passion knife to “weed” away the waster materials leaving my letters cleanly minimize and hooked up to the backing paper.
For those who ever needed a customized vinyl slicing machine, the Stepcraft CNC desktop system does an important job for any measurement letters or designs you care to make, (inside the limits of the dimensions CNC system you will have. Give it a attempt, you may make all types of customized airplane markings, signage, decals, and many others. Your creativeness is your solely restrict.
To use the brand new vinyl letters to you mannequin, all you need to do is use a strip of tape to carry them off the backing paper and place them on the mannequin.
Right here the “MAN” graphics have been utilized to the Sonic mannequin. Appropriate vinyl stick-on materials is offered on-line on Amazon and craft shops like Michaels.
