Understanding the Homing Procedure

Whenever you open UCCNC, the very first movement you should make with your machine is "Home All". On a STEPCRAFT, the homing procedure begins with the Z-Axis, then the X-Axis and finally the Y-Axis. Each axis will run towards its limit switch until it engages the switch, then will run the opposite way until the switch disengages. Once all three axis have hit their limit switch, your machine is now ready to travel the full length of each axis!

This is known as a reference movement for the machine. Without this reference movement, the machine has no idea where it is along its axis and may not travel the full length back and forth. If your machine is stopping short of the full length of travel and you aren't noticing any binding, make sure to "Home All" and try running again.

One important thing to note is that if any axis ever travels in the opposite direction of its limit switch when homing, check to make sure a limit switch is not engaged somewhere on the machine. All of the limit switches are on the same circuit, so if you tried to home your machine and the Y-Axis limit switch was pressed, the Z-Axis would travel in the OPPOSITE direction. This happens because the machine is going through the stage of homing when it backs away from the switch until it disengages. Because the Y-Axis switch was pressed, the Z-Axis will infinitely try to move away but it will never disengage.

The Oscillating Tangential Knife requires no special software outside of the standard CAD/CAM program used to design and create toolpaths. Cut2D, VCarve Desktop and VCarve Pro are all compatible with the OTK-3. As of May 2019, the only "special" software needed to run the knife is the free version 1.2110 of UCCNC.

Securing your workpiece for use with the OTK-3 may require use of a vacuum table or sticky table, as materials such as hard foam, cardboard, leather, cork and carpet can be tough to hold with traditional clamping methods.

How can I reset my Stepcraft UCCNC installation?

Can't seem to solve a strange bug or error? Can't find a fix here? Mismatched or changed profile settings are a very common cause, but what if you cannot locate the setting that is giving you these issues?

A fresh installation will take care of making sure your profile settings match the default ones and make sure that you are not going in circles when troubleshooting UCCNC. This short video will walk you through each step required to not only remove any trace elements of your old installation, but also covers how to re-install your profiles to reduce downtime and get your machine back up and running.

Your E-Stop could be active. Check to make sure the E-Stop in the front face of your machine is not engaged. Also, the US 110 volt edition of Q-Series machine has an additional spindle safety circuit to check - Make sure your 110 volt plug from the back of the machine is connected to a live power source, or, your spindle safety override switch (located on the top of the machine) is engaged.

The HF-500 can support up to 8mm ER11 collets.  The most popular in North America are 1/8” and 1/4”, but they have collets that range from 1mm to 8mm that will work.   The ER11 is an industry standard that determines the overall collet size.  ER11, ER16, ER20, ER25 are all common sizes.   But the HF 500 and our Tool Changer tool holders for the MM-1000 are both designed for the ER11.
