Where can I download UCCNC?
UCCNC is the machine control software that moves your STEPCRAFT machine and interprets G-Code. In order to use your STEPCRAFT machine, you will need the UCCNC software as well as the STEPCRAFT machine specific profiles. You can download and install both from the STEPCRAFT Multi-Installer that comes on your orange USB flash drive, or download here. STEPCRAFT will always have the latest compatible version of UCCNC included in the Multi-Installer. If you are looking for the newest released version of UCCNC, you can download here (note: UCCNC may release versions newer than those included on the STEPCRAFT Multi-Installer. These versions may not have been fully tested and may cause some bugs/issues with your machine. It is reccomended to use the version of UCCNC included on the STEPCRAFT Multi-Installer).
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.
