Why is My UCR201 Jog Pendant Not Showing Up In UCCNC?

The UCR201 Jog Pendant requires the user to enable the plugin in the configuration window in UCCNC. If you are running version 1.2037 of UCCNC, you may find that the Jog Pendant does not show up in the configuration window. If this is the case, you simply need to update UCCNC to a newer version which can be found below…

UCCNC Version 1.2049 –

After downloading and installing version 1.2049 of UCCNC, the Jog Pendant should now be visible in the configuration window and you can proceed with the rest of the setup!

Where do I attach the green ground cord on the Stepcraft D-Series machine?

The green ground cord is used to provide a way for any possible static that would build up on the machine to discharge back to earth ground.  The ring terminal on the green ground cable that comes with your machine is attached to one of the screws from the control board mount on the bottom of the machine.  Any of the screws will work just fine.

What tools are required to build a STEPCRAFT CNC machine?


We have a free video from our Assembly Course that explains it:


For USA, CANADA and MEXICO, Please call 203-556-1856 and select ‘support’ during normal business hours (M-F 9am to 5pm) or email anytime day or night and someone will take care of you right away.

If you purchases your system from another country, please contact that dealer that you purchased your system from, or contact (the German headquarters) and someone will be able to help you


With well over 6500 STEPCRAFT systems sold around the world, there stands to reason that a small percentage of customer might have some trouble.  The instructions are very well thought out for any level of builder, but still, you MUST follow them step by step.  Additionally we produced a Assembly Training Course that is a video tutorial outlining every step in the manual. Between the manual and videos, the average customer should not have any trouble.

We find that many customers who you are reading about either do not have the skill set to understand basic assembly terminology or are skipping steps in the assembly process.  Many times a quick call to our support team has the customer up and running quickly.

There are no special tools or skills required to assemble a STEPCRAFT kit, but if you are the type of person who “skims” through manuals and are not detail oriented when assembling something, then you might have the same issues that some people post about.   While it is not a hard build, there are a few items that you must pay attention to due to the precise nature of the machine.

If you take your time and follow the steps in the videos and manual, you will not have any problems building your STEPCRAFT CNC.


On average it takes between 8-10 hours depending on your skill level.  The kits are not hard to assemble and there are no special tools required.  We also have an online video training course that walks you though every step of the assembly process.

How do I tram my Stepcraft CNC system?

The process of tramming your CNC system is an easy, but critical step to getting the most accurate results. By tramming your Z axis, you are insuring that the spindle will not be tilted to one side or the other, creating an unwanted angle to any milled areas. Included below is a short PDF covering the basic procedure of tramming your Stepcraft CNC system. The same concept can be done using a dial indicator or machinist’s square for even greater accuracy.

How do I Test a Faulty Stepper Motor?

When troubleshooting a faulty stepper motor, it is important to be weary of incorrect or shorted wiring. While inspecting your connections and wires may be required, there is a simple process that can save you some time and effort when testing your system’s steppers. Included below is a short PDF that covers the signs of a damaged or shorting stepper motor, and how to quickly diagnose the issue.

How do I connect my Remote Switchable Power Controller?

To connect your remote switchable power controller system, follow the diagram below…

How come my STEPCRAFT CNC kit did not come with lubricant?

There is a very good chance that your kit DID come with lubricant but you skipped past it in the box.  The white container for the lubricant blends well with the white styrofoam from the kit dividers.  There is a round pocket that is specifically designed to hold the lubricant container.  Please look for this.  If you still can not find it, then email

Yes, ALL Machines and most attachments come with a printed manual.  Some newer products or smaller attachments might only come with a PDF manual which you can download by clicking the “DOWNLOADS” tab from the product page on the website

Yes, you c an buy the machine fully assembled, tested and crated.  There is an additional charge of $499. Since the machine is crated, all size D-Series machines must be shipped via a freight company which will incur an additional cost over shipping a KIT via UPS.
