Software Troubleshooting

Why won’t the UCCNC installer complete when running the Stepcraft Multi-installer?

 

The most common cause that prevents the UCCNC installation from completing is due to the lack of Microsoft’s .NET Framework being installed. To do so, simply navigate to your Control Panel and select Programs. From there select the “Turn Windows Features on and off” option. Check the box for Microsoft .NET 3.5. Once your .NET framework is installed, continue with a fresh installation of UCCNC using the Stepcraft Multi-installer provided with your Stepcraft CNC system.

The most common cause for UCCNC running sluggish or slow, to the point where it is almost unusable, is because Windows had recently automatically installed an update in the background.  This is most common when using Windows 10.  CNC Drive, the makers of UCCNC software are very good with addressing these issues, however sometimes they have to wait until they even know there is an issue, which is usually when users notice the problem and contact CNCDrive or post online.  If this happens to you before a UCCCNC update is available, then the fix is to uninstall the most recent Windows update (or updates).  The following video shows you how to do this.

Why is the Yellow dot not in the location I set on my work piece in UCCNC?

In the live display window in UCCNC it shows you your project file as well as the location of the tool in real time.  The tool is represented by a Yellow Dot on the screen.  If you setup a job with the XY datum in the center of your job, then Yellow dot should be in the center of the screen in that window before you start running the job.

This is how the yellow dot should look on a job where you set the XY Datum to be in the center of the work piece.

 

If the dot is NOT in the where you set it in your CAD/CAM file, then it is most likely because you did not ZERO X AND Y once you positioned the end mill (Spindle) at the starting location.  Please use the following steps when you setup a job to ensure that your yellow dot is always where you want it before you run a job:

This is what it might look like if you have not zeroed your machine. The Yellow dot will be outside of the work piece.

 

To ensure that your job is always setup properly, please follow these steps:

  1. Load your work piece onto the CNC and secure it
  2. Home your CNC machine (Press Home All on UCCNC)
  3. Manually move the end mill (spindle) to the location that you want to start the job on your work piece
  4. PRESS THE HOME BUTTON FOR Y AND X – this will reset the digital read out (DRO) to 0.00 for each.
  5. Load your GCode file – when you do you should notice that the yellow dot is where you set it up in your CAM file (lower left, center, etc)
  6. Set your Z Zero manually by lowering it to touch the material surface or machine bed (to match how your setup your CAM file) OR use a Tool Length Sensor
  7. Run your job!

 

How come my circles are not perfectly round?

Then you are machining circles on a CNC and your circles are not coming out perfectly round, it is commonly caused because there is some backlash developing on the machine.  Backlash is a tiny amount of play that appears over time and is noticed when a drive changes direction.

When running in a positive direction, the gears/lead screw are engaged with the lead screw nut on the gantry, but when the stepper motor reverses direction there is a tiny space between the lead screw and the lead screw nut that has to be made up before there is positive engagement in that direction.  After many, many hours of use or if your machine is not properly maintained and lubricated, then this backlash can develop.

If this is happening to you, please download this document: Stepcraft UCCNC Backlash Compensation.

This will show you how to setup backlash compensation in UCCNC so that you can “dial” out any backlash and go back to having perfect circles again.

What post processor do I use for Vectric programs (Aspire, VCarve, Cut 2d, Cut 3D, PhotoVCarve)?

 

NOTE: These post processors will work for BOTH UCCNC and WIN-PC NC

From the dropdown list in Vectric programs, you will look for the following

If you have an Automatic Tool Changer: Stepcraft UCCNC ATC Arcs (mm) (*.txt)

If you do not have an Automatic Tool Changer: Stepcraft UCCNC Arcs (mm) (*.txt)

If you have an older version of Vectric software and the STEPCRAFT post processors are NOT in the dropdown list, please use the following:

 

If you have an Automatic Tool Changer: Mach2/3 ATC Arcs (mm) (*.txt)

If you do not have an Automatic Tool Changer: Mach2/3 Arcs (mm) (*.txt)

Sometimes when you start UCCNC you will get the “Select the motion controller device from the list” message box that pops up. This is either happening because your UC100 interface or USB cable is unplugged or the device driver did not properly install. This video will show you how to fix this.

What does “The current job workspace is out of the set software limits” error window mean?

 

This error happens when your design is larger than the allowable work area on the CNC machine.  Every machine has its own specific software profile that you install with UCCNC.  This software profile tells UCCNC what the available work area size is on your machine.  The main reason for this is to protect your machine from crashing into itself if you run a job that is larger than the machine’s capabilities. Think of the “software limits” as invisible limit switches. When you load a job into UCCNC, it looks at the G-Code automatically and compares the XYZ dimensions of your file against the software profile to make sure that the job can fit on your machine.  If the settings in your file are larger than the work area, then you will get this error window.

Sometimes, if your job is NOT larger than the work area size for your machine and you get this error, you can reposition your work piece so when you zero X and Y that you fall within the work area.  For example.  Say your machine has a work area limits that are set to 420 mm on Y and 300 mm on X and you are trying to run a job that is 380 mm long x 280 mm wide.  This job should work with no problem, however if you have the work piece positioned more than 20mm from the left side of the machines work area limit or 40 mm away from the front of the machine, and you have zeroed UCCNC in that position,  then you will get this error when you start the job because it adds the job size to the position where you have X and Y zeroed and if that number is greater than 420 on Y or 300 on X it triggers the error.

It is important to take into account your “safe Z height” when encountering this error. If your safe Z height causes the Z-Axis to travel past the limits of the machine you will get this error. This is very common when working with thicker materials or long end mills. You can adjust your safe Z height in two places…

1.) In your CAD/CAM program. If you are using Vectric it will be under “Material Setup”.

2.) In UCCNC –> CONFIGURATION –> GENERAL SETTINGS. About half way down on the right side you have your “Safe Z height (Units). You can lower this number for more room.

The two values do stack, so if you are still having trouble try lowering both.

Another common cause for the error is to verify where your XY Datum is located in your design file.  Many times a job might have been set with a XY datum of the lower left corner but the operator sets the machine up as if the XY Datum is in the center.  This will, in most cases, cause the error because that zero position added to the jobs work size will exceed the software limits of the profile in UCCNC.

On rare occasions when you click the UCCNC installer, it will seem like it is going to run but then nothing happens.  In order for UCCNC to properly install, it requires the .Net 2.0 framework and some Windows 10 machines, it is turned off by default.  You can turn this on easily by following this video.

My machine is in reset mode and I can not get it to reset, how can I fix this?

If your machine will not come out of reset mode, there are three things to check:

  1. Make sure that UCCNC is not running in Demo Mode. If UCCNC is running in demo mode, the software will not reset.
  2. Ensure that the emergency stop button is not press in on the front of the machine. You can disengage it by simply twisting it to the right slightly and it should pop out.  If it is already out, then you can move on to #2.
  3. Check the Y Axis limit switch wires on the back of the machine.  Sometimes these wires can be accidentally knocked out and become disconnected.  Be sure both wires are plugged in correctly.
  4. Click on the DIAGNOSTICS tab in UCCNC.  Check to see if any of the limit switch lights are on in the I/O Function Monitor. (Please see the video below starting at 1:36)

 

How do I Recover My UCCNC License File?

If you have misplaced or lost your UCCNC license key file, the process of recovering it is fast and easy. The serial number located on one side of your UC100 corresponds to your hard-coded license key, as shown below. Simply contact our support team and provide them with this serial number, and you will receive your recovered license file as an email attachment.

Can I use Fusion 360 from Autodesk with my STEPCRAFT CNC?

Yes, you can use Fusion 360 with STEPCRAFT.  There is a post processor that you can download for the CAM portion of Fusion 360 by going to http://cam.autodesk.com/posts/.  STEPCRAFT (www.stepcraft.us) includes a free one year subscription to Fusion 360 when you purchase a CNC system.

Fusion 360 is a very powerful program that can greatly expand the capabilities of what you can do with a STEPCRAFT (or any CNC for that matter).

 

 

Can I use a Mac with a STEPCRAFT CNC?

Yes! While the UCCNC and Vectric Software both run on Windows platforms, you can use a MAC as long as you run Parallels software which allows you to install Windows on your Mac.  You can not run UCCNC or Vectric natively on a Mac (without Parallels).  If you use Fusion 360 for CAD/CAM, then you can install that natively as they have a Mac version of that software.  However, UCCNC will still need Parallels with Windows.

NOTE: Since a Mac computer is typically much more expensive than a Windows system, and the fact that UCCNC does not need a powerful computer, we recommend using your Mac for the design work and then getting an inexpensive or refurbished computer (desktop or laptop) to use to run the CNC, since the area around the CNC can potentially have dust and chips that might get on or near the computer.
