CMP-COLOR UCCNC SUITE
FOR MANUAL TOOL CHANGE AND 4th ROTARY AXIS

Why do we need a better Post Processor ?

While Autodesk Fusion and UCCNC are both excellent software packages that are relatively easy to learn, the connection between Fusion and UCCNC relies on a post processor that is not necessarily optimized in its original form. Many useful features remain hidden, and even something as simple as a manual tool change with tool probing initially requires solid programming knowledge to edit UCCNC macros and achieve a reliable workflow.

Many users give up when faced with this unnecessary level of complexity. To eliminate these issues, I felt it was worthwhile to develop a post processor specifically designed for UCCNC users with little or no programming experience. There are no M6 or M31 macros to edit anymore—everything is handled directly by the post processor.

Based on the assumption that the user performs manual tool changes and has a permanently mounted fixed tool probe on the machine table, the post processor allows all the required parameters to be configured easily:

- Manual tool change position (X, Y and Z)

- Fixed tool probe position (X and Y)

- Tool probing parameters (fast feed rate, slow feed rate, probing distance, retract distance, and probe height)

The G53 safe retract command, especially when a rotary axis is used, often causes unexpected issues. To solve this, I added a configurable G53 safe retract height to the post processor, eliminating the problems commonly encountered in this situation.

I also added support for a 4th rotary axis, including the ability to define custom spindle safe retract coordinates, as well as optional pauses before and after each indexed rotation. This allows the operator to remove and replace a support block beneath the workpiece.

When machining flexible materials, it is common practice to place a support block under the workpiece to prevent deformation and reduce vibration during machining.

The post processor interface has been completely redesigned, making it far more intuitive and better suited to UCCNC:

These settings are then written into the G-code as a small block of approximately fifteen lines and are used by the custom macros we have developed. The result is a UCCNC environment that is significantly easier to use, safer, and completely transparent to the operator.

Installation takes about 15 minutes: simply copy the supplied files to the locations specified in the CMP-COLOR UCCNC Suite User Manual. Once the installation is complete, no further configuration is required, as all the necessary parameters are automatically transferred through the G-code.

The section highlighted in red contains the code responsible for managing the CMP Suite parameters.
These parameters are automatically generated in the machining G-code, then read and applied transparently during execution.
No user intervention is required.

CMP-COLOR UCCNC Suite File Overview

 The CMP-COLOR UCCNC Suite includes the following files:
The macros required for proper operation.
The installer, which acts as a patcher.
The original post processor, which is patched to complete the CMP-COLOR UCCNC Suite installation.

The CMP post processor is based on the official post processor, which is protected by copyright and owned by Autodesk and UCCNC. As a result, I cannot sell the original post processor itself.

However, I am fully entitled to distribute and sell a patch that adds new functionality to the original post processor. For this reason, the CMP-COLOR UCCNC Suite is distributed as a patch that enhances the original post processor, rather than as a modified version of the original file. For convenience, the original Autodesk/UCCNC post processor, which is publicly available for download from the Autodesk website, is included with the CMP-COLOR UCCNC Suite.

Using the CMP-COLOR UCCNC Suite

Using the CMP-COLOR UCCNC Suite is extremely straightforward because, from the user's perspective, nothing changes:

After starting UCCNC, simply perform the homing cycle, install the cutting tool, measure the tool length, set the workpiece offsets, and load the G-code generated by Autodesk Fusion using the CMP-COLOR post processor. You are then ready to start machining. Everything else is handled automatically, making the entire process transparent, simple, and reliable for the user.

Nothing changes… or does it?

Actually, it changes a lot. You no longer need to edit macros, and the configurable G53 safe retract height allows you to use G53 reliably and without the issues commonly encountered with the original post processor.

The system is robust, easy to configure, and simple to fine-tune. It also provides full support for a 4th rotary axis, including both indexed and continuous machining, with configurable pauses and a safe spindle position during indexed rotations.

Finally, clear on-screen messages guide the operator through each required action, making the entire machining process more intuitive and user-friendly.

Pricing

We have chosen a competitive price of €64.50 for the CMP-COLOR UCCNC Suite. Once your PayPal payment has been received, you will receive, via WeTransfer, all the files required for installation, along with the User Manual, within 24 hours.

The CMP-COLOR UCCNC Suite has been tested with Autodesk Fusion version 2.0.2704.1.15 and UCCNC version 1.2115
