A CNC Mach3 User's Experience with XHC MK4 Card

As a CNC machining enthusiast, I've had my fair share of experiences with various cards and software. Recently, I decided to try out the XHC MK4 card with Mach3 and was excited to see how it would perform. In this article, I'll share my experience with the XHC MK4 card, highlighting its features, challenges, and overall performance.

One of the main reasons I chose the XHC MK4 card is its compatibility with Mach3. As a long-time user of Mach3, I was eager to see how well it would work with this new card. Unfortunately, my experience with the card was marred by a significant amount of backlash – approximately 0.1 mm, which is far too much for precise CNC machining.

Another issue I encountered was the lack of backlash compensation, which made it difficult for me to achieve accurate cuts. This was a major concern for me, as I rely heavily on precision in my work. In hindsight, I wish I had done more research on the card's capabilities before purchasing it.

On the positive side, I appreciated the ease of installation and configuration of the XHC MK4 card with Mach3. The plugin files were straightforward to install, and the card recognized the software quickly. However, I did experience some issues during the initial setup process, which may have been due to a problem with the instructions provided.

After reinstalling the software and reconfiguring the plugin files, I was able to get the XHC MK4 card working smoothly with Mach3. The movement was smooth and precise, but I still encountered some issues with switching between metric and imperial units.

In my experience, switching units can be a bit of a challenge with the XHC MK4 card. While it's possible to switch between units using the MDI command G21, this process is not always seamless. It would be nice if Mach3 could stay in metric mode by default, eliminating the need for frequent unit conversions.

In conclusion, my experience with the XHC MK4 card was mixed. While it has some positive features, such as ease of installation and smooth movement, it also has some significant drawbacks, including a lack of backlash compensation and issues with unit switching. If you're considering purchasing this card, I recommend doing your research thoroughly to ensure that it meets your specific needs.
