I am rebuilding a K2 CNC controller using the acorn board. This controller uses Gecko G320X servo drives. The schematic given for these drives only show the drives connecting to the DB25 connector, can the screw terminal connector be used instead?
no. use the DB25. follow this schematic for Acorn to G320

I hate to hijack this thread, but I wanted to ask for more information as it relates to the G320 drives that might be able to help people in the future. I hope that Mr. cnckeith here can support what I'm talking about here. This is the thread that is listed at the top when you search G320 Gecko.
The DB25 connector, while it natively communicates in 5v signals, is it required for communication with the geckodrive?
I have the G320 wired in the following manner:
Terminal 10 (DIR) connected to the Direction screw terminal
Terminal 11 (Step) connected to the Step screw terminal
Terminal 12 (COM) connected to a relay that provides +5VDC on NoFaultOut
I have run some stress tests on the machine and I have not yet let the smoke out.
hi, i haven't worked with the 320 drives in a long while.
when we last tested with them they worked best for us on the DB25.
I invite you to make a build thread, here is how.
viewtopic.php?f=60&t=6928
Creating a "build thread" on centroidcncforum.com offers several advantages for a customer, particularly those working on CNC projects with Centroid products like the Acorn, AcornSix, USB-BOB,Hickory, Oak, or Allin1DC controllers. Based on the forum’s structure and guidance, here’s why it’s beneficial:
Organized Documentation: A build thread consolidates all information, questions, and progress about your CNC machine project into a single, cohesive post. Instead of scattering details across multiple threads or emails, everything—from initial setup to troubleshooting—is in one place. This makes it easier for you and us to track your progress and refer back to earlier steps or solutions.
Timely CNC Technical Assistance: The forum’s posting guidelines highlight that a build thread is "an effective way to receive timely technical support." By keeping everything centralized, experts like moderators or other power users can quickly spot where you’re at and offer targeted solutions, especially since Centroid staff actively monitor the forum.
Resource Centralization: The forum encourages linking to a single photo album, YouTube channel, or Google Drive folder within your thread. This keeps all visuals and files in one spot, making it easier for you to manage resources and for others to follow along without sifting through attachments spread across multiple posts.
Showcasing and Learning: A build thread lets you document your journey start-to-finish, which can be satisfying and educational. You can share successes (like completed retrofits, featured in the "Success Stories" section) and learn from feedback. It also inspires others while allowing you to refine your approach based on community input.
Better Support from the CNC Community: The forum emphasizes that a build thread helps others understand your project comprehensively. When you need help, responders (including Centroid staff and experienced users) can see the full context—photos, specs, and prior issues—without you having to repeat yourself. This leads to faster, more accurate advice, as the community doesn’t have to dig through disjointed posts to piece together your situation.
In short, a build thread streamlines communication, enhances support quality, and creates a valuable record—saving you time while maximizing your CNC project's potential.
