Acorn CNC randomly changed tool heights. < i doubt it :-)>

[myths420]

Anyone ever run into this ? Been running fine the last week went to mill another part today and bit just jammed into material. Replaced but and went to recalibrate the offset and noticed the the previous one changed by almost half an inch.

nope, cnc12 does not do this.

you probably switched WCS positions or your g code program did it for you.

or if you are using open loop steppers they lost position.

either way, i'd need to know a whole lot more about the machine to help you figure it out.

Ty not sure just know the tool offset was definitely different than I set it to. This bit I have offset to around 1.4 as it's a longer but for boring holes but was set at .9 I noticed after crash. No idea how it could of gotten changed as I've not even had to calibrate any new tools sense I last used this tool in a run.

Even if it switched wcs or something else I don't see how tool height would be changed in tool library.

Maybe crashed and rolled back some old settings? Only thing I can think of. Other tools looked good but going to redo them just to be on the safe side now.

did you use "restore report"?

please post a fresh report.zip


and information about your machine otherwise we are all just guessing.

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 and frustration while maximizing the forum’s collaborative potential.

ty ill work on that when i get a chance. honestly not sure how machine build, drives, ect have anything to do with software related issues though. maybe im just encountering all the issues no one has ever had before haha. i still have to zero part twice so acorn software believes me that zero is zero XD.

there are about 20 ways to set a WCS position and Tool offsets, please show (with video) or describe your work flow otherwise its really hard to help.
