I have a spindle which I absolutely love.Once you use a spindle, you’ll never go back to a router. It has one slightly annoying issue and that is the protracted time it takes to spin the spindle down to a complete stop after a carve/cut or tool change. It can be 45+ seconds. If you’re using Vectric…

I have spent a considerable amount of time chasing this issue. At the top of this thread, I proposed a work around to alleviate the issue by modifying the post processor file. I’ve studied this in detail and thanks to a fellow member, Martin, who directed me to some information in the VFD manual, I’…

Great post Tom - this kind of conversation is what the forum is all about. Thanks for your time in problem solving and posting the fix. :+1:

Did you contact onefinity to update their " EM60" configuration settings in their next update to correct this?

Hey Tom @tjp52 , [image] tjp52: It’s easy to test the change to see if it’s working as expected. Just select the MDI tab and enter ‘M3 S10000’ and press ►. This will accelerate the spindle to 10,000rpm. Check your VFD and your buildbotics displays to verify the speeds are the same. Press ■ and t…

No, I didn’t contact one-finity…only reason is that the spindle is EM60 and my thinking was that they should connect with onefinity. I did convey the information. The other thing is, I really am not sure who’s responsible for the controller software…is it Buildbotics (the manufacturer of the control…

Hey Tom @tjp52 , [image] tjp52: is it Buildbotics (the manufacturer of the controller) or is it Onefinity (who I’m led to believe has customized the controller software). The Onefinity CNC Controller is a software and hardware fork of the Buildbotics.com CNC Controller and is not produced by …

Ok. Thanks for the clarification. I’ll pass the info along to onefinity and see what they do with it.

Edit: added 1.4.0 Alpha 3 (Macros update) Noted, We’ll see if we can get it in the next firmware release.

Not a puzzle at all. The buildbotics controller is a “translator” and “traffic cop” that reads the G-Code program then translates what it reads into commands that tell the VFD what to do with the spindle and to tell the stepper motors (X,Y & Z) how many steps to move and in which direction. The man…

Hey all, the Modbus data structure and a complete list of Modbus functions that a VFD supports should be listed in the Modbus/RS-485 serial communication chapter in its VFD manual. Usually a VFD supports much more functions than an average CNC Controller will in fact use (remember that a VFD works…
