Title: Annoying issue with my cnc router
Post by: Sambonnie on June 11, 2022, 10:36:31 AM

Good Day All,

Sorry If this is in thr wrong section.

I have a home built CNC router running mach 3. Was built in 2011.

Long story short.... Left machine running a finishing pass on some vacuum forming molds came back once finished and the spindle was sitting very randomly spinning in a none natrul way. https://youtube.com/shorts/OUIfTT_EAKI (https://youtube.com/shorts/OUIfTT_EAKI)

Parts I have changed thus far....

A new pmdx 126 and 107 board have been fitted.

If any one can shed any light onto this i will be greatful as you all know, Its an expesive table if its not cutting.

Thank you in advance

regards Tom

 What make is your VFD? if its a HaunYang then you might try resetting to factory settings  and reset everything.

Hi,
rather than just scatter gun new parts here and there you might try some things to narrow the field down.

For instance disconnect the VFD from Mach altogether and use a 9V battery to apply an analog voltage that would ordinarily be supplied by Mach and your BoB.
That would at least confirm if the VFD and/or motor are OK.
