I Yes much confusion but it makes sence now, was wondering why when I put 1600 in pro tune it went rather slow! Super smooth though lol many thanks

Yes 320,000 micro steps per revolution does tend to have that affect . . LOL

Hi all hope every one is doing well, its been a while since I have been on here mainly due to the fact the cnc has made me super busy with what I made it for ( cutting stand up paddle boards)

Any way last week I made my biggest mistake and killed my super expensive router bit by hitting something and bending it a fraction, I nearly cried!

I have a new bit now although of a different type and this one requires spinning the opposite direction. Tbh I have kinda forgotten a lot about how I built it and set it up but just wondering if any one could prompt me with the best way I would go about changing from ccw to cw rotation on the china 2.2kw spindle/vfd.



any for those that are interested this is what I have been cutting the last year.

Many thanks

If you don't want to change any software or vfd settings then just swapping any two of the three wires over going to the spindle will reverse it.

Charlie do you control on/off thru software.? If so then just swap wire going to "For" to "Rev".

Or if you want both forward and reverse options then setup another wire coming from Spindle control relay to the "Rev" and use M4 in your G-code.

cheers guys I guess it would be handy to have booth available I will have to open it up and see if tony wired it like that already

many thanks

I guess if I just use the m4 code it tell me if we wired it for it or not already?

Yes that would be correct If not as Dean has said just change the position of the cable going to the "For" and put it in the "Rev" terminal in the VFD

Yes and it's likely not.! . . . But Charlie be aware that these spindles are not designed to be run in reverse.? They can unscrew the collet running in reverse if the forces are high.
In your case I think you'll be ok but still make sure you really tighten the collet.
