CNC mach spindle not spinning

[JAZZCNC]

You are so rite Clive. I tried again this afternoon but without success.

What format are you trying to send.? also if the file size is too large they won't send. Better to use Jpeg and try to keep them below 2mb.

Hey
Can someone help me to learn the Cnc machine High-z S400 and the software Construcam 3D?

[Bernard]

Thanks Jazz. Will reduce size

Here are the attachments. Hope it come thru ok! Thanks

Hi Bernard, Ok well, to be honest, and as expected, I've got a feeling this controller can not control the spindle speed from mach3. For Mach3 to control the spindle speed then it must have a spindle card installed or the breakout board which can provide a speed reference voltage. However to be sure we will need to look inside the controller at the boards to see what you have. So if you can take the lid off and get some good pics it will help.

However, even if it doesn't have speed reference voltage it's still possible to control the ON/OFF from Mach3 which is still very handy.

Hi Jazz, I will get some pics from the inside of the controller and post it, hopefully today. Thanks for your help, much appreciated

Hi Jazz, here are the pics of the inside of the controller. Please check to see if the spindle card is there. Don't have a clue what it looks like

As the spindle is 220v (which is stated on top of spindle), can we connect 220v direct to the spindle externally, bi-passing the control box, with a separate speed controller. I can then power the spindle before cutting, independent of Mach 3 controls of the spindle. Cheers, Bernard



Hi Jazz, more pics. Spindle is AC 220v. From pic it has four pins. Can I do what I suggested above, to by pass the controller and power the spindle with 220v AC?
The manual switch on the controller box will not power the spindle

Another picture of internal wiring to the spindle connector outside the box



Hi Jazz, here is the link to the 'User guide for CNC 3040. Hope this will help. I followed this guide.

Edit: Deleted just noticed the VFD control on the front

Bernard, for this limited control - you should have this already - the front panel "Spindle Mode" positioned to Manual, then use the 'RUN' and rotary control on the front panel to control speed. Are you suggesting that this doesn't work?

Re. connecting the spindle to 220VAC directly, or through a speed controller - it's *probably* a three-phase spindle and so you need a 3-phase inverter with variable frequency drive give variable speed. If you follow the ribbon from the front panel control on the white box to a larger control board in the enclosure that will be the integral 3 phase inverter - so you already have this.

The board at the top...

I'd ask first of all if you can get the manual control to work - just so that we know where we're starting from.

Hi Doddy, Tried the manual toggle but somehow it does not work. Used a multimeter and checked the spindle coils. They seem to be ok
