Hello all, well working on the spindle control via Mach3. I have the ESS attached to the C32 board trying to run the G0704 stock circuit board via mach3. I have used the following wiring diagram from CNC4PC.

This is driving me crazy, I think my ports and pins are setup right in Mach3 but not for certain. When I try to run the spindle I get a message saying the pulley RPM is to low. Not sure what this means. I have the pulley set for 1 at min 100 max 2250. I have tried to test the voltage from the 0-10v analog output port 1-14pin, but get nothing! This tells me mach3 does not see it. The relay #1 is port #1 Pin #16. The directions for the C6 or the C32 says to configure the ESS for the setup but dont know how to do that. Anyone have any ideas.

A little tinkering and following some printed directions got the spindle up and running via mach3. I will need some fine tuning but that will have to wait a few days.

want to clue me in what you did? I am at this point and get nothing but .4vdc (which is constant) unless I check step direction low active, then I get 10vdc. I can not get any voltage (other than the .4) to show, so I must have the settings wrong.....

Hello It's been a long time since I have messed with this process but what I did was this. I followed the directions off of the CNC4PC website on the C32 board to the T. I ran the spindle up to the max RPM and put a voltage meter on the C32 board on the analog output. I then fine tuned the trim pot on the C32 board to get the 10volt output while the spindle was up to the max RPM. It was a very tedious job to do but I managed to do it. You will not get the RPM on the G0704 to match the RPM on the Mach3 screen. The reason for this is, the disk on the stock mill has to many holes in it so it thinks it is going faster than it is. I still have the RPM readout on the stock mill so the RPM that I set in Mach3 does not matter to me because the true RPM that I am reading is from the RPM tack on the mill. As far as how I have the spindle set up in Mach3, you will have to call me for that and I will tell you what settings I have. I tried to message you but you did not have room for a private message. I have my mill torn apart right now for some retrofit stuff but hope to have it up and running in a month or two. I don't know as much as some but have had a GREAT mentor on the forum who is very smart on these mills.
