    I have the index turned on, to the right port and pin, board is set to low and open collector and have tried ttl also but mach 3 is not interpreting the signal correctly, I have spindle sync on and spindle averaging too.

    Help please?

    Count me among the folks who would like to help, but don't know enough about the boards.

    What it sounds like to me is either a real intermittent connection or something that makes it not work as well as it should. I'm not familiar with what C3 board or D4GS is, but a quick search showed me a C3 Index Pulse board from CNC4PC for motor control, and that sounds like what you're doing. Is that what you mean? On page 6, the manual talks about needing an external pull-up resistor. That could do what you're seeing, so is it configured?

    It would help me if you could tell more about those cards, what they are, maybe link to the user manuals.

    OK, I got it figured out, Arturo had a few suggestions but I am not sure they work with Mach3 or 4 at all, they just keep a record of what works for different users who figure out the problems. The Mach forum was totally useless, alot of people have posted these problems and no one from ArtSoft ever replied.
    I spent about 30 hours going thru the software/drivers that came with the ESS boards, and Mach3, numerous combinations, kept a real good record on what I did and how it failed. I did figure it out eventually.

    I now know the spindle sync and such in Mach3 Mill does not work so give that up.(they should not even put it in if it does not work)
    To get the C3 board to work accurately and reliably with Mach3 Mill, using the ESS with the C10 boards you have to have 2 slots on the timing disc, 180 degrees apart, use the index not the timing in ports and pins then set your prescale in the ESS configuration software to 2, then you will get very accurate RPM's and then you can run the calibrate spindle and it will get within 40+- rpms thru your rpm range, do not forget to set min and max rpms in your spindle pulley.

    Default G0704 problem popped up, hopefully someone has seen this before

    Ok, I did Hoss's cnc conversion 2 years ago. I have had no problem with it except wearing out gibbs. So I opted to do the linear rail conversion using my old column but to keep using my machine I purchased a new column and installed it so I could use my machine while I work thru the linear rail installation on the old column that has the worn out ways.

    Well I took the whole machine apart and cleaned it, installed new gibbs with the re-installation of the saddle and the table.

    In going thru the setup for movenment and backlash, as I have done every time I go thru gibb replacement, I noticed that my table was .002 Higher on one end.

    I took it apart and checked to make sure under the saddle was clean and not causing the table to be at a very slight slant, but all was good.
    I checked the ways on the table, all is good.

    Now I know the column is within .0005" at the full travel of 14 inches true 90 degrees to the base.
    the saddle is true to the base within .0005 at full travel of 9.7 inches. (yes I have both of Hoss's extension mods installed)

    So with both so accurate how is it my table from one end the test indicator does not move more than .0005 over 8 inches, then climb .002 linearly over the next 8 inches?

    I even tried reinstalling the tooling plate and faced it, the mirror finish on the aluminum tooling plate shows the head is correctly trammed, yet when I attached a test indicator to the head
    and then run the table full length and still shows the first 8 inches is withing .0005 and then it starts a steady climb of .0005 every 1.33 inches of travel until it max out at the end of .002 rise in height.

    Please throw all suggestions at me so I can try and fix this.

    It is fixed now, I took it apart again, I worked the table back and forth and found binding in the last 8 inches of travel. It was not found during reassembly of the mill. That is because the gibbs were not fully seated. The final adjustments made to stop any play in the table, saddle or column had not been made yet. When they were made everything was moved with the steppers and the gibbs were adjusted to take all slop out.

    Well it ended up being the gibbs I received from Grizzly. I put the new gibbs in with the steppers disconnected and slid the table end to end and after a adjustment I could only move the table half way before I could feel the binding starting and getting worse towards the end of the table. It would get so tight I would need a rubber mallet to move the table back past the half way point so it would be loose enough to move by hand.

    The Y and Z gibbs are OK, but the X gibb is slightly greater in taper from thin to thick and in height.

    I put the old X gibb back in and everything is fine, back to normal.

    Excellent news ... gave a brother a bit of a fright :-) Glad all is well - Merry Christmas / Happy Holidays my good man.

    Thanks for the update ...

    while we're here :-) got any links on any of your sites or others indicating how I can finish wiring this C11G BoB to a Solid State relay to control coolant 110v power plug? Ive seeming looked everywhere and was headed over to Hossmachine for some possible links and discovered it was - down ...

    Do you have the load connected to the relay?
    Many SSR’s wont light up unless the load is connected. They use parasitic voltage from the wiring.
