Spot on Dave :) so i wired up port two pin 16 to another relay to switch on the reverse relay but also had to have a signal wire from breakout board to the spindle go relay the issue i then had was that the sgr was always on, solved this by putting a diode in series from the signal wire that fed bet...

Hi Another silly question The set up of the mach 3 was how I acquired it. In the set up of the spindle m3 is CW and M4 is CCW The spindle is in ports and pins is step pin 1 and step port as 1 Spindle set up is enabled with M3 as Output 1 and M4 as Output 2 here lays the issue I think This is what I ...

problem solved, was a break in the wire from the switch wire to the output of the cabinet

HI I have a starmill PC with a atc. The carousel is all working fine .The question I have when trying to bring the carousel it is very slow and intermittent does not come in all, and some time stops and starts, when its going it it fly's out with force, I suspect this may be due to the pressure bein...

HI All the starmill pc I have has been converted to mach 3. I have the ATC working but their is a switch in the carousel when open it is measuring 5v when close 0v. Question is I have traced the cables back to the interface 65 and 73 but not as the pc electrical diagrams . they go to 42 and 44, so k...

damn lol still good to know not a big deal what is interesting the diagram does show 5v for the speed sensor so not sure where they get this from

So quick update and some more pics. So all up and working , couple of things I should have changed , I should have got a 12,24v relay rather than 5v as the 5v in the cabinet is not wired up if it is I cant trace it as no voltage when tested . Not a big deal as the BOB has a USB input so I can run a ...

Hi Dave yeah sorry I meant 69 is 5v by looking at the original star mill drawings.its a real inexpensive one from Amazon https://www.amazon.co.uk/gp/aw/d/B07912 ... asin_title

So decided rather than mess with the existing wiring I bought a break out board and an additional PCI parallel port card , excuse the wiring mess it just testing before I hook up to the main unit. So I now have the touch probe working, in mach 3 AND also able to control the mist via the coolant opti...

Cool Ill go have a search, ps where are you based . Im in the UK Hampshire

HI Dave Got you :) Apparently the ATC does work, mind you i have not seen it working yet, I am going to get the machine up and working soon as the table turns up and will test it :), I have seen the machine with the 4th axis motor working and the spindle working. Yeah I have seen those videos on you...

HI Dave are you talking about the this picture that shows the circuit board with the two relays that show the HPS4FH-S The chap that converted added the 4 axis which this drives. I presume the relay I had the arrow on is ok to connect to .. Excuse the silly questions a lot to learn :) Thanks for bei...

cool thanks David just out of interest how did you identify it was ac , nothing I can see on the relay indicates it

Thanks yep I'll check those, just waiting for my multimeter to turn up to check power and as David mentioned about relay switching

Thanks David as soon as I get the machine up on a table and connected ill check those ill probably have a lot more questions soon after

HI David

Added more pictures. from the parallel port pins I can see 2 free pins available took a close up of the pins and annotated, Also based on what you said could i just then connect to SGR terminal also annotated on a picture

Thanks

I have just purchased a starmill pc. I wondered if someone could point me in the right direction the machine has been converted to run on mach3 and the chap I purchased it from has added a 4 axis . two questions what is the custom card for in the pics. I am also looking to add a fog buster to the ma...

Hi I am looking at doing this also, I see by the drawings it has an option for a mist relay, I don't pick my starmill up until Friday so will have a look at the electronics then Im looking at adding the fogbuster
