Port 1 pin 5 is the signal that activates the air clutch that the impact is mounted to. During normal operation it is released and up out of the way. When activated it pulls down so the impact, contacts the threaded rod that pulls in or out the nmtb  40 tool. I hope that makes since because I just confused myself trying to explain that. The machine is a shizuoka AN-S if that helps.

 ??? Ok, it turns out that writing code does not work well for me. Does anyone have more help with my tool change button. I am offering a virtual high five to anybody who can give me some details on how to do this. I need a button to make the z travel up to machine 0 at a feed rate of 100 ipm, activate port 1 pin 5,  (Active high).  I need port 1 pin 5 to turn off ( active low) when pushing that button again. If two buttons would make it easier I am fine with that. I just bought a vital systems hicon board so i emailed them for help on this and they wanted $$$450$$$ to write that for me. That is a little to steep for me right now so Any help would be greatly appreciated. Thanks.

If you are up to it, I could use another button. I have a manual mill that has a button that splits the dro reading In half. It saves me from having to grab a calculator.on that mill, I edge find on one side of the part and zero the dro, move to the other side of the part and find that edge. Once I find the second edge, I hit the divide by 2 button and the dro is cut in half. I then simply travel back to zero on the dro and I am centered of the part. It is a  very handy button and I would really like something like it on the mach 4 screen. I am currently  trying to learn lua but is difficult for me to get grasp. Thanks in advance

Hello all. I need to create a "tool change" button in mach 4. Here is what I would like it to do. If I am asking for to much please let me know, but just go easy on me.

1 upon pushing the button I would like the z to travel at a feed rate of say 100 ipm, to machine coordinate  -.020
2 once it reaches machine -.020, I need it to activate an output. In my case, it is a punamatic clutch
3 I would like the output to stay active until I press the button again, if this part is not practical  or possible let me know
4 I have a manual toggle switch that i activate (forward/reverse) to pull the tool in and out of the nmbt 40 taper once the z is up

So in basic terms, I need to push a button, have the z move up to the tool change position, apply a clutch so I can manually toggle a switch to pull the tool in or out.
I would l Iike to try machine -.020, so it gets as close to zero with hitting the limit switch. I would possibly play with that number to get it as close as possible without hitting the limit.
Thank you in advance for any help you can offer.

Thanks for your help Brett. i will look into my improvised shielding method with the copper tape. I forgot to mention That I installed ferrite cores on my 5, 12 and 24 volt power supply wires. ( from the power supply to the boards) that might not be the correct way or even necessary. That did not seem to make any difference. I printed off the first article to read when I get a spare second. I will try to disable everything until i have basic motion then work up from there. If anyone has any more helpful ideas please let me know. This is my first retro and has been a lot of fun until now. Thanks

I am in need of some ideas on a possible cure for a problem i am having with my 3 axis Shizuoka mill conversion. I will try to list the hardware i am using, but if You need more info please let me know. i ordered almost everything from cnc4pc.

Shizuoka AN-S
Mach 3
Warp 9 Ethernet smooth stepper
cnc4pc c-32 break out board REV 5.4
two c-54 quad 25 amp relay boards
Imach P4-5 MPG
Teco tsta servo drivers
Teco servos, two 1000 watt 2000 rpm and one 750 watt 3000 rpm
Teco westinghouse 7300N3   205-N1 VFD

1. When i connect the 24 volt out pin on the VFD to the common pins of the forward and reverse relays of the C-32 board, both forward and reverse led's both glow dimly.
2. If i run the spindle speed up to 5000 rpm and then issue a M5 command, the saftey charge pump, estop, and VFD alarm led's glow dimly. As the spindle is coasting to a stop, just as the spindle almost stops, those led's get brighter, flicker a bit and i get a EXTERNAL E-STOP REQUESTED. when it does this my contacter that enables my servo drives shuts off for a second then comes back on. The saftey charge pump is not enabled in mach or on the c-32 bob with the jumpers. I spoke with brian from teco westinghouse tech support and he suggested a regeneration resister of 50 Ohms and 300 watts for the VFD. I have tried running the debounce settings in mach and in the ESS up to unreasonable numbers to see if it was noise. I Installed a power filter/ conditioner thinking the vfd was giving my electronics "dirty power". I have wrapped all wires with copper tape and grounded them to the enclosure box. The vfd is mounted in a seperate box behind the main enclosure. I have also tried to make sure all high voltage wires (particular attention the the VFD) and low voltage wires are separated. I tried to jumper the 24 volt pin to the S1Forward of the VFD, bypassing the bob and the led's still glow dimly. When i do this, the only wires that are connected to the vfd  are the analog 10v and ground for the speed control. I am sorry if i am rambling and giving you useless information, i just dont know what info you need to diagnose something like this. I am finding out that i am not as good with electronics as i once thought. My first thought was improper grounding, but now i am not sure. You might ask why not just ask arturo from cnc4pc. He does not answer phone calls or emails, SORRY arturo, but you know its true. Any help would very appreciated, even just pointing me in a direction. Please let me know what info you need. Thank you in advance.
Austin.

After emailing vista cnc about my problem, they replied with this.

"Sorry for the issue you have with the pendant.
Before I send you a replacement, I'd like to try two things to see if the issue can be solved.
1. Try to find a USB hub (any type of USB hub), connect the pendant to the hub, then connect the hub to the PC.
2. Upgrade the pendant with files and instruction from the link below. Use the latest plugin included in the file.
http://vistacnc.com/manual_download/user_files/P4-S  Pendant FW update procedure.zip
Let me know if you still have the issue after this.
Thanks,
Lee Newman
VistaCNC LLC"

After doing the download they suggested, the pendant works perfect again. Lee from their tech support was very helpful  with his quick reply. I hope this might help anyone with the same problem.

Thanks for you help . I  installed the ESS_v10p1d1e plugin. I changed the setting in the lower left corner of the config menu to 2000. I was all ready set to 1 Khz. I ran the same program that was giving me the "out of data" message by line 37 without any problems. the message seamed more prevalent with G code with lots of circular interpolation, so I air cut a pile of holes of varying sizes and depths at 120 ipm. Some of them where 6" deep with a .020" Z step, and some were 17" at 10 ipm and everything in between. So far so good. I'm not sure what made the difference, the plugin, or changing the value to 2000. I will reverse engineer it and let you know what I find. Thanks again

I am trying to cut a semi oval pocket in the mill wizard.

Length            6.75''
Width             2.75''
Corner radius   1.374''
.375 4 flute Hss tin coated endmill

I get a invalid entry" Width must be larger than tool diameter + 2 x Corner radius". Please help me understand why a 3/8'' endmill cannot cut a 1.374'' radius arc. Is there a way to disable this warning. It would be great if it just warned you instead of not allowing you to make the cut. The warning could go something like "Hey, you are attempting a tool path That may leave a undesirable finish. Would you like to proceed? Yes/No." Can someone please help me understand this feature. Dont get me wrong, the mill wizard is pretty handy for some quick and dirty parts but there is a couple of features that drive me crazy. Thanks in advance for your help.
