Mach4 General Discussion / Mach4 Canned Cycles

« on: December 13, 2021, 03:06:25 PM »

When I select the "Canned Cycles" in the wizards list nothing happens.

My Mach4 Hobby is licensed.

Am I missing something?

Mach4 General Discussion / Mill: General question about limit switches

« on: December 12, 2021, 02:49:25 PM »

I currently have 2 switches on X, 2 switches on Y and 1 switch on Z.

Is it best to have 2 for X and 2 for Y or single for each with soft limit enabled?

Mach4 General Discussion / Mach4 Lathe: Reducing the chatter

« on: November 08, 2021, 02:27:58 AM »

Hi,

Is there a way or trick to reduce the chatter when turning large diameter pieces on a lathe? Like what they call Spindle Speed Variation in the video.

Mach4 General Discussion / Empty \Macros folder in newly created profile

« on: October 14, 2021, 03:28:05 PM »

Hi,

I created a new profile and noticed the machine doesn't respond to M6 command because the Macros folder was empty. So my question is if I copy and paste the macro files from the original Mach4Mill\Macros folder into my newly created profiles Macros folder, will them work?

Mach4 General Discussion / Cant get MPG smooth incremental jogging

« on: September 26, 2021, 05:14:18 PM »

Hi,

I've made an Arduino MPG with pulse generator which is connected to Mach4 via serial. Everything works. Sends and receives data. However I can't get Mach4 to jog smooth and continuous jogging. When I turn the wheel the axis moves the amount of the increment and stops then again. What I want is, when I turn the wheel slow I want the selected axis move slow but continuously. And wise versa: as when I accelerate spinning the wheel I want the axis act the same and move fast. You know, I just want what we all want

The code is simple. When mach receives "I" or "D" from serial pendant mach gets the selected axis and jog increment then jogs the axis with it.

How can I change the to have a nice and smooth jog? I'm open to all suggestions.

Thanks.

Code: [Select]

    elseif Command == "I" then
--mc.mcCntlSetLastError(inst, "Jog INC")
        JogInc=mc.mcJogGetInc(inst,0)
MPGAxis = mc.mcMpgGetAxis(inst, 0)
if(mc.mcAxisIsStill(inst,MPGAxis)) then
mc.mcJogIncStart(inst, MPGAxis, JogInc)
end

    elseif Command == "D" then
--mc.mcCntlSetLastError(inst, "Jog DEC")
        JogInc=mc.mcJogGetInc(inst,0)
MPGAxis = mc.mcMpgGetAxis(inst, 0)
if(mc.mcAxisIsStill(inst,MPGAxis)) then
mc.mcJogIncStart(inst, MPGAxis, -1 * JogInc)
end
    end

Mach4 General Discussion / Ease-in and ease-out spindle on M3 and M5?

« on: September 12, 2021, 04:47:22 PM »

Hi,

My spindle motor is an AC servo and it is driven with 0-10v analog. Currently the servo does hard start on M3 and hard stop on M5. Is there a way to setup Mach4 to increase the analog signal from 0 to the desired speed like 500ms so it'll kinda soft start and vice versa?

Thanks

PoKeys / Pokeys 57e and Mach4 mill spindle encoder SRO question

« on: July 13, 2021, 09:36:01 AM »

Hi,

I wired up the servo encoder to my M16D (using Pokeys 57e). I did all the steps but I am not able to get Mach4 main screen to display the actual spindle speed. Please see the attached images.

I see the input pin for index is triggered when the spindle is spinning in Mach4 log. I also confirm the values are changing on PoKeys "Encoder Raw Values" screen.

So it seems like that I should see the spindle RPM in Mach4 but the Spindle SRO value is always static.

What am I missing?

Thanks

Mach4 General Discussion / Turn | Is eccentric turning possible with Mach4?

« on: October 06, 2019, 03:02:28 PM »

Hi,

I have a 2 axis lathe with encoder on the spindle. I use SolidWorks/SolidCAM to generate g-codes. No problems at all. Only thing that I wasn't been able to get SolidCAM to post a simple eccentric turning program. So I guess SC doesn't support eccentric turning at all.

Question is how can I write a program to cut a piece like in the attached image?

Thanks,
Suat

G-Code, CAD, and CAM discussions / Best Cam for 2 axis lathe?

« on: August 06, 2019, 03:56:35 AM »

I use Mach4. I was doing fine with Mach4' canned cycles until yesterday. Yesterday I needed to cut a complex shape but I wasn't able to do it with Mach4 canned cycles.

I normally use SolidWorks with SolidCam but I could not find a proper post processor for Mach4. So, I need switch to another Cam software for lathe.

What Cam software should I use for lathe with SolidWorks + Mach4?

Thanks in advance,
Suat
