General Mach Discussion / Re: M3 and M4 compiler issues...again
« on: November 10, 2014, 07:39:38 PM »
Hi Grahm
Thanks for taking the time to write that up.
Here is what I did for half a day Saturday and all day today. I started up Mach then shut it down. Then I started it again and ran my job. So far using this method I have not had a single problem. I have about 4 or 5 days on this job which has 3600 tapping calls. I'm going to keep doing this until I either get through the job or it screws up again.

On thing I changed when I rebuilt my computer was I auto started Mach. I'm wondering if that is causing the problem. Something along the lines of if you start mach before windows fully loads then it causes problems.

What sucks is I could go 6 months with it working like this and then have it start up again.

It's really weird how some times it likes the macro and sometimes not so much. All in the same run. I'm going to execute G84 40 times in a row but 41 through 48 you're SOL.

Thanks

Those were all happening during a G84 tapping cycle so I'm not sure how that calls up the spindle.

General Mach Discussion / M3 and M4 compiler issues...again
« on: November 07, 2014, 05:25:16 PM »
Hi
Having some issues with M3 and M4. Mach is blowing right past them. This is happening on two different machines with the same mach version. .056 The other machine is kind of basic with no ATC and I haven't done any spindle direction changes. I will miss a M3 occasionally.

The real problem is my main machine with the ATC.

The error I get is "Scripter compile error in M4.M1s."


Here is some pertinent error stuff:

The first error was in the middle of a tapping cycle. Fortunately when the spindle didn't reverse the tap pulled out of the collet. I wasn't watching the machine so I didn't realize it happened. The second set tap 12/24 I happened to be standing there when the spindle didn't reverse. It seems to be a random thing. The second set of 5/16 has 8 cycles. it only errored on 6. On the 12/24 it completed 3 before it kacked.

I've been having this issue for a while with various versions. I had a hard drive take a dump and I had to start from scratch and afterward it seems to be happening more frequently. Counting the tap and the scrapped part it's in the $30.00 range every time it happens so it's starting to get costly. This time it was twice in one run two different parts.

I really wish mach would estop on compiler errors.

Thanks

General Mach Discussion / Re: Mach3 / UC100 Connection lost?
« on: October 30, 2014, 06:30:10 AM »
Keep in mind if you have that kind of noise it's not the fault of the UC-100. So moving it is just a kludge. That kind of noise will affect the rest of the electronics in small ways. You should be able to plug the UC-100 into the BOB and run a decent USB cable to the computer without issues. I have 2 setups like that and no issues. I would use the UC-100 at this point as a "canary in a coal mine" and get the noise under control.

Just my 2 cents.

I have 2 UC-100s and 2 UC-300s. They are all on standard motherboards and I've never had that problem. My guess is the laptop is probably turning off power to the usb to save energy. There are settings in the device manager to keep the power on at all times to the USB bus

Thanks hood I'll check into it.

General Mach Discussion / Re: AC servo for spindle

Hi Hood
right now I'm overdriving the 1725 motor at 120hz with a 1.75:1 ratio so I get around 6000 rpm. Down low is where I need the most torque for drilling and tapping and that combo seems to work well. I never change the pulley.

I'm using the UC-300 motion controller and it doesn't offer rigid tapping so I figured on doing some sort of swap axis kludge. I would also do a swap axis for the indexing as well.

Thanks

General Mach Discussion / AC servo for spindle
« on: October 25, 2014, 11:01:32 AM »
Hi
I'm thinking that switching over to an AC servo for my spindle.
This is on my knee mill. The things I'm trying to accomplish are:
Spindle indexing for ATC
Rigid (tap to an accurate depth) tapping
Torque over a wider range than I currently get from my VFD.

If I do a straight conversion from the 2hp motor to KW it's 1.5KW. But since AC servos have more torque at a lower range do I really need 1.5KW.

Most of the AC servo drives and motors I see are in the 2000-3000 rpm range. I run spindle speeds up to 6000 RPM so there will be a loss of HP there.

I know a few of you run AC servos for spindles and I'm looking for real world feedback.

Thanks

General Mach Discussion / Re: Keyboard Stops Working
« on: September 21, 2014, 01:54:09 PM »
I have the same issue with jogging and I really think it's keyboard or keyboard driver related. It will jog fine then stop. I had an old ps2 keyboard trackball combo that was starting to get flakey. It craped out in the middle of a job so I grabbed one of the USB keyboards from another machine. I plugged it in and it works except it has the jog problem. It's an irritant more than a problem so I haven't tracked it down.
It's an adesso keyboaard so it's not junk.
