Newfangled Solutions Mach3 Wizards / Re: Newfangled wizards for Mach4
« on: November 24, 2012, 09:14:00 PM »
The ability to delete ANY operation ( instead of "delete last operation") in a string of operations is something that I have been asking for. This would be MOST useful when one is developing a complete program for a part which is still in a design stage without the use of a dedicated CAD/CAM software. Also (perhaps this is not the place to ask), does anyone have any problems cutting a female metric thread in an Imperial machine using the thread mill wizard? I have tried two different methods. Using the machine in inch mode (G20) and inputting converted metric size and pitch to equivalent imperial measurements and setting the machine to metric mode (G21) and letting the wizard do the work. Both methods seem to generate a pitch that is not quite right. I have used the thread mill wizard to generate imperial threads with no issues.

I have been using these Wizards for some time and for the most part, they are a great way to create a part without the use of a dedicated CAD/CAM. What I would like to see is the option to delete any operation that you have created using the Wizards. As it stands now the only option that you have is to delete the last operation that you have created. If you are developing a part using the Wizards and you want to refine a certain feature of the part you have to delete the previous operation until you get to the feature that you want and then edit the parameters in the specific Wizard. It would make much more sense and much less work if you could select the Wizard you want to delete instead of scrolling back and deleting each Wizard in your program/part/g-code.

Just for kicks, I downloaded a very early version of Mach (Version R2.63) from the FTP server and guess what... the pulse frequency shows up at 25379 and the time in int. varies from 7.2 to 4.8.

Varies from approx. 10.8 to 8.2.

The problems I have been having are so intermittent that I would have to be half Irish to find them.  ;D
But I have checked all my connections, all my wires are properly grounded and shielded, voltages are what they are supposed to be and I have not made any drastic changes to my system (other than adding my fourth axis). I do have a feeling that my problem may lie in the computer or BOB region as the last hiccup I had was (I believe) outputting too many pulses (perhaps in the form of noise). That is why I asked if the pulse frequency in the diagnostics page was supposed to be displaying the kernel speed (25 kHz). I do remember in one of the Mach tutorials that Art displayed his pulse frequency in his system and it did not waiver meaning his system was very stable. I need to find out how to make my system just as stable.

Just downloaded newest lockdown version of Mach and noticed on the diagnostics screen that the pulse frequency was not very stable. It jumped from 1 to 387 and anywhere in between. I understand that this should be reading what your kernel speed is set at (which is set at 25,000 kHz). Should this be something to be concerned about or something I should not be worried about? The reason for the update to Mach was because my machine was acting very peculiar. The Z axis would plunge into the part on my 4th axis and my 4th axis would rotate when not commanded to. Another time (cutting a spur gear) the y axis would loose position and then cut much too deep on the next cycle. This only a hobby for me and I cannot afford to keep replacing damaged cutters and material if this can all be avoided.

Thanks,

I have purchased a Mach3 license from CNC4PC and have had no problems. I did send CNC4PC an email regarding the lower price of Mach3 and he said that sometimes vendors get a discount.

General Mach Discussion / Re: spindle speed control
« on: November 29, 2007, 01:07:43 PM »
Go figure! I post a question on this forum after weeks of frustration with my Mach3/ Taig mill setup and AFTER I post a question the whole damn thing comes to life!!  This forum truly is a magical place! ;D

Well, I've been away from the computer and my CNC setup for a few days due to frustration. I finally went back to it, turned on the computer and started playing with Mach3. Went to MDI screen and inputted M3S500 and my spindle came to life! I did not do anything differently other than downloaded a newer version of Mach3 ver. 2.6. That must of done the trick.

jimpinder, thank you for responding. Regarding the KBIC board; this is the speed control for my spindle. It is an analog unit with a pot that controls the speed of the spindle (outputs 0 to 90vdc). It can be controlled from an outside source by replacing this pot with a 0-10vdc signal. This is where my BOB comes in. It has a built in converter that takes the 0 to 25kHz(?) signal from Mach3 and transforms it to 0 to 10vdc. This board does not control direction of rotation. One would have to do this externally through relays etc... The inhibit circuitry on the KBIC could be used for dynamic braking and/or motor reversal. But I'm not there yet. The relays ( there is actually 3; 2 mechanical and one electronic) function on the BOB, is to apply power to the KBIC board. I then input a speed through Mach and the spindle rotates. I guess I could control the spindle through Mach3's S command, but I get a better warm fuzzy feeling doing it this way. :)

Alrighty then. Now that I've got that out of the way, I have a few more questions about spindle control.

In the spindle calibration and testing screen, there is a section that says pulses/rev zero for index pulse. This is set to one on the screen and should be zero as I am using an index pulse and there is no way to change it. Is this a bug or does it make any difference? Also, the RPM display; is this strictly a display or does it provide a feedback for Mach3 to control/maintain the speed of the spindle under various loads? And one more question. What does the spindle calibration actually do? I could not find any documentation on this feature.

Thanks in advance.

General Mach Discussion / spindle speed control

Hello. First post here, so be gentle. I have been using Mach3 on my Taig mill for quite some time. Everthing seems to work OK except the speed control. I have a DC motor being controlled by a KBIC control board. I also have a CNC4PC BOB feeding a Xylotex driver. I can turn the relay on the BOB for spindle on/off via Mach3 but I can not make the spindle turn. I believe I have everything set up in Mach to do this but Mach does not seem to output a signal to the BOB. I have pin 14 set for the spindle step. In MDI in Mach3 I enter M3S100 and I hear the relay on the BOB activate but the spindle does not rotate and pin 14 does not turn on (LED on BOB). I have followed the instructions on the manual for the CNC4PC BOB to the letter. I have gone through ports and pins, spindle setup, output pins everything I can think of, to no avail. I have even tried downloading a new version of Mach3 with no success. I am at my wits end and I need your help please.
