 I have my STEPS PER at 4000, my microstep at 1/4. The native STEPS (no microstepping) is 1000 = 1 inch. I have the velocity set to 120 and the accel to 24 (20%).....

I'm 100% that it is I that is doing something wrong but I'm not seeing it.

Hmm, now I'm wondering about my Jog. I'm wondering if the speed I see when jogging in MOTOR TUNE is actually a lower velocity than selected (lower than 120, which of course would be wrong) and that the velocity I see when RAPIDS occur in the cut program is actually the correct speed for what I have selected (120)......

Now that I'm calculating what 120 would be in terms of velocity, it would be 2 inches/second. Pretty damn fast......So, now I have something to look at and that would be the jog speed I see in tuning.....

Just went to have a look at my jog speed....Sure enough, it was set to 25% and the velocity I was seeing when tuning was 1/4 the velocity set....What a dope! That explains it all. Like most people I was tuning by eye/ear and selecting a "comfortable velocity" by eye instead of actually working the numbers like I just did above.
I'll have to lower the velocity to around 60 and the accel to 12 and of course change my jog speed to 100%!!....That should do it!

Thanks for the help,

Yes, I am overriding the Rapid rate via the "BAR" on the Program Run screen (inside the FEEDRATE box) where I can click on the green bar for the RAPID and change it by percentage. That seems to control its velocity independent of the FEED rate I have selected. This only works if I decouple the two (FEEDRATE and RAPID) under the GENERAL Tab.

The cutfile has the FEEDRATE set to 12 (I set this parameter in CUT3D) and if I don't uncheck the aforementioned box under the GENERAL TAB, the RAPID status bar always shows 100%....However, 100% of what parameter though is what I question. My first thought was the same as you guys say, 100% of the maximum velocity I set in motor tuning but like I said, my eyeballs tell me the RAPID seems to be far faster than the maximum I have set in Motor tuning.....

Thanks Craig and ZASto. I'll have to think on this.

Although I haven't actually measured the velocity of the 'rapids' (G0's in a CUT3D cutfile I'm using. G1 is fixed at 12 tpi) they appear blazingly fast as compared to the maximum motor speed I have programmed in motor tuning. They have been a problem causing missed steps. As a workaround I've decoupled the Rapid and the Feedrate in the General Menu by unchecking the box. In that way I can moderate the Rapids independently of the Feedrate.

edit: I should clarify that in troubleshooting my missed step problem I have the Z and Y axis turned off. The only axis I've been observing is the X axis while running the cutfile, periodically pausing the program to check for missed steps (I marked the shaft and motor body with tape). Oh, and no there's no slipping of the couplers, etc. There is an area in the cutfile where there's some RAPIDS that cause the X axis to move, as I said before, blazingly fast.....

General Mach Discussion / MACH3 RAPID's: What determines the velocity?
« on: August 30, 2018, 04:29:30 PM »
So, having tuned my motors in Mach3 on my mill, whilst running a cut program, I noticed that my 'rapids' accelerate and move at a much higher velocity than the velocity I set in motor tuning.

Question: What dictates the speed of rapids? Is it some multiple of the velocity set for the axis? If so, what is that factor?

Yes, that was the problem....On the two PC's that worked, the file self-extracted from the zip folder. The XP-Broken does not self extract for some reason. I did however unzip it manually and then opened the folder it was enclosed in (mach3) and placed the .dat file directly into Mach3 root. It works now......

Thanks all...

RonC- I have tried it both ways, but when I've tried the unzipped way, it produces a folder, and I have placed the folder into the MACH3 root directory. I never tried placing the just the Lic.dat file there. But, alas, this works on other PC's so there's something going on with this XP-Broken......In fact, the file's not unzipped in the current working copy I placed on the XP-Broken pc.

I can switch back to the defective install simply by renaming the entire folder so I'll try it later.....

Well, thanks but given I'm not trying to debug Mach3 but only trying to integrate my Laser I don't want to get diverted on a boondoggle that's simply going to eat my time.....The one thing I counted on was the MACH3 software cooperating..... ;D  It hasn't. It could be the PC, likely it is, but like I said- no time....

So anyway, in the interest of going forward and staying on track with my project, I tried something that did work. I copied the entire folder from XP-working PC and installed it in the C: root of XP- Broken PC (after renaming the old folder).

Given the motors go whirrrrr....and I can jog, I have to assume I'm good to go. It also says 'licensed to John Doe' as it should. I just need to edit this profile (my Router) and make it a profile for my Laser machine.

I'll eventually go back and deal with the Mach3 issue later....ONLY IN MY WORLD, IT SEEMS...TWO DESKTOPS AND THREE DAYS LATER I CAN FINALLY MOVE FORWARD. ::)

Thanks,
Bob T.

I got the license from New Fangled/artsoft. I'll have to check the versions but here's the funny thing- The original version was dowloaded just about a year ago. That's an XP machine, we'll call XP-working.

I had another machine, one running Win7 and a 64bit machine. We'll call that 7-64

I downloaded the same version of Mach3(yesterday) that I just loaded to the (newly purchased/old)XP machine, we'll call XP-Broken, and it did indeed said 'licensed to john doe' on the 7-64 bit machine.....after I dropped the zipped license folder into the Mach3 folder. It does not on XP-Broken.

So they both had the same version downloaded from Artsoft yesterday, but one recognizes the license (7-64) and one does not (XP-Broken). That machine, the 7-64 bit, I'm told, will not load the parallel driver (and in fact it did not install it), and so I purchased this machine today: XP-Broken, 32 bit, in the hopes to get it all installed on a compatible machine......

As an anecdotal observation, I do see that the zip folder, containing the license, has an icon assigned in XP that's a generic; in other words it appears not to be associated with an unzip tool in Windows XP.....it does unzip however if I double click on it. Anyway, it's something I'll look at.

Hi.
First, I have Mach3 running on another machine I use for a CNC router. It works fine. I just bought a 'new/old' pc running XP and it is a 32 bit machine. I have downloaded Mach3 and it successfully loads, including the parallel driver. I have a product license in a zipped file; 6667 I think is what it's labeled. I have dropped the file into the Mach3 folder on my C: drive.

I fully expected Mach3, when opened, to say 'Licenced to....' but it still displays 'demo'. I have been through several iterations of loading and reloading Mach3, booting/restarting, including deleting the entire folder on the C: drive and starting from scratch- same thing...Says 'demo' and also says 'demo' in the HELP screen. I took the license from two different sources: 1) the working PC and 2) the original email I recived when I purchased it........Neither works on the 'New/Old' PC.

Am I doing something wrong here?
