General Mach Discussion / Please help
« on: December 19, 2020, 10:03:32 PM »
Hi all,

Had Mach 3 for years - with no issues. Lately my old XP pc has gone to a better life. I know now that Mach3 cannot run on win10 and any 64 bit system.

My CNC controller is a home built HobbyCnc one, working on the Parallel port.

Since I have not operated my machine for some time now - I really have no idea what are my options here:

Should I get another Win XP PC ?

Is there any workaround that will allow me to run Mach 3 on a win10 PC ?

Is there any gadget out there which will allow me to switch from LPT to USB and work on win 10 or Win7 with 64 bit?

Many thanks in advance.

Hi Tweakie

I did not get to the tool problems yet :-)

I tried today again, and it seems that that my gantry that is moved by one anti-backlash nut is twisting so I get the 0.4-0.5 backlash on mu X axis.

Checked with the D.T.I (you see - I learn fast) the other axes - they were almost perfect - 0.01 to 0.03 backlash.

Took the top part off - and checked the backlash of the X axis by the nut - was almost perfect. Checking the other side of the gantry (one that does not have a nut) - I got this big backlash again.

I guess my best option will be to get another nut and put it on the other and opposite side - this will hopefully eliminate the problem...at least until I start cutting :-)

So I am relieved this is not a problem with the screws and the nuts - hope this will solve the problem.

Thank you for your time and assistance

Thanks Tweakie

Problem is I have only the screw and the nut - and have no idea how can I "adjust" anything.

My screw goes from the stepper via an aluminium connector straight to the unti-backlash nut which is a simple flange housing spring and the collar. The flange is screwed to the bottom of the gantry, and the other end of the screw is rotating freely in a hole that is pretty tight (no interference though)

My tool movement is minimal thanks to the Kress machine collet. I will look for a mechanical movement just to make sure. Other than that I am out of ideas, and how anything can be "adjusted"

Many thanks

Thanks fellas

I am REALLY new at this - so some of the terms are un-familliar to me:

What is D.T.I and how do I use it to set the machine to zero backlash - is this the config/baclash page on MAch3 ?

What are "thrust bearings" and how do I adjust the pre-load on them ?

Thanks guys

I think this is a backslash issue :-(

Did some tests with a dial indicator - have observed funny thing.... suppose I jog the x axis to the left - zero mach x axis and zero the dial - when jogging to the right - the dial initially shows movement to the LEFT and then it starts to move to the right- backlash is about 0.45 mm ???

I have Kerk motion leadscrews with anti backlash nut ??  have no idea how this is happening - when power is OFF - I can see no slack movement between the motor shaft-coupler and leadscrew.

Tried to fiddle with the backlash config - shows better results though

Any ideas how to get rid on minimize the backlash?

Hello Folks

Need your assistance again.

Having problem getting a perfect or even near perfect circle - tried everything I know (which isn't much)

Made a circle on Cut2D - exported manually to Mach3 (the auto system does not work for me..) cutting the piece I get a circle that has in two opposite locations a "tip" that looks like the machine did some straight lines instead of an arc.

Looking at the circle on the tool path in Mach3 - it seems that the top part of the circle (north/south) is bigger then the other half (west east) but I don't know if this has anything to do here.

I set the I J mode tab to Inc, in Mach3 config page, and also checked the exact stop tab.

Tried to do a separate circle from the wizard in Mach3 - looks much better but still can see the pointers.

Checked my axes, can't see any mechanical fault. Did 3 passes from Zero point - the tool went exactly to the same position

To try and show the problem - I drew an exaggerated circle on CorelDraw.

Hope you can give me a hand here.



General Mach Discussion / Jogging buttons on MPG
« on: August 20, 2011, 07:02:30 AM »
Hello Folks

Another question:   I am using the jogging buttons at the bottom of the MPG window. (the one that pops-up using the TAB key) - when going to other screens or back to the first one - it goes away - hence I need to hit the tab key again and again.

Is there any possibility to set up the SW so this window will stay "on" all the time ?

Hi Ian

Thanks for that. Yes you are correct - I did the cut and it was OK - just startled by the curved lines.

Heaps to learn yet :-)



General Mach Discussion / Straight corners are rounded

Hello Folks

Need your help again.

I am using Cut2D SW - and there, all my sharp corners are displayed as expected. However when transferring the file to Mach3 - all my corners are rounded. The part color on the screen is blue, but the corners are in red as if they were changed or marked to show someting I don't understand.

Any ideas ?

Hi Chieffy

I agree with Hood - try to give us more details - when you say "turns the system off" - what do you mean by that ? You should get a message at the bottom that says the reason it stopped (I.E limit switch triggered - or something else) This can give us an idea where to look for.

It may be interference. homing max and mins, units too small or too big etc....
