Re: Using mach 3 Demo mode

 

Rex,
just an FYI the older original serial ports were also 25pin D-SUB connectors on the rear of the PC, the main physical difference was the PP had holes(female) and the serial had pins(male).

The 25 pin port is the parallel port, the one you want. The serial port is a much smaller port/connector.
With a serial port, all the data goes over one pin/wire in serial fashion. With a parallel, each bit has it’s own pin/wire and all the bits in each byte go over together (in parallel). That’s why it requires more pins.

Just to be perfectly clear, (sorry, I'm not a computer guy) I want a computer with the "hot pink" 25 pin port at the back? I thought that was called serial, sorry.

Thanks again for helping get this off the ground.

It may or may not be pink in color, but it will be a 25-pin Female connector on the PC(it will have holes instead of pins)

?

If you find a PC with a Male 25-pin port, that IS a serial connector, and will not work with Mach3.

I think I got confused because of people interchanging the terms via a google search when looking for the proper cable.?

I actually have the original 25 pin cable, now I just need an old computer to plug it into.?

Re: Using mach 3 Demo mode

 

Matt,
you are confusing a serial port with a parallel port.
mach3 will not work on a serial port or a vga port.

Thanks for clearing that up. I knew it was to good to be true.

Will a 25 pin to the smaller 9 pin serial work? I have another laptop with that. I think it's a VGA cable port or something. Will that work?


Otherwise I will have to scrounge for an old desktop or laptop running XP with a printer port.


Thanks again,

Hi Matt,

In no way can I be called an expert in this but have been down your road earlier myself.
After buying and throwing and buying and throwing; I have come to firmly believe that the only problem free solution is the basic ?under the desk“ mini tower or whatever they call it with XP. None of the fancy doo dahs on laptops are wanted and should be removed or disarmed.?
Remove everything else from its Apps list and make sure it does not have an internet (bug) connection. To load a G-Code file, create it on your ?inside“ computer then virus scan the file and load it into the computer which drives the CNC machine with a thumb drive.

I don’t need or want upgrades or antivirus or powersaving. All of that is disarmed and / or removed.

Since I did this I have never missed a beat in either the mill or lathe computers. ?

Conflicting information about laptops is because some work better than others. The ones that don't, have eco settings that will kick in a screw things up.?If you've got a laptop with a printer port it's worth a shot if you disable all power saving. Safer to start with a PC. Even a cheap old one. The spec needed isn't high.
?
A motion controller is needed to run from a USB or even better Ethernet port like a Smooth Stepper.
?
Any old printer cable would do as long as it's pin to pin and there's no crossing over going on.
?
Probably best to start with an old PC.

Hey Art

?

I am not saying it is your PC, but I had a similar problem. (LOL still having problems). I used an old PC I had (about 200 model) with windows XP on and the machine was just not stable. Sometimes I even could not zero the axis. Or in runs it started to ac really weird. I then replaced the PC with a new proper PC and those troubles ended.

?

So my advice would be, try to borrow/use a new pc and see if it solve your problem.

?

Hope it helps

>>at .57 and about 1/3 of the way into the cut dropped to .71 for the duration of the cut.

?

? This is really only likely possible for mechanical reasons..?it may be an axis that is weak and cannot get past some tough spot, or the ballscrew holder may be shifting upwards when the motor tries to drive it down.

? If it were electronics the Z would be further off at the end, the move in the middle of the run suggests strongly its mechanical.... Id check that Z ballscrew mounting carefully..

I have a 4'x8' cnc router running MACH3 and Vcarve Pro as my CAM software. I have had the same machine since 1999 and use it on the average of 3-4 days a week. I have a job cutting 5pcs. 3/4"x 4'x8' sheets of OSB. The first 2 sheets cut just fine I loaded the 3rd sheet and started the cut file and the problem began. I am using a 3/8" endmill and cutting in 3 passes the first 2 passes are at .285 and .57 deep with the 3rd pass @.71. First pass cut @.18 deep second pass cut at .57 deep and the third pass started at .57 and about 1/3 of the way into the cut dropped to .71 for the duration of the cut. This occurred for all the items on the sheet. after running the file I returned to my Z zero location and re zeroed the Z which was off by .005. The problem seems to be repeatable and not just with this one file I have also tried another file with the same results. Some things I have tried with no change in the outcome.?

Reprocessed my cut files ( could not see anything wrong with the first)
Tried 3 new by different endmills
Checked my table for level (Spoilboard had been surfaced and as expected was level.)
Checked all ground wires to be sure none came loose.
Checked Z axis for smooth operation
Checked all axis for any play
Rebooted computer
Shut down and restarted MACH 3-4 times
Generated gcode using CamBam

?

I am at the end of my rope and not quite sure which way to turn. Any and all help will be appreciated.

?

Thanks

mmmm try to reset z after the 2nd sheet I had a problem that the z axis lost steps on the change of direction . It took a while for it to add up ! so I wrote a program with lots of peck drilling and found it . in the end I changed to servo drives and motors

Re: Using mach 3 Demo mode

 

Matt,
I can answer the first 2 questions.

Yes Mach3 will send outputs in demo mode the only limitation of demo mode is the 500 lines of gcode.
Mach3 will run on laptops the main limitation is if you're using the Parallel Port the voltage on some newer ones is only 3volts which wont drive most PP controllers.
as far as the actual hook up to the Emco lathes I have no experience or knowledge of the interface.

Mach3 will NOT work with a USB to parallel converter cable. It needs a real parallel port, or a 3rd party motion controller like a UC100 or Smoothstepper.
If you can find an older PC with a parallel port, Mach3 will run the machine in Demo mode.
