Does not the Gcode FR  display in the window to the right?  Set manually if needed.

General Mach Discussion / Re: CNC Mill Travels too far on Y Axis

And to add to what Craig said, this is a new install correct?  If that axis is  binding in some way or the steppers are not geared right it will miss steps.  I added CNC to my RF31  mill - drill years ago and it was very disappointing, so slow.

New to this forum so bear with me please. Using the trial version of Mach 3 I am unable to activate my Nema 23 stepper motor. My setup may be the problem.

I want to run Mach 3 from my laptop via USB. My set up is as follows:

1. USB from laptop to interface board ( Mach3 Interface Board CNC 5 axis with Optocoupler Adapter Stepper Motor.)
2. Interface board to TB6560 controller/ driver board via DB25.
3. Power from 24V, 15A power supply to TB6560 board.
4. Nema 23 stepper connected to my “X” axis connector.

All led’s are on. I think that means everything is working?
Loaded sample G-Code into Mach3 and hit “ Cycle Start” and nothing happens.
I have setup Mach 3 per tutorial.
Suggestions welcome.

Thanks in advance
Jack


So I am trying to follow what your saying.  The USB connection to your laptop replaces the parallel port. But this USB controller still has to be installed so Mach3 sees it and uses instead of the PP. Your instructions with this USB controller should cover all this setup.  Now unless this USB controller has stepper drivers on the board you need some way to send  the step signals to your motor. Usually just 4 wires, but it could be just 3 per axis.
If this USB controller does not have drivers to run the steppers, now you need those. Usually mounted one per axis, but this other board you have connected may have 3 or 4 motor drivers. We do not know because of lack of info. But from your USB Controller for each axis you only need signal wires maybe 3 usually 4, but you have a 25 pin  Serial plug DB25?

Pictures and diagrams would help a lot.

I use freq drives in my line of work. When you power one down you must wait for the drive to properly shut down for a few seconds, or risk the chance of it going into fault.
Once it faults you will then have to reset the drive before it can start up again. You dont just unplug your computer, to turn it off. It shuts down a bit in the same way.
It also stores power for a few seconds til it dissipates. 
  Ditto, used to install a few and never ever break the output to the motor with a relay or switch while they are under load!

So is it not 1 mm the unit of measure 1 / 2015.748   vs  1 mm / 2016 ?    So maybe I am thinking wrong, but its .0004909 or .00049603?    I usually use a reamer if I want to install a dowel pin.

116
That results in 2015.748031496063........ steps/unit .

   Are you building parts for SpaceX or the shuttle?   Round it up to 2016 and cut some parts?

General Mach Discussion / Re: Z axis problem
« on: January 13, 2018, 10:13:28 AM »
Hi there, I am working with Bobcad cam V28 and mach 3 using a usb motion control card. I got everyting working fine but my Z axis does not pick up from one cut to another. I can jog the z axis up and down so, the motors are working. Using the wizards on Mach 3 it shows the z going up and down. any suggestions ? thanx Luan.

What post processor are you using and which USB motion control board?

Is anyone using Mach3/4 for serious machine control?


 I am seeing large 4x8 foot router tables with prices exceeding $20,000

A $20K 4x8 router is a fairly low end machine, from my perspective. But I use a $150K router every day.
WinCNC is a popular control  in the $20K-$50K price range of machines, and costs about $1500-$3000, depending on options.

I've seen older big routers like a Biesse converted to use Mach3.
Would I use Mach3 on a new machine today? No, there are better options available.  But I still use it on my current machine.
Mach3 was written over 10 years ago, and development stopped over 5 years ago.

Mach4 is probably much, much better than Mach3, but hasn't won a lot of people over, for a variety of reasons.

  The 20k is a one year old used Camaster. That poster is looking at spending $60k USD on a new one.  He is a small business with only one other employee.

I have a question about i/o port for mach3. My parallel port is lpt1. should that be the port for the config port and pin
Yes, but if you need to ask that question you have a very long steep learning curve ahead.

I am using Mach3 for serious CNC machine control and it is more than earning it's keep.
I am using Mach4 as a 'one day' replacement for Mach3.
Price / cost of the machine has little to do with it.

Tweakie.
 OK but surprise I am on another forum (not CNCZone,)  and the used prices are starting at $20,000 USD  (4x8 foot table)  and new $50k on up. The one thing that comes out in the discussion, "they are using real control systems, not Mach3"!  Been involved in hobby CNC for years and know spending Lots of money upfront does Not guarantee that You will make lots of money! Its how you run your business and your market.  Thanks for the reply.
