Hi Christoph,
may be a way around this is to disable ALL inputs and outputs on the NCpod config page and then
work with just one input until you've got it sorted. Then choose one output and work on that.

The outputs for the motors are fixed and labeled, you are using those I presume?

Hi,
rereading your posts and there seems to be some confusion...

I have changed the breakout board for a new one. Same exact problems. Re-installed Mach3 - no change. I am using an ESS. I purchased a PCI Printer port and couldn't get any communication. I'm running windows 10 so from what I read that wont ever work. So I went back to the ESS.

If you are using Windows 10 then your wasting your time with a parallel port, it wont work with a 64bit OS.
If you are using an ESS then the pics you've posted are not really meaningful, they are settings for the parallel
port which of course does'nt work!

Your settings, things like motor outputs must be made in the ESS plugin.

When you first fire up Mach you should be asked which of the available motion plugins you want to use. While its
common to see the parallel port listed don't bother with it, it doesn't work! Find the ESS plugin and fire it up.
If the select screen doesn't show go to Function Cfgs/Reset Device Sel... <ok> and fire up Mach again.

Now that you've got the active motion control plugin you can configure it.

I use Mach4 and am not familiar with how to set ESS in Mach3. The Warp9 website has really detailed instructions,
videos and if you're still stuck the forum.

Hi,
I think I would try, even temporarily a 47k resistor, only need be a low power type, between the base of Q1
and the emitter of Q1. If there is indeed a problem that the transistors are not switching Q1 will be the most
sensitive. Its so simple to try...might as well give it a go.

Hi,
if you're going to buy a new card buy from a US or Euorpean manufacturer, they make stuff that works
and will help if you get stuck. Chinese manufacturers might as well be on another planet when it comes to help.

Hi,
no, remove the original MachLic.dat and replace it with your one.

Hi John,
if you wish to try to protect your driver from over voltage excursions as a result of deceleration try something like this...
It goes across your 24V supply, when the MOSFET turns on it loads the supply with the 10ohm resistor to absorb the
energy of the excursion. Obviously the 10ohm resistor has to be grunty, I would recommend 100W

The op amp is just a comparator, when the 24V zener starts to conduct a few mA then it will turn the gate of the MOSFET on.

This is broadly the same idea used in VDFs and servo drives, of course the DC link voltages are likely to be 320V for single phase
or 580V three phase rather than 24V as here.

Hi,
well that makes sense...that board is not a parallel port board its a USB motion controller.

The screen shots you posted in your first post are Machs parallel port settings and you will pretty much have to ignore them until you
work out which still have relevance with your controller active.

When you first fire up Mach you are asked which of the available motion control plugins you want to use, you may have a choice, either a
parallel port, which you don't want or the XHC one which you do. If the screen doesn't show go to Function Cfg/Reset Device Sel.. <ok>
and fire up Mach again. Do you see the screen. Select the XHC plugin and set it up according to the manufacturers specs.

Hi John,
the extra diodes only double up whats already inside the IC. The diodes shown are schottcky and so have a lower forward voltage drop and ultra fast
reverse recovery which may help. As tweakie says they do work and are cheap, even if you do ping one is it the end of the world?

What puts these drivers under real stress and in fact ALL divers is when a motor overruns on deceleration. So you have the motor singing away
at 1000 rpm and you want to stop....and for CNC purposes with as high deceleration as you can, the motor now becomes a generator and power
flows back to the driver IC and into the DC link capacitors of your power supply. If the voltage exceeds the breakdown voltage the switching devices
in the IC go into second breakdown with consequences for reliability.

As I say ALL motor drivers have to accommodate this problem, it just plain physics. You may have seen 'braking resistors' which are sold as an add-on
for VFDs, all they are is a place to dump the extra energy under intense deceleration and try to stop the DC link voltage going thru the roof.

Hi John,
Limits and Homes are input signals.
Limits are X++,X--, Y++ etc, disable all of them to start with. If they are disabled it doesn't matter what pin is assigned, but suggest you put '0'
as the pin. Pin 0 doesn't exist.
Homes are X Home, Y Home etc disable all of them to start with and assign them to pin 0.
Your Estop should be port 1 pin 13, or at least that's the pic you posted. Try Estop active low. Fire up Mach and see if the Estop button works.
If it doesn't try Estop not active low and try Mach again. One of the combinations should work if your machine is wired with the Estop wire
going to pin 13 on your BoB. If not you're going to have to trace the wire from the Estop to the pin on the BOB.

You don't need a licence at the moment, even if you had one it won't change anything.

You might go to the Artsoft site and get:

Mach3 CNC Controller
Software Installation and
Configuration

Manuals seem to work best when read, sometimes more than once.

Hi,
I see in the second last pi you posted an output Dig Trigger? Whats that for? Do you need it?
