Hi,

Quote
it has to be 32bit. Is that correct? There was no mention of that in the install requirements.

No. A Windows 32 bit OS is an absolute requirement for a parallel port machine but should make no difference with an external
motion controller like the XHC.

If/when you get tired of thrashing around with the XHC then consider a US or European made controller like the SmoothStepper or UC300.

Hi,
that error means that Mach cannot find the plugin (.dll file) for your XHC controller.

Look in the Mach3/Plugins folder to see if a likely looking file exists. If not you will have to download the right
plugin from the manufacturer of your controller and install it.

You should be able to get this info from XHC......but Chinese manufacturers are very poor at after sales support.
Good luck.

Hi,

Windows 7 with current updates

That is the problem.....recent Windows7 updates from Microsoft have caused a problem with Mach3, or more precisely
Mach's parallel port driver.

There are some recent threads about it.

It seems your choice is to un-wind the offending updates OR move to an external motion controller like a SmoothStepper or UC300.

Hi,
the new shortcut will be created in th same folder as the .xml file, ie c:\Mach3. Once the shortcut is created
cut and paste to the desktop.

Hi,
until about three years ago I ran Mach3 on one, then later two parallel ports to control my three axis homemade benchtop
bed mill. I used a dual core Atom base MiniITX board as PC. It worked really well.

Three years ago I stepped up to Mach4 and an Ethernet SmoothStepper using the same wee Atom PC. The PC being so underpowered
is slow to do the first toolpath draw of a largish Gcode file but fine for milling files. It would be to painfully slow to draw 50Mb 3D engraving
files.

There are a number of controllers that work with Mach4, and only one Chinese one and its absolute rubbish.

At the current time the external controllers, which are Mach4 'native', have a mix of supported features. Currently Vital Systems HiCon board is
the only manufacturer to have developed THC support in a Mach4 ready board.

Warp9 TD's Ethernet SmoothStepper Mach4 plugin does not do THC but has recently added backlash compensation and single point lathe threading.

You will have to do some research on what features are supported in Mach3. If you were considering an external controller go for an Ethernet
connected unit like the UC300, the Ethernet SmoothStepper or a 57CNC by PoKeys. The noise resilience is so much better than USB.
Further I think all of these boards have full realtime function support, ie THC, probing, lathe threading etc. If you want one of these buy direct from
the manufacturer or their nominated distributor, if you buy off EBay or Amazon you'll get ripped with some Chinese copy.....don't do it!!!

If you buy Chines s*********t then don't expect it to work. I've gotten so jaded with people buying Chinese rubbish and then turning up on the
forum to get help to get them to work......and China might as well be on another planet when it comes to getting help, that I don't
bother responding anymore.

Hi,
yes Mach3s parallel port is a realtime, or at least quasi realtime controller and supports both probing and THC
and so should do the job. The parallel port has quirks of it own of course...which I assume you are  familiar.

There are a number of external motion controllers (USB and Ethernet) which do a good job....mostly European and US made.
They are fully functional and the manufacturers support them. The Chinese manufacturers are overall very VERY poor with their after
sales support and even worse about fixing bugs. Chinese controllers are very patchy when it comes to probing, THC, lathe threading
and backlash compensation...in fact all the realtime operations are patchy.

Hi,

However, the controller has only so much control. No Pun intended. If Mach receives the probe signal then Mach should stop and set to zero etc etc.

That interpretation is incorrect. Probing is a realtime operation, that is to say that the probe contact event has to be recognized and operated
on (cessation of all axes movement) within 10us or so. If you waited for the signal to be propagated back to Mach it would take 10ms or so
and another 10ms before the axes would stop....way way WAY to slow.

As a consequence probing is enacted by the motion controller, in your case the NVEM.  Note that Machs parallel port is a motion controller that tries
to emulate genuine realtime performance.

Mach is not and cannot be a realtime computing system.....Windows all but precludes it. For this reason Machs parallel port driver which attempts
to be realtime is such an amazing piece of code, I don't know any other that can produce near realtime performance with a Windows OS.

The bottom line is 'probing is a realtime operation.....if probing is going cranky look in the first instance to the realtime controller'

Craig

Hi,
Mach3 does have its bugs.....however if had a fault with G31 there would be complaints left, right and center....but there is not.
I suspect that the inconsistancies you  have note are those of the controller rather than Mach.

Hi,
the Ethernet SmoothStepper by Warp9 TD.

Changing over is a learning curve but it does avoid the frustrations of the parallel port.

Hi,
from memory you right click the driver. You may be able to delete it directly or you may have to inspect the Properties
to delete it.

You should not have to download it, the code is included in the Mach3 folder.

If you run DriverTest.exe it will install it for you.
