Hi Alex,

I think 10mm out of position represents too many lost steps if they were just random so my best (and wild) guess is that you have a motor driver overheating and perhaps partially shutting down.

Perhaps check the temp. of the driver chips and temporarily fit a cooling fan to see if this makes any difference.

The arcs version of my test test file (Star Trek.tap) can be downloaded from here; http://www.machsupport.com/forum/index.php/topic,18345.0.html

The file contains a few unnecessary M63P1 commands (my post processor still needs some work) but it should give you an idea of what is required.

is there a setting in Mach to tell it to set S to 0 when the M5 command is initiated?

Hi Art,

In the folder C: / Mach3 / macros / Mach3Mill (or whatever Profile you are using) add the line   Code("S0")   to the file   m5.m1s  then save the file.

it just loses steps and kind of shifts position and the part that ive been machining for however long, be it an hour or 6 hours is ruined, its even more painful when its the finishing pass in the last 1000 lines of code.

Hi Alex,

Could you perhaps post a picture of what is happening to the work when it goes wrong ?

Pin 1 is often not used when it comes to parallel port operation (it is bit of an oddball).

Can you perhaps use a different pin (2 - 9, 14, 16, 17) ?

Might you point me to a sample mill  G code file that will run properly on a freshly installed copy of the Mach3 Demo software;  using the default mill profile ? I understand machine coords, work coords etc.

There are many here to choose from; http://www.machsupport.com/forum/index.php/topic,18345.0.html

Excellent.
I am pleased you found a perfect solution.

Just a note for others - when fitting a PCI Parallel Port card to a new PC make sure the card is to the old 5Volt standard and not the new 3.3Volt standard. If your controller is expecting 5Volt TTL logic and only gets 3.3Volt TTL logic then loosing steps is often the result.

General Mach Discussion / Re: Mach3 on USB card Windows 7 help please

Tweakie,
I would rather use Mach3, I have ran it since I started carving.

Unfortunately, that's not a Mach3 compatible board.

One of the questions would be, which should I go with, Mach3, or Planet CNC on getting my machine back running?

Obviously I am biased but I would recommend Mach3 or 4.

So really want to try making the USB board work if at all possible. I have no paper work at all, so any help with this would be so kind.

Perhaps if you provide full details and a picture of your USB breakout board someone may be able to help.
