General Mach Discussion / Re: Can't move Z Axis in positive direction

This problem can be caused by either the direction connection to the driver missing or possibly the direction signal pulse edge timing relative to the step pulse being wrong.

Can you jog the axes?  If so then Mach3 is probably working OK and you shouldn't need to re-install.

The G-code interpreter expects to see and recognise a limited range of characters, except in any comments section of a line (a "block" in g-code speak.  If you have any other character you would probably get an error like the one you see.  It could even be a non-printing character.  That's why I suggest you post the code so we can see if there is a problem.

If there isn't a spurious character then re-install.

Can't possibly say unless we can see the code.

.....even better if chatgpt could be used to write the code.  Does anyone know what I should tell chatgpt so it does this for me? 

Well I guess in principle you would have to fully define the function of the code you want chatGPT to write.  For example you could write it in C - but then you'd have solved your problem.

I can imagine that Mach could control a robot with only rectilinear motion, X, Y, Z and a couple of rotational axes.  That could suit for example a pick and place application.  But for a robot arm all the motions are rotational, even if you want to move the control point in a straight line, so there would need to be a translation stage in between the Mach trajectory planner and the motion controller to resolve the straight line in say the X direction to appropriate rotational moves.  AFAIK Mach does not incorporate that of have the hooks to do it.

But if you are not convinced why don't you contact NFS sales support and ask them?  They are a commercial organisation so should be able to help potential customers understand the product capabilities.

Well despite the great press it's getting at the moment I don't think chatGPT is all that reliable when it comes to given good factual answers, based on some recent personal experience.  I think there is also a misunderstanding both perhaps on the part of chatGPT and your manufacturer as to what g2core does compared with Mach3/4.  Mach is not just, or even, a motion controller as I understand it.  Mach3 can control motion using stepper type motors with what amounts to a parallel port plugin which is the "motion controller" part.  Though I understand there is a PP plugin for Mach4 it is deprecated and an external motion controller is preferred - which might logically be g2core or GRBL but neither of those are supported.  There is a range of motion controllers for Mach that connect using either Ethernet or USB - their suppliers need to implement the API to Mach which is not open.  Though Mach can certainly control 4 axes, and might do 5, it is optimised to run CNC machining define by G-code commands rather than a robot.

If the computers are networked you might use a virtual terminal program on the one you use for design to provide a remote desktop for the other running Mach3.  RealVNC I think is freeware.  I have no idea if this would be compatible with running Mach 3 as well.
