Mach4 General Discussion / Re: Mach4 Parallel Port Axis Setup

« on: February 11, 2020, 07:38:01 AM »

Hi Tweakie,

Here's the new picture.
I tried out those settings and they don't seem to work. I went back to mach3 to try there, but it also didn't seem to work there when
I switched the y step to an 8 (from 7). 

I have the enable pins exactly the same in mach3 so that's promising, but I wasn't able to find where to use the Enable pins in mach4 which may add to the problem. If you
could let me know where that setting is, that would be great 

Do you think it could be bad wiring or maybe something else that I've configured incorrectly?

Thanks for your help!
Aaron

Hi Tweakie,

I've attached a picture below, hopefully you can see it.
That config that worked in mach3 that I'm trying now is (dir, step) x-(7,1) y-(3,7), z-(4,5).

Thanks again,
Aaron

Tweakie,

I'm using the TB6560 CNC Stepper Motor Driver Board Controller.
The machine was wired up by someone else so I'm not sure exactly how they're connected,
but it looks like there are 4 wires from the BOB to the stepper motors.

I did find an old package with suggested pin layouts, but those didn't seem to work.
Sorry for not being able to give better information.

Thanks Tweakie,

I've just been cycling through different combinations of pins to see what works,
do you have a better way of finding the correct combination?

Hi there,

I'm new to the CNC world and have been trying to setup a machine with mach4. I was able to set it up with mach3 and everything seemed to work fine, so I bought Darwin to try mach4.

The problem I'm having at the moment is that I can't get all axes to run at the same time. I have a direction pin for x as 7, and step pin for y is also 7. For some reason this worked in mach3 but Darwin doesn't seem to like this. Any help is much appreciated.

Thanks,
Aaron
