Mach4 General Discussion / Re: Mach4 Printer Port Discussions

Thanks Art for all the great work and effort you have put into sorting the software problems and educating us all on how to configure our systems and set up for using Mach4. You need to be getting on with that laser (and the grayscale plugin of course).

I am also very interested in following your CAM development for GM - it can't be far away now that the buttons are operational on the GUI.

Should I determine wiring by using a multimeter ?

Perhaps best just to check one motor - For those connections...  Red & Blue should show continuity and Green & Black should show continuity.

Brains Development / Re: Use brains to directly modify motor step output

Just my opinion...

Because it's a lot more than just modifying a motor's step output - the two motors have to be simultaneously driven in the same or opposite directions etc. "brains" is not going to help you.
The only satisfactory method wit H-Bot control and Mach3 is to modify your CAD/CAM's post processor to write the commands to handle the two motors in place of each conventional X - Y axis move that would normally be written to the Gcode.

Good point DoubleTrouble - is the existing fan operating correctly and efficiently ??

Hi Derrick,

Perhaps you could perform this simple test…

Remove the red wire (connected to LPT Pin 7) from your laser PSU. With the Pot set to < ¼ power level, switch on the system – does the laser fire continuously ??

Measure the voltage between the “L” terminal and the “G” terminal on your PSU (with the system powered up and the red wire still disconnected) is it 5 Volts ??

Well, it looks to me like the existing fan is more than adequate to do the job so I don't think adding another fan would serve any useful purpose. I assume that the board closest to the fan is your Z axis and the two slo-syn's are your X an Y ??

Yes, one driver chip for each axis is usually the case.

Most single phase routers are "double insulated" and only have the two wires. If electrical noise was an issue I think you would see the axis position fault on a much more regular basis, if not continually.

The driver will run warm but the actual stepper motor driver chip must not be allowed to exceed the manufacturer's specification on working temperature.

(On another forum some have experienced similar problems to those you describe and fan cooling resolved the issue - thus my suggestion  ).

Just a shot in the dark but I would be inclined to look at the stepper motor controller and make sure it has enough circulated air cooling. Perhaps fit another PAPST type fan ??

Very useful information CAIO - thanks for posting.
