501 dsp pendant large files problem

[stirling]

OK - so I've just been looking at the many and various brandings of this Chinese controller. Each and every one of the associated manuals say you can run files direct from USB. In fact in order to run from INTERNAL memory the manuals say you must first explicitly copy them to the internal flash.

So you go to the menu that displays U-Disk-File-List and Inner-File-List select the former, select the file and it then scans the file and then you get the "run" screen. If you get to a menu that has the three options View-File, Copy-File, Delete-File then you've gone wrong somewhere - unless of course you actually DO want to copy the file to internal flash.

Re: Converting to Mach3 it should be dead easy. If you look at the link I posted above it has the diagram of the interface card for the pendant. You'll see it's just a plain vanilla step/dir with I/O. If you start with Mach3 parallel port it should be as simple as getting a BOB and moving the labelled wires from the current card to the BOB.

Hi Stirling. I appreciate you looking into this for me. I am doing exactly as you say; select u disk, select file. Mine does it the other way round after this though. It gives you the run screen to set the speeds etc. When you ok the speeds it starts scanning the file (screen says checking file), that is when it counts up as percentage (takes ages for a 100mb file, 20minutes or so). Files above the memory threshold trigger the 'insufficient memory' display.
In order to look at the dsp program, I will need to hook it up to my pc, which will need to be running windows xp (more hassle). If nothing else works I will do this and see if there is a setting accessible from the pc to change the way it reads.
I have never found the view, copy, delete file option. It just gives me the choices you wrote above but once file is selected you get the chance to set speeds before it scans and spits the dummy out due to file size.
I can't help thinking the messed up cuts it made over the last couple of days are related to this issue. I am trying to eliminate potential sources of the problem. My last known good file (a small one) ran fine yesterday evening. So many blinkin' variables though.
Keep the advice coming. It's good to know that it should be possible.
As regards Mach 3. I will undoubtably convert it sooner or later. Sooner if I can't get this flipin' pendant working properly.
