501 dsp pendant large files problem

But that's not the answer to your question - he may *say* it BUFFERS but that's exactly what it isn't doing. Buffering means that rather than loading ALL the data from the stick to internal memory and then running it (what they call "internal"), BUFFERING (in this context) means it should load "some amount" from the stick to internal memory and then as it works through it it loads more as needed until the job is done (what they call "external").

Yes, thanks stirling, that's what I should have said had I engaged my brain better, buffering is what you said and it does allow memory in the pendant to be less as it's moving the file in smaller blocks.

Thanks EC but what you said originally about the 128 vs 123 is surely also correct. I expect the "importer" has an excuse for that too. Probably something like Ah... but USB megabytes are bigger megabytes than internal memory megabytes so that's why 123 won't fit into 128. Ah right - thanks...

Yes it's puzzling me. I agree Mach 3 is the way to go but the machine came with this pendant so I will try and make it work for now if I can.
The file is 123mb (an other is 105mb, neither run) and the internal memory of the pendant is 128mb so I'm not quite sure where the missing storage space has gone.

If anyone could convert my router to Mach 3 for a reasonable price I would defo be interested. Likewise if anyone could boost the memory of the pendant.

I am currently trying to circumvent the issue by dividing the cutting file into parts, to machine seperately on the same workpiece ( a pain in the arse). I have encountered another issue that's baffling me. Using the sub-segment facility in Deskproto, the finish file doesn't seem to coordinate with the roughing file. i.e the finish pass cut is cutting too shallow and then too deep. It vaguely resemble the roughing pass (I left a skin of 1mm to take off with finish pass), but is out by +- 5mm. I have double checked the origin and z level zero and it's all good. I am doing another sample as we speak to see if the same problem occurs. I am wondering if there is a bug in the sub-seg feature of Deskproto or whether I've overlooked something obvious. I'll keep you posted.

Oh crikey. It's all gone tits up now. I was cutting a roughing file on a 3d relief. It has 40mm depth which the router was due to cut in 2 x 20mm passes. When it got to the end of the first pass, instead of moving back 500mm to the origin to begin the second pass, it only moved back around 30mm and started the second pass in totally the wrong place. When I stopped the program and returned to origin, it had set itself a new origin where the second pass started. Rats!

So, something is amiss. It could be one of several things;
1)in trying to find how to run large files on the pendant I inadvertently pressed 'format' which deletes all the settings on the pendant memory. I reset them but may have missed something.

2) deskproto CAM has a bug in the sub-seg feature perhaps.

3) My new laptop which is running the CAM is messing it up. It is being replaced under warranty tomorrow as it's playing up.

I am going to try cutting a last known good file which should help identify whether it's the pendant or the file. Any advice much appreciated.
