DSP Array function

[Russ]

Hi,
Has anyone successfully used the Array function in PHCAD 4.45 to fill a bed sized sheet and cut?
I can Array a part and cut a few but nothing like the bed size without getting the Y flop over error..
I can cut a bed sized square so all appears to be set up properly

Any help would be great,

Thanks

Notice where the main item ends up in relation to the copies. I think you need to set your origin at the most outside corner of the array. I have used it but can't remember the specifics. May be able to test and report later today. If not, it will be this weekend.

Hi Tim,
Thanks for your reply and indeed your setup guide which I did make use of, very good of you to take time to do such things..
Regarding the Array setup through trial and error I can get multiple copies but only in the down direction, if I set the origin at bottom left of table, as I do with single cuts and all works fine, on the PC all looks good in the table display but on the machine I firstly get the Y slopover error (Box) and if I start anyway it'll cut a row then try and move down, which of course it can't.
The only joy I've had is setting origins to Up Right, ignoring the PC display cos most of the parts are shown off the table space (above and right of the master part, only way they go), the machine will then cut the parts by rapid to bottom left then work row by row back up the table..
All in all the PC will only Array right and up and the machine will only cut right and down.. again single cuts are fine nothing mirrored etc..
Still fumbling with it, any thoughts would be great..

PS, I've posted elsewhere the error in the quickstart wiring guide regarding stepper connection, may be worth noting on your guide for others perhaps

Another PS, have you had any joy with "If Blowing"?, no outputs changing for me..

Thanks for your time,

Russ,

I did not get to it yesterday. I will try to test and document the array functionality this weekend.

Not sure what wiring you are referring to. I'll try to find it.

There are other posts about If Blowing (or If Cooling) on the board here someplace. I'll look as soon as I can. I have never used, so have not experience to offer. If there is an issue, I can probably verify with the o-scope and then document.

Hi Russ,
Did you get the array function working ?

I haven't tried it yet as I just mainly cut about 4-6 things and orient them myself to cut down on waste.
I know when I get the" Y Slop" error I haven't set my limits or origin correctly in all of the settings after I reset from the rotary attachment which works back to front from my table setup.

When I first had this problem and after adjusting the acceleration to 30,000 ( thanks Tim ) I found I had the limits wired wrongly and had to go back and set them all HIGH as that was how the laser was triggered. They are interconnected and need to "see" 5volts for the DSP to work properly. 2 of them were wired up NC and 2 were NO. Stupid mistake on my part!

I went back and wired everything the same way and rechecked the origins all were set the same as well and then I had it working. For me, setting the limits was probably the hardest part about setting up the DSP because it is so configurable.
High needs 5V and low needs 0V to work. You can't mix these up. I think the board has a jumper for High or Low as well and you may need to check that too.
