I'm having some intermittent problems with my Dual Z setup.

The heads always swap when commanded, but the offsets don't.  Sometimes Z1 will start routing using the Z2 XY offsets and vice versa.


Some files are worse than others.  Some files run flawlessly.  I'm assuming it is a problem with the Custom XML file that came with the controller, but I have no way of knowing.

The controller is an Ascension Revision 4.  The company is no longer in business.

Not familiar with these machines at all, can you post a few pics, the xml and maybe some code that you have that works and doesnt work.

Thanks Hood,

The Machine is a Shopbot PRT Gantry style router.  The Ascension is a controller using a Jim Cullins designed board with 5 G202s (2/X, 1/Y, 1/Z1, 1/Z2).

I'll have to run some more files to figure out which ones are solid and which ones are buggy.

For now, here's the xml file.  Hopefully the problem lies there.

The commands for swapping heads are M101 (Z), M102 (Z2).  The commands for turning the heads on are M7 (Z1), M8 (Z2), M9 (off).  I don't see those in the xml file, but have no understanding of this system.

Sheldon, post some code your haveing trouble with. Notes at points it gives trouble would be nice as well.

This is the last file I ran that was making me nuts.

It starts with a Z2 move.  Consistently it would start routing using the Z1 offsets.

Sheldon, also look in the macro folder then in your profiles folder and attache the M101, M102, M7,8 and 9
Hood

Thanks Hood.  The M7, 8 & 9 are just output triggers.  They are working fine.

Here's the M101, 102 macros.

 will also need your screenset

We're getting close, I can feel it   Thanks for the help with this.

Well I have run this quite a few times and so far its swapped the XY offsets each time. What version Mach are you running, I will load that and see if I can repeat your problems. Its after midnight here so it will probably be tomorrow before I try again, if I dont respond bump the thread to jog my memory
