Hello guys,

I bought a Deckel FP2A milling machine that I am planing to convert to LinuxCNC. Currently I am disassembling the machine to clean and inspect it.

The Deckel uses LS 904 glass scales. I seen other people use Heidenhain EXE modules to get a TTL signal for Linux, but my problem is that the LS 904 is not listed in the documentation that Heidenhain provides. Does anyone else have the same scales and found a compatible EXE module?

The scale has a 20um grid and 11uAss signal.

Thanks in advance.

My guess would be that any EXE box that accepts 11uA signals would work.

I have a bunch of these scales myself. I'm planning on building my own converters from sin/cos to incremental.

In general:
EXE is for 11ua
IBV is for 1vpp

The cost of new Heidenhain Interpolation and Digitizing Electronics modules are higher than the price of new glass scales and readers from other sources.

Thanks for your answers. The EXE 100 would be a good match, but I can't find any on eBay (Germany). I looked more into the 600 Series and they seem to fit as well. I am going to get three of those. Getting new glass scales is actually more expensive, since the 600 series are often on eBay (again in Germany) for a fair price.

I woukd also guess that the 600 series EXE cards will work. I don't remember what exact numbers are best, but be aware that there are different ones with different interpolation ratios. I think it's the 612 or something like that which have higher interpolation. I got the one with high interpolation ratio and now have .2 micron resolution with normal 20 um scales. I thik the interpolation rate was 50 on the ones I have. And the price on the good ones are not that much higher than the more common ones. So it's definately worth getting them!

And remember that your encoders will plugg dirrectly in to these cards, but you'd have to make your own solution if you make something yourself with IC-haus chips. And those connectors are not cheap! So very convenient and fast to get used EXE cards.
