Retrofitting a 1986 Maho MH400E

Andy, your horizontal mill fetish is showing That looks like it has done little work.

What is the next project for your MH400E ?
Bolt to the ram high speed spindle - Plate to lower table for more Z height - B axis with C axis for true 5 axis machining - digitizing the Haimer probe for direct input into LinuxCNC ?

The most urgent project for the Maho is welding up a stand to mount the shock mounts, and at the same time allow me to easily pick it up with the pallet jack.
Probably the next bigger project is likely to by an NC fourth axis. But no urgency on that.

Hello Hedenhain experts. I have access to Hedenhain EXE 610C converters. Can anyone tell me the difference between these and the EXE610D. The 610C does have the correct 5 fold interpolation needed to keep my machine at 1 micron resolution. Cannot find specifics on the 610D. My guess is differences in connectors?

I never really got a good handle on Heidenhains unlimited variations of EXE model numbers. I think most have M23 connectors on the scale side, but the output side can be nearly anything.

Is this Attachment - PDF - any help ?

Those are later models than mine. It doesn't list the 602D' of which I have two different models.

Maybe this ?

Hello people,greetings from Bulgaria.Five months ago bought Maho MH600C with idea to retrofit it with Linuxcnc . It was in not working condition because of spindle drive failure. There was some dead operational amplifiers and capacitors in the TRK6 drive, but after their replacing spindle (and the whole system)works properly. Yesterday arrives the mesa set 5i25/7i77/7i84 .And now -the first problem:the linear measuring scales are Philips. Can someone give me solution how to adapt them to mesa 7i77 ?Or just to replace them with new ones? I found a some kind of converter offered from local engeneering company ,but i dont know will it work? www.bulgarianindustry.bg/assets/cms/Imag...verter_datasheet.jpg
The topic is very helpful ,and is one from the reasons for buying MAHO!

Hi,

Sascha (linuxcnc-ethercat) has done this a few years ago with an MH600C.

github.com/sittner/lcnc-mdsio

unfortunaly the used fpga spartan 3 board is no longer available.

But depending on your electronic skills, you can use or mod the "maho-encoder" board and implement the
phillips interpolation with an mesa fpga. (i am not firm with the mesa boards, but if there is acces to enough analog pins in theory this should work)

The function of the scales is documentaded and also the vhdl files for phillips are on github.
