What does

sudo mesaflash --device 5i25 --readhmid

report?
 

Do you have some documentation on the Sprint 1200 connections?
Just knowing the names is not enough to know how to connect them.

Good evening.  I am not sure if this is the right area to ask this question, but here goes.  I am converting a Novaturn lathe that has a Sprint 1200 (400) DC motor controller and I am using a Mesa 7i76U to handle the connections.  I have the steppers moving properly, the e stop and limits working properly but am very apprehensive about connecting to the Sprint 1200 because I dont want to damage anything.  Anyway, after days of reading, testing, and more reading I am finally reaching out for help.  Does anyone know the correct wiring to connect the 7i76 (TB4) spindle connectors to the appropriate Sprint connectors?  I need to be able to turn the motor on, adjust speed, etc.  The motor does not reverse.  The contacts on the Sprint are (1) +10, (2) MIN, (3) I/P, 4 COM, (5) RUN, (6) TACH, (7) COM.  Any guidance would be appreciated.

Technically that's more router type machine, mills are big heavy monsters made of cast iron.

Yeah I have both, the little 3 axis desktop thingy is good for testing concepts and moving around.
The mill stays put in the garage, mind it's only a little 120kg thingy.

ok my mistake i had/have the 5i25_7i76x2_2pd.bit in the 6i25

so my original post is still the same

thanks

Yes, its an old XZ lathe, a Maximat Standard. Quite comparable to the Myford ML7 actually.
Similarly to the ML7, the cross slide (trapezoidal) screw moves with the cross slide, with the nut mounted on the carriage. That limits the motor mounting a bit, as I would like to keep it simple. But if I limit this motor to Nema 17, I have a solution that works well.

Linear encoder feedback is actually on the wishlist as well, not only for CNC operation but also as a DRO when running it manually. I'd first like to get it set up with just motors with feedback though. If I get around to it, I'd also like to implement the linear encoder readout via EtherCAT if possible, as it seems like the most elegant solution when already using EtherCAT. The controller would neeed to run in LCNC on the computer in that case, which leads to a similar question as in the original post.

Fix the error that says signal not found, 9 times out of 10 it's a typo in either of your hal files, can't say much else without you posting the ini and hal files.

No need to guess,Then look for the an entry mentioning a parallel port, it's been mentioned a number of times throughout the thread

What version of mesaflash and LinuxCNC is needed for the 7i76EU?

Thanks

For future reference, is this also true of the P1 inputs -- are they also locked as inputs, assuming the default firmware?

Old computer failed to boot due to hardware failure, so I built a new computer. I was able to get the old config files off drive, but LinuxCNC errors at launch when I use these to launch on new computer. I didn't build or config the machine originally, so very new to the config files. Any thoughts on the below issue? If the card is the issue would it be worth getting a ethernet card as a replacement?

I'm wondering if the Mesa 6i25 is not working in new computer because it is not listed when I run lspci.
The two issues on the report I see are no parport which can be false error and
custom_postgui.hal:4: signal 'spindle-at-speed' not found.

custom_postgui.hal file:
# Include your customized HAL commands here
# The commands in this file are run after the AXIS GUI (including PyVCP panel) starts

sets spindle-at-speed true

when output type set to 2, the spindle is not moving at all.
 
when out put is 1, another strange thing, with command M3 S100, I directly got this: 
I ask 100RPM and get 3.3 rps hence 200rpm
I checked the spindle.0.revs and it's correct, when I do 1 full turn, it's correctly recorded. This is strange
 

Thanks -- empirical evidence agrees with you.
