Yes, 7i76e.

Awesome, generous offer, thanks! From what I hear Mesa boards are very robust so I don't anticipate that anything will fail with that system. But, it is a mission critical machine for their production.

I assume you're talking about a 7i76e board and it's being replaced with a 7i76eu. Last I checked on 6/27 the 7i76eu was 2 months out so maybe it's getting close. If something happens to your 7i76e before the 7i76eu is available I do have one in reserve in case someone breaks down.

If you have one working card you could choose the slowest/cheapest shipping option for
the other card Also both issues (damaged step/dir output or damaged spindle output)
are relatively easy  to repair if you have a nearby person with SMT repair ability
(the affected parts are known and inexpensive)
 

Good to know - I am in the EU though, not sure that is feasible here.

For simple isolated issues (like a step/dir channel failure or spindle issue)
It is possible to repair the card

Ok thanks. Looks like the new one is also defective then

Probably your scope setup
 Minimum step length on the 7I76E is one ClockLow cycle or 10 ns

The 4030 drive does require quite high drive current
so you may need to wire it single ended:

7I76E +5 to Drive STEP+, DIR+
7I76E STEP- to Drive STEP-
7I76E DIR- to Drive DIR-
 

No, the only differences between 7I76E versions is that the overvoltage
protection is better on the C rev cards and the field power regulator uses
a different chip. The spindle interface is identical.

When setting step 5000 5000 dir 10000 1000 the controller does not read the signal at all, the oscilloscope also the minimum signal it reads is dir 6000 6000.

After searching for more than a year or two I finally got hold of a replacement 7176E, as on my old one one of the servo channels stopped working.

On the 7i76E I received I see that it is HW Rev B (my old one was Rev C).
After inserting the new card I noticed that the spindle control doesn't work.

Is there a difference between these two revisions that could explain why it doesn't work?

I would probably set the step space and step length to 5000,5000
and dir setup and dir hold to 10000,10000 on that drive.

That is, double the minimum drive timings.

Ok, I increased the step time and set it to type 0, it works, but I set everything to 10000

Its most likely a hal file setting thats wrong: The step length

How can I diagnose why it's not type 0? Maybe it's the Ethernet cable's fault?
