Awesome advice! Thank you for the guidance - it's exactly what I needed!

OK, so the cute little Atom board is a no-go. I also have a Supermicro board laying around, with a 6-core Opteron on it. I figured it was overkill - but apparently not!

Yes, Pico Systems' boards are parallel port. However, they are not like typical parallel port breakout boards. They are more like Mesa boards - where the processing occurs on the board. Given the fact that Jon is one of the "OGs" of the LinuxCNC world and happens to be local to me, I've debated about whether to go with the standard Mesa board or a board that might come with more personalized service from the engineer who designed it. I don't want to spend a money on stuff that's already outdated, though.

I will reach out to Mesa, and see what they have to say. Their site has a lot of technical information about their boards, but it's difficult for a "newbie" to interpret.

I was hoping you would say that about a touchscreen. That will make the system a lot "cleaner." Having a wireless keyboard tucked away is a great compromise.

Encoder 2 on the 7i85S is used for the spindle and is actually single-ended, but it's still working fine. So I guess I’ve been lucky there, considering the damage on the board.

I’d really appreciate it if I could get two replacement chips, if it’s possible to have them shipped to Germany.

I meant the BOM for the missing parts. As in all motors, controller boards, cables, router spindel etc.
Might need quite some help with that, I guess

As for the weight, they seem to got there a bit of mixup, I guess the apprentice maintaining the site, missed some spots after c&p . IN the end, it will be delivered on a palette anyways..

Sadly the german punctuality has gone big style (the trains are 70% in time at best), but in exchange we got even more bureaucracy.

BUT!!! metric system!

For the parallel port output pins 4 and 5, you would first check
the pinout as  shown previously, this shows that DB25 pin 4 is GPIO 47
and that DB25 pin 5 is GPIO 49

PIN                             GPIO
P1-01/DB25-01          41   IOPort             
P1-02/DB25-14          42   IOPort          
P1-03/DB25-02          43   IOPort       
P1-04/DB25-15          44   IOPort     
P1-05/DB25-03          45   IOPort 
P1-06/DB25-16          46   IOPort     
P1-07/DB25-04          47   IOPort         
P1-08/DB25-17          48   IOPort         
P1-09/DB25-05          49   IOPort    

so

net spindle-cw      => parport.0.pin-05-out
net spindle-ccw     => parport.0.pin-04-out

become

net spindle-cw      => hm2_7i95.0.gpio.049.out
net spindle-ccw     => hm2_7i95.0.gpio.047.out

But there is one more step needed, because GPIO bits default to inputs at startup,
you must set these GPIO pins to output mode:

setp hm2_7i96s.0.gpio.049.is_output true
setp hm2_7i96s.0.gpio.047.is_output true

As far as the connections below  go, they are no longer relevant,
because both the PWMgen generation and encoder counting would likely
be done in hardware:

net spindle-pwm     => parport.0.pin-01-out

net spindle-phase-a <= parport.0.pin-10-in
net spindle-index   <= parport.0.pin-12-in

Note that this will only work on stock 7i95t firmware or 7i95t_5abob firmware
if you disable the stepgens on DB25 pins 4,5 and on.



 

I am a slow learner... yes, the plug was the problem....

 

One phase disconnected, but loosely held in contact by the wire. I cut off the old ferrule, reterminated it with a new ferrule and now the machine is getting all phases.

It is still not clear to me whether this 7i84 can be saved with replacement NCV7608s or whether it is trash.

 

I will order a 7i84u for the Maho, but if this 7i84 can be rescued, I would use it in the Schaublin, where I ran out of 24V outputs, and bodged switching chinese relay boards with 5V outputs.

I'm not really surprised that this isn't related to my file, as I created it the same way I always do. I finally got it to load, but I'm not sure how. I tried kernels 6.1.0-28 and 6.1.0-32. I also tried 2.9.4-19-gd3a1da65b7, same result as with 2.10.0-pre0.
Now I have the same issue with the next file.

I will try on another hardware

Hi

Attaching the hal file I used with parallel port.
Please guide how I can connect the  spindle and encoder on the 5ABOB with 7i95t board. Upon checking pin file I can see PWM on pin ! and pin 4 (Step) and pin 5 (Direction)  and inputs on 10 and 12 pins for 5ABoB for the 7i95t mesa board, 

addf pwmgen.update servo-thread

Please help!

It is a CEE 16A five pin. No changes on the wall, socket or cable. The MAHO has been working without wiring change from this socket for about 6 years.

Yes, neutral is wired in, but unused by the machine. Since the original Phillips PC used 110VAC generated by the 6T1, I wired the LinuxCNC PC and monitor into the same service.

Okay, this got weirder. I just went down to the machine,  manually switched off 1Q1 (I misunderstood that as Q1), plugged in and switched the machine on (with Q1, the main power switch), and PC powered up normally. Switched Q1off, reset 1Q1 to on, switched the machine on again, and it again powered up the PC normally. measured 114VAC between pins 150/151.  I could see from the Mesa LED's that the 24VDC rail 204 was also powered. I changed nothing other than waiting a couple of hours and plugging / unplugging the socket a couple of times.

Writing this, I just realised I need to open up that CEE plug on the machine cable, and see if I have a loose connection in there.

That wire is on a 5V regulator pin, so maybe related, hard to tell.

Yes, NCV7608s are obsolete, we do have spares if you need a few.

Thanks, Tommy.
The shop is heated and very dry, especially during the German winter, so moisture is probably not the issue.

Picture 2, that looks like arcing across those two parts, moisture can do that, but the rest of the boards look like there is no moisture in quantities to cause that.

With Q1 open, what do you have between L1,L2,and L3?

Is the neutral wired on the machine?
What connector is used at the wall?
Was that connector or the wall socket changed before the incident?
-
Assuming using industrial 16A or 32A plugs, they can easily be miss wired by switching neutral and one of the phases, be it on the wall or on the machine plug.
When no neutral is used, usually not much happens, but when neutral is used that causes ... things to happen.
Mentioning this as it happens a lot where i live.

Does anyone use jmc integrated servos with a 7i77?
I know they work with pulse/dir but in the manual they mention some kind of external analog instruction, but nothing about +/-10v.
Or is there any other other possibility to drive them with a 7i77?
