I wanna note: It looks kinda professionally done, but its not. I'm in the luck of having a father in law that owns the place (he is a mason by profession) and i can use the place and the incredible useful overhead crane. Without that it would be impossible. For other projects i used the good old engine hoist in my garage, but for this machine it is just to small.

I will update as soon as there is any progress done.

1. Need to solve the guide rail problem
2. Ways need to be reground and scraped. Including the gibs.
3. Ballsrews need to be serviced
4. Milling spindle needs to be repaired
5. CLEANING

Yeah, sorry about that, made a quick change in the V2 version, and had a typo
that broke 7I96 input 0

EDIT:

Note that the 7i96sd_mpgp1 firmware has a different pinout on P1 and not a close match
to the common wired MPGs. I just fixed and re-uploaded the 7i96sd_inmp1v2 firmware
if that's more appropriate (and the  7i96sd_inmp1v1 firmware was always OK )

 

Hallo liebes Forum,

Ich habe die Lösung gefunden. Ich habe meine 7i96S mit dem file 7i96sd_mpgp1.bin von der mesa homepage neu geflasht.
Jetzt funktioniert alles wieder wie erwartet. Mein Ziel ist es mein Handrad auf P1 anszuschliessen, das müsste mit diesem file auch gehen.

Vielen -dank

Hello PCW,

I found a solution:
I flashed my 7i96s with the 7i96sd_mpgp1.bi file from the mesa homepage. Now everything works as expected.
My goal is to wire my MPG to P1, I think, this bin-file is for realizing this too.

Thanks a lot

Update:

So i took the machine mostly apart.

It is really dirty. I don't know what the pre-owners did with it, but dried up coolant is basically everywhere. Its yukky. It takes a lot of time to clean everything.

Linear guide rails on the Z Axis -> Scrap ( 2 out of 5 blocks are wiggling in the Rail) The rail is some special THK rail and is only sold as a set by Mazak. I requested a counter offer from a THK dealer... even more expensive.

The Y axis box ways are done. The lubrication system malfunctioned and the way wipers failed over the years. Already brought it in for regrinding. After that it needs to be scraped, which i am able to do. I lack a lot of experience in scrapping but its a "simple" box way and no dove tail ways.

Same goes basically for the X axis. Lube system got plugged up by failing way wipers and even the hardened ways got damaged. -> Regrinding.

Ballscrews:

Z Axis ballscrew is in good condition, but has no preload anymore.
X Axis ballscrew is in good condition, and still has preload.
Y Axis ballscrew feels a little bit crunchy... the balls need the be replaced and checked again.

Milling spindle:

The taper is shot and needs to be reground. I assume the bearings are also in no good condition. This repair also needs the be done professionally. 

The good news:

I fixed my temporary encoder capacitor solution with a proper super cap. I even upgraded it to a 1.5F

Good Morning,

I've installed Probe Basic and continue to have an issue with parameters not being written to the .var file. Anytime a value is updated via Probe_basic ui, a "File not Open" error shows and no changes are made to the .var file. Parameters entered via Gcodes work fine. For instance, SET TOOL TOUCH OFF POS generates "File Not Open" error, but MDI g30.1 works fine. The sim version works fine. 

Terminal shows: emctask.cc 68: interp_error

I am running:
Debian 12 Bookworm
LCNC v2.10
Current version of Probe_basic and QtPyVCP
installed sable APT version 

Any help would be greatly appreciated. 

Thank you,
Sean

  

Hello PCW,

A few days ago i flashed my 7i96s with the 7i96sd_inmp1v2.bin file. Flashing was without error.
Since then, the X-axis-homing does not work anymore.
Homing of y-axis and z-axis works fine, as expected.
I would be glad to get your help to solve this issue
Is there a way to get the 7i96s in the state before flashing ?

Tanks a lot

Hallo Zusammen,
Ich bin neu im Forum und wende mich an euch, da ich den Fehler beim Referenzieren der X-Achse nicht finde.
Meine LinuxCNC miz 7i96S hat wunderbar funktioniert, bis ich die Karte mit dem file 7i96sd_inmp1v2.bin geflasht habe.
Ich habe nur den flash gemacht, an der pncconf usw nichts geändert. 

Die Y-&Z-Achse referenzieren nach wie vor wie erwartet, die X-Achse fährt in die falsche Richtung los, d.h. vom Referenzschalter weg,
wenn ich den Schalter von Hand betätige fährt X einfach weiter, der Positionswert ändert sich nicht auf 0, zählt einfach weiter.

Bei 2 Punkten bitte ich um eure Hilfe:
- Welche Ursache kann dieses Verhalten auslösen ?
- Wie schaffe ich es die 7i96s in den vorigen Zustand zu flashen ?

Über jeden Input freue ich mich, den bin-, hal- und ini-file habe ich abgeängt.

1 encoder, nur ein.
7i83 hat kein encoder eingange, 7i85 oder 7i85S soll 4 encoder eingange habben.
-
Ich wurde die 7i95T mit 7i83 nemen, fuhr mehr IO noch ein 7i84 nemen, oder 7i73 fuhr die konzole ...

it's possible...i measured 24V on the output pins.....these lines look different then when the machine was last operational but i had ChatGPT produce these...they don't seem right to me but i don't know enough...my board is a 7i76EU so i was thinking of replacing 7i76 with 7i76EU......if i comment these lines out the z axis brake doesn't release...

therman@Debian-LinuxCNC:~$ halcmd getp hm2_7i76.0.7i76.0.0.output-01
TRUE
therman@Debian-LinuxCNC:~$ halcmd getp hm2_7i76.0.7i76.0.0.output-00
TRUE
therman@Debian-LinuxCNC:~$ halcmd getp hm2_7i76.0.7i76.0.0.output-02
TRUE

Is it just about homing sequences? Or do you need to keep a fixed ratio for the axis?
