Hallo,

schön, dass du die Frustrationsschwelle "verschoben hast"
Ich vestehe nicht ganz, was du verändern möchtest. X-geht ja "eigenlich" immer von "links" nach "rechts" und y immer "vorne-hinten".
Soll die Beschriftung am Bildschirm getauscht werden?
Die Zuordnung der Antriebe könnte man ja einfach durch umstöpseln der Motoren erledigen, oder in der *.hal die zugehörigen Mesa-Ausgänge vertauschen.

Gruß Timo

I wish I had found Marks saga before I finished my Maho MHC700 restoration. Not an obvious place to start looking for a Heidenhain controlled machine. My machine has a TNC 155 retrofitted and you probably have read about it's rebuild on Marks thread. Your TNC 355 is very similar. It just has a bit more memory and speed. So it has a few more machine parameters tacked in the end of the TNC 155 list and probably runs a bit faster.
The one really lucky break I got was the Heidenhain worked perfectly first time. All I had to do was load in the machine parameters and swap it to English. Fortunately I had them on paper tape and hand written in the manual.
But that situation didn't last. Recently it started to get some fold back at the top of the BE411 monitor. Not the end of the world, but I couldn't read the line number in graphics mode, making testing programs a bit difficult. The problem is almost always the electrolytic capacitors so I read up on how to not kill myself changing them. Disconcerting things like putting one hand in your pocket whilst shorting the 22000 volts on the plug on the display tube with the other, so you don't draw the voltage across your heart if you mess up.
There are about 25 of them if you do all of them like I did, and there a few difficulties and traps to know if you want to try it on yours, but it came up perfect. Crisp and clean without doing any adjustments. About $60 Australian from Farnell in the UK. 3 days deliver to Australia. And the capacitors are smaller, have up to 5 times the life even at a much higher temperature rating.
In hindsight it might have been easier to do that on yours to debug the circuits then go to LinuxCNC.
The problem with the Heidenhain is you have a TI processor of about the same era an IBM PC AT with an Intel 80286. 16 bit and about 8MHz. And you are limited to simple pocketing and pecking.
With your setup you have the advantage of updating you PC forever and a wealth of open source programs. To get to the next step I'm going to have to get familiar with Fusion 360 and drip feed. Heidenhain has a nice serial coms program that works for all the machine they ever made Fusion 360 has a post processor file that works for my machine. I've been doing my modelling in SolidWorks for the last 30 years so it's not that big a step.

BTW. On mine, once the 220 volt power is latched on by 19K1, it goes through the 3Q1 circuit breaker, then to the  3F1 pressure switch on the hydraulic pump, then back the the hydraulic pump contactor coil 3K1 and runs the pump. The pump run is very brief as there in no hydraulic accumulator on my machine. It runs a lot longer to release both chucks or the CNC rotary table. The Vogel lubricator also runs straight from 3Q1 also and is actually powered by the 220 volts. So it does a lube cycle every startup, then goes to timer based lubrication cycles. So a dumb system not controlled by the CNC controller.

Cheers,

Instant fix. Tommy, thank you. I have been slamming my head against that for days.

I appreciate your response, but I am not sure we are talking about the same thing.

Can you elaborate on how a potentiometer would work as a switch?

So appreciated! I will go take a crack at that right now.
I disconnect ALL the power! always.

Do you already have the switches?
If not, use potentiometers, cheaper, easier to wire, and linear regulation/range/etc

I tried reversing the motor phase connections on one driver/motor and the motors still both spun the same direction.

One winding ONLY, not both, and not phases.
Single phase, one winding, two wires, that is the only thing you need to change for it to change direction.
Edit:
NEVER while the drive is powered!!!

Is it a subtle difference? I don't see a difference in zooming with your changes.
It certainly didn't hurt anything ti have it in.

LIkely the answer is no, hope I am wrong.

I am using linuxcnc 2.7.15 breakout board with printer cable
My X axis has twin rack/pinion drive, motors need to turn in opposite directions. Modifying HAL is beyond me.

I tried reversing the motor phase connections on one driver/motor and the motors still both spun the same direction. Should clarify, both CW and CCW but in sync not opposite as I need.
I have both x axis motors connected to P2 P3 not ideal I realize.

I wonder if it is possible to rearrange the control connectors to reverse one motor? I have not messed with this. The jumpers bringing power to pul+ Dir+ and Ena+  puzzle me. Ena- goes to P2 and Dir- goes to P3.

Thank you.
David

EDIT: I ordered and received binary switches, after some contemplation. They only output in binary - no pins for switch positions - and seem to be the right tool for the job in LinuxCNC with a Mesa 7i73 card. Time will tell.

Weirdly, Mouser doesn't even include this in their "Coded Rotary Switches" section, so finding them was down to luck. The pins are super delicate, so it's pretty clear it was meant to be mounted directly on a PCB. I'm not currently sure how that would work in a DIY console, so I still might get some little breakout PCBs made.

Lorlin BCK1006 pictured below, though BCK1008 would also make a lot of sense, maybe even more sense. It would have more closed circuits than open circuits in the most oft-used positions.

EDIT: I added a graphic to illustrate the alternative that I found during this discussion. A mux switch seems to be the right tool for the job, but existing products, and documentation combined with illustration of their function are basically nonexistent. This is my attempt to create a resource for future me and others to refer to when creating their own mux selector switches.

I am moving from EdingCNC to LinuxCNC.

Sorting out the MPG/pendant, I thought I could just use 1k resistors like in the attached image of the EdingCNC manual, with the 7i73 analog input sensing the resistance value, but I can't seem to find any examples of anyone doing this in LinuxCNC. Here is a screenshot from the EdingCNC manual, that shows what I was planning to do:

@roya
I gave that same 6.12-rc7 image some more test , trying to pinpoint where the glitches come from , for the sake of learning , an i do got this dust collector opi4 ...
Stumble upon the linuxcnc-rio guy , wow , still got 80 pages of post to read + his git .
Back to your 6.12rc7 , tried the 3 deb packages you've post on another image , the headers deb is corrupted by te way .
With same -1Gb img , stopping some unused .services , I do get ''stable'' shutdown now , isolating 3 last cores ,
no impressive latency results of course , but a usable fast enough(no lag) jwm desktop ,no hang ,no oo's , i'll hook up the 7i92 to the bob with it , the opi4/your 6.12rt as a ''one at the time'' purpose job and come back , after reading more about the rio .
Kernel 6.12 is young , worth testing it , opi4 may not be the best sbc candidate , not to mention xulong support , or worse their forum !!!
Thanks again , no rush ,i'll be back .
PJ
edit ; still some random kernel panic on shutdown ,i will try recompiling the dts for opi4 to see if it goes somewhere..
