​I'm currently working on an upgrade project for an Emco Turn 55-II lathe located at a local school.
​I’m looking for the wiring manual or electrical schematics for this machine. I’m not entirely sure which of the two versions it is, so if anyone happens to have documentation for either (or both), it would be a huge help so I can compare them and move forward with the project.
​Any help or guidance on where to find these would be greatly appreciated!
​Thanks in advance.
Please excuse any mistakes in my English, as I am using a translator to write this

I have a resistive touchscreen and this works quite well.

Good morning everyone. After several tests I had to leave the machine to the customer with Debian 10. Believe me, I tried everything. It seemed to work with the refClockSyncCycles setting to 1, but sometimes the motors, when the PC was started for the first time, made noise. Turning it off and on again is fine and when it works well, it works well for a long time. I even tried Debian 12, the Git ISO and ethercat 1.6.3, but even worse than Trixie. I put back the Debian 10 HD and ethercat 1.5.2 and it still works fine, even if at first glance, in addition to the fact that with Debian 10, the drive values ​​are read instantly when the PC starts, while with Debian 12 and Trixie, you have to wait a few seconds. And in my opinion, everything starts from this problem. I set latency-histogram --nobase --sbins 1000 --show, stressed the PC, with gear, opening the browser (not connected), moved windows, opened librecad etc., but Debian 10 has maximum and minimum latency half of Debian 12 and Trixie, same PC. I think the problem is between the RT kernel and the Ethercat version. For example, I tested the Debian 10 pins with Ethercat 1.5.2. The pll-error value oscillates between -2200 and 1600. The pll-out pin has a fixed value of 1000 or -1000. Why don't we try installing Ethercat 1.5.2 on Trixie, so as to understand if the problem is on the kernel or Ethercat side. I think that on the Icec side, there is little to do. Yes, we're certainly trying to optimize, but the main problem is latency and jitter stability. I remain available. Luca, I wrote to you privately, but you haven't responded.

Hey, folks here literally saved my ass from a disaster so I'm passing it on.

I have a 7.5hp old Columbo spindle that I know little about besides:
(a) Resistance is 1.8ohm consistent across all 3 windings.
(b) Its from 1994ish, and serviced in 2004.
(c) Manual change, and the mechanism to hold the spindle works.
(d) CAT40, insides look good, threads look good.
(e) 18000rpm (I think)
(f) About 80 freedom weight units (says so on the maintenance invoice from 2004).

Free.

You pay shipping. Its located in southern New Hampshire in Freedomland. 
I will post runout or vibration numbers once I get set up to measure everything.
Do request any info you need, and I'll update it here as I measure stuff.

I'm trying to set up linuxcnc on an old motion master bridge. Reusing the brushed servos and 4 amp. drives. Adding 4 pulse train Yaskawa servos/drives (this is the upgrade) to swivel head and rotaries. I'd very much appreciate someone willing to take a few calls and guide me along so I can get help or quick opinions when in a pinch. I've so far managed to covert a 480V machine to 220V. 

Something I'd love is a 7i77u board (just borrow it for a few weeks if you have one to spare). I just don't know enough to understand if I can use 7i77 boards that are immediately available. That's my immediate next step.

They are out of stock and I'm hard up for time. Wife gave me permission to start a project with a machine that is the size of a room, and then, a few weeks later, tells me the whole family is moving to a place that not much bigger than the room the machine is filling up. FML. 

Make stuff and prosper.

 

Oh, I had forgotten about that. I will try if that works. Thanks for the idea.

That looks cool, but I added physical encoders for Jog, feed and spindle overrides, so I never use the buttons.

Since there are two Hall sensor triggers on X, do you get the same errors homing off each?

Ihr seid klasse!
Mit eurer Hilfe habe ich folgendes rausgefunden:
Unter P04.03 kann ich mit dem Wert 03 für das Relais 1 folgendes einstellen: "3:Arbritrary frequency arrival Time,
Relay=ON,Related to P02-10 settings" --> Unter P04.04 ist das für ein Relais 02 einzustellen. Dieses Relais gibt es aber (bei meinem FU) gar nicht.
P02.10 war dann nicht so leicht zu finden.: P02.10 Arbitrary Frequency Setpoint 0-400Hz 
Zuerst hatte ich dieses Manual: bulkman3d.com/wp-content/uploads/2019/08...Wk1gLYu__4-sQemlJnOc
Da fehlten aber einige Einstellungen. Dann habe ich noch dieses Manual (nur die Einstellungen) gefunden: bulkman3d.com/wp-content/uploads/2019/08...Wk1gLYu__4-sQemlJnOc
Jetzt schaltet sich das Relais erstmal ein, sobald sich die Spindel dreht. Ich denke, dass ich mit P02.10 da noch was besser einstellen kann.
Nun schaltet das Relais die Kontakte CM1 und NO1 durch, sobald sich die Spindel dreht. Ich denke, dass ich den Anschluss an die Mesa-Card (+24V auf CM1, NO1 an die Mesa-Card) und dann die Einstellungen in der HAL (siehe in der Antwort von 0x2102) dann hinbekomme. 
Vielen Dank!

Currently the value of the sliders can only be adjusted by the +/- buttons. This makes it impossible to change those values quickly.
Here are two implementations which opens a bigger slider with the possibility to drag the slider.

What do you guys think of those two versions?

The previous owner installed a magnetic encoder on the X axis. I did not disassemble it, so all there is to see is a thin cable coming out.

I installed a glass scale on Z. I will make photos tomorrow, there is perfect space for it behind the X-axis motor mount. The installation was really easy.

Oh, and to “home to switch (hall switch) and then to the next encoder count” that is what I did initially. That way I got about 0.4 mm variability on X.

I don't think you need to wire the motor encoder A and B signals in to LinuxCNC to try it. It is a standard LinuxCNC option to home to switch (Hal switch) and then to the next encoder count, which you already have wired in.

I am interested to see how they did the physical installation of the linear encoders. I considered adding them to mine, but didn't.

Found another bug/missing feature in tp1. Hitting feed hold sometimes breaks planning, I guess the remaining length of current segment is too short to calculate using ruckig?
Ruckig planning failed (first attempt),
Back to tp 0
feed_override: 0.330000
max_vel: 132.000000
cpos: 380.077500, tpos:
380.133525, dx: 0.056025
cvel: 33.000000, tvel: 132.000000
cacc: 3000.000000
maxa: 3000.000000, maxj: 120000.000000

I don’t think the linear scales are at fault. I tested them over the 20 mm range of my longest indicator in 1 mm steps, and that is flawless for both axes. I also had the axis move over nearly its full range for 5 minutes at rapid speeds and then come back to the indicator, again, no measurable deviation.

To test the motor encoder directly, I would have to solder them in, and I cannot imagine that this will be better, as I already use the index from there. But if I don’t have any other options, I may as well try it.

I can make some pictures tomorrow, do you mean the mechanical installation on the machine or the wiring, or both?

You are making great progress. Took me a year to get that far

I can't say why it is not working as it is, but I have no linear scales, so my homing is just the home Hal switch and then fine tuned off the motor encoder index, and that is rock solid. Could you ignore the linear scale, and home the same as mine (which I think is original Schaublin)?

Please upload some pictures of your linear encoder installations.
Cheers,
Mark
