Problems with Lichuan Ethercat servo drive

Category: EtherCAT

Has anyone solve "the start lcnc before plug in ethernet cable" issue yet?
i have the same thing but my driver are lichuan closed loop stepper CL3-E86H
I got it to run but still have to do the ritual every times I turn on the machine

Hm, seems to me that the recorded (blue) path deviates quite significantly from the displayed smoothed tool direction path.

Nur einfach die zwei Zeilen in der ini einfügen wird nicht reichen. Du müsstest 'Probe Screen' auch noch installieren:

für linuxcnc 2.8 könnte das hier helfen:
github.com/linuxcnc-probe-screen/probe-screen-ng

für 2.9 schau mal hier (das ist dann aber wirklich nicht mehr anfängerfreudlich)
forum.linuxcnc.org/49-basic-configuratio...obe?start=650#277215

Alternativ mal die QtDragon GUI ausprobieren, dort ist Probing schon mit eingebaut.

Ok,

Now it follows the tooldir path.

spindle doesn’t work

So that would indicate that the digital inputs need to be connected to COM rather than +12V.

I that case you can try to connect FWD to En+ and COM to En-.

If you need to reverse the spindle then you will need an extra relay that at rest connects En+ to FWD and when energized connects En+ to REV. The relay coil is driven by DIR-.

Category: Basic Configuration

I do have a panel where I can switch between manual and automatic. Was keeping it always in automatic mode.
Unfortunately, I've no documentation from this VFD.

I add another short between COM <=> REV and now the spindle starts rotating going to the maximum speed. Not bad, now I will return to the Mesa card wiring but now keep COM <=> REV.

Ok now i had a look back, see if the VFD has something similar to "remote" and "local", where local means control only over the built in keyboard and remote means control only over the wires.

and making a short on AVI <=> +10V as well FWD <=> +12V.

Since I see no other enabling input on the image of your VFD it is most likely a parameter setting issue in the VFD itself. My suggestion would be to have a look in the VFD manual. Usually there are parameters that need to be set to select the function of the analog voltage input.

Not yet, VFD's do require another signal to enable the VFD, usually named fwd or run, and if reverse mode is required there is also the rew or dir pin. Se the VFD manual how those signals should be triggered.

Getting started with 6i25+7i75+7i85s

Category: PnCConf Wizard

If i remember correctly, 7i85S has 4 stepgens and 4 encoders and a smart serial, and Argon drive does work with step/dir signals, so that is all taken care of.
7i75 should be a break out board with isolation (again if i remember correctly), so it can be used for other signaling.
This might need a firmware flash, although any existing firmware that has 7i85S in the name will work, so do try the included firmwares on the downloads page of mesanet.com
With Mesa any functional pins like step/dir, PWM, encoder counter, etc can be used as normal input or output pins if those functions are not required in hal.

spindle doesn’t work

Category: Basic Configuration

I made a simple test. Removing all wires from Mesa to VFD and making a short on AVI <=> +10V as well FWD <=> +12V. If I'm right the spindle should start right after I power the setup. But the spindle didn't start. Is my understanding correct that the VFD is broken?

G64 causes the processing acceleration to slow down

Category: G&M Codes

What is the required part tolerance?
If it can be 0.1mm then
G64 P0.1
Should be much faster
Or if doing decorative stuff, even G64 P0.3 or more should be OK, and much faster to run/finish.
0.01mm is very high tolerance, even metal fitting parts can deal with a bit more tolerance.

Dear gods, I've got the cards mentioned in the subject, and my purpose is to run a lathe with:
- STEP/DIR steppers for x and z axes
- quadrature linear encoders for x and z axes
- Argon servo drive to run the dc spindle motor
- a stepper, a solenoid and an absolute encoder for a tool carousel (although this one might be easier to control with a separate microcontroller?)
- relays for coolant and lubrication pumps

I've found that PncConf does not have the firmware option for my selection of cards, and now I have little clue as to how to proceed.
Why I'm in such a pickle is that I had a friend pick those boards for me, but later, he has become too busy to help me with setting them up.

So, I suppose my question is what should I do? Money or sunken costs are really not an issue. If I should buy new cards that are easier to setup, or pay someone to guide me, then I will.
Oh, and I do also have a 7i73, but no panel or pendant built or even planned yet, so I'm not so worried about that one. For now, I will be a happy man if I can just get the machine to run at all.

G64 causes the processing acceleration to slow down

Category: G&M Codes

Huh weird.

Someone more knowledgeable will probably step in. The only thing I can think of is the acceleration set the same for all the axis in motion?
E g. If x is 1000 and y is 500 g64 might limit things to 500 even if moving x only to make the math easier.

With no g64 linuxcnc rounds corners substantially to maintain speed. So it makes sense it would take longer with g64.

Try with a bigger g64 and see what happens. Often you can use a big g64 for roughing and a small one for the finish pass if machining. However if you are running a plasma/laser/3d printer etc obviously you can't do that
