Good catch. I just saw the 0 on the encoder port and assumed it was the same issue. I don't know about the translations either...I tried to take a quick look at the source but it immediately became clear I don't have enough understanding of it for it to be quick. Hopefully snowgoer540 can provide some guidance.

Hey, jochen91,

I received the ICs and had the boards you generously provided me with produced. However, I am facing some issues and I thought to ask you for advice.

I'm pretty certain the encoders are wired correctly, both to the board and to the 7i97t. However, I am getting virtually no response or indication the linear encoders (or the rotary ones) are even alive or powered on at all. Measuring pins on both ends of the board with an oscilloscope shows me nothing when I move the axis by hand - just a static ≈3V.

Reading the documentation a bit, it seems these scales need 5V on both pins 1 and 9 weirdly. I don't think your board design accounts for that, unless I am misunderstanding something with the jumpers? Either way, I soldered 1 and 9 together to try to get around this, yet there was still nothing to show for it.

Do you have any idea what I may be doing wrong? Honestly, I'm out of ideas at this point.

I finally found the "Signal/Slot Editor" in Qt, and the callback is now working.

Is : halcmd show pin div2.OilPump.in the correct way to write to a pin?

So did the tuning and was able to to use the THC correctly.
Still working on the tuning though.
Would it be wise to start using the last version of linuxcnc with qtplasmac?

Did that solve it for you?

Can you post some screenshots to show the difference?

just create a project in the TC3 ... setup all stuff as DC, SDOs PDOs, task cycle, names of everything ... everything will be written in the .xml of master export ... there it will be right stuff and there will be probably nothing to customize ... 

download the tool ... launch them .. write "complete" or "c" .. then drag and drop .xml export and everything what is needed to have in the .xml file will be created in the new ethercat-conf.xml automaticly .. then just connect everything in the .hal file

AX5xxx is SoE .. you will have to create custom hal driver for them probably... I do not have experiences with them at all

I do not know what which "ax5106.xml/ax5203.xml" you mean..

motor you need to tune in the beckhoff drive manager which is part of the TC3 ... it motor is in the catalogue, no extra tunnig is necessary

 

Did you set any callback in designer or in the handler?

Glad I'm not the only one loosing 100 IQ points when setting up homing......your description is perfect lol.


If your homing switch is by the operator
Set y max to zero
Set y min to -145
Leave default homing.
Set your 0,0 in g54 after startup.

The above sets 0,0 to the upper left. Getting it to the lower left isn't possible without flipping an axis (right hand rule problems).....hence the g54 zero after boot up.


If your homing switch is away from the operator....this one gets rough.
Same idea as above
Y max is now 145
Ymin is zero
All homing is inverted. (Direction, latch, etc)
Then set the y offset to -145 and it should home then drive back to the operator

This is from memory so it might be wrong....but that's the general idea. I make sure my axis is moving in the correct direction, if it's not I flip it electrically, not in software, to make this easier.

While attempting to tune some servo motors, I see pcw often recommends setting the ouput_scale in machine units per second at 10v.
I like this idea, but am having trouble implementing it on my retrofit.
Machine units are inch.
These are old servos being controlled by a mesa 7i97t using analog 10v.
I can't find any info on the motors, but they say 3,000 rpm on top.
Can I assume that 10v will spin the motor at 3,000 rpm?

Regardless, I am struggling with the gear reduction math.
The motors have a 16 tooth pulley going to a 60 tooth pulley.
the 60 tooth pulley spins a 25 tooth gear that has a dp 20 pa 20.
I come out with 1 rev = 1.047".
(3000x1.047..)/60=52.35..ips.

Would this mean i set output_scale to 52.35 in the ini file?
Should max_output be 0?
Can I set ff1 to 1?(This seems like the best reason to scale volts in this way)
And just tune p for vibration?
Or should i just stick with jt and tommy's tuning tutorials?

Thanks in advance.

 

I am building out POC with Teknic ClearPath EtherCat servos and so far the Cia402 driver is working great.. I have a question around PID tuning.

I ran around in circles trying to get the right P, I, D, FF, FF1, FF2, etc settings and couldn't get the servo anywhere near its limits before it would fail out with a joint follow error.  

I got rid of all the PID settings and now it won't fail on following but it runs a f-error of about 5.8 when I do some long mock moves (the 5.8 on the scope is a nice trapazoid shape with a ramp up, flat top and a ramp down.. )

So folks with servos that have their own internal control-loop, how do you configure your PID or tune so that when you have 3 of these guys going their combined f-errors don't cause you to make wonky parts? 

Thanks in advance..  Since this is mostly a theory question I'm not posting configs, but happy to if folks ask. 

I don't think there is a pin 0 issue as this is a 7I96s and the encoder is on pins
27,28,29

Language may be the issue, I don't know enough about locales and translations
but do all strings in the source get translated? (en_US):

                    if "Arc Voltage" in pinchanged:
                        self.d._arcvpin = pin
                    elif self.d._arcvpin == pin:
                        self.d._arcvpin = None
                    if self.d._arcvpin and self.d.frontend == _PD._QTPLASMAC:
                        self.p.page_set_state('thcad', True)
                    else:

 

Hi, I had the same issue and there was a problem with pncconf displaying the THCAD page if the pin number was 0.  I made a pull request that has been merged a couple of days ago into 2.10 master.  You could either use an input that doesn't have a pin number of 0 or upgrade to the 2.10 master.

Hope this helps.

Hi all,
Finally got around to LinuxCNC'ing my cheap bench top mini mill, making the jump from Arduino/GRBL (Ughh) to a Mesa7196S.
Problem is my Y axis is making me feel like my IQ has plummeted..

X and Z, perfect (have opto sensors at Z+ and X- (X is mounted to the left of Y saddle as viewed from front - aiming to have bottom left corner as my 0,0).

Unfortunately I appear to lack the logic to get the Y limit configured so that it can be a combined home/limit at +145mm without mirroring the Y axis!
For clarity: I want to home the machine by moving the bed fully to the right for the X axis (working) and fully towards the idiot Operator (tool max +Y), but everything I have tried either inverts the Y or results in soft limit exceeded.

My ini and hal are attached, any help will be very much appreciated!

Cheers,
Rog
