Who's the lucky winner?

I've just implemented this for myself.

I already have autoprobe routines that set g54 parameters for X, Y, and Z. I augmented my autoprobe functions to log the x and y values of every completed probe, along with the g54 offsets in effect at the time.

When I have a rotated part, I touch it twice, along a surface that's parallel to its twisted X axis. That gives me two new log entries. I have a script that reads those entries, and calculates d = atan ( (y2 - y1) / (x2 - x1) ), after correcting the x and y values with the offset information.

The script prints the result in degrees. In fact, the script simply prints the necessary g-code: "G10 L2 P0 R $angle", which I then pasted into the MDI window.

And it's true, I think. For example we really could so with a section on toolchangers. 

And Ethercat now it can be installed without breaching licenses
And how to optimise later distributions

Hi Giovanni !

Step #1     I misread that as python3-lxml being already installed with the install of Linuxcnc.      Wrong of course and caused problems

Step#3     I didn't know where to expand the zip file.      Later I seen it didn't matter moved to the gladevcp folder

Step #5   "sudo ln "   I misread that as a upper case I at first.    

Step #8   I misread   {XID}  as (XID)  which also caused problems

Misc:    aux_gladevcp  should be changed to gladevcp as already mentioned

Much of the problems were due to me printing out the instructions and the pdf being in a quite small font which lead to me misreading some things.   A larger font would help here.

Thanks again for all your work !!

Hi all,

I've changed my setup to use an ethernet-based Mesa board rather than a PCI slot one. As a result, I have the old 5I25 Superport board which I have no use for. $10 for postage and its yours. Send me an email if you're interested.

So far I have evaded shorts!

I am way ahead of you, this is also my channel
www.youtube.com/shorts/TkP5_BbfQ2g

If disconnecting motor from drive while powered on:
-TB6560 will die
-TB6600 will die
-TB6600 that is not TB6600 will most probably survive
The last ones use TB67S109 chip inside despite being named TB6600, it is much better but can do a bit lower current.
I have over 20 of the TB67S109 in daily use, the only issue i had with them is the DIP switches on 4 of those would switch at random from vibrations, so i soldered them.

Well done.

So let's do a quick recap to facilitate other users.
The procedure is correct except for the error in step 9, where is written "/usr/share/linuxcnc/aux_gladevcp", instead of "/usr/share/linuxcnc/gladevcp/".
Is that right?

Hmm I see the level shifter for the UART pins on the PRO is not present on the regular octopus v1.1(where i tested more stuff). I am having issues with another board that has a level shifter on the UART, so I will ask around if its working and test out this week and will report back

Wait. YouTube is now forcing people to do shorts?
Granted it has been a while since I posted a video on YouTube.
But if they want to push that it will be a bunch of 15 second
videos of paint drying.

However, I don't understand why G-code "96: G1 X345 Y100 Z0 F600", runs properly with F600, but when I use G-code "97: G1 X0 Y0 Z0 F600", it fails to run.

It likely depends on the maximum velocity reached, (which is acceleration and GCODE dependent)
at some point the stepgen component cannot generate steps fast enough at the current base
thread period so falls behind, causing  a following error.

 

Step motors rapidly lose torque with RPM. It is possible that at F600 you are operating on the ragged edge of what your steppers are capable of. That combined with differing friction levels for different directions or positions on you machine due to binding forces, making the machine more prone to loosing steps in one direction vs the other. Stepper motors can be queer and finicky things, and when set up without suitable safety margins, will give troublesome results.

STV is Zero Speed Command and RS is General Lock. Both signals are necessary for the servos.
But I also just see, my question was false. I want to switch signal 19 over the Mesa and ENA. With the old Sinumerik signal 10 (on both amplifiers) is switched with a safety relay and signal 19 (as far as I can see) is switched separately. The 15V is auxiliary voltage from the amplifier. I've already measured this. Therefore I think I can connect 19 to ENAx+ and 14 to ENAx-.

Hi frayja2002. I have the same problem. How did you fix the error?
