Error getting packages on fresh install on Raspberry Pi 5

Category: QtPyVCP

Is there an updated file?  I clicked on the links provided and it said the files were in owner's trash.
The problem I've been running into with installing Python3-probe-basic is that I can't seem to get the repository to be recognized.  I tried adding the repo to synaptic and also tried adding to /etc/apt/sources.list.d/linuxcnc.list.  But there are multiple repo urls and I'm not sure if I just didn't find a valid one.

Teknic Clearpath SDSK wiring to 7i96s

The outputs are SSRs so act like relay contacts/switches
The do not supply power, they only switch it.

I get it now. Thanks!

This is the current state of my understanding of how to wire a Clearpath SDSK DC servo to a Mesa 7i962 board:

File Attachment:


I have also modified the HLFB circuit, based on the graphic below, from page 51 of the Teknic Clearpath User Manual Rev. 3.23:

File Attachment:


Please correct me if I have gotten anything wrong.

The above graphic assumes the +5-24VDC is not internal to the board, so... is it? Do I need to apply +5v somewhere to drive the HLFB circuit? Keep in mind, I have to add 6x NPN NC sensors, and the above would need to be compatible with that too.

Min Max limit error on only one axis was created by mjones@welfab.ca

Min Max limit error on only one axis

Category: General LinuxCNC Questions

Hi Guys, I'm sure this is a simple solution but it is escaping me.  
I have a 4 axis lathe x1,x2,z1,z2 but in hal and ini are called x,y,z,a, I would like to change that eventually but that can wait till things work.  After alot of messing around I finally have my homing-limit switches working, reading and the machine homing proper (yay). but for my z axis, after I went into ini and set the min max for all the axis when I started Linuxcnc saying my, and I'm paraphrasing here, z axis isn't right they should be 1e99. From what I can tell that is for a rotary axis.  In the ini its states its linear, so I don't know why I am getting that error.
Any ideas what I'm doing wrong, I know its going to be some stupid that I'm not seeing or thinking of.

Python4Lazarus Undefined symbol: PyExc_ValueError

Category: Advanced Configuration

Did you get to the bottom of this?
My initial feeling is that the two apps might be using different Pythons, which may exist in different codespaces on the PC.

LinuxCNC pretty much only runs with Python3 now, is your Lazarus code running on Python3?

One possibility might be to trigger the hal_manualtoolchange using a G-code "digital output", ie M62 and M63 and to wait for the user to press OK with M66

Thank you, i checked on the machine and you are right, they have integrated flyback diodes. I will check wether they draw more than 350mA (i can't imagine they do)

Another question:
Since i have the full documentation fory old siemens 810t control i can check all sorts of servo calibration values from the original machine data. Certain 8-bit codes can be decoded using the docs. You i try using that method or would you do it from scratch as it it is a new machine?

I better don't say it out loud, but it all looks pretty straightforward to me :P

The I/O board is almost the same as the 7i77, theoretically i can connect 24V power, servo control and all IOs with original wiring and get straight into configuration mode.

Reality check incoming....

(PREVIEW, stop) is some other GUI command, in Flex you uncheck the show program button like I showed above. I have no control over what LinuxCNC does when you open a program, I can only turn off or on the preview.

Teknic Clearpath SDSK wiring to 7i96s

Category: General LinuxCNC Questions

I mean connect all drives ENA+ lines to OUT0-
All drive ENA- lines to ground, and OUT0+ to +5V

Thank you for everything so far.

I just looked at the 7i96s manual, and on page 10 I see that TB3 pin 13 is labeled "OUT0-", so I guess I was on the right track, sort of.

It's still not self-explanatory what you mean by OUT0+ to +5v, although you sort of partially explain it on page 14. Do you want me to connect my +5v power supply to TB3 pin 14? Doesn't that make it an input? Does every output (pins 13, 15, 17, 19) need its own power supply connection (pins 14, 16, 18, 20)?

You could avoid a lot of this back and forth by just publishing a typical use case wiring diagram. When I have this completely figured out, I am going to edit the top post, to accurately reflect the working system. Both for future me, and for others coming here to figure it out. That will hopefully also include all of the HAL changes, etc. I have seen other posts about Mesa boards and Clearpath SDSK, but they are sprawling conversations lacking a single definitive graphic at the top level that is accurate and well-labeled. I don't feel obligated to read the contents of the entire internet in order to hook up a servo motor.

I have heard great things about working LinuxCNC systems, but I have never heard a single positive experience from anyone setting one up.

Look out for an updated graphic. I'll be modifying the one above for the next hour or so, with my second cup of coffee.

IHSV60 integrated servo moves when removing power or disabling it

Category: CNC Machines

I guess one way is to use a normally closed relay/SSR
to power the drives disable inputs until LinuxCNC energizes the
relay with say motion.motion-enable. Its still awkward as it requires
control power be present to disable the drives.

I know this is common in step drives as it allows the enable input to be
ignored so simplifies wiring and probably results if fewer technical
support costs, but it is really counter-intuitive

I wonder if the setup software can change the enable polarity
over the RS-232 port?

IHSV60 integrated servo moves when removing power or disabling it

Category: CNC Machines

The drives gets 5V constantly when disabled. To enable them I have to remove power from the enable pin. For me this logic is counter intuitive, meaning that if a wire breaks, the drive enables(the opposite of the logic used in E-Stops).

I'm looking for a way to invert that logic, but drive wise I couldn't find anything

EDIT: the drive manual indicates the following: "SW5 dial code switch sets input edge, off means rising edge and on means falling edge."
I don't know if this is going to change things, either on the enable, or both the enable and STEP/DIR(changing from falling to rising and vice versa shouldn't change anything about step/dir, am I right?)
