6.1.0-30-rt-amd64 #1 SMP PREEMPT_RT Debian 6.1.124-1 (2025-01-12) x86_64 GNU/Linux

Version of Linuxcnc
2.9.6

Version of QtPyVCP and Probe Basic
0.0 & 2.9.6

Howdy folks,
Forgive me in advance as this project is the first time I've touched linux, linuxcnc, probe basic, or attempted a CNC conversion. I used the quickstart guide to install, and I've gone through the hal and ini files. Although, both the hal and ini files could be severely incorrect now. I believe I have the necessary config files.

Now, admittedly, I've used ChatGPT way way too much for this, so I might need to start from scratch.

So, after installing linuxcnc, the sim.axis worked great, X and X moved well and were moving roughly correct distances (I don't have my Z installed yet).

I then installed probe basic and went through pncconfig to make my custom config file that opens into probe basic. In that custom config I can't get anything to work. The E-stop button freezes the screen for a few seconds, but it never disables the E-stop.

And now when I open into sim.axis, everything works but my motors don't actually move. E-stop disables, machine turns on, and jogging shows in the graphics.

Just trying to get some motors to move and maybe make a circle with gcode. That'll be a step in the right direction. HAL & INI are attached. Also I'm running a Lenovo M710Q with a Mesa 7i96s.

Thanks in advance

 
 

 

On the 6I25/5I25 mesaflash lists DB25 pin numbers

DB25 connectors are numbered:

1    2    3    4    5    6    7    8    9    10    11    12    13
  14  15  16  17  18 19  20  21  22    23     24    25

Also you don't need to use GPIO to invert step or dir pins, there are aliased names like:

hm2_5i25.0.stepgen.00.direction.invert_output

hm2_5i25.0.stepgen.00.step.invert_output



 

I believe it's Bob if I did the flash right. I'm still not 100% on how all these talk and write to one another. I'll run the readhmid after I am done making dinner.

I'm not sure if this nomenclature starts at 0 or 1. It's physically the 8th pin starting from 1 which is how I understand DB25 to be counted by, but the config starts joints from 0 and I'm not sure how to describe the count due to that.

2.9.7, Preempt rt ISO

Stepper online, no clones.

axis

The drivers, CLXX's no daughters.

I think the problem being between the 6i25 and the drivers is probable.

I tried some weak oscilloscopes. Nothing better than AC multimeters, it just read gibberish. I really should get a good one as a work expense. Something that can ID freq bands. I could go that route if this SHOULD work.

So, to be more coherent on the control desires....

1: A new UI skinning of (probably) qtdragon, possibly vertical layout. I'll do the layouts, I'll need help turning it into a real working UI.

2: A linuxcnc build with a configuration wizard that includes ethercat and modbus, atc types, and some specific presets for lemontart (and then presets for any other machine people like - maybe presets can be just saved out from peoples manual configurations and shared).

3: Jerk limiting.at minimum on any exact top moves. Secondary is to add it to other motion. Bonus points for integrating all the fancier TP stuff from the tormach 1500.

For the physical control, I'm going to do a printed panel, with waveshare touch display, and a common low cost passively cooled dual nic mini itx board. Just so its easy and standard. "go buy these things, assemble, load linuxcnc onto it and run set up wizard"

What firmware are you using?

sudo mesaflash --device 5i25 --readhmid

Will print the pinout of the currently installed firmware

( assuming you are using the 5abob firmware, DB25 pin 7 is stepgen 2 DIR, not STEP )
 

And we're done. Coordinating to start production tonight. Eep! (goes faster when someone else does all the work... and pays for it. )

What version of LinuxCNC are you using?

Did you install from the ISO?

Did you buy those drivers from stepperonline? (there are clones of the clones)

What GUI are you using (I assume AXIS)?

What does the 6i25 connect to?

Perhaps the problem is whatever is between the 6i25 and the drivers.

The pulse pin carries high frequancy pulses, don't trust a multimeter to reliably measure it, especially when it's set to DC.

Try setting your multimeter to AC, or use an LED+current-limiting resistor to view the pulses.

I've been working on a large format gantry cnc for a few months now and while I have plenty of mechanical design experience and a decent bit of controls, LinuxCNC and this style of hardware is well outside of my (current) comfort zone. I've got my HAL/ini files loading into LinuxCNC without error, and am starting to get the hang of syntax and method for this kind of machine control, but I've got some pretty glaring rookie issues left to sort. 

I can power up the mesa board and actuate my steppers with mechanical switches on the 5v and 0v outputs, so my machine wiring is functional and my driver is not fried or otherwise inoperable. I am using 5v on PU+ for power input and then grounding PU- on my z axis stepgen on pin 7, starting the pin count from 0. I have inverted the pin with setp   hm2_5i25.0.gpio.007.invert_output true in my hal and the pin reads 5V when idle so I think I have everything right up to that point. However, nothing moves when homing or jogging a joint, and when I let the home run I see no activity with a multimeter on the pin. I feel like I am doing something dumb and unless I can find a solution I'll go get some daughter cards for the 6i25. For several reasons none of the standard offering quite fit my needs but I can make some combination work. 

Any advice? I've called into Mesa twice and have been able to make a lot of headway from the info gained there to even get to this point but this is where I am starting to stumble. I feel like I am missing something on timing or tuning obvious in retrospect. Files attached.

My Home Position is at the top of the Unit.

yes, I am using the Tool setter Page for the spindle Zero. However the Manual measurement was only off by 0,39mm (202 vs. 202,39mm).

I was using the Automatic Tool changing but had some issues (putting tools back sometimes stopped before the pocket and I had to restart linuxcnc, them the Tool was duplicated in the rack). For now I am switching by Hand.

linuxcnc@linuxcnc:~$ ethercat -p 0 sdos upload 0x1600 0
'sdos' takes no arguments!

ethercat sdos [OPTIONS]

List SDO dictionaries.

SDO dictionary information is displayed in two layers,
which are indented accordingly:

1) SDOs - Hexadecimal SDO index and the name. Example:

SDO 0x1018, "Identity object"

2) SDO entries - SDO index and SDO entry subindex (both
hexadecimal) followed by the access rights (see
below), the data type, the length in bit, and the
description. Example:

0x1018:01, rwrwrw, uint32, 32 bit, "Vendor id"

The access rights are specified for the AL states PREOP,
SAFEOP and OP. An 'r' means, that the entry is readable
in the corresponding state, an 'w' means writable,
respectively. If a right is not granted, a dash '-' is
shown.

If the --quiet option is given, only the SDOs are output.

Command-specific options:
--alias -a <alias>
--position -p <pos> Slave selection. See the help of
the 'slaves' command.
--quiet -q Only output SDOs (without the
SDO entries).

Numerical values can be specified either with decimal (no
prefix), octal (prefix '0') or hexadecimal (prefix '0x') base.

"Invalid output configuration" means SM2 isn't configured correct. You ethercat-conf.xml now looks fine.
It can be that you may need to configure sm2 yourself using initcmds.
Let's investigate a bit first. Enable ethercat debug with "ethercat debug 1", try to start linuxcnc
and show the contents of syslog from that start attempt. There should now be more output in there.

Secondly, investigate what's in SM2.
Show the output of... as many as the output of the first command says. It should say 4 I guess.
This output should match what you have in ethercat-conf.xml Index subIndx and length in 2+1+1 bytes,
like 0x60400010 for index 1. If one find that this mapping is wrong, one can download the wanted mapping.
And -p 0, the zero is the slave number of your servo.
