(LPT) Debian 12 Latency spikes/unexpected real time delay. Looking for solution.

Category: General LinuxCNC Questions

On the file copying front, have you had a look at scp for windows.

winscp.net/eng/download.php

Can't really comment on the windows side, I'm one of those meatheads that is totally Linux.

(LPT) Debian 12 Latency spikes/unexpected real time delay. Looking for solution.

Category: General LinuxCNC Questions

When I installed my AC servo drive for the spindle on the mill I went with the manufacturers recommendations and installed the line filters & reactor (not the cheapest item) as per the manual. Never had an issue with noise.

Tho in saying that the VFD for the Myford hasn't progressed beyond being connected directly to the AC, no filters nor reactor, non shielded leads from the VFD to the motor.

So I don't really know. And the above maybe of no practical help. Just thought I'd share my each way experience.

Devuan, RPi5 & Linuxcnc Image

Category: Installing LinuxCNC

As per title, is this something anyone would be interested, not meant as a replacement for the official image. If your new to Linuxcnc I would recommend the images on the download page.
Main reason for experimenting with this image:
Sysvinit rather than systemd, some prefer this option for personal reasons.
I really like the Devuan Project's CoC.....I know this subject can be quite polarizing for some. Yes I know it is "based" on Debian.
Just wanted to have a look at Devuan, so 2 birds with one stone sort of thing.
Out of the box no zramswap.service issue....may not mean much, but there has been a bit of discussion on this front.
Choice, whether this is good or bad or confusing.

I included network-manager & network-manager-gnome for easier network setup. There is some debate regarding the affect on latency, so there is some debate around that. Also some nice stuff such as xarchiver & thunar plugin (create & expand archives via right clicking in thunar file manager), evince (pdf reader) so for those that are curious can read the Linuxcnc docs.
As per the bookworm images menu-config is used to set locales & such and same username:password to login, cnc:cnc.

Have Fun

Yup, you can right click the hal show window and select always on top, and it will remain on top

No Keyboard jog after update 2.9.3 to 2.9.4

Category: QtPyVCP

A couple safety levels were added, make sure both of the following are added for keyboard jogging.


KEYBOARD_JOG = true
Ctrl+jog key will work.

KEYBOARD_JOG_SAFETY_OFF = true
Removes need for Ctrl key

7i76e - Spindle FWD/ENA ok, but no speed output

Category: Basic Configuration

If you run LinuxCNC, enable the spindle and set the spindle speed say 1/2 way up, then:

halcmd show all | grep spin

and post the results here, that would help debugging this.

Have the same question since a while, because of HALshow while experimenting with some settings was not possible simultaneously.
Thank you for the question Martin, and Lcvette, for the answer!

Hello, I have a T3D servo driver and a Mesa 7i97T board, how can I connect them? I don't know how to install the Mesa 7i97T board, and I would like to know how to connect it. These are the only pins available on the cable:
0V
P+
son
alm
D-
D12
D04
P-
24V
D+
but more appear in the manual.

7i76e - Spindle FWD/ENA ok, but no speed output

Category: Basic Configuration

Hello together,
another question and problem with my LCNC config.
After solving installation, homing, network, latency problems with your help, I could make the next step and check my spindle output function.
I'm using a chinese 2,2kW standard spindle with a Hitachi WJ200 VFD, parameters set with Hitachi proDrive, the FWD/Stop control is working correctly, but I cannot measure any volts at the Spindle Output of my 7i76e TB4. The electronic pot gets 10V from an external voltage source, these 10V are measureable at TB4, Pin 3.
Im using Probe Basiv V.5 under Debian 12 and LCNC 2.9.3. on a Lenovo Think Centre M92p Tiny, 8 GB i5 2900 GHz.
I set the output with MDI S6000 and can see, that spindle-out goes to 100 (rps), Spindle-enable goes on, but I can not see any voltage at Pin 3.
Do you have any idea what is going wrong here?

Wiring:
8 Dir + STP (Hitachi WJ200 D2)
7 Dir - GND
6 En + STA  (Hitachi WJ200 D1)
5 En - GND
4 nc
3 SPI + +10V external voltage
2 SPI OUTPUT  -> Analog In O
1 SPI -       -> GND, L


INI:
MAX_OUTPUT = 24000.0
OUTPUT_SCALE = 24000
OUTPUT_MIN_LIMIT =  1000
OUTPUT_MAX_LIMIT = 24000

HAL:
#    SPINDLE
#  ************
# ---digital potentionmeter output signals/setup---

setp   hm2_7i76e.0.7i76.0.0.spinout-minlim    [SPINDLE_0]OUTPUT_MIN_LIMIT

    #net spindle-brake              <=  spindle.0.brake
    #net spindle-revs               =>  spindle.0.revs
net spindle-at-speed           =>  spindle.0.at-speed
    #net spindle-vel-fb-rps         =>  spindle.0.speed-in
    #net spindle-index-enable      <=>  spindle.0.index-enable

# ---Setup spindle at speed signals---
sets spindle-at-speed true

Thank you for any help!
Hanno

EtherCAT XML Configuration help (Elmo drive)

Category: EtherCAT

Ive been wading through posts here for a few days now. managed to get a master up and running, and the slaves to appear. As far as I can tell the next step add the drive to linuxcnc is to either find or create an XML file for the drives. I scavanged some Elmo Gold - G-CEL50 drives that I would like to use and figured I'd ask if there was anyone here who already created or found one. I've searched a bit around for next steps but did not have much luck, any help would be appriciated.

Thanks in advance, 

Steve Cap

I see from other posts that with intel network card I should disable IRQ coalescing. I will try that in the morning and repeat the ping test

I like the way you think my friend, I've tried that several times already with the same result. I have a Meanwell power supply that i fine tuned with my Fluke to exactly 5V I really think i have a bad card. I have never not once been able to get any actual motion control out of this thing. Now i need to navigate the seemingly unreachable Mesa company and see if they can help me. I e-mailed them a couple of days ago with no responce. Looks like this is going to drag on into eternity.

Getting QTDragon settings values from within remap.py

Category: General LinuxCNC Questions

How can I get the X & Y values of the Tool Sensor Location from Settings tab in QTDragon_HD from with remap.pyThis code below works when getting the values from the .ini file but I would rather use the values from QTDragon’s screen.self.execute("G53 G0 X[#<_ini[TOOLSENSOR]X>] Y[#<_ini[TOOLSENSOR]Y>]")

Thank You.
