You would not normally see much of a change in STEP
pin outputs as the STEP pulses are short and do not change
the average voltage ( what a voltmeter reads ) very much.

You should see a change in the voltage on the DIR
pins when jogging in different directions.
 
It this possibly an issue with the motor drive enables?

ColorCNC Colorlight 5A-75E/5A-75B as FPGA controller board

Category: Driver Boards

Hello,
Recently I bought a 5A-75E v8.2 board, but I can't get the JTAG programming to work.
I have used the configuration file for v6.0 to build the firmware.

openFPGALoader detects the FPGA correctly, but when I attempt to flash it, it throws the following error.
linuxcnc@linuxcnc:~$ sudo /opt/oss-cad-suite/bin/openFPGALoader --cable dirtyJtag --detect
empty

I have checked my connections multiple times, they are correct. What is the issue here? Is it maybe because of dirtyJtag?

let me correct what i seen on the Step pins. I seen a very small drop from 5.08V to 5.06. Seems like something was holding it back.

Thanks.  I've made those corrections. I've made some progress today.  When i remove my physical estop button i can now hear the Z-axis brake release but still no motor movement on any axis. I took the step of putting a volt meter across the Dir and Step pins on the Mesa board.  I initially see 5V on all pins. Then i ran the MDI command 
G91 G0 X0.1.  I see values changing in Halmeter for pid.x.command, pid.x.output, stepgen.01.velocity-cmd and a voltage drop on the Dir Pins.  But no voltage drop on the Step pins.  This is the case for all axis.I feel like I'm close to getting this to work again.  My wiring has not been changed since it was last fully operational on all 3 servos.  I can't get them to move in the DMM software either.I'm attaching my Hal and Ini files.  For some reason it's not letting me load the Text files.  Any help is appreciated.Thanks Therman Simmons Fort Mill, SC

Rotary Encoder to adjust Jog-Speed?

Category: Advanced Configuration

Hi

I build parallel a pendant with a arduino mega.

everything is up.. i can select axis xyz ,select the scale (0.001 0.001 0.01 0.1 1).
I can adjust spindle feed snd rapid overrides.

now is my wish to adjust the speed when i jog.
i done this manual with mouse on desktop..

but i cant find the right hal pin :(

does someone have a idea ?

thanks!

Category: General LinuxCNC Questions

When you say the latest, do you mean a newer version than the 2.9.4? I just downloaded it a week ago, do you have a suggestion where to get a newer version? Thanks for your help.

Thanks for your help I was able to find the tandem axis for Y. I am still not sure how I will get both joints to home at the same time?

Limit 3 asymmetric acceleration and deceleration ?

Category: General LinuxCNC Questions

If you know when you are accelerating or decelerating
you could use mux2 to select different accel bounds for limit3.

I also see that there is a spindle component which supports
different accell and decell values. It looks pretty fancy
but suspect you can ignore most features if you don't need
them.

man spindle

Thanks for elaborating, a lot of those that visit very rarely document their experience. This is very useful and many thanks for your time .

We need to purge raspi-firmware packages in LinuxCNC ISO (AMD64 version)

Category: Installing LinuxCNC

The issue is the installer itself, the image uses the standard Debian installer, which for some reason installs the RPi stuff. So it's not as simple as removing the package, this has been an on going issue for the last couple of releases.
I thought I should explain a little more regarding the AI thing. At a certain time of day the forum gets bombarded by users creating spam accounts and a lot of the time it is AI generated, so anything that appears that way I become somewhat suspicious of. And also being of "arrogant English heritage" I assume everyone speaks English, tho being from Australia what we speak is far removed from the Queen's English. So I offer my apologies for my reaction to your opening post.
Regards
Rob

Actually after hearing about some of Debian's recent "woke actions" and now wanting funding from the above mentioned AI techbros I wondering if an alternate distro would be better. I know they claim it's "just to help Devs" one done wonder.
Another apology for going off topic.

Raspberry CM5 compatibilty

Category: Computers and Hardware

There is a Linuxcnc image for the RPi. There is nothing special about the image, it is just Debian Bookworm with the Linuxcnc packages installed and a realtime kernel built from the Raspberry Pi official GitHub sources with the RT-Preempt enabled, no non RPi patches are added.
I can confirm booting from SD card, USB and Nvme all work.
For touchscreen I would be more inclined to use one with a USB interface that enumerates as HID, it is far easier to setup and basically "just works". This has been confirmed with a generic touchscreen bought from AliExpress, 10.1" in this case.
For a small form factor, x86/64 is the best bang for buck, I would suggest looking into the Odroid H series, I have been using an Odroid H3 since its release and it has not let me down.
Even a 3rd gen I5 is a better solution than the RPi 4 or 5. The only advantage is the small form factor and being able to connect to a Mesa SPI board. Compared to an ex corporate PC it is quite an expensive option.
The above opinion comes from use of the RPi-400, RPi5 with an Nvme drive and use of an Lenovo ThinkCentre with an i5 I found by the side of the road that someone was throwing away.

Hallo @tommylight
selbst auf die gefahr hin dich zu nerven
was sagst du zu der kombi

7i92TH
7i76U da ran eine 
7i83 für die Servos 
das wären
5 x Takt Richtung für Servos
1 x Encoder
1 x 0-10V für Poti
32 Ein und 16 Ausgänge
und ein Rs422 - Rs485 für eine 7i83
für 6 -10 bis +10V servos bzw 0-10V servos
mit 6 x Encoder

Das wäre Flexibel durch 3 Karten vom Budget her  nur 10€ Teurer als eine 7i76EU + 7i83
Ein Firmware habe ich auch gesehen 7i92t_7i76x1pd.bin
Da die 7i83 Ja dann wie du sagtest über den Smart Serial gesteuert wird sollte das eigentlich funktionieren:)

Danke für deine hilfe und schöne grüße aus österreicht
