Okay, the information that I was looking for is actually documented but it is a different one called STEPGEN. There I was able to find what steplen, stepspace, dirhold and dirsetup corraleted to, which are t3, t4, t2 and t2 respectively. Leadshine documentation is in micro seconds, it should be translated into nano seconds, which is x1000.

This wens away and then started coming back again, and I think I have found what is causing my error, apart from me:)

In my original post I stopped the g-code at the G0 X208.659 Y25.039 line but it is the line after the is causing the problem. That is a G43 and the H value points to a valid tool but not the one I am using. It is loading the offset for whatever that tool last touched off to.
Even if it was right tool it would be whatever the last tool touch off measurement that was stored in the tool table.

Unsure why running the job again fixes it, but pretty sure that is the problem.

Sorry for screwing you around, but thatnks for the halp.

Thanks to everyone I currently have 2 linuxcnc machines running but I lack the knowledge of fine tuning stepper values. I am currently using Leadhshine M542 drivers and I attached the documentation for it. I read the stepper tuning document many times over but I couldn't find the direct values mentioned in the M542 documentation.

• Step Frequency
• Step Pulse (0) time
• Step Pulse (1) time
• Direction Setup

I think the information is at page 4 there is a chart for Connector P1 Configurations and at page 8, 10. Sequence Chart of Control Signals. 
These 4 values will be translated into;

• DIRSETUP
• DIRHOLD
• STEPLEN
• STEPSPACE

I will be happy if someone can explain, therefore I can use the same logic to apply to my other machine.

hi Rod
everything is still broken here, I read the answer Bjarne, I don't understand if there is a way to restore things, I tried without success
many thanks

You need to set up the driver manually. If there is software for the driver it is a very easy task. Automatic settings have never worked well for me.
A minimum error of 1 is too large for most machines.

Thank you!

Hello,

I am in the process of ordering the necessary components to retrofit my CNC mill. I just worked my way through the mesa selection guide and worked with the configuration tool. Now I would like your help verifying my selection so that as a beginner I don't make a costly mistake that could have been avoided.
The requirements are as follows:
3 analog servo drives with feedback from glass scales
1 Spindle vfd
3 mpg handwheels
34 digital inputs
18 digital outputs

At some point I would like to add physical buttons to the operators console, which would be realised with an 7i73 in the console.

The PC is in the operators console as well, and can only be connected to the mesa cards via ethernet.

In another post tommylight suggested I use the 7i97t, which can support my servomotors and the mpgs as well as a few inputs. Ideally i would expand this with a 7i76, however that is not available for me in europe.

Following the guide I came up with a different setup. As FPGA card I could use 7i96s and then connect 7i77 with the 25 pin connector. That leaves the smart serial connection for later use with the 7i73.
7i96s: Main FPGA board, controls spindle, 3 MPGs(6 inputs), 5 inputs, 6 outputs
7i77: controls the servo motors, takes the feedback from linear scales, 32 inputs, 16 outputs
7i73: keys and encoders on the operator control

so that should have me covered, or am I missing something?
 

I just installed mesact_2.1.5_amd64.deb over 2.1.4 but running it still shows 2.1.4-Build Date 7/16/2024 in the title bar. Any ideas? Synaptics package manager shows that v2.1.5 is installed.

Thanks

Its possible only the base configuration (7i97t_d.bin) has been
updated to include version 1 PWMgens

7I97T+7I76 with version 1 PWM firmware:

 

 

You can determine module versions with mesaflash's --readhmid option

 

LinuxCNC Version 2.9.2
Mesa 7I97T + 7I76 Firmware 7I97t_7;i76d
Mesaflash 3.5.9

When attempting to enable PWM Dithering I'm getting the resulting error:

     ./main.hal:63: parameter or pin 'hm2_7i97.0.pwmgen.00.dither' not found

I see in the HOSTMOT2 manual that "PWMGen firmware version 1 or greater" is required for dither.  Is this the problem?  How can I determine which version of the PWMGen firmware my card has on it?  Is this the likely issue?

Thanks,

Skylor

Nooo, that page says its part of Debian so nothing to do in the apt foders
Can you try
sudo apt update
sudo apt install samba

Yeah thats how I usually install it except when using the Debian 12 Bookworm PREEMPT-RT ISO found on the site here on the linuxcnc.org/downloads/ page it doesnt work and gives me the error: E: Package 'samba' has no installation candidate.

It installs just finew when using the ISO from the Debian site but when using the Debian 12 Bookworm PREEMPT-RT ISO from Linuxcnc.org its a no go
 

Talking about developers, payed ones:

Yes, bit that was constrained to a certain type of device (VFD for centrifuges for U238 to U235 enrichment), this is not.
On the other side, anything is vulnerable, it just takes a bit of time, and knowledge shortens that time a lot.

I wanted to be able to test it in qtdragon so it's PyQt5 instead
This one does work as a standalone window
