Hi...I am not sure how to update firmware..have it downloaded but not sure how to make available to choose in pncconfig....

Thanks for any help!!

Possibly the executable path is different for root so ethtool is not found unless you use sudo

so maybe try:

sudo ethtool -c enp0s25

to see if IRQ coalescing is disabled

Hallo Aciera

Danke für deinen Tipp, aber der funktioniert leider nicht. Das habe ich auch schon so versucht. Aber wenn ich das so in die HAL eingebe, dann ist zumindest das LED am Dragon HD Screen für spindel at speed sofort nach dem Absetzen des MDI Kommandos "M3 S24000" an. Die Spindel braucht aber 5 Sekunden für den Hochlauf. Der Inputpin geht auf High, wenn die Zielfrequenz erreicht ist. Das spindle at speed ist von dem Zustand des Input Pins komplett unbeeindruckt.

LG

[Edit]
This is due to the underscore becoming hyphen-minus in components. This works:

I dont think IRQ coalescing is disabled I still get the error every time. How do I disable IRQ coalescing permanently?
   

No, just incorrect reading of the name of the driver.

I guess the correct load line should read:
loadrt hm2_rpspi config="num_encoders=0 num_pwmgens=0 num_stepgens=3 sserial_port_0=0xxxxx"

Thanks.

Runaway of an analog velocity mode drive with no input
may be because the tachometer leads are reversed.

I have just received my reconditioning drivers, 1 driver was defective in one direction of rotation.
i started reassembling the drivers and tuning the engines.
it's at this point of tuning the motors that i have a problem.

when i put enable on my drivers, my motor turns in 1 direction at high speed and when i press it, it goes in the other direction.

I remove the analog to see, and it happens again.

so i guess it's due to the settings on my drivers and the tach.

how do you set this type of driver with the front buttons?

 
 

I'm trying to link a scale output (float) to halui.feed-override.counts so I can control feed-override with an external pot. I'm using "scale" to scale the analog value.

It appears that halui.feed-override.counts needs to be a s32 type value, so I'm trying to use  conv_float_s32 to convert the scale output to s32. The addf conv_float_s32.0 servo-thread line is causing the following error:
HAL: ERROR: function 'conv_float_s32.0' not found.

If there is a better way to accomplish what I'm trying to do "I'm all ears"

excerpt from my postgui as follows:
# Feed Speed
addf scale.1 servo-thread
setp scale.1.offset 0.0
setp scale.1.gain 0.12
net feed-pot-in scale.1.in <= arduino.ain.1

loadrt conv_float_s32 count=1
addf conv_float_s32.0 servo-thread

#net feed-override halui.feed-override.counts <= scale.1.out  # type mismatch
 

Typo?

it should be hm2_rpspi

Maybe setting axis.L.jog-vel-mode to TRUE would cause in-process jogging to respond to speed changes?

Hi All,My brother and I recently purchased an old MAHO MH600T with the intention of retrofitting it using LinuxCNC, a 7i77, a 7i84, and the GmoccaPy interface. We began our project by following Mark's thread, which provided invaluable information—without it, we would have been lost. The machine originally came with an old Heidenhain 332 CNC controller, but unfortunately, the video output seems to be broken. Since this compact module also contained the EXE interfaces, we had to replace them with three EXE602 modules to read the linear scales.This is working fine (we are currently ignoring the c-axis...) and the cable cabinet still had a convenient place for its three new members. 

At this stage, we have successfully set up the endstop chain and the linear motion system (encoders and the Indramat drives for X, Y, and Z axes), using conservative values for the PID controller and homing. Our next step is to get the "accessories" working, such as flood coolant, the tool holder, and basic spindle control (including potentially allowing for manual gear changes). While the machine behaves as expected when we press the test buttons on the relay board, we are facing difficulties controlling these functions via LinuxCNC. I have a few questions about this (apologies if they seem basic, but I am new to LinuxCNC and HAL).

1. I wired the 2K2 relay for the coolant pump to output-15 of my 7i84, with field power supplied by the 24V line. The pump operates correctly when I test the relay using its test button, but attempting to activate the relay from the Mesa card causes the machine to go into an emergency stop. Even connecting the relay to my field power alone triggers a shutdown. I've double-checked the wiring (I have a connection from output 15 to the test lead MP12 and to the relay), swapped the relay with a known working one (19K1, machine on), and tested the output without anything connected (it pulls up and down correctly). I initially thought it might be an issue with using a different 24V line, but the "machine on" relay is functioning. I'm currently suspecting a short circuit, but there is no error message displayed by the controller—just the fact that the machine goes into E-Stop. Is there a hidden log or extended error message that might provide more information?

 
 
2. The spindle: For a first test, I wanted to have the spindle on/off working, which just should be the three relays 1K8, 1K9, 1K10, connected to output 12, 13, and 14 on the 7i84. but with the following hal code, nothing happens, when pressing spindle start, and the pins of the 7i84 are floating at roughly 13V. So it seems the pins are not connected in the hal. Is there something I am overlooking, do I need to use the halui pins?:3. The gearbox. The good news is that our machine is equipped with an 18-speed gearbox, similar to Mark's, but the sensing configuration is slightly different. While the outputs are the same, we only have nine inputs, which means we're missing the "Links-Mitte" switch that indicates whether the gear motor should turn left or right. Has anyone modified the gearbox component for the MH400E to accommodate this configuration, or has a working original MAHO with this arrangment and could share, how the gearshift is done there? I somehow hope, that it is just an easy modification, but my C is a bit rusty, so we will se how this goes.
 

Kind regards

Sebastian

I did:
sudo mesaflash --device 7c81 --spi --addr /dev/spidev0.0 --write 7c81_7i76x2d.bit
and
sudo mesaflash --device 7c81 --spi --addr /dev/spidev0.0 --reload
when I tried to run linuxcnc I got an error about no hm2_rspi.so found.
How do I make sure hm2_rspi is on my system?

This certainly works for me using panel buttons connecting to hal pins 'halui.axis.L.plus' and 'halui.axis.x.minus'.
Push the jog button and simultaneously change the jog speed with the potentiometer from 0..100%

[edit]
Just noticed that I also feed the potentiometer signal to 'gmoccapy.jog.jog-velocity.direct-value'. So maybe Gmoccapy has something to do with it.

Nice.
See how to edit GRUB in Debian 12, there are plenty of tutorials on the net.
Editing a single file and saving it, then doing a grub update, that is it.
