Set spindle speed was created by nigelh

Set spindle speed

Category: HAL

I've just spent an unfruitful few hours searching through the HAL stuff to write a simple spindle speed set routine.
HALUI allows me to increment and decrement it in 100s but nowhere can I put in 350rpm and get it.
Is it so obvious that I've missed it?
Can I make the HALUI steps smaller, 10 or even 1, and 'buzz' it up and down?
There is an 'Increment=' value for a spindle0 in the INI but changing that from 100 didn't help.
Can I fake up an S command?
I'm sure you smart guys have done it and I must confess it is to use the mill for a pretty deviant job not pure metal cutting but...

Thanks for the replies, finally disabling #SERR in the BIOS settings helped.
I uploaded the bin file 5i25t_7i77x2d.bin to the card
Now I am dealing with creating a configuration using PNCconf. I don't have a choice of 5i25t card here. Should I create the files for the 5i25 card and then overwrite the .hal file of the 5i25 to the 5i25t?

Glad you got it going.

If you wanted to you could post the .ts file when you have finished your translations and we could include it in master branch.

Category: General LinuxCNC Questions

I have actually found 4 companies that make software, 1 of them is relatively affordable. The issue again becomes generating tools path. I am curious about the Freecad work offset bench however. does freecad support 4th axis or C axis work ? I was considering adding a indicator with a radius foot that could act as a encoder onto a set of centers I have laying around with a encoder to grab the pertinent data. Very open to ideas on all of this BTW. the air cutting issue isn\t that big of a deal. If I can figure out how to generate the roughing profiles on the C axis, I can add a spindle to my lathe, rough turn the camshaft and then rough in the cam lobes. Stand it up and drill the ends or do it as a C-axis drilling open for the locating pin or bolt up.

I am very open to suggestions on all of this BTW

Xilinx Setup to edit config for 7i92T

Category: Driver Boards

Hello, I am trying to set up my 7i92T for my existing controller (a Mechapro Slider SFX), and am struggling with the very first step: I have tried the two computers in the house (Windows 11) and both refuse to install the Xilinx Software ("Virtualization needs to be enabled"). I have made sure the BIOS virtualization is on, and have also tried some youtube trick to install Oracle Virtualbox already - but no success so far. 

Is there any further trick I miss?

Alternatively, I thought I could use Raspi I want to run LinuxCNC on, but I have no idea if I can install the 4 .xz packages: do I need to unzip them all four in the same folder? How do I trigger install on Linux?

Or, if anybody has the software already installed for a 7i92T, would you be willing to program it with the below ports?

Thank you!!

These are just my opinions but, you dont need isolation and you would not design to read the raw arc voltage. Most decent plasma's will give you a divided arc voltage output, most common divider ration being 50. So an arc voltage of 100, would read as 100V/50=2V. You probably only need some filtering, input buffer and over voltage protection.

I took a quick look at the AX schematic, seems its only used as a gateway and none of the "special" features are used. This begs the question, why the AX instead of the LAN9252? To me the AX seems hard to get, are there benefits to use the AX as a gateway?

What are your plans for the plasma build? Do you need the MCU to do the step/dir? Or could you just get an ethercat drive and let that handle the motion side? Then you could probably use a much simpler (cheaper and smaller) MCU for IO, Analog input, maybe an encoder for pendant etc.

Advice on Protectli V1210/V1211 for LinuxCNC

Hey thanks, they are pretty cheap for what it is, but the main issue is I am in Mauritius and there's not a lot of good tech that's affordable here. Importing a Tower PC will set me back about 400 USD (excluding the PC) which aint great to say the least.

My main reason with going with Protectli was the Intel® I226-V over a generic Realtek controller.

If I look at getting something like an Nuc with an I3 or I5 would that be a better option?

Flashing fails then too:

xx@xxxxxx:~# pyocd flash /home/bf/Downloads/remora-rt1052-3.1.3.bin –-target mimxrt1050_quadspi
0000497 W Generic 'cortex_m' target type is selected by default; is this intentional? You will be able to debug most devices, but not program flash. To set the target type use the '--target' argument or 'target_override' option. Use 'pyocd list --targets' to see available targets types. [board]
0000674 I Loading /home/bf/Downloads/remora-rt1052-3.1.3.bin [load_cmd]
0000690 C No boot memory is defined for this device [__main__]


 
The pyocd warning is hinting that the command line is not correct and it's defaulting the generic target type that cannot flash memory.

pyOCD/docs/target_support.md at main · pyocd/pyOCD

Is there a typo in the command line arguments?




 


I used the "--target" option, like show in the help output, but i found the variable "target" in "board.py" was allsways "None". So i did the quick & very dirty fix to change default to my board:

# As a last resort, default the target to 'cortex_m'.
if target is None:
target = 'cortex_m'

to

# As a last resort, default the target to 'cortex_m'.
if target is None:
target = 'mimxrt1050_quadspi'

Finaly it flashed the board and i got it connected to linuxcnc :D

Get a HP Z420 or Z430 or Z440, they are proven reliable, but they are huge and heavy.
But the are cheaper as they can be found only used.
Also, personally i avoid anything Nxxxx from Intel, they are way under powered for anything useful, but they will run the machine perfectly fine.

Entirely possible.
There is an STM32F407VGT6 but you can switch it for your favorite MCU if needed.
Now, I am not an electronics engineer even if I do this kind of things. With that said I imagine one would need some electric isolation before the arc voltage reaches the MCU pins. One "just" needs a circuit to read the arch voltage that the MCU can read.

It looks like bad instructions on our part...

Try renaming qtplasmac_sk.qm in linuxcnc-dev/share/qtvcp/screens/qtplasmac_4x3/languages/ to qtplasmac_4x3_sk.qm

If that works for you then we will edit the documentation.
 

It is working now! Thank you for your support.

dynamic speed of spindle related to speed of x,y,xy axis speed via pwm

Category: Advanced Configuration

All joint velocities are available in hal, so if the PWM needs to track any function
of these velocities, it's possible, but you need to know the function.

Do you know the actual desired PWM  value vs joint velocity function?

Looks great!
Shame it seems that it does not have an analog input, with one of those you could of done the arc voltage reading directly without the need for a mesa pcb in between.

Well actually you seem to have a microcontroller on there as well that most likely has an ADC, why not use one of those? I did not check the schematic but will take a peek at somepoint.
