Update: not working after installing the linuxcnc_2.9.2-amd64.hybrid iso
No movement of axis, but i have tried it only with stepconf and the correct partport. (i hear the relay switch so its the correct parport adres)
Latency very high, about 50000 compared to 6000 with the wheezy version.
Not sure what i can try to fix it if even possible.
As i wrote already, i wouldnt care about wheezy, its just that working with onedrive was really nice, instead of using the usb stick. I would even be happy with onedrive through webbrowser, but it also doesnt work because firefox is not anymore supported.

One more thing: The system with Debian 12 seems to be somehow low, also browser is extremly slow

Save, do an update, see if it throws any error.
Why 2.9.2?
There is 2.9.3 now.

The 7i76E has been phased out. The 7i76EU is the replacement . Yes it is currently out of stock. However, I am sure
they will be back in stock soon. The first batches of them were available back in October and they seem to have
sold out quickly. Just keep checking the Mesa store.

Update: installed wheezy iso on a 60 GB SSD with Phenom X6 1055t cpu (only one RAM block used of 8gb pair, because the other one of the pair seem to be broken) and updated linuxcnc from 2.7 to 2.8.4 as it was originally with the original config - just changed to the correct partport addresses
Everything seem to work perfectly, but i havent started a program yet, just jogged.
I had to insert a old vga because that motherboard has no internal vga, and when i do glxgears it shows FPS between 4000.00 and 2500, so extremly high and then the latency jumps from about 5000-6000 to about 30.000, but only if glxgears is running.
GRUB: Isolcpus=5 acpi_irq_nobalance noirqbalance
Due to the fact that i want to use onedrive and not running around with a USB stick, i will install again the Linux 2.9.2 installer iso with Debian 12 and hope it will work now, if not then i have no other option but to use Wheezy for now.

Hello!
I just bought a THCAD2 board.
As the manual says i have to connect a 2.9M resistor in series between INPUT+ and thorch. That's clear.
I have a parkside ppsk 40 a1 plasma cutter.

My question is where do I have to connect the Analog IN terminals, is it OK to connect to the cutter's output(torch and clamp terminals) or I have to search on the PCB for the rectifiers and solder wire after them?
I'm asking that becouse the cutter have HF ignition and i don't know does the board survive 25kV ignition voltage(I read that value somewhere on the forum).
Thank you!
 

i have one 7i76e in my stock, but will the 7i76e come back again? if so i can give my card to a friend. but i'll be able to buy another later to have one as a spare again

As G38.n returns results in current coordinate system, how to get absolute G53 values.

This calculates G53 distance to toolseter. Can be used to touch off spindle or tool
#<h_ts> = trigger point of toolseter, distance to table

Touch off spindle on toolsetter, get G53 distance spindle to table surface:
This shouln't change much, if there is a good repetition with homing Z. So this 2 results can be set as ini parameter, or placed in the probing routine.


Touch off Tool, cancel toollength G49
Touch off workpiece 0, apply G43

Hi all,

i have a similar question, as above. I want to connect a THCAD to my 7i92.
On the 7i92 i run 2 breakoutboards (see below) however i can't figure out what pins  i need to connect the thcad to.
How can i find where the encoder pins are connected to?

Thanks!

the stepgen from rio also has a duty cycle of 50%,
try measuring the signal at the FPGA pin

I just installed a new 2.9,2 version. Because my internet wasn't working while I installed it. I needed to change a repository from cdrom to  deb.debian.org/debian/. Now my List looks like this. Is it correct?

 

Thank you for your help. Yesterday the router was working for three hours without any problem.

I am getting ready to embark on converting a very nice jones and shiply grinder that I recently aquired for a steal $400 USD, to linux cnc. Now the place where I could use some help from the gurus off mathmatics here. 

I want to be able to use it to grind camshafts, and crankshafts, but I think eccentric turning hal components can probably be tweaked for crankshafts. I am curious how I would 

1. generate g code for the camshaft but I suppose I could use a 2d tool paths with a end mill to generate tool tip positions, around the Z axis with x & y coordinates, the only issue is the grinder will only have z and X like a lathe. 

2. design considerations during the retrofit fit. I am thinking a servo for the z axis to control position along z in a rotary C axis fashion for grinding camshafts as indexing will be important. 

I have 3 good yaskawa AC servos packs and servos out of a hurco I tore down for parts, balls screws and mechanical tidbits for days, the hardpart is trying to figure out how to grind the camshaft lobes.  

open to suggestions if anyone has done anything similar before. 

I finally am able to get back after this, what a yr so far.

Unfortunately I guess the short answer is no, there is not an easy way to see what pins the widgets create. I should try to add it to the docs I guess.

Qtdragon use the widget pins but also makes quite a few of it's own pins in the handler file.

A increments HAL pin would be a good pin to add to qtdragon.

After more searching about Output_Scale, I have set it to 10 since it is a +-10v system. I also changed my ANALOG_MIN_LIMIT to be OUTPUT_MIN_LIMIT = -10 & same for max limit now it is OUTPUT_MAX_LIMIT = 10.

I will give these changes a shot in the morning.

Thanks.
