i just went out and checked the hand torch that came with the machine and the electrode is spring loaded just like the new straight torch. so i think it is a blow back set up. they don't sell this one anymore and the new ones i think are all HF units. the new ones are not set up with the cnc options built in the units and are much cheaper than this unit. i seen a big price difference. i paid something like $550 for my unit.

Well i figured this out, pretty strange but it turns out that there is a watchdog messege on dmseg that occures exactly every 1 minute and i had dmesg ouput on the serial port. Well apearantly this superio chip stalls when the serial port is used as anytime anything is written to that serial port there is a latency spike. Simply removeing the serial port console= line from the kernels cmdline fixed the issue.

So it would seam that on this machine writeing to the serial port blocks the parallel port for a bit, thats not too bad i can just use netconsole to monitor the system

Have read lathe user html. Pb has Standard mode and Master tool mode. I have manual tool change and want help with which mode to use and in what order and which touch buttons to use.  With the buttons SET MT X and SET MT Z my master tool (#1) sets the coordinates X and Z in the tool table to X0 and Z0, which is ok. How do I then get the length difference between tool #1 and tool 2 and tool n

Chances are this has a HF/HV start, not blow back.
But they are manageable for sure.

In Visual Code/PlatformIO in the upper right corner click on serial monitor, on the bootom part type help, that will show all the available commands, set the wifi mode, SSID and password, connect to that wifi.

i thought the air was what worked the torch with a blow back start? i really don't know too much about how the magic works. i just knew high frequency starts are bad from what i learned before. i thought the air flow pushed the contact point so the torch fires with a blow back start torch?

Ralph, you are a star, thank you. I'll try these a little later.

Could you give me a step by step? I don't really understand what I should do

the dkms drivers require linux-headers for your kernel version. I don't think its installed.
The dkms system compiles the driver for kernels if they are changed or upgraded and the headers are required

Hello,

is the any way to change the network card driver from default generic to my hardware native e1000e when I install ethercat stuff from responsitories please? 

thanks regards

I think only the generic driver is supported in the deb install. If you build Ethercat master from sources I think you can build the Intel driver which will give better performance. Check the docs which outlines the build process. Its pretty easy.
etherlab.org/en_GB/ethercat

Should do just fine.
Beware those do not have air pressure sensor so they do start with no air, and that will ruin the torch isolation in a jiffy.
Ask me how i know that?
My dad pulled the air hose on the big compressor so i wasted a brand new torch. It still works but fails to start often.

Also, don't forget spikes on piercing will be much higher than cutting. Even at 40 amps, it is enough to exceed 300 volts when cut volts is around 120 volts. Not sure how much higher because that was the max voltage my thcad was calibrated to. Also when crossing a void, when a slug drops when cutting a hole, running off a sheet when severing all cause huge peaks. A thcad used for ohmic sensing Is exposed to the full torch voltageeven if calibrated fro 24volt full scale.

A1 goes to AOUT (or spindle out) on Mesa.
0V common goes to spindle-.

Yes, that is the easiest (and probably the best) solution.
Edit:
Make configs for each tube diameter and set the scaling so they do a full rotation for each diameter.

I thought an MPG can also be used, with "normal inputs".

Similar to spindles: Some refer to the continuous power output for production and some state the "spindle goes up in flames" power.

Motor torque can be stall torque, holding torque or continuous torque at a certain rpm.
