Cute machine!
Since you have 6i25, Mesa 7i76 would be the preffered choice, and it has full spindle control, even with encoder feedback.
Keep in mind that you have to power the machine after LinuxCNC starts and power off before shuting the PC down, while using 6i25 in parallel port mode.
I would make the machine work as is first, then get the 7i76.

Regarding crashing, check what video codec is causing it, usually that is the reason, although when recording from a mobile phone there is no choice of cedec.

What version of LinuxCNC?
2.10 has tandem limits so it should have tandem joints also.

Depends on what system is used on Z, steppers can not do torque sensing (even TMC drives miss that a lot), servos can do that but in most cases they would require opening the drive and soldering extra wires as not all have monitoring outputs.
The easiest way, floating head, and it does not miss.

Check encoder PPR, make sure the scaling is correct, then we can move to tuning.
In the meantime, upload the config files here so we can have a look, just in case something is off.

I got a reply email from the AX58100 manufacturer saying that it is not possible to use only AX58100, need to use external MCU via SPI.

But no answer about working as IO. I want to know if not using CIA402 can still be declared as input/output. 
 

Thanks I will try that next.

Do you have any recommondation on mesa daugther card.Considre 7i76there are also D and U card but dont know what that means.

Im more used to lasers/3d printers.So I went in to this blind.

Its an entusiast build in a makerspace.With tool revolver/tool changer on top.added some photosIts name is "Phil the mill

24volt for most attachments
added a few photos

Please follow steps 44-58 in the google doc on the other thread.
I don't think you have installed the r8168-dkms driver.

Shotcut for me. it's open source and works . Mine will crash from time to time though. if interested see the link below

I would insert an M63 P.. before the move in question to set a digital output synchronized with the start of the movement. Then create a realtime component that starts to calculate the 3d distance when the digital output goes true and outputs a signal for every 10mm of travel.

I need to make an addition to a GUI I created using Python and QtDesigner.
Is it possible to control an output at the same time while a line of gcode is being processed?
For example,the machine started to move from (0,0,0) . The gcode in process (G0 X60 Y80, Z-5) is making a movement in x,y and z coordinates and the movement is 100mm.
I need to toggle one output for every 10mm progression.
How do I do that?

Hallo,
You can find the center of the hole in Manual mode.

- Jog the Maschine so that the probe stay near the middle of the hole.
- Jog X minus until probe contact
- Zero X axis (easiest way in gmocapy by clicking on the X-Letter of the DRO, you will get an Input panel)
- Jog X plus until probe contact
- go to MDI mode
- enter the DRO value of the X Axis divided by two I.e value shows 57.859 you need to enter G0 X[57.559 / 2]
- Zero X axis

- Jog Y minus until probe contact
- Zero Y axis
- Jog Y plus until probe contact
- go to MDI mode
- enter the DRO value of the Y Axis divided by two I.e value shows 67.859 you need to enter G0 Y[67.559 / 2]
- Zero Y axis

If you want, you can also write a small macro and put that on an button on MDI page.
Take as an example "go to position" from an Sim config. The DRO value is stored IMHO in a var value and can be reached from within the macro. But this is untested!

Okay then, I'll try stepconf again.

Hoe would I then teach the machine to accept a as y2? As far as I'm aware, there's no setting in stepconf for that.

Hello what are some methods to make initial height sensing work for underwater cutting. I am using a hypertherm ht2000 with a pneumatic breakaway so I would like toavoid modifying it to floating head. Is it possible to accurately use tourqe sensing to determine the top of the plate when plasma cutting?
