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? 

Hello
I'm a newbie. I started DIY Ethercat board with AX58100
1. AX58100-16in-16out
2. AX58100-Step/DIR + Encoder ABZ +8in/8out GPIO

Everything works on Twincat and I can connect it to Linux lcec

I want to use it with Linux CNC as 3axis and 1 spindle
In the axis there are
-Step/Direct
-Input8
-Output8
-Encoder ABZ
And there is AX58100-16in-16out board as the main I/O of the system

But I still can't create the correct ethercat-conf.xml file. I don't understand if it needs to be used as CIA402 or not
I have attached the XML files from AXIS for both boards

Can you please suggest a generator for ethercat-conf.xml for this project

Thanks for your support

 
 

The system does have brakes which I have disabled (the joint free drops when it gets the follow error)

it doesn’t have a physical counterbalance that I can tell, maybe the gearbox has some sort of clutch?  

When idle, the motors are able to hold the joint in place even if I push on it.

I have a feeling that there’s something off  between the motors and encoders.   When it moves, it seems to be miscalculating the actual vs expected travel - but that’s just gut feeling.   It sometimes errors moving up, but not always.. it always errors moving down.

Just add a VCP button, if you need it.

link to fdarling's sample code if you don't already have it by now.

Is there any way to create a button to select two different accelerations? example
my machine has an acceleration of 1000ms2 in the ini file, I want to create a button in the axis interface that when I press it changes the acceleration to 500, so I can work with heavy parts more smoothly without having to change it manually
