A 7I76EU should work on any system that supports a 7I76E.

Older (Pre-7I76EU) versions of LinuxCNC will complain about
an unrecognized card, but this does not affect operation.

 

Hi guys, is there any way to get a 7I76eu card working with linuxcnc 2.8.2? I need to replace a 7I76e card on an old pc where there are a lot of scripts in python 2.7... thanks for any advice

What version of linuxcnc are you using?

1-check if the CapsLock is active
2-did you change the keyboard layout
3-mind the user name and password fields
4-do NOT enter password for ROOT if it asks, just skip to next step.

I'm not a developer, but I'd say to use the code for the stm32f4x and use some AI magic to make a DMA stepgen.

I have attempted programming a g-code to do a pecking action on the x-axis. Since this is a lathe it does not have a y axis and I keep getting an error. 
Is there a G-Code for pecking on a lathe?

Thanks in advance.

Well, it's all working again. I increased the deadband from 0.001 to 0.01. Now it's also working on the old speed settings and with 2 microsteps.

Seems like there is still one question remaining:

What would be the ideal set up for a stepper motor with 5mm pitch ball screw and 1.8deg/step paird with a DM332T which can't go below 2 microsteps. Is there a setting which is ideal for this set up where linuxcnc positioned the machine on exactly a step/microstep?

I did have a look through this a couple of days ago.

To me it seems like a very worthwhile use of time to get this up and running. I think it would be very valuable to anyone wanting to do multi axis work.

I'm unfortunately not that experienced with coding. However, this would be a huge benefit for me to get working, so I'm going to spend some more time going through it.

I tried to reduce the mircsteps from 16 to 4 and played around with speeds for homeing. I am able to home. This is now discovering the real issue.

When I manually move an axis of the machine sometime it stops. And sometimes it continues to move slowly. For example in X I see in the display that X is 0.00000 and jumps around to 0.006252 or so. I believe this has happened already and has something to do with the F error or F min or so.

7I73 is an lcd/matrix and io expender so you may need voltage shifters  for some of the pins. If your are not planing to use lcd/matrix keypad  Then I would suggest you get  7I84U, the i/o's are 5 to 28v tolerant. four input pin voltages are readable with 8 bit resolution.  Two MPG encoder inputs are provided as an option on four  field inputs

I am chasing a weird issue. I reduced the microsteps on my machine from 16 to 2. That changed the scale from 540 to 80 on x and y and 800 to 100 on z.

Now my machine is not homing anymore. I get this error: home switch inactive before backoff.

Here is what I have done so far. 
1. Changed the Microsteps from 16 to 2. And just changed the rio.ini file. 
2. Machine started homing in the right speed settings, but threw the above error.
3. I changed back to 16 microsteps and the machine is homing fine. Changed back to 2 microsteps. 
4. I tried to reducde the home search velocity, but no change. 
5. I increased the home search speed and the machine is not showing an error, but is not homing. It does it homing cycle, but then continued to go in slow speed. I believe towards home, but not sure.  

yeah the most commonly recognized home position is where the head is at the top of it Z+ travel.

Pippin88,

Unless you can figure out why activating an output via gladevcp would prevent jogging, I'm going to close this thread.

As a work around, I've configured a front panel switch in parallel with the relay controlled by gladevcp so I can toggle the crosshair laser from the front panel or the VCP. I've also added a 5v relay that triggers when the laser is activated via either the switch or the relay. When triggered the relay activates an input that is attached to the crosshair LED in the gladevcp. This configuration activates the LED regardless of which method is used to provide additional visual feedback to the operator that the LED is on.

Thanks for your interest and support for this issue.

My machine has mpg wheels to control feed and spindle, halui.feed-override.counts and halui.spindle.0.override.counts
Is there a way, to make the sliders follow the adjustement with mpg wheel?
 

You can use a HAL_IO slider and the slider position is updated when the count changes. Note a QSlider is an integer only widget.
You will need a fresh copy of Flex GUI as I just fixed that a HAL_IO QSlider didn't get updated when the value changed.
