Probe Basic.

Yes all axis was homed.

I jogged down the spindle to tap the touch plate. Tried pressing the button but no response.

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.
