I created a program in Fusion 360 and everything looks right on screen using the linux post, also looks right on linux cnc screen loaded program, a big but, it machines rotated and flipped when machined and it is just tracing letters and numbers ! please tell me why.

Also, on your website the manual is hosted by google drive.

You can store the PDF on your website, or on GitHub, or Cloudflare Pages.

Something about Google Drive just does not inspire confidence; no clue why though.

google drive is my harddrive, its very easy to update, revise or edit the document,
I suggest to you to use it:)
github or cloudflare is somewhere far away from my computer,

langdons post=334132 userid=41217What's with the resistor reaching across the board?

This board is first release, it will solve in next version,
 

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.

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.
