"error finishing read" with Mesa 7i92T on fresh install

Category: Driver Boards

I'm experiencing the following on a fresh install of LinuxCNC from the iso (2.9.3):
hm2/hm2_7i92.0: error finishing read!
iter=15426

this happens intermittently, but typically within a few seconds of jogging the machine around after enabling it. No motors are hooked up nor anything attached to the 7i92T other than +5V power. If I enable the machine but don't move any axes it will eventually happen after some number of minutes. I'm using a generic mini PC and have tried two identical PCs with a fresh LinuxCNC install and have the same problem on each. I've also switched ethernet cords with the same result.

I've read through this thread forum.linuxcnc.org/27-driver-boards/4691...error-finishing-read and nothing really conclusive came out of it. I do also get a real time error on LinuxCNC startup or shortly after, but doing latency tests in pncconf shows fairly good numbers. I don't have the specifics in front of me but I can get them.

 I have not tried switching the +5V supply but that is my next step.

Any thoughts on how I can further diagnose this?

Thanks!

Have the same issue converting my config files from 2.8 to a 2.9 install.
I was guessing it might be from differences in the tool change files? But I can't really check about it -.-

If doing the same thing now, I think that I would bas it around external_offsets, not kinematics.

Taking a look inside external_offsets, i too think that i could be a better solution, but i'm now wandering if i can somehow program an external_offsets matrix that corresponds to the way's warpage like the correction .STL of ProbeKins

That is a bit to old, but should be usable, so if you can install Debian BookWorm, open a terminal:
sudo apt update
sudo apt upgrade
sudo apt install linuxcnc-uspace
That will install everything needed.

Regarding search engines, use google and duckduckgo, google could not find an stl using the exact file name, duck showed it as the first result. For some stuff it is the other way round.
In general, all are useless.

I am trying to do a closed loop spindle configuration, but the spindle menu is locked not active. What should I do for +-10v sample configuration . Thanks!
 

Boards that don't have a spindle interface the spindle sections is not enabled. A sample spindle would depend on what board it is.

Hi,

I found a paper that has the info to create a 3d clothoid 4 segment spline. Ideal to create 3d fillets for gcode.

Now is anyone able to help convert this paper into c or c++ code?

Update Work Offsets with G Code

Category: G&M Codes

I think this would require a custom Gcode using a remap. I made an example remap for a command 'G10.1 Xn Yn Zn'

Try this:

Add this to the [RS274NGC] section of your ini file:
          REMAP = G10.1  modalgroup=1   argspec=xyz  ngc=g10_increment

Create a new file with the Gcode below and save as 'g10_increment.ngc' to a folder in your
[RS274NGC] SUBROUTINE_PATH   
o<g10_increment>sub
M66 L0 E0                    ;force sync, stop read ahead    

o100 if [EXISTS [#<X>]]      ;check for X-word, set to zero if missing                       
o100 else
    #<X> = 0                                                  
o100 endif
o101 if [EXISTS [#<Y>]]     ;check for Y-word, set to zero if missing  
o101 else
    #<Y> = 0                                                  
o101 endif
o102 if [EXISTS [#<Z>]]     ;check for Z-word, set to zero if missing  
o102 else
    #<Z> = 0                                                  
o102 endif

; calculate which parameter contains the current X,Y,Z offset values
#<x_current> = [5201 + #5220 * 20]
#<y_current> = [5202 + #5220 * 20]
#<z_current> = [5203 + #5220 * 20]

; add the passed X,Y,Z words to the current offset values
G10 L2 P0 X[#[#<x_current>] + #<X>] Y[#[#<y_current>] + #<Y>] Z[#[#<z_current>] + #<Z>]

M66 L0 E0                   ;force sync, stop read ahead
o<g10_increment>endsub
m2

Note:
This will always apply to the currently active offset system.

You could use another unallocated  GCODE :
linuxcnc.org/docs/2.9/html/remap/remap.h...:unallocated-g-codes

You could extend this to query the state of G90/91 and/or add a  'P' word to pick an offset system other then the currently active one.
