Sounds like you have both 7I77 processors in setup mode
That will not work, they must be in operate mode:

W4 and W12 in left hand position

Did you try step_type 2?
This is quadrature mode and has square wave output.
(if the stepgen scale  is set to 1, the output frequence is directly
settable in Hz)

Also with OPTOs you need to limit the input LED current
to the minimum required to get the quickest turn off,
maximum frequency.

"I believe linuxcnc will just not write the axes that are zero."
I noticed in the Wiki there was a comment that the format had changed in previous versions. So I assumed that the table is in correct format and not corrupted.

"The comment line is probably limited to a certain length in linuxcnc - though I can't find that limit at the moment. QtDragon is less limiting on comment length."
The reference to line 231 appears to be coming from the qt_auto_probe_tool.ngc file. This is lines in that file with preceding line numbers:
 

225 ; return to original tool-tip position, but using new z-offset
226 ;  (DEBUG, Return to original tool-tip position using new z-offset: #<local_start_x> , #<local_start_y> , #<local_start_z> )
227 G53 G0 Z[#<_ini[VERSA_TOOLSETTER]Z_MAX_CLEAR>]
228 ; now use original (modal)coord system to go over to xy
229 G0 X[#<local_start_x>] Y[#<local_start_y>]
230 ; and finally down to the (already offset) z coord
231 G0 Z[#<local_start_z>]

"Am I understanding right, if you cancel the G54 offsets the process works once?"

My gcode file has a G54 line in it from Fusion 360 but that is after the tool change. So once it fails, I click "Clear all" the error gets cleared and I click start at line 1 it runs without error.

I believe that this INI line may be part of the problem(no G43)??
RS274NGC_STARTUP_CODE = G17 G21 G40 G80 G90 G94 G54 G97 G64 P0.025 S5000

Here's the lines of the gcode that I am running:

7i92+7i77 basic comms again

Category: General LinuxCNC Questions

Hi Guys - 7i92+7i77 combo. Sorry to have to seek help so early in my project. Im trying to take it all step by step but hit a brick wall with the comms to the 7i77. It isnt being recognised by the the 7i92. I just have the boards on the bench powered from a lab power supply at the mo. I'm just using mesaflash on 192.168.1.121 with the basic linuxcnc - no realtime yet - and flashed with 7i92+7i77X2D.bin all seems OK but when I use --sserial --verbose  or --readhmid there is no mention of the 7i77. I have the two cards directly connected with their X25Dshell's - no cable - and +12V Field.
LED's - On the 7i92 Ive got the +5V LED and variously some of the user LED's lit (these vary when I interogate the card - bit odd)  and on the 7i77 LED's - +5V,Field Voltage,CR15 Field Activity, and CR16 Field I/O fault which is Red. All these LED's permanently on. Worryingly LED 6 and 7 are not on - in the manual there are +16V and -12V monitors and should be on??
Should basic comms be working as above or should I have some ini or hal commands to get things going. 
Thanks for all your help...

i would check you slides on your z axis, sound like something loosened up on the lower part of the z axis. if the machine is 10 years old and shop built that would be the most like cause. 0.008 could just be a loose screw on your slide

Hi Arciera,

To verify i did a fresh clone into a dir named : ~/test.

1. Build linuxcnc as usual, and did a sudo make install to finish the installation.
2. Build the clothoid-1 lib. (had to empty the build dir, then cmake.. make -j4.  eventually do a make install for system wide.)
3. Create build dir ~/linuxcnc_trajectory_planner/cmake/build  
4. cd into this build dir. then : cmake.. make -j4    and do a make install
5. Run the ./build.sh script.
6. Linuxcnc runs here.

I think you did not do a make install for installing (overwriting) the modified motmod.so component.

Ok good luck.

i cant get the pulse to go though the OPTO, least not the cheap ones. thinking the pulse time is to fast sure there is a way to turn that but it is cold out there right now, the manual shows a npn/pnp switch, freeding a opto.

Thanks a lot but these is not necessary, I have not problem on these .... but now is well done so can add system folder cancel mine so everyone can build it on QT6  ...

Any how if eliminate halwidget from project problem remain ... so my attached project .... (finally I purge it and with some fortunes i see is not problem of code ... but only a compile problem .... not find perhaps) ..... github.com/bkt-it/Lcnc-test-qt6 .....

I find that problem become from no linking on iniaxis.o .... and these research suggest me somethings not work on linkages from .hh and .h file .... but not an expert ... or not so mutch to solve the situation ....

Warning: Spoiler!


Thanks a lot

Hi,

I tried opening your ethercat-conf.xml and it has invalid syntax...see attached screenshot.  Try fixing that and see if it works.

When you boot the rt kernel from the sd-card it recognizes your nvme?
With the non rt kernel it does boot from the nvme?
Are you sure you're writing the right uboot to mtd?
Here are some others:
github.com/7Ji/orangepi5-rkloader/releases/tag/nightly
Download: wget github.com/7Ji/orangepi5-rkloader/releas...ddr-v1.16-spi.img.gz
extract:      gzip -d rkloader-mainline*.gz
erase mtd: flash_erase /dev/mtd0 0 0
write mtd:  dd if=rkloader-mainline*.img of=/dev/mtdblock0 bs=4K

Uploaded an image (without hw acceleration) with the rt kernel already installed.
For better latency results add the following line to armbiEnv.txt :
extraargs=isolcpus=5,7

and disable screensavers/standby etc

Installed the kernel on my OPI5 and installed the (sata) bootloader from that image to the mtd and it still boots from the M.2 sata. The OPI5 plus also still boots from NVME.

This seems very unlikely to be a LinuxCNC issue, but I'm stuck, and there are lots of sharp people in this forum. I'm trying to cut 20mm diameter holes 3/4" deep in MDF. The bottom of the hole is around 0.008" smaller than the top.

I have a 30x30" cnc router that I designed and built 10 years ago. It uses ball screws x and y. I'm changing my spoil board so it has spots for precision dogs. Cutting the dog holes has turned into a project. I'm getting decent accuracy at the top of the hole, but around 8 thousandths less at the bottom. The holes are about 20mm x 3/4" deep in MDF. I'm not saying this is a new problem, I haven't done precision holes before, so have no idea if this is new or old.

Hole cutting: With a 1/4" straight Whiteside carbide bit (2 flute), each level is cut with 50% stepover. The 3/4" depth is done in 4 layers, 0.2" each, leaving a 0.001" skin. Each layer is cut conventional, with a single additional pass on each layer (finish pass). After the hole is cut, there are two additional finish passes done at full depth, one conventional, one climb. The inside of the holes looks pretty clean.

My CAM software (DeskProto) does not use circular arcs, it uses a lot of x-y positions to cut a circle. They are very nice circles to the eye, no segmentation. I searched the gcode to find max/min x and y, they are correct for the size hole I want. I did a hole from gcode produced by Kiri Moto, same results

My first thought was bit deflection due to loading, but the final two finish passes should have very little load.
Another possibility is if my cutter was ground with a small taper. I don't measure anything like that, the flutes are parallel the full length (1" long flutes).

I've tried a 1/2" bit and a brand new 1/4" Whiteside, still the same sort of taper.

I'm at a loss, please advise.
