Thought you couldn't read datasheets ?

DIMM or PCIe slots, great way to bump the price up.

I upgraded to Debian 12 and LinuxCNC v2.9.3 and find I can no longer build.

Linux debian2 6.1.0-22-rt-amd64 #1 SMP PREEMPT_RT Debian 6.1.94-1 (2024-06-21) x86_64 GNU/Linux
Downloaded 2.9.3 tarball from git yesterday.

I kept pretty good notes on building with 2.8.x and can't find anything I previously encountered related to this. I can Make just my own code but when I do the full Make I get the following:

I'd appreciate if someone could suggest how to proceed. This doesn't seem to involve any code under my control.

Yes, The Pi gets the most recent 6.6.44 kernel

Normally you would get that message if you have offset probing enabled and are less than the Y axis offset distance from the Y axis maximum.
These settings are in the .prefs file.If these values are correct could you post the backup file created from the BACKUP button on the SETTINGS tab.

Hey Scott, about adding the encoders. The RP2040 W5500 firmware is similar to the STM32 W5500 firmware, in the sense that they both use the pingpong buffer thing. Ive been trying to add encoders/PWM to that firmware, but Im encountering an issue. I dont know where to send the data. There are examples for digital in/out and stepgen stuff, but there is no examples for PV/SP modules. Where ever its going, it should be similar for both firmwares.

Here is my initial attempt at encoders, but I cannot yet get it to compile
github.com/cakeslob/Remora-STM32F4xx-W55.../Src/modules/encoder

Here is what Drew and I were working on for PWM, it compiles, but doesnt yet work either.
github.com/cakeslob/Remora-STM32F4xx-W55...main/Src/modules/pwm

I was wondering if you could give me a few pointers? (pun intended)
But seriously, where do we send the data for PV/SP? The pointers are different than the other versions of remora, and I am stuck.

Just to reinforce how messed up this is, the MESA shipping costs for one board to Australia, what an absolute joke: 

RIP you cool, clean, compact, integrated Mecanix board.

In other news, has anyone seen these Analog Crosspoint Switch Array ICs, thinking out loud if they could be useful...AD75019 is pricey but two MT8816 gets you to 16x16 for a lot less money, I ordered four PDIP MT8816 because I couldn't help myself?

Thinking out loud some more (it's what I'm best at, not so great at doing lol) is some kind of generic "slot" based expansion system the way to go, an FPGA backplane board with something like DIMM or MiniPCI slots for IO...jumper wires and ribbon cables be gone!

I’ve installed ISE 14.7 on both Debian Bookworm & Mint 21, trick to get the installer going is to install libncurses5 and after the install to get a licence setup you need to rename your Ethernet port to eth0. To get a licence you need to register with Xilinx now AMD.

here is a youtube video for I think is the originator of the design I based mine off of he also made a
program for generating the G-code to run the thing.  Pretty cool.

 

You have the PID P terms set so high that they will cause oscillation.

You should use 1/servo-period which is the pncconf default = 1000
for a 1ms servo thread rate.

The physical meaning of a 1/servo thread P term is that position errors
are corrected by the next servo thread invocation. A value of 10000
(with a 1ms servo thread rate) means that a sensed stepgen position
error will be overcorrected by a factor of 9, leading to oscillation.

In addition:

setp hm2_7c81.0.dpll.01.timer-us -50

should probably be changed to

setp hm2_7c81.0.dpll.01.timer-us -200


 

Changing the encoders pwm gens and step gens made a HUGE difference...

Not sure I understand why... sounds like I need to do some reading on how that driver or maybe linuxcnc works... recommendations?

My steppers now move... unfortunately they are stuttering and making a horrible noise.... I suspect that is all about tuning the settings. If so can you point me to a document on how to develop the tuning parameters?

THANKS!!

hi...I just installed linuxcnc debian 12 ( bookworm)....had no internet so skipped mirror...now I have connection but do not see how to set up mirror for things I may not have installed as a result on skipping...Thanks,

Rick

Dear colleagues,I´m invoking here the experts in an attemp to make my PC to boot.

I´ve sucessfully installed the newer Linux cnc version (2.9.3), but when booting after the install, I get a message saying "Loading initial ramdisk", then a short message "x86/cpu: VMX outside TXT) disabled by BIOS" and then the screen turns black and it never recovers.

I´ve tried enabling virtualization in the BIOS, just in case. I´ve tried using a different display output connector......still nothing.

The install has been done on a Lenovo tiny M600.What am I doing wrong? I´m about to throw the pc through the window.
Thank you in advance! 

Hi,
I cant understand what options do I have

Currently Im using hal_manualtoolchange for semi manual tool change
I have ATC, but at the moment I dont use slots / pockts, instead Im using go to toolchange XY, ZMax, and change the tool through button on pendant  / QTDragon MDI_COMMAND
But when Im inside hal_manualtoolchange dialog, non of these options works. It blocks any activities

May someone more familiar with QT/LCNC desing point me to the right direction

My sugestion / questions would be
1. Create a custom dialog (if its possible to be an additional to the code / not replacement) with additional button. 
2. Somehow ublock cnc pendant button exceution
3. something better I dont know about

The first problems I see are with your joint/axis assignments and your home sequence numbers.

In your [TRAJ] section of your ini file you have
COORDINATES = X Y Y Z

This will assign joint 0 to the X axis, joints 1 and 2 to the Y, and joint 3 to the Z.
That is perfectly acceptable, but it seems to get confused below that in the Joint and Axis sections of the ini file.

To configure the Y axis to use joints 1 and 3 your would need:
COORDINATES = X Y Z Y

First which joints do you actually have connected to which axis?

2nd the joints that are assigned to the Y axis must be given matching negative numbers for their HOME_SEQUENCE = setting.

If you are wanting the Y axis to home 1st, don't use HOME_SEQUENCE = 0. It is not required that zero is used in the home sequence. For a duel joint gantry axis, use HOME_SEQUENCE = -1 for both of the joints assigned to the axis(or -2, or -3...)

Usually the Z axis is homed first in most configurations to make sure that the spindle is out of the way for the other axis to home later.

If you are using joint 3 as the Z axis I would suggest moving the [AXIS_Z] section down just above the [JOINT_3] section in your ini file.

in your hal file it looks like you have Z connected to joint 2. And I don't see a home switch connection for joint3 (both of the Y axis joints must have seperate home switch inputs from each other.)
