4-Gang 1-Way Switch To Control 3 Power Supplies and a Router Independently

Category: Computers and Hardware

Rod, drives should be mounted vertically, as noted in their manuals.

Yeh, that is due to a bigger stuff up. The enclosure is 400 x 400. I removed the backing plate and I carefully marked out all mounting bolts and inserted nutserts everywhere to mount everything. Then mounted everything only to find the backing plate was not square like the enclosure! So the plate is rotated 90 degrees from where I planned.
400 x 400 is really too small but it was what I could get at the time due to COVID. Made for a really messy install because of no room for slotted conduit

Spindle control not showing in Axis window...

Category: Basic Configuration

OK - I now have spindle control...

@tommylight - your post(s) about 'no spindle' configurations and suggestion to make a new config finally helped my 'through the forest'.

Not that I would ever 'bite the hand that feeds me', I have to ask if you were coaxing me in to discovery? I mean - how much more effort would it have been to state something like "the line in you HAL 'net spindle-on      => parport.0.pin-09-out' does not initiate the spindle. It defines or assigns a pin to use (pin 9), but it doesn't actually make the pin 'do anything'. What you need is a line that connect the assigned pin to a function like this: 'net spindle-on spindle.0.on => parport.0.pin-09-out'"

First - I am just 'making this up' because I really do not understand the structure and syntax of the lines in the HAL file (something that I really think would have helped me in my discovery). Please feel free to delete this post or tell me to do so because I certainly do NOT want to confuse anyone else.

If this kind of documentation already exists somewhere - I certainly did not find it, but if you point me to it, I will be certain to explore. Meanwhile - thank you both again for your assistance and direction to resolving my issue!

Regards,
Arden

Also could you explain how your physical setup for homing of the C axis / spindle? It is something I am having trouble with after modifying your HAL and INI (which I will attach here).

here is a picture of my physical manual, its slightly different than the online manual. However, do you think it actually does work and this physical copy of the manual is wrong?Also just to clarify - are you also saying that because my current encoder is not 1:1, that it will not work?I can go ahead and try to solder on the wires to my servo driver and test it out

Can MDI_COMMAND entries be explicitly numbered?

Category: General LinuxCNC Questions

I wrote that because of your argument that referencing MDI_COMMANDS explicitly would make the ini file "more standards compliant".

Ideally every GUI should provide it's own hal pins to handle the functionality of 'halui' (which is actually a separate user interface).

There needs to be motor power on for the TMC drives to configure. the CS pins are the Rx pins, but leave them in uart mode. the TMC spi is on the same channel as the comms SPI so idk what will happen if they interfere or something.
but first step is working out comms
does it connect to linuxcnc yet with the drivers in uart?

take it to here,

but if flashing the config worked before and now it wont work, you will probably need to do a full chip erase to overwrite the sector, then reload the firmware and config.

using HAL to correct axis errors

Category: Advanced Configuration

I wanted to bring this thread up to date, in case anyone finds it and finds it useful.  I recently upgraded my mill from 2.7.4 to 2.9.4, which of course brought in the joints axes changes.

Those required some rework of my skew corrector.  The component module itself was unchanged.  It's in a post above .

But the linkage into HAL did change, due to joints axes, and the introduction of pid.

First, 2.7:      the original HAL had a fairly simple connection between motor and stepgen:
  ypos-cmd
      axis.1.motor-pos-cmd ==> stepgen.1.position-cmd
  ypos-fb
      stepgen.1.position-fb ==> axis.1.motor-pos-fb

  xpos-cmd
      axis.0.motor-pos-cmd ==> stepgen.0.position-cmd
  xpos-fb
      stepgen.0.position-fb ==> axis.0.motor-pos-fb

I was able to simply insert the nonsquare function block into the middle of each Y axis signal path, and tap into the X signal path.
 ypos-cmd
      axis.1.motor-pos-cmd ==> nonsquare-table.y-in
  ypos-cmd-adjusted
      nonsquare-table.y-out ==> stepgen.1.position-cmd
  ypos-fb-adjusted
      stepgen.1.position-fb ==> nonsquare-table.y-fb-in
  ypos-fb
      nonsquare-table.y-fb-out ==> axis.1.motor-pos-fb

  xpos-cmd
      axis.0.motor-pos-cmd ==> stepgen.0.position-cmd
                           ==> nonsquare-table.x-in
  xpos-fb
      stepgen.0.position-fb ==> axis.0.motor-pos-fb
                            ==> nonsquare-table.x-fb-in

The newer LinuxCNC path in 2.8/2.9 is a little more complicated, with the introduction of the PID mechanism.
  y-pos-cmd
      joint.1.motor-pos-cmd ==> pid.y.command
  y-output
      pid.y.output ==> hm2_7i96.0.stepgen.01.velocity-cmd
  y-pos-fb
      hm2_7i96.0.stepgen.01.position-fb ==> joint.1.motor-pos-fb
                                        ==> pid.y.feedback

  x-pos-cmd
      joint.0.motor-pos-cmd ==> pid.x.command
  x-output
      pid.x.output ==> hm2_7i96.0.stepgen.00.velocity-cmd
  x-pos-fb
      hm2_7i96.0.stepgen.00.position-fb ==> joint.0.motor-pos-fb
                                        ==> pid.x.feedback

Integrating the nonsquare function in the new HAL is similar, butasymmetric.  TreIn the output direction, the nonsquare function is inserted between the joint and pid (which then feeds stepgen), but in the feedback direction, we insert between stepgen and the joint.

Regardless, the new function is inserted just after (cmd) and before (fb) the joint command.  The X control for the new function is similarly attached directly to the joint function.
  y-pos-cmd
      joint.1.motor-pos-cmd ==> nonsquare-table.y-in
  new-y-pos-cmd
      nonsquare-table.y-out ==> pid.y.command
  y-output
      pid.y.output ==> hm2_7i96.0.stepgen.01.velocity-cmd
  y-pos-fb
      hm2_7i96.0.stepgen.01.position-fb ==> nonsquare-table.y-fb-in
                                        ==> pid.y.feedback
  new-y-pos-cmd-fb
      nonsquare-table.y-fb-out ==> joint.1.motor-pos-fb

  x-pos-cmd
      joint.0.motor-pos-cmd ==> pid.x.command
                            ==> nonsquare-table.x-in
  x-output
      pid.x.output ==> hm2_7i96.0.stepgen.00.velocity-cmd
  x-pos-fb
      hm2_7i96.0.stepgen.00.position-fb ==> joint.0.motor-pos-fb
                                        ==> pid.x.feedback
                                        ==> nonsquare-table.x-fb-in

Problema de latencia y 7i96S

Category: Español

Do you get latency warnings when running LinuxCNC?
Does the connection to Mesa board get dropped?
Latency does not look good, see if it can be improved by using isolcpus, but first enter the BIOS and disable anything with power saving and hyperthreading and TPM.
