[00:07:31] <skunkworks> what does processor.maxstate=1 do?
[00:07:43] <skunkworks> that is a new one. Power state?
[00:10:18] <Tom_L> googling indicates something to do with temp
[00:11:06] <Tom_L> lowering performance?
[00:14:07] <Tom_L> max_cstate=X option in the kernel line of /boot/grub/grub. conf . In order to save energy when the CPU is idle, the CPU can be commanded to enter a low-power mode. Each CPU has several power modes and they are collectively called “C-states” or “C-modes.”.

[00:16:31] <Tom_L> https://access.redhat.com
[00:16:40] <Tom_L> i'm sure debian etc are similar
[00:16:49] <Tom_L> fair description of it though
[00:18:09] <Tom_L> talks about idle=poll too
[00:18:39] <Tom_L> makes it more power hungry
[00:19:07] <Tom_L> might be a bad idea for something like the rpi4...
[00:22:54] <skunkworks> my pi gets warm....
[00:22:59] <skunkworks> wow

[00:23:49] <Tom_L> well my asrock is fanless so i'm wondering if that's a good idea to try on that or not
[00:28:32] <Tom_L> huh, maybe i'm not using the asrock on it.. this pc has that board
[00:28:43] <Tom_L> i'm wondering what i'm using now
[00:29:16] <Tom_L> maybe the intel D525

[03:10:53] <Loetmichel> they are not "news networks" but full program thoug
[03:10:57] <Loetmichel> +h
[03:11:26] <CaptHindsight> Vielen Dank

[07:20:15] <XXCoder> interesting https://twitter.com
[07:25:45] <pink_vampire> cool
[07:26:10] <pink_vampire> do you know where can I find plans?

[07:38:05] <pink_vampire> any idea how to make this in linux cnc?? https://youtu.be
[07:39:00] <XXCoder> spindle as axis
[07:39:07] <cpresser> pink_vampire: have a spindle-encoder and be done with it.
[07:39:20] <XXCoder> some machine have linked axis to sync
[07:39:25] <pink_vampire> I have the spindle as C axis
[07:39:36] <cpresser> http://www.linuxcnc.org 6.1
[07:40:12] <cpresser> then this http://www.linuxcnc.org

[07:41:42] <pink_vampire> cpresser: https://i.imgur.com
[07:41:59] <pink_vampire> this is how the spindle work
[07:43:01] <cpresser> one solution is to wire z-axis-pos-cmd to c-axis-pos-fb
[07:43:01] <pink_vampire> but you need to talk to the C axis in degrees.
[07:43:16] <cpresser> put a multiplier component in between
[07:43:23] <cpresser> to convert units and set pitch
[07:43:49] <pink_vampire> not really sure
[07:44:05] <cpresser> perhaps also have a mux that allows switching z-axis-pos-cmd back to the motion output, so you can use both configurations without restarting
[07:45:30] <pink_vampire> what is z-axis-pos-cmd?
[07:45:48] <cpresser> a HAL signal.
[07:46:36] <cpresser> most likely the name is not correct, I don't know the exact names out of my head
[07:46:45] <cpresser> consider this as pseudo-code
[07:47:34] <pink_vampire> is that something that is built in to linuxcnc?
[07:47:51] <cpresser> HAL is buildin.
[07:48:26] <pink_vampire> I mean the "z-axis-pos-cmd" signal
[07:48:54] <cpresser> yes. there will be something like this in your hal configuration
[07:49:02] <cpresser> open the hal viewer and inspect the signals
[07:50:24] <pink_vampire> ok lets see
[07:52:07] <pink_vampire> zpos-cmd?
[07:52:23] <pink_vampire> Type float
[07:52:42] <cpresser> sounds plausible. move your machine around and see if it changes
[07:52:43] <pink_vampire> Value -58.00189
[07:53:48] <pink_vampire> yes, it is moving,
[07:54:07] <pink_vampire> it's not the same value as the Z axis DRO
[07:54:27] <cpresser> because of offsets, touchoff, ....
[07:55:12] <cpresser> the DRO value is most likely also somewhere in HAL.
[07:55:34] * cpresser would need to look into the docs. I don't know this out of the back of my head
[07:57:57] <pink_vampire> ok, but at least I have a start - thanks

[10:53:57] <jymmmm> Firefox Dev's are getting worse and worse these day. That whole FORCE you to restart to finish update is BS. Now they've removed the manual update option in settings, but it's still in ABOUT:CONFIG, app.update.auto, and set to FALSE

[11:11:36] <jymmmm> WOW it's amazing how many things are NOT available on amazon
[11:18:56] <Rab> Orders are being pushed out by a month, too.
[11:19:47] <Rab> I had seen reports of that, then I placed an order on March 23 and it's alleged to be arriving on April 24.
[11:20:41] <Rab> All items FBA and in stock, but not a Prime order.
[11:21:13] <Rab> I suppose that's on me for funding Jeff Bezos's alimony payments.
