Hi Peter / Mesa Support,
I am setting up a machine using a 7i76e and I need a custom bitfile for my expansion board configuration.
My hardware layout is as follows:

• Motherboard: 7i76e
• Expansion Port P1: 7i78 (Step/Dir expansion)
• Expansion Port P2: 7i89 (Multi-channel encoder board)

Could you please generate a pre-builtfile (and correspondingfile) for this specific configuration?
Thank you for your help!

TWP is the 'tilted work plane' feature, you are likely after the TCP mode that keeps tool tip position stationary when the tool orientation and offsets change.
If your CAM is capable of handling tool offsets then you can keep using trivkins.

I'm sure there others out there who have or are going to run into the same problem I had.  In the spirit of sharing I'll give you my remedy which was much easier than I thought it would be.
Let me preface this by saying my 2.2 kw spindle was not allowing any flow through it from the cooling pump.  I tried blowing air through it, reaming the port and even acitic acid which didn't seem to do anything.  I was getting prepared to do a tear down which I really didn't want to get into.  I read everything I could on the net and as a last ditch effort I bought a quart of CLR descaler.  I managed to force some into circuit, shut the pump off, and left it over night.  Next morning I turned the pump on once more, not expecting anything to have changed.  To my great surprize the pump took off linke a race horse and started pumping out the CLR and all the crud it removed.  
The lesson here is that it was my fault for not using deionized water and using tap water.  Big mistake!
As I don't use the machine a lot I was always replenishing the system with tap water, about the worste thing you could do.

Recommendation.:  Use only DI water,  If possible make it a closed loop system.
Good Luck!

Disclosure first: I'm the developer and Takshak is a commercial product.
I'm posting in this section because the rules allow it — mods,
please move this if it belongs elsewhere.

What it is: a CAM package for 3-axis work and 4th-axis rotary. You bring
a model, it finds the features, you pick operations and tools, and it
posts g-code. It runs entirely on your own machine — no cloud account,
no internet needed after activation, nothing phoning home while you cut.

Posts it ships with, eighteen in all:

Shop and DIY controls — LinuxCNC · Mach3 / Mach4 · GRBL · Masso ·
Centroid · Tormach

Industrial controls — Fanuc (generic) · Haas · Mazak · Doosan ·
Brother Speedio · Mitsubishi · Fadal · Siemens 840D · Heidenhain TNC ·
Okuma OSP · Fagor · Hurco

Seventeen of those eighteen also ship a ready-made inch variant, so you
pick your control and your units and you're done. The exception is
Heidenhain TNC: it writes Klartext, and I won't ship a Klartext inch
post until I've checked the TNC feed-word convention against a real
control. I'd rather ship one less than ship a guess.

Also worth knowing:

- Rotary is a first-class part of it, not an afterthought bolted on.
- It runs on Windows and on Linux. The Linux build is a single AppImage.
- It's a one-time perpetual licence, not a subscription. $199 for the next 30 days, $399 later. If it's no good, there's 30 days to get your money
back, no argument.

What it isn't: it's CAM, not CAD. And it's new — 1.0.3 went on sale this
week. I'd rather say that plainly than have someone find out.

Do you have any real life examples?
Fanuc post processor?
Is there a trial version?

So IF I were able to get tool offset for 5 axis in CNCToolkit and run in trivkins.....would not having the TWP give same results?

Thanks for help here...I am a little over my head here but need to learn..

Perpetual License, Automatic Feature Recognition CAM for an introductory price of $199 (until 1st October).
3 Axis and 4th Rotary Axis
I know its not open source but was advised by a mod that I can put this here.
Sales will help us open more engineering sw that everyone can afford. Thanks.

For this geometry there is this sim config in the current development branch:
github.com/LinuxCNC/linuxcnc/tree/master...ndle-rotary-nutating
I would suggest you have look at that before you start looking at changing over from trivkins.

You should also be able to install the kinematics component on version 2.9 using 'halcompile' (for which you may need to install the linuxcnc-dev package). The component can also be found here:
github.com/Sigma1912/LinuxCNC_Demo_Confi...ary/xyzacb-snrtr_twp

For your case, you would set the nutation angle to 90° and ignore the C axis. TCP will work just fine but the TWP feature will currently only work for the head rotation.

I might have one in my spare parts drawer, I'll check when I'm in the shop.
Pick it up in Berlin or send me your address at shu at admin dooot world

I have done it in the past manually, it's not trivial. Best way is to edit the g-code and reload, trim away everything after the preamble to the last plunge move.

It's not possible to just resume the file from the point it ended as that is most probably right in the workpiece without a safe direct line from the tool height probe position. So we need at least a safe ramp/plunge movement. And the preamble needs to run again, to use the correct tool height offsets, tool diameter compensation, bring the spindle up to speed...

I don't think there can be a generic resume-at-position for this that fits all. Some tools that have a certain orientation or don't enter the workspiece colinear to the spindle, e.g. t-slot cutters, profile cutters in general, taps. And then there's five axis machines.

Have you checked the digital inputs? 
there is origin and pos/negative limit set as default functions for the digital input. If the limits are setup for NC wiring and nothing is connected, it might become an issue

Where is it called from and what does the code around it do? send a URL into github
I don't think it can simply be  ignored.

The code above displays message only once.
This may mean either a serious problem or a one-off event with no impact on further work.
This, in turn, means that this message says nothing, warns against nothing and is unnecessary.
The right thing to do is to run latency-test or latency-plot for a few hours immediately after installation, which will clearly answer the question whether the hardware and software can be used safely.

"Unexpected realtime delay on task" means that linuxcnc did not get everything done in the allotted 1ms time of the servo thread. This is nothing to do with the LinuxCNC application.

In kernel traces I did a long time ago on an i5 machine with Bookworm, Linuxcnc typically took 200 us to execute the servo thread and sleeps for the remaining 800 us. That 800 us is the safety buffer for real time tasks. Sometimes there is a Linux task that consumes a lot of the  CPU time which impacts on the servo thread and LinuxCNC does not have enough time to get everything done in time. Then the system reports the realtime delay and generally disables linuxcnc (so long since I have experienced this myself I can't remember). There are many possible tasks that can cause this.

One new source I found this week is that if the wifi has poor signal strength, a NetworkManager task fires looking for any stronger wifi signals every 30 seconds or so and causes a latency spike every 34-36 seconds. Because CNC machines are not generally wandering the aisles of a corpporate workspace, its a no brainer (and safe)  to disable this service. Linux obligingly provides an obscure process to do that.... Don't ask me what it is, I've forgotten already.

Addendum:
I took a deeper look (again) into the datasheet of the motor driver. There is a green LED that flashes at a rate of about 2s. According to the datasheet, this means, that the motor power is still off. When the power is on, this LED should light up constantly without flashing.
Reading the statusword of the driver shows a value of 0xb094. According to the cia402 specification, Bits 3, 5 and 7 are 1. This means OP is enabled, quick stop is active and there seems to be a warning. Maybe this is helpful.
