How much of it was written with AI?

Quite right. A 25% antifreeze solution is probably a good approach but I would suspect there is just so much chelating ability for that dilute a solution. Compound that with the likelyhood most people are going to replenish it with tap water, there in lies the big mistake.

Again your quite right. I guess my real focus was to give others a heads up on a possible fix without tearing it appart.

regards

Most of the spindle manufacturers I've delt with recommend a 25% solution of some kind of antifreeze. Not so much to prevent freezing but for the additives for corrosion inhibition and pump seal lubrication that are included with them. While most don't specify an automotive product, they generally are not much different from standard car antifreeze. (Using straight tap water in most kinds of cooling systems is asking for trouble.)

 
 

While I focus on open source software, I'm at least glad to see a one-time payment perpetual license at a reasonable price (no subscriptions!) and linux support (even if it is AppImage..). 

Good luck.

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..

We were too broke to keep paying CAM subscription every year so we built this. Its not free, but 200 dollhairs gets you in perpetuity a 3 and 4th Rotary axis CAM. For what its worth, learnt everything from here. 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.
