Is that quote from the likes of PCBWay and JLCPCB, or ?

Hmmm. I might be able to SLS print the way covers from nylon. Looking like around $400-$500cdn shipped for the X axis in the render. That probably cheaper and better than anything else except bellows which are cheap but terrible. Only downside is you don't have a super smooth surface for the wiper seal, but maybe a little brush seal might be better anyway.

Probably in the $1500cdn area for all covers on the machine. Plus another $500 for a printed tool magazine.

And then if a customer smashes a part, they can just print a new one. Very plausible.

Not that i know of from reading here, but i have never used isolation, ever, i have access to plenty of PC's and laptops so if any show bad latency i run 3D printers from it!

If the drives are some really off-brand proprietary type, then it could be difficult. If they are a common brand where the documentation can be turned up, then they can often be reused. First, you need to determine what type of signals control the drives. The common schemes are analog velocity control (sometimes called +/- 10 V), step and direction, and PWM. Do the encoders feed back directly to the drives? Do the drives then send a copy of the encoder signals to the CNC control? Are there tachometers on the motors? Are there even encoders on the motors? If no encoders, then clearly the motors are steppers. If so, then there are literally hundreds of stepper drives out there that can likely drive those motors. If there are encoders, then you need to determine if the motors are DC brush type or brushless.
Give us make and part number, or even just photos of the motor nameplates and we can help.

So even the drives can be re-used?

That would be my preference. I sure hate to waste the good electronics. It's the software that's the missing piece which is where I was hoping LinxCNC could pickup. I'm already a Linux user which this would also be a perk in my book.

Ahhh I see now, thanks for that. Haven't really looked at the ethernet code (working out the ssreial code for the 7i90 was a journey in itself, but the ethernet code would mean also coming familiar with the etherent chip), for the price of trying to implement that at home it doesn't make sense.

I really I didn't swap from an electronics trade to carpentry when I was a teenager......but being outside and using my hands was a greater calling.

Linuxcnc is miles ahead of what is running 3D printers.

I've been running my 3 axis mill for years with no limit, homing switches or position feedback, the parts come out fine.

Without seeing the actual error it's hard to tell. I'd just boot into a live session and use fdisk to remove the existing partitions and try the installer again.

If you are unsure about anything, and I'm going to be that guy, the documentation is there, full of information. The devs spend time writing them, so give them a read, even after all these years I still read them.

it does work. i was just about to do it until you told me that thanks. are there any drawbacks to doing it anyway?

I do that, often, if the drives and motors are in good working condition.
Still, to know exactly we would need much more info about the drives, or pictures and videos of ... everything.

I am curious how practical it would be to re-use much of an existing CNC Router. The problem is that it used software that seems unobtainable.

I'm assuming this means that the existing motor control will be trashed. Maybe I can use the power supply.

Would I be able to adapt the existing motors to new driver boards and run LinuxCNC?

I just hate throwing out good components.

Coming along.
Anyone ever have custom way covers made?

what isolcpus settings do i need for an 8 core ryzen machine?

I use Ryzen 7 3700X CPU, never had to do isolcpu, it just works. Same on Ryzen 5 3600.

@Hi,

Tonight i went to the production machine with a hard-drive for testing hal-core.
After figuring out how to setup hal parport and run posix realtime etc for a few hours,
i managed to run the machine on hal-core.

Most of you know halcore uses no python and is very compact coded.
It run's posix realtime, so i am happy for today.



github up to date

i have not installed everything yet. i will get to that and let you know how the latency is after running it for a day or so. thank both of you for all your help.

Absolutely brilliant. thats the ticket right there. even without isolcups. its been running for several hours now and i haven't gotten the dreaded error finishing read error.
