Your absolutely correct, "use distilled water" not deionized water. As I dig into this I am also finding quaternary ammonium compounds seem to be very effective compounds with no corrosive effects. Many people like myself live in warmer climates (Sout west Florida) who don't need antifreeze qualities and would like a relatively inexpensive way to keep the cooling system from becoming an algae garden. Short of manufacturing one myself I suspect RV atifreeze is probably the simplest way to handle this.

Thanks for your input.

Afternoon internet.
I have just bought this and now have the fun task of retrofitting. I'm wondering what hardware you guys would use. obviously due to the 3 phase steppers ill be using most of the original gear.
Main issue is I'm in UK and don't want to wait for a mesa card from America nor pay £300 quid for one. unless its worth it.
I see a few control board options

Option 1 EC500 remora about £100pros 24V card logic I/O easy. Cons pure china lottery
option 2 MESA 7I76EU about £300 Pro; proven card, known to work, can copy what people have done before. cons price / waiting time.
option 3 Parallel port Pro, cheap crappy board will get going quickest, cons bulky tower pc, will never be happy.

Control computer
Pi 5, from what I've read with ethernet connections theses are good. Pro small, Con dunno if still buggy
any core i5 pc Pro already have, can slice on fusion on same machine, could even set laptop up if it worked (power management fun). con bulky 

 Just wondering if I have missed anything or forgot, I did have a look for a guide to begin with but most just say MESA card

Saw a new one today - takshakcam.com/product

Lots of tall promises - but an incredible price if they are telling the truth

"3-axis & 4-axis rotary - Full 3-axis milling plus a single rotary A-axis: indexed 3+1 and simultaneous 4-axis, including a collision-certified geodesic finish." From their website

Removed your last post. You cannot just past images into the post like that you need to use the Attachment box.

I'm not sure what you mean but I'm also not a 5axis expert so somebody else might be able to say more.

Hello, dear forum,My name is Christoph, and I’m thinking about building a small CNC milling machine. I already have a CNC lathe with an Acorn from Centroid that works. Now I’d like to try out LinuxCNC. LinuxCNC is completely new territory for me, and I’m counting on your support. I’d like to implement the control system using EtherCAT. I have a Beckhoff EK1101 and a few input and output terminals. I’ve set up a virtual environment on my computer and followed all the steps in the YouTube video by talla83. Unfortunately, no slaves are being detected. Now I’m not sure how to proceed. Can you help me? Thank you very much in advance for your help.

We expect to release a Five Axis product in Jan 2027. It will be a separate product and we expect to price it at a similar 199 USD on launch and 399 USD after.

We are also aiming to release TakshakTurn by the same timeline and once again it will be a separate product with similar pricing.

Overall, we will never have a subscription model, it will always be a one time purchase.

btw .. our 4 axis strategies beat the crap out of what Fusion offers and we have an equally good 3 axis suite. If you are willing to try it, there is a 30 day money back guarantee.

We don't talk about what is used in industry and why. We are talking about using Ethercat in a machine controlled by LinuxCNC. And here we have factors such as the availability and quality of documentation, sample configurations, or tools, and here Ethercat loses to Mesa. Therefore, I believe that unless there are compelling arguments for Ethercat, it is better to use Mesa. 
"Ethercat is faster" is not a valid argument, because anything that is faster than the required minimum will be sufficient.

hey this looks pretty cool.  i just spend some time going through your videos and website

have been using cam for several years.  started with fusion 360 but got sick of autodesk so went to bobcam with solidworks which is pretty good.

not as easy to use as fusion but more powerfull finishing tool paths.  though i prefer the fusion adaptive tool paths.   Obvously i prefer open source as most linuxcnc people will do so looking at freecad as its getting better.

I find with my normal cam workflow i use adaptive clearing roughing for most stuff and facing cycles etc.  and then some sort of steep shallow type tool paths.  so a combination of parallel and 3d contour

do you think it would be possible to offer anything for 5 axis positional stuff.  i have a large 5axis that i want to try out soon.  and currently no options for cam.  my stuff only does 4 axis.

cheers

Good Morning together!

the switch to r8168 did the trick for me! Communication is running, i can not say how solid, but now i can start LinuxCNC without error, and the green LED keeps flashing. Thanks for your help!

Do you think i should stay on 2.9.10 as i am now , to keep my system running?
Or how often does LinuxCNC change the Kernel during updates?
I'm not keen on holding my breath after every update if the communication is broken..

Greets, Tom

Hey great! I pushed the file changes.
Thank you.

1. I use Mesa for everything.
2. Not sure, but i think those are EXE something or another, and yes, LinuxCNC should work with them, from what i read here.
3. Yes, see Mesa THCAD
4. Guessing, stepper with current control should do, servos should also do, but for more info/ideas look for BAX EDM on youtube.

Todd, would be perfect for that, and he is in USA, IIRC.

Seems like outputs, but, clean the chips and the board so we can see numbers and copper lines.

Not me, despite really needing the money, i never charge for any help here or when initiated from here, and i am of no use for Probe Basic, yet.
For other things related to LinuxCNC, i am here often and daily, so feel free to shoot questions here.

Ah, it sounds pretty obvious once you think about it. Thanks!
