It runs at 55,000 psi maximum pressure.
My company is an distributor for KMT pump in Thailand.
Their pumps are reliable.

So finally, my CNC Waterjet machine is completed.
It has all connected to the pump and get the High Pressure Jet on.
Thanks for everybody support. I love your Acorn Controller. It's such and incredible borad.

hello. post a fresh report.zip and the g code program that you are running for us to see the tool library and the g code program (what tool it is calling)
this also allows us to run our system exactly the way yours is configured.. without this information everything is just guessing.


So sorry ...

I've tested the same drawing today and the Line just show up without changing any setup.
All other drawing also no problem.
May be, it's just need to re-power on the Acorn after upgrade (which i did re-power 2 times yesterday).

Actually, I haven't set any tools in tool library since 4.18, because ...

I set the tool diameter very small at 0.2 mm because I runs this code for Waterjet cutting. By the way, it was exactly the same g-code I run on 4.18 and 4.20, but the line is just disappeared after upgrade. So, I wonder why this problem happened.

More information, I’ve tried to press “Trail On” (F9 ...

However, i found that the Follow Through Line (Yellow Dot) that usually follow the spindle for real time moving is not appeared after updated to 4.20.

Where should I set up to make this Yellow Dot come ...

Interesting project... What are you using for the water jet?


I've got inquiry from some food customers to cut cake, ice-cream, and vegetable.
These applications just need pure waterjet cutting (usually other hard material need abrasive waterjet).
I have demo unit of abrasive waterjet that ...

As long as your drives total required signal current do not exceed the DB25's output (vary unlikely) there will be no difference


Thanks for your comment. If there is no any difference, i'll just leave it hardware axis pairing like this.
I didn't connect through DB25. The connection signal is ...

I've just finished assembly a 1000x1000 mm Workbee CNC for my Waterjet project with Acorn.
This is my first project to build, so i just try it with Workbee hardware which is cheap (2.45 N.m Stepper Motor, TB6600 Driver, 8mm Lead Screw).

I've paired the Y Master and Slave Axis by Hardware pairing ...
