Just got it powered up at a friend's shop... 24,000 rpm is pretty scary.

Redstar99 is currently working on the video of the clamp being cut... Unfortunately it will only be part of the machining cycle, as the phone/camera crapped out, yet again

I will be shooting some video later tonight of the finished product, assuming all goes well.

I have to install the main power tap/breaker, and then upgrade the controller software to 2.5.2 from 2.4.6... and finally I have to integrate the Huanyang library into LinuxCNC.

So... A small update while I am stuck at work for the next 12 hours

The spindle is installed, and tested in manual mode. The integration of the software was a *MAJOR* PITA. If anyone decides to attempt to use a Huanyang VFD withe LinuxCNC, please contact me. I know *WAY MORE* than I ever wanted to about this installation.

And for the bad news... I was up until about 7 am trying to get the serial port to talk to the RS232 to RS485 converter, which allows LinuxCNC to control the VFD... No luck so far. I plan to sneak out of work in a couple of hours to hit Baynesville Electronics, right across the street, to try to acquire a serial port tester, so I can figure out where the breakdown in communications is.

Yes, I am double posting

I have acquired the resistor, LED and db9 female to build a loopback/LED serial port blinker so I can determine which port is which on the back of my controller computer.

I have been looking into what modifications I will need to do to get better performance from it, too. It seems you can set the affinity of the real time extension in Ubuntu/LinuxCNC through the GRUB2 but I am not home so I can't try it out.

At some point I am going to have to go looking for a 802.11? card that Linux/Ubuntu has drivers for, so I can allow the machine on the internet :gasp:

More early tomorrow morning, as I still have 7 more hours in this shift :/

The new controller has solved all the problems with communications to the VFD. Now the issue is getting the commanded speed to match the actual rpm of the spindle.

Since I'm going to control the MAXNC10 with a router speed controller (mod already done and tested) I am looking at a tachometer of some sort so I can read and adjust RPM. Maybe you can use one to baseline your machine and apply a multiple to account for any variance in what the controller thinks and what is actual.

I now have spindle speed control, and a much more reliable LinuxCNC controller.

I added a light to the spindle.

The circles were set to be machined at 40 ipm but I was also traversing the Z axis, so it my have been limited... I wasn't paying attention.

Oh... and I added a WiFi connection, so I can keep the OS up to date

Actually, the next two shop projects are to remove all the extraneous crap from under the milling bench and mount the air compressor and the shopvac so I can have coolant and chip removal.

I will get to it sometime this lifetime
