I am finally making headway on my retrofit. Now as soon as there is a run signal the spindle goes to turning about 20 rpm. no orient signal, no analog speed signal, but it still runs. I have dug...

I still changed the stinky coolant and thoroughly cleaned the machines. The bubblers went in with the new coolant.

I run aquarium air bubblers in my coolant all the time and the stinky coolant problem went away.

Sam,

Do you have an example of what your Classicladder looks like? I have to finish an interface board for my machine then will be onto the tool changer.

You should be able to as long as you can get a 0-10VDC analog signal to the servopack. I have CACR-SR10BB1BF drives in my Hurco driven with Pico Systems PPMC on Linux CNC.

I would imagine one of...

Nice! I'll be working on my Hurco retrofit more this weekend. I'm to the point where I'll be on the tool changer very soon. My tool changer looks like it's very similar to mine in the process.

I like that GUI a lot! Your custom creation?

My buddy had to rebuild the pump on his Flow 60k and it was like $15k to rebuild the pump, new intensifier pump skid was over $30k.

I have seen some small like 4x4 work spaces. But there still $50k it's the pump and support gear that cost so dang much.

Well I'm still battling some servo challenges. If I continue to have challenges I want to upgrade to servo amps. I have had thoughts of upgrading both the servos and servo amps going with the...

Well I broke one last night. Do any of y'all have a source on finding a Renbrandt 617 0.375" on both sides encoder coupling? Or an equivalent part?

Thanks!

I am having servo pack challenges right now. But other than that it has gone well. I'm working 80 hours a week right now so I have not really had time. I'll be back on it in a couple weeks.

Thanks JT!

PM me your email and I'll send it to the webmaster.

I sent a message to one of the Mods with a link to this thread he may be able to get it over to the right people.

Email the web master, I can send them a message if you can't get through.

Have any of y'all done this?

It's looking like I have three drives with issues. I am having a hard time accepting repairing these with the obsolescence issues. I have one drive with a bad IGBT...

I pulled all three drives out of the machine today. I have one with a shorted output transistor on one phase. The other two pass the output transistor test.

The drive that is not going into alarm...

Well when you drain the cooler almost 5 gallons comes out.

Well I'm a retard. Helps when you get the servo power 3 phase contactor closed.

Now I have the x and z in overload alarm #1 so I'll troubleshoot that tomorrow. It's nice that the manual...

I think I can I'll check in the morning

They are CACR-SRCA I have not seen any e stop on the schematics that I have. I have 12 wires connected to the #1 connector and there all accounted for. I'm stumped. Moving the servo alarm over...

I tried to start up my Hurco BMC30 after the Linux CNC retrofit and my servopacks are in a baseblocked condition.

Actually my machine is a BMC30....

I have made some significant headway on the machine.

HURCO BMC30 Ultimax 3 CNC control system

I have the complete Ultimax 3 control system off a 1992 BMC30, I did a retrofit and do not need any of it anymore. It appears that it lost its parameters,...

I have a 92 BMC 30 and want to change the spindle oil. How much does it take with the cooler? I have a 5 gallon bucket on the way. I'm hoping that's enough. My retrofit is getting closer!

I am starting my retrofit!!!

Hurco BMC20 with tool changer

I am going LinuxCNC and Pico Systems PPMC hardware, I have a Dell desktop that I am going to use for it. I just need to get a SSHD...

12x12x6 is probably not big enough to have that drive inside it unless you have forced cooling. The drive manual has a section in it covering minimum cabinet sizes for installation.

Your Lagun retrofit sounds just about like my Hurco retrofit will be.

I am attempting to learn about it also, especially since I think I am going to pickup a Hurco that will need a retrofit. Andy over at .org has helped me quite a bit but I still have...

Cool I'll check them out! I still need to do some design work to verify sizing. Rough idea is two NEMA 34 driving the plasma/router bridge and one driving the head. Just need servos, and power...
