Retrofit of Precix 5x10 CNC

Thanks Todd, I will get those drives out and get some good photographs. I'd love to get the 7I92M +7I77 combo and be in business with LinuxCNC!

Thanks bevins, I will shoot them a message!

I like your idea about the replacement of the motors too. If I went with those I would need the 7i77? or the step/dir controller?

Ya, they put everything in that box... computer/cpuPSU/drivePSU/drives... pretty crowded. So I am going to take cpu stuff out and then just have a stand alone computer. Ethernet wire or db25 connecting them. Should give it some space.

Yes, I use 5i25 7i77 withthe servos. You can use ethernet if you choose though.

Becins, Did you order those motors from China?

Only problem I have is that I am incredibly impatient. Is there a US source?
Actually got a couple projects that I would like to use CNC for, but are way past due. I am working on figuring things out, but I would love to get this machine up and running soon.

Thanks for any input!

Had them in a 2 weeks. I just bought 7 from them and got them for 165.00 each servo/motor/cables.

Check and see if your Z axis motor has a brake though. You can get the servos with a 24VDC brake.

Thanks Bevins,

I think I am going to order the 7i77 and then if the drives/motors aren't compatible, I will probably buy some motors like you suggested, i'd still prefer a USA source, just to my impatience.

Yes, I believe the Z has an elecric brake, so will have to find that one.

only reason for not going with 7i77 is I went with steppers, right? and I will probably stay with servos.

Thanks everyone!

I still gotta get part number, but the cnc is located in a place I don't have tools... so now I gotta get some tools there to start checking it out. Thanks

Finally had an opportunity to be able to disassemble the machine to see the model numbers of the motors.

Here is the Y motor:


Here is the X motor:



Here is the Z motor:




Drives coming up nest...

Here is what I could see as far as the driver boards for the XYZ axis.

So my question now is, should I try to use these driver boards or should I change them up? Should I try to use these motors or change them up. If one of these motors dies (or is already dead afaik) would it be easy to find a replacement to use with this setup?

I couldn't seem to find an exact match for these motors online, so I would have to find a compatible motor. I guess what I am saying is, it would be nice to be able to order a replacement piece (motor/driver/controller) without having to change out anything else in the future.

PCW, do you think the 7I92 + 7i77 setup will work with this equipment?

Thanks for all the help thus far and thanks in advance for any info, I really appreciate this community for helping me get this machine up and running!

OK , those are standard analog drives as suspected, so a 7I77 should work fine
I would test the motors before making any judgements

(disconnect motors from drives and linear axis and apply say 5V to the MOTOR+ and MOTOR- leads)

Thanks PCW!

I will get those items ordered ASAP.

I see there is a sourcing and a sinking option, which would you recommend?
The 7i77 should have no problem with my VFD, correct?

Thanks,
Randy

I ordered the sourcing version. Seems like that was more common? Is it just a wiring change to go from sourcing/sinking? I hope I ordered that correctly.

Thank PCW
