    Ok so after going through the parameters and setting everything up and making one changer to the torque saturation setting from 450 to 550, it seems the bogging is gone. Here is a test video of the same doc, woc, feed and RPM..

    Tool - 1/2" 3 flute carbide endmill

    WOC - 2.5mm(.0985")
    DOC - 17mm(.6692")
    RPM - 6000
    IPT - 0.0056"
    IPM - 100

    It's not synchronous according to that data sheet. I would look into the slip settings as well, that data sheet actually has the info to calculate slip. At 50 Hz, unloaded a 4-pole motor will run at 1500 Hz. Slip is just 1500 - the rated speed. So should be somewhere between 34 and 48 if it's similar to those motors. I'd try changing the torque saturation back and try putting in a value of 30 or so for slip and work up from there.

    Ok, here is a short video of today's testing of the spindle power. As you can see some of the power is bumped back up but it still bogs in heavier Cuts now which may just be the power curve of the motor. We have a few settings left to change and we benchmark..

    0.011" per tooth? That's not messing around Looks like fun!

    for sure!!.. that is a healthy cut for certain, wouldn't hurt to have some more power in the spindle.. considering upgrading the spindle and spindle motor, from 5.5kw to 7.5kw and bumping the speed range up yo 12k rpm and new spindle to handle it. at the time of originally purchase the funds were not available for that upgrade, but maybe in a few months they will be. seeing as we process 90% aluminum it makes a lot of sense.

    Great Thread ! Thanks for all the documentation ... very insightful. Hope you get this Linux CNC thing all sorted as well as much success with your new baby.

    All that said .. bro - I need these connectors in my life ... where can I find these ?

    They look like GX16 connectors

    The connector appears to be a GX 25-4

    Did you ever get a chance to check the runout on the BT30 tool hoolders you got from tool tree? I am looking at ordering a set of BT40.

    Chris,

    I read this entire thread..great job. I'm still not clear on the status of your machine though, is it finished and running? The videos appear to be the other fellows machine..correct. Did I miss something, I know you were a bit stymied on your control system, did you get that sorted out?

    Thanks,
    Stuart

    Stuart,

    My machine moves around but not finished with the CNC control yet. While I pulled the shop apart for running the wiring and phase converter connections for this machine I have taken the opportunity to run wiring for various other machines around the shop for future upgrades, run a full shop airline system 300 feet with 9 spigots, and add new shelving and organization through out the entire shop. I have a small business that is run by myself so it takes a majority of my time keeping up with that. I also in the interim run my grizzly for making my parts which gets the job done albeit a bit slower than the new machine should be able to do with less intervention. Once everything is wrapped up with the rest of the shop updates which were a matter of convenience during the big machine wiring and pulling the shop apart for wall access, I will return to the control wiring which should not take to much time as I now have everything needed and a finished schematic I built for all the control wire runs!

    I will post up some pictures of the shop once it's completed, I'm pleased to say its really taking shape nicely and was a long time coming. I had originally needed to move out of my commercial building into my home shop rather quickly and also out of the apartment we were renting into the house I built, so I didn't get to do some of the things I wanted back then. Now that I had that opportunity it was a no brainer to go ahead and Debbie the time and money to it!

    Chris

    Also very interested in how this turns out.
    Looking hard at a few different China machines.

    I'm back working on it pretty steady right now I've got the front panel all finished and steady working on the back cabinet wiring in the evenings. I made a few changes along the way to a mesa 7i92m/7i76/7i77 combination, I haven't gotten any of that setup yet but here are a few update pictures of the front interface..

    Ok, so I've completed the working schematic for the most part with the combination of the 7i76 and 7i77 boards now and have set up my wiring station at the back of the machine. I sent of the PDF to be printed on large format paper to hang up while working to make sure wire runs are easy to follow and double check . Also so in a few weeks/months/years when I've forgotten it all I have a good reference to fall back on..lol

    New drive cables should arrive tomorrow, took the weekend to work on the flood coolant system.. Did a few upgrades to the sick single line that came on it. Upgraded the hose to 3/4" ID, added a 20 micron filter system with inked and outlet pressure gauges, thanks to NYCCNC for his video on it and BOM from mcmaster.. I upped the filter housing size to the 20 inch to reduce the pressure drop he was seeing hopefully and will report my finding on that once everything is up and running.

    Ordered a distribution manifold from mcmaster but it won't arrive until this Wednesday, it will have 4 outlets for 1/4" locline valves and hoses. Sould be enough flood coolant for now I'm hoping.

    Here are the progress pictures while waiting for the final drive cables to arrive and finish the last of the wiring!

    Thanks!

    Chris

    ok quick update!! wiring is complete!! who hoo!! I am just getting my feet wet in linuxcnc, I have with the help of some really great people of the linuxcnc forum and IRC skunkworks, PCW, TomL been successful in fixing my wireless lan and setting up the static IP for the 7i92 card and have flashed the new firmware for the configuration I'm running. now to build a config file for the 5i25 and convert it to a 7i92 config file and see of I can get this thing moving around!! getting closer!!
