    Upgrade/repairs

    So a customer asked me to repair a diy machine he bought a while back. He has a lot of issues with this machine. Once it arrives at my place i will post photo's, must say i am very excited to fix the machine.
    For now i stripped the old control panel, cleaned the parts. Next i will power up the HY drive and make sure all the parameters are set correctly

    Downloaded the manual for this 2.2Kw drive. Went through the settings....all seem ok. The drive ran my spare 300Hz spindle motor fine. Setup was for manual control so that will change plus a couple of tweaks

    I will document the control panel build here in case someone might find it useful, including the HY drive setup.....cause i see lots of people having issues setting up this drive. The gland plate will be replaced by a 3mm aluminium one so as to serve as a heat sink for the gecko drive.

    Re: Upgrade/repairs

    Here are a couple of pic's of the machine....it's a big mess. How he managed to machine anything on it the way it is is crazy. Not he has only on drive on the Y-axis and it is on the side??? No wonder the axis jammed up. I will strip it down completely soon as he drops it off. As you can see in the pic the drive was installed on the machine open air. This is something i will never do...specially these drives. Also i noticed they used a screened cable from the drive to the spindle motor, great but the cable is definitely not a cable rated for mains voltage.

    Tomorrow the plan is to connect up some steppers to the drive to test all four channels. Also going to set up the speed control of the spindle through mach3....he was manually starting and controlling the speed of the spindle. Bought a heat sink also today...once everything is tested i will mount all in the enclosure. Hope to get the machine soon so i can start the mechanical repairs.

    Re: Upgrade/repairs

    That is an interesting machine and something that looks like it will be very suitable for a rebuild / upgrade. Parts of that machine look to be well put together but then you see a lot of issues that most would consider to be basic machine design errors.

    In any event I think you have a nice little project on your hands. Fix a few things and you will have an excellent platform.

    When i saw the machine that was exactly my thought, a very suitable machine for a few tweaks/upgrades. Main problem is the single axis drive on the one side of the y-axis. Once the other drive is installed it should make a huge difference. Found a lot of play in the ball screw mounts/bearings. Play in the linear bearings on the y-axis....i do expect damage cause he indicated the y axis went massively out of alignment many times. Can't wait to see how a steel frame machine compares to the one i did.

    Well...the gecko is tested, confirmed all four axis working fine. Speed control of FVD working through mach3/gecko....time to start fitting stuff in the new control panel

    Re: Upgrade/repairs

    Hi Ericks - I've got a gecko on my machine with big motors and its mounted to timber. No overheat issues even in our summer. The Gecko is a really solid unit, I tried to kill it a couple of times, worthwhile putting limiting resistors on, made a difference. The unit tripped out too easily otherwise when its running 4 big motors. Cheers Peter

    Re: Upgrade/repairs

    Hi Peter, thanks for the info. You are correct it seems like a well built unit. I understand re the heat but i have a tendency to over engineer things
    The customer did inform me that he never had overheating issues. However i am adding an additional motor and he has enclosed the space around his machine so i'd rather add it.

    Gland plate done, milling this steel plate was no problem. I added additional entries in case he wants to upgrade/add stuff later.
