I have a Supermax YCM-30 milling machine. I did a control conversion 10 years ago to linuxcnc. I used the old Servo Dynamics motors and amps because they were working well enough. Over the last few...

Thanks!
My doesn't look quite like the picture. The unit in my chassis has space for three fuses. Only one is populated and the fuse isn't blown. I'll try cleaning the tach brushes.

I have a Yeong Chin Supermax (Bridgeport clone) circa 1989. It has servo dynamics motors and amps ( SDF-1525-12).

Lately the X axis VOL LED is tripping frequently. Otherwise the axis is running...

I have a manual lathe in my show with a D1-5 Camlock spindle nose. I have several chucks including a collet chuck and a three-jaw that are set up with the D1-5 backplates.

I also have a...

The VFD was powered on but not running when the outage occurred.

This is single phase supply. 220 wired into the mill cabinet and enabled through relay so it turns on with the rest of the mill.

I have a Huanyang HY02D223B on my milling machine.
We had a power outage today and now I have no power to the mill spindle and the display reads EEP. Pressing the reset button flashes the F00.00...

My problem started up again. Motor running rough, especially on startup. The previous fix (cleaning brushes on the tach side) made such a difference I decided to repeat the process.
This time I...

I think you nailed it! I pulled brushes and put a shop vac on one side with a filter. I pulled out a shaving the size of a fingernail clipping. Motor running smooth so far. Thank you!

A bit more playing around yielded another clue. If I run the motor fast in one direction for a while, it gets smoother. Stop and restart and it's rough again.

In case some weary traveler should find himself at this lonesome spot one day, I leave this token of my time here.

Thanks John, I think the optocoupler is this one: https://www.broadcom.com/products/optocouplers/industrial-plastic/digital-optocouplers/1mbd/hcpl-2531

I have a couple microstep drivers that I acquired surplus. model numbers 31234 and 30737. They look like very step drivers from leadshine and others and the silkscreen on the case is identical but...

I'm working on the CAM workbench (Path) for the open source software FreeCAD . Path is still pretty young but able to do some interesting 2.5D work already.
Anyway, I'm interested in writing a...

I'm working with a startup venture building a new kind of manufacturing network. We've been demonstrating our system to selected user groups and getting strong demand for the kind of service we will...

Scorch,
V1.20 looks great and fixed the problem I was having a couple months ago. Thanks.
One feature I'd really like to see is a simple way to use the app from the command line. I'd like to be...

Was there ever a resolution to this? I'm seeing the same error on the new (13.04) Ubuntu.

Mine turned out to be a ground problem - poor connection to ACM. Runs great when wired correctly.

After trying about thousand things, I convinced myself the issue wasn't mechanical and went through the amp tuning again. I adjusted the CMP up a little and the axis movement smoothed out...

I have a YCM-30 milling machine with SDR 1525-12 amps and servo dynamics motors. It's been running well but recently developed a problem with the Y axis.

On long jogs at about 50 IPM, the amp...

I have a new Huanyang VFD (model HY02D223B) connected to the spindle motor on my retrofit milling machine.

I'm trying to control the speed with the analog Voltage pin from LinuxCNC with a mesa...

The title says it all.

I'm retrofitting a ycm-30 to run with linuxcnc and I'm searching for documentation on the original wiring.

I recently bought a used mill and got three of these motors and a mechatronics card in a box of stuff that came with it. I know the mechatronics card isn't very good but the motors like nice. ...

It looks like I'm hitting the same problem. Any additional details you can provide would be appreciated so I don't have to reinvent this. Much thanks.
