Shopgeek,

This is tough without physically loading these into a Haas control. These values are the equivalent of Greek to most of us. My two recommendations would be to replace the floppy drive...

The shift piston may be boogered up, the solenoid could be bad, but most of the time it is caused by the gears wearing into each other, preventing proper shifting. If this is the case you are usually...

If you go to EDIT, press F1 for "floppy DIR", what do you see? If nothing, you may have installed the ribbon cable upside down. Ask me how I know.... :-)

GITRDUN,

I recommend replacing all 5 axis flow restrictors on the X axis and the Y axis (10 total) part number 58-4000. These are about $7ea and clog up easily. While you are at it e-stop the...

I'm not a fan of the Haas 30k machines. They go through spindle belts and the drawbar will go bad long before the the spindle does, but the drawbar is "non-replaceable" so it requires rebuilding or...

Al,

That is very interesting, but I have not had any problems in the field. Have you seen any problems associated with this?

Thank you,

Speed,

I recommend using a megger and checking the motor resistance leg to ground (disconnect from the amp first!). If it's under 1meg ohm then you have a problem.

Thank you,

Me neither, that must be custom. Has the machine ran in the past with this drive? If you think it's the drive that is bad PM me and I'll set you up with the right people to rebuild your spindle...

What's your 12+/12-/5vdc to the processor stack? Locked up control can be caused by the low voltage power supply or the processor.

Thank you,

thewho,

Thanks for the quick reply. Would you be able to tell us how accurate your machine is (squareness, backlash, best tolerances held, circular interpolation, spindle tram etc..)? I watched...

Leix_99,

Great build, just read it today. Do you have anymore updates? I would like to know more about your Epoxy Granite recipe if possible.

Thank you,

Phil

thewho,

Time to see some new progress!

Would you be able to give us an estimate of what you have into ($) building this? Many of us really like your work and want to know if something like...

Spartan,

I don't think that is too big of a deal. Check the bearing surface for corrosion.

Thank you,

Phil

Claudiu220405,

Did you check the concentricity? Make sure the spindle probe stylus is centered relative to spindle rotation. Get this as close as you can, it might solve your issue. I have talked...

JasonR,

Make sure the cable isn't upside down...

Totok,

This could be caused by the shuttle motor, motor clutch, tool changer relay or I/O board. Give us more info please.

Thank you,

Phil

The drive motor coupling will come off with heat and a 20 ton hydraulic press. Make sure you measure the depth of the coupling before pressing it off.

Do you have a Yaskawa motor or a Haas motor?...

Daleman,

This is a very common repair to replace the motor shaft encoder pulley on top of the spindle motor.

Do you have a steel or an aluminum pulley?

Do you TSC (through spindle coolant)?...

See if you can figure out a way to have easily changeable tools. Most machine tools use a tapered spindle that can accept tapered tool holders. Use an air cylinder to open the drawbar that hold the...

Hello,

I am looking to buy any smart Haas vector drives in any condition as long as they have not started on fire. Let me know what you have, PM with pics.

Thank you,

Precision MT

If your machine uses the old gold anodized non-smart servo amps the aftermarket units from Sequoia work very well and come with a 2 year warranty. Factory parts only come with a 90 warranty if the...

Dresnerm,

+12/-12 should be 11.85-12.5vdc, 5 should be 5.0-5.25. I usually see issues start when the LVPS drops below 11.5/4.9vdc.

Good luck,

Phil

Dr Evil,

Haas does things a little differently from most machine tool manufacturers, they sell the whole spindle and you send your old spindle back to the factory to be rebuilt. Haas will not sell...

Dresnerm,

Be careful if you do find someone with a 98 machine, the parameters will be different with every option. I doubt you have this, but do you have the original paperwork that came with the...

M_D,

On the IO board to the right of the plug for the conveyor there is a 4 wire plug that is your 230VAC 3PH input to the IO that powers your auger. If you have power at this plug but no power to...

Microns,

What are your Z backlash (parameter 41) and Z friction comp (parameter 140) parameters set to? I would run a ballbar test, make sure if you do that the tech runs the Z axis! Most take the...

Let me know if you find anything, finding Haas parts from their manufacturer can be tricky. It would definitely increase your resale though.

I buy and sell used CNC equipment, PM me if you are...

Good info! I'm going to remember this one.

Thanks,

Phil

Check all voltages, especially the low volt power supply. It sounds like a bad processor, but it's hard to diagnose without standing in front of it. Let us know what you find.

Thanks,

Phil

Good info guys, thank you both!
