    China Freight has a truck bed crane for $120. You can bolt it to the bed and lift the motor and gearbox off with that.

    Maybe narrow the problem by disabling the X and Y axis and see if the Z zeroes. If still an alarm then disconnect the X and Y cables. Then try each other axis alone.

    If you are cutting on the perifery or where there is simultaneous rotation and XYZ motion remember to put the diameter (or radius) of the part in the settings. Otherwise the machine cannot keep them...

    Did you change the file back to a .nc extension? I doubt your control recognizes a .txt file.

    In series there will be less pressure drop across both which will increase flow.
    In parallel it will need one way check valves on both to keep the stronger pump from backflowing the weaker pump....

    Yes, BT40. The carrusel forks are different than cat40 and all the tool holders that I have are BT40.
    I could use inch sizes, 1/8" to 3/4", ER16 and ER32.

    If you still have the needle thrust bearings it is worthwhile to replace them with the double angular contact setup of the later machines. On my '91 the needle desintegrated and the cage was wearing...

    Maybe try bluing the taper to see if it matches the spindle taper. If it does then I would suspect the Belleville spring stack.

    The upper RS-32 port is for I/O. The lower is for the 5th axis. One goes to J13 on the video board, the other 850 on the processor board.
    Check the SIO and MSG LEDs on the processor board. Both...

    Even the old black Haas 5C go for quite a lot.
    I built a 4th axis using an 8" Enco rotary. I got a motor that worked with the VF-1 servo supply (160 VDC), added an encoder (Agilent has nice ones...

    I have not had a problem with mine but you could use the old fashioned method used in the pre-dawn era of reprogrammable chips, loop a piece of thread through the socket pins and around the chip.

    I just touch off each tool by rolling a 1/2" pin between the tool and part then hit tool set. G54 Z has -0.500. Rather difficult to touch off a tool directly to the part without mashing into it.

    I did not have to disconnect the battery when I added the memory. Mine uses the HM62256LP-10 chips. You can check the power supply on yours with a meter on pins 14 (lower right) and 28 (upper left)....

    The A axis card is lower current capacity than the X/Y/Z cards which is probably why it went out.
    Typically the output transistors and possibly the drive transistors go. They kept increasing the...
