    I run my spindle at about 4K rpm max , so our temperatures are similar.

    I think I understand what your description of the "wobble". I am not an expert but I do not remember my bearing having this....

    The comment about belt tention is a good one, it should be investigated


    ....what is the part number for the bearings, do you have a link to the technical specifications.

  6. Re: New angular bearings on my X2 made the spidle stiffer.. How to overcome it?

    I do not have a definitive answer for you but can share my experience.

    Re: Wierd Anomaly with Post to Mach3

    Mach3 has settings that deal with circles. Those settings have to coordinate with similar parameters in the post processor. I can't tell you how to alter the post precessor, i haven't figured it out,...
  8. Troubleshooting lost steps: Pulse width, Dir LowActive

  9. Re: The cutest face mill ever (ISO10 spindle and tool prototyping)

    Lomax: These two items look like they are for wood routers. Usually that means that the bearings are not robust enough for milling. The exception would be very light milling in aluminium or very...
  10. Re: Help understanding Work offsets and Program limits

    Kenny. I did multiple regens, file loads, restarts.

    While having G54 offset being the current offset I always get a dashed line from my toolpaths going to the machine home. Is that normal?
  11. Help understanding Work offsets and Program limits

    I have a question about the Program Limits window in the Toolpath Screen.
    It is when I use a work offset ( the x,y zeros for G54 are not the machine home).

    So my code only refers to locations...

    Re: Newbie problem-wiring in spindle motor

    I don't know enough to answer your question. But until you get a proper answer, go to the manufacturer of each component of your machine and download and save each spec sheet, user manual, etc.

  14. Re: Help in interpreting results of Rollie's Dad method for aligning spindle on my Mi

    I am not familiar with this method of testing, so I am only interpreting your results.

    Re: PM-30MV with BT30 Spindle?

    As far as spindle power goes, it depends on what you will be cutting, although more power is always nice, more weight on the head isn't. Especially with your spindle adapter idea.
    Your plan to...
  18. Re: G540 to Consew Type Servo Sewing Machine Motor

    Ron Thompson: could you post a higher resolution file of the schematic ? The version you posted is very hard to read and the Yahoo group has been cancelled.

    I have an old knee mill, made from castings.
    It is table top, so about half or 2/3 the size of the commonly known Sieg X2.

    It will be used for manual milling only, no CNC.
    It is fairly accurate...
