  1. Poll: Re: Four Different Ballnut Preload Designs - Which Would You Choose?

    In designs 1-3 the 5mm adjustment increment could easily be changing using shims under the ballnut flange.
  2. Re: Dear laser experts/noobs/and all who want to help me build a 10 foot by 30 Gantry

    Check your facts boss...

    Synrad does not recommend vertical mounting. I didn't say it won't work. "The recommended mounting orientation for Series 48 lasers is horizontal. If this cannot be...
  3. Re: thread milling advice needed - tolerances

    You need to check something like the machinery's handbook for allowable sizes on major/minor/pitch diameters for certain classes of thread. Without expensive measuring tools and gauges, one would...
  4. Re: Dear laser experts/noobs/and all who want to help me build a 10 foot by 30 Gantry

    A few comments:

    1. The tube should not be mounted vertically. Over time, tiny dust and debris from inside the tube can collect on the output window in the tube. This debris will be burnt by the...

    Re: Hyd pump randomly cuts out

    Doesn't sound like a broken wire, that would make it not restart even if you restart the control. I think it may be a thermal overload relay trip which is cutting power to motor and then resetting...

    Sticky: Re: 18x18 Linear Rail Tormach Build.

    You are killing me!

    The safety charge pump is HARDWARE. It gets a constant pulse train from the computer telling it that everything is ok. If it doesn't get that signal or stops getting it, it...
  7. Re: Please tell me everything i can do better on this vacuum fixture!

    If your o-ring is too stout, your part may not sit very solid on your fixture, basically allowing it to roll around on the o-ring. Also, the only thing holding your part in place is friction. It...

    I think the PIC controls the safety charge pump, maybe nothing else? Did you try to turn off the charge pump (move the little jumper by the PIC12)?

    Sticky: Re: 18x18 Linear Rail Tormach Build.

    The PIC12 is a microcontroller. It has to be programmed for it to work. You can't just buy a new one and plug it in, there is no code on the microcontroller for it to run. All the others are discrete...

    Get yourself a lamp timer, it will automatically shut off your coolant (or anything else) for you. A trip to any local hardware store should get you one. Much better than babysitting all day long......
  11. Re: General question on tool diameter compensation

    The norm would be to program it with the nominal size of the endmill. You would then run a test part (or just a test block if a complex part), then adjust your tool radius/diameter on the control...

    Re: Filament winding Gcode

    The code you have posted can't be condensed to one line because the C axis movement is not linear. If every line was C60, then you could condense it all down to one line with the total Z, C, and X...

    Re: Filament winding Gcode

    I have no experience with Planet CNC so I can't offer specific help.

    It sounds like you need to set a work offset (G54 for example). That determines where the part zero is with respect to the...

    Re: Air Consumption on older Haas?

    A lot of air solenoids are designed so that the electrical solenoid only switches a very small amount of air and then that small amount of air actually moves the valve (by a piston or diaphragm)....

    Re: SURFACE PROBLEM WITH END MILL

    First step is to make sure your spindle is PERFECTLY perpendicular to your table. This process is called "tramming". Google "how to tram a mill" or similar. This is critical.

    That sounds logical to me. I am but an ME as well. :D




    The SuperPID provides some form of closed loop, a rudimetary servo drive, which should allow better performance within the limitations...

    Yes, you can do that. You just need to change your steps per unit and associated settings.

    Re: Bosch 1617 2.25 HP Max Torque?

    I'm going to agree with Alan here. A router has a peak power of XX HP, it is NOT constant over the RPM range and will be very low at low speeds. It is not possible to get 2.25HP of POWER out of a...

    Re: Laser Cutter source code

    OK, I see what you are talking about. The beam has to be defocused so you can heat up the plastic without burning or cutting it. Perhaps you can lie to your machine and tell it you are using a...
  24. Re: what am i doing wrong? - Trying to make a cylinder into sheet metal and flatten i

    I can't look at your model right now but is your cylinder continuous? If so, that is likely the problem. Your cylinder has to have a break somewhere so that it can be flattened. I'd draw a circle...

    I run a Kern laser with Coreldraw and you can either cut vectors or engrave images depending on how you set it up in Corel.

  26. Re: Arc welder as cnc power supply for Series 1? Anyone try it?

    A welder is going to give you noisy power with a large ripple voltage.

    Why not just buy a simple single phase supply and be done with it?

    I think this would do just fine: PS-15N70 - 1500W 70V...
  27. Re: just bought $500 chinese/taiwanese TSK160 tilting rotary table!!

    I don't think plasma cutting big dirty pipes needs the accuracy or rigidity of a harmonic drive. I'd probably suggest a timing belt drive with a big pulley on the spindle giving you a big through...
  28. Re: BP Series 1, 2HP Rigid Ram. RPM max only 2600. Otherwise perfect. ???

    Sounds like the vari-drive belt is worn.

    If the belt is narrower than it should be (from wear) it will not reach the very outside of the spindle side pulley and will therefore not achieve max...
