Re: LinuxCNC homing grief

I replaced the Z axis switch and all is well again. I believe the old switch had fatigued and wouldn't spring back quick enough again after being hit once during the homing step.

So our Nebula is back in service, at least until the next time a limit switch fails to do its work.

LinuxCNC homing grief

Today I can't get our Nebula to home. The first time when Home Machine was clicked on the z axis moved up, came to a stop and generated this error message: "Can't unhome while moving, Z-axis". Clearing that error, then reconnecting to the controller the Z-axis moves down rather than up whe...

Re: Computer locking up/crashing on my Asteroid

Sounds like you found an EM interference frequency (#4 on your router) that confuses the PC. Any chance you have a WiFi or Bluetooth dongle plugged into the PC , or even wireless mouse or keyboard? I know my old microwave will generate WiFi interference in my house when it runs. I've never had my CN...

Re: Am i Racked or Frame out of square

It is more likely that the plastic drive nut(s) have stripped. See if you can manually push the gantry forward and back on either side. If so then you need a new anti-backlash drive nut or two. http://www.probotix.com/CNC-CONTROL-SYSTEMS/MECHANICAL-COMPONENTS You might also check that the Y axis lim...

Re: Rosettes

When you get done with the t-rex, there is always the u-rex, v-rex, and w-rex you can make. The delightful part of being able to make dinosaurs on your CNC is that you aren't limited to making versions of just those know beasts. Invent your own. ;) Name them after your grandsons.

Re: Rosettes

Looks great! Now the question is.... for the time spent drawing it up, and the time spent cutting them out on the CNC, are you still under the cost of a rosette cutter? ;)

Re: Hello from Las Cruces, NM

Hi Ed, and welcome to this forum. My Meteor had the older controller, and one day it simply quit working unexpectedly. Len at Probotix sent me a new Unity controller in exchange for my old one after I'd verified that something internal had failed which I couldn't fix. He mentioned that series of con...

Re: CHURCH PEW

Great job! The round corners of the original cut out pattern almost make me think it was also done on a CNC, or at least with a template and a hand held router. Perhaps years after the the pews were originally made. Not sure how long ago hand held routers came to be. I'm guessing none were available...

Re: Lines in Finish Project

When a lot of material is removed (by a roughing pass) I've seen boards bow upward as fresh moisture reaches the newly exposed wood. Knowing that could happen I typically set my allowance to 1/8" or even more just to make sure none of the roughing cuts are left after doing the finish pass. If t...
