I recommend using an old toothbrush to clean the router collet - better than compressed air or simple tapping to the collet. And you should also check the thread of the spindle if it is clean.
Wonderful information, collett dust can be an issue. Thank you for sharing this with us today, Stay safe and healthy, from Henrico County Virginia
You got it! Thanks for the support
Thanks, all good ideas. One you missed is checking the fasteners on the CNC. Today I saw a very small set screw on the table and thought “that must be important”. Well, it was one of two that secure the toothed pulley to the Y Axis syncro motor. Before I realized what the screw was for the machine lost orientation and was milling about 6 inches from where it was supposed to be. Two Y axis motors and all set screws were loose… Live and learn… also, I used fixed guides on my bed but I don’t align them with a square, I just travel the CNC with the spindle running, perfect alignment…
Thank you for the information. I am new to CNC and one of the other commentators (@Wolfram Herzog) mentioned using an old toothbrush to clean the dust out of the collet. I use it to clean the collet and the bit. I use an auto-touch plate and that little bit of dust can cause the auto-touch plate to not make a clean connection and messes up the calculation.
Thanks for sharing!
This is really helpful Andy, thanks for sharing. Running an Air Pass is also my favorite! There are times I will make a toolpath specific for Air Pass purposes so I can verify all geometry of my toolpaths will be clear of my work holding.
Great to hear, Cory! The air pass is my favorite as well.
Nice Job Andy!
Thanks, Tony! Hope it was helpful
Andy, What is your favorite side work holding on the shapeoko pro
Limit switches for a fixed home position.
Not sure I'd tap my collet nut with a wrench, rather quickly unscrew, tap on the MDF bed, better to blow plus always have 2-3 brushes by machine inc tooth brush - soft paint brush.
Thank you for your comment. Can you explain the limit switch for a fixed home position a little more?
I do unscrew my collet from time to time but lightly taping my collet nut has worked well in between those times. I started doing it a few years ago and haven't had any issues.
@@AndyBirdBuilds On the collet, mine took a little damage just from losening and tightening, hence not keen on intential tapping, just my own experience.
Re limit switch, just fitted them to mine today due to some repeat part jobs that are harder to index any other way.
Once limit switches are fitted, they both stop the machine running off a gantry or out of bounds, however you can also use them to have a configured, hard wired home position, at least in MACH. On starting up the machine, you hit 'ref all home' and the machine goes through a homing sequence. If you ever lose steps part way through a job, you can reset home accurately (and any offset controlled from there via DRO). A lot better than a mark on the workpiece.
@CNC West Cumbria Okay cool. Thanks for sharing. I'll be diving into Mach here very soon and I can see how this would be helpful!
@@AndyBirdBuilds When you consider most incidents are human error somewhere along the way, it's anoither way to reduce it.
Just don't use the tiny, cheap limit switches I did, they still work but they're an absolute pain to fit.
Andy, thanks for the info. Can you tell me what software that you are using.
Thanks, Mike
