CNC Router, Kudos, Old News and Current Status
Kudos
Thank you Randy for staying late and helping with the bed rail leveling
Steve, Thank you for picking up the needed hardware for the upgrade/refurbish. Oh by the way We could use a couple of sheets of MDF 3/4 “ x 2’ x 4’ for the apron, fences and cam locks
Sal, Thanks for lending a hand with clamping the dial indicator to the z carriage.
Dave, Randy, Hugh and Steve, Thanks for great brain storming regarding the use of the front edge of the Router. Everyone is going to love this.
Old News
About two months ago I shimmed the Y axis rails to tighten up the rollers to eliminate the rocking in the gantry. Also shimmed the X axis rail to tighten up the router carriage. It improved it but still needs some work
Current Status
Current Issue As Found As Adjusted Status
Base Square Corner to Corner out by 1” Within .020” Done
Table Rails Not Co-Planar with cutting plane rough in, Done
Out by .080” .025”
Y axis Sprockets loose Tightened Done
Y Axis couplers slipping under heavy load or Tightened Done
Rapid start/stop. This situation allowed the gantry to get skewed, working
on a better solution for this issue.
Rotor Head Not Straight, Mounts Hand Cut Line Bored Done
Rotor Brackets Bottom, mount Holes stripped up size Done
Z carriage Loose, .020” plus Tighten Done
Z Axis Motor Mount bound Straighten Done
Z Axis Coupler Slips Tighten Done
Spindle Alignment Better from above work Shim or shave, TBD pending
Y Travel Binds, check alignment Adjust as needed Pending
X Travel Binds, check alignment Adjust as needed pending
Bed Rails Not co-planar Mill pending
Stepper motors Calibration is off pending
Ball Screw Mapping has never been done pending
Software limits have never been defined pending
Machine Zero Never been established Need add on switches Pending
Travel Limits Need to install travel limit switches TBD Pending
I was hoping to have the Table on already but I kept finding more things being loose, stripped and out of alignment I was un-able to make it happen. Please be patient, I guarantee you will pleased with how much more accurate the router cuts and performs. I am working on improving the reputability and reliability of a homemade CNC router, what a challenge!
When we are back up and ready to run I will be providing training on the table system, Mach3 software, work offsets and many other things.
