The Flexible Axis Revolving Tool-holder is a spring-loaded, ball bearing precision device which can apply variable force and cut or draw on uneven...
Thanks. This is my next hurdle... after truing all the axes. I was thinking of using aluminium similar to a scope mount
The Dude published a new build: Drag knife and pen holder which mounts in spindle collet. Read more about this build...
No just one opto sensor per axis. Maybe mechanical switches would be harder because you'd have to trip the switch from the back but those switches...
I have 1 switch per axis which acts as home+both limits. The optical microsensor switches get the machine positioned to within 0.001 mm. The...
Breech? Breach? I think the teflon is what matters... try this stuff...
That's easy with the OX. it has an open center so you can just do exactly like the guy in the video did and put the OX on legs to the height you like.
I think aluminum would have better tolerances than the steel angle that I have available to me. It's not as strong as steel but much lighter. I...
Mine is teflon grease. The bottle says "breach plug" grease. It really stinks too. I think that spray on silicone lube might work too but not sure.
I made mine from threaded rod. I think it's 7/16" with 16 threads/inch. I used 608 bearings and ground the ends to hold the bearings and fit the...
Hey if you want to make the OX plates you can just use a printer to print a template/guide and then stick it onto some aluminum, drill and cut. If...
Yes, but the shafts you can buy are always long. The motor bearings are weak and can't handle a side-load so we use the extra shaft to add...
Yep, with washers on both ends. I left off the lock-collar for now and will make a clamp the same way they make scope mounts... maybe 6 screws...
I tapped the ends of all the axes using my m5x8mm screws. It took about 15min per screw. I used vegetable oil for lubricant and dabbed off the...
Hey man it works. Got the spindle going and all 3 axes :) [media] It's kinda slow cause I have it all turned down for safety until I get the limit...
Thanks everyone for all the help. I now have a brushless DC motor spindle working. [media]
Almost there. [ATTACH]
The problem with that is you have the motor turning at 10k RPM so you must sample the port at 10k Hz which lowers the bandwidth by as much. I...
Doood, it works good enough to draw. :) [ATTACH]
Hey what about a motor out of an old treadmill for a lathe?
