Never mind. I found that the motor coupling broke.
My Mini Mill suddenly started making oblong holes instead of round. I checked the x axis and the stepper motor has no holding strength with power...
I'll try to take some photos of my modifications this evening when I get home. I've also considered the hiwin style bearings and rails for the z...
I've modified my Mini Mill considerably. I added a 20x80 v slot extrusion to the c-beam column, added 3mm plate to both sides of the column &...
I still don't like the results. Maybe I'm just discovering the limits of the Mini Mill.
I did some checking and found that my anti-backlash nuts were a little loose. The y axis had the most play in it. I've yet to try milling...
I used a test dial indicator and move the y axis while the tip of the indicator traveled over the top of my spacer plate (i.e. spoil board) used...
I'm still trying to get it perfect, but front/back tilt is out no more than 0.001" - 0.002" checked after surfacing in the X direction. I'm going...
When said the front, I meant the vertical surface.
I'm still experimenting and getting used to my Mini Mill and learning how to set-up jobs going from Fusion 360 to actually machining pieces in...
Anyone have any suggestions for preventing hot aluminum chips from embedding themselves in the Xtreme Solid V wheels as they thrown from the bit?
Sonny, Using my MiniMill to make tools for my MiniMill hasn't gone so well for me yet. Three attempts at milling the fixed block have been...
Found a broken and shorted wire on a DIN connector I was using for my stepper motor leads into my box and I fixed it. All is well and working...
I have been using my MiniMill with a CNC xPRO V3 board successfully for the past several months without any problems. I recently hooked up an...
That is what I assumed, but I could not see a shim in the photos.
Sonny, In the photos, your vise appears to be mounted directly on the x-axis gantry plate of the MiniMill. On my MiniMill, the top of the gantry...
What's the best method to level the x axis gantry plate so that a dial indicator holds relatively steady (measuring vertical movement) when...
I discovered some play in the z axis that was contributing to the bits walking. I tightened things up a bit and everything looks great. Combined...
I made my own collet reducer last night with a piece of 0.016" aluminum sheet rolled around the 7/32" Cobalt steel drill bit. The my plunge rate...
I was referring to dual y-axis with lead screws for both. A motor would drive one with a belt between the motor driven lead screw and the other...
