I do not have a dial test indicator...maybe worth a trip to the store this weekend.

Was counting on the cncfusion setup to reduce backlash to a point I didn't need to worry about it.

Hey Michael

I'm using the circular pocket wizard out of Mach 3 for these test. I see no finish pass option but I've seen that in meshcam.

Endmill is 11.1125mm

I was trying to measure...

Worked on back lash and getting Mach 3 dialed in last night for around 3 hours.

I'm not sure if I have a problem or Im chasing the impossible...but If trying to cut a circular pocket for a bearing...

Michael..that worked..getting better results now.

I switched back to half steps and adjusted the motor tuning steps in Mach 3 from the calculated 78.75 to 80 and things seem better but not...

I see no way to secure the ball nut...it just drops in.....Did I miss something?

Fixed up the Z-axis last night. Fixed the bolt not being tight from column to cncfusion block and added the 6m x 20 bolts for the gibs..

My next issue is dealing with precision...things are not...

Ok so I created my first part last sunday...very cool to have this machine in my garage.

I decided I would tighten the 12mm bolt as well as try and perform a z axis gib mod. I bought some 6mm x 20...

Thanks for feedback Robert. I imagine the programming would be involved in order to insure safety...fun stuff to sift through though.

My backup plan is to hand edit the gcode once I'm happy with...

I was cutting my first part this weekend and I couldn't help but notice how slow things were moving because of the plunge rate.

Basically I set the plunge rate low because I was working with a...

Not a bad idea Chris..

Are you not using the spring? Or did you just have it disconnected for the picture?

Total newbie comment...

I understand stiffening will give you better precision when dealing with harder material or taking deep cuts.

Is there a reason to take deeper cuts at once other than...

Michael...thank for the info.

It has been grinding me that the 12mm bolt is not tight and I even felt some flex in the Z when changing directions. I'm either going to break down and buy the tool...

Bought the Grizzly mill about a year ago and its seen very light use mostly as a glorified drill press.

Last Thursday I received my probotix 3 axis kit and the cnc fusion x y and z kit.

I only...
