Beautiful build. Amazing linear block plates.
6.8mh requires more voltage to be usable in the higher RPM ranges.
I see a difference between 42V and 48V, so I suggest playing with your rapids...
1/2 or 1/4. 80 steps/mm.
It goes on the back shaft and reduces motor resonance. YouTube explains it
6.8mH requires over 80V to run properly. Sell em and get something more around 3mH or less. Look at longs motors. I recommend a dual shaft too and...
I dont know what your motors or screws are, but you should be able to get 700rpm from the motor easily.
Thats 300ipm with a 10mm pitch screw.
Gta18 you have more research to do. Go find a whip calculator, get the mass of your gantry, then pick your motors. A 2005 screw isn't harder to...
Isnt a big mini mill just a CBeam machine?
I'm saying your third line should be two lines. Is your spindle controlled with PWM software? If it isnt, you can delete the S command.
It's right there. Pretty obvious issue.
f1000S16000 is your feed and spindle speed, something that doesn't have to be on every line.
you do NOT need two sets of linear rail on your Y axis! One pair is plenty for each side.
12mm screw is too small for 800mm. You will get...
Centered is always ideal. No reason not to....
Pshhh that's easy. 3 machines in and never changed.
universal Gcode Sender
Took some help and googling the right terms. Reading the manual helped. Ill post it all when the machine is done or someone asks.

Partially agree. I needed my 16mm because it was a 1000*1000 machine. 500mm is fine with the 8mm acme rod.
You cannot break the screws with the...
1) mount your end mounts in a movable spot, like with Tnuts to the rail. You do not want perfect center locations as they are not made concentric...
Wicked. I was always wondering how you could strongly offset the spindle head from the table. This is a good call. When will it be done?
Arduino + a huanyang. Will watch tonight
Yes but Savvas has done it, and the arduino has the pins needed to do so
Enable (pwm) and direction
Could you help me connect my VFD to an arduino?
