We don't offer those drive pullies with a 3/4" bore at the moment. We can supply them if you are willing to wait. If so, what is the pulley pitch, how many teeth and the width of the belt.

The eyebolts are used in the squaring of the machine. I would use a standard carpenters square and first run the end mill along the edge of the square to first make it parallel with the long axis. Then run the end mill along the other edge with the short axis and adjust the eye bolts and chain according to the angle that the machine is out of square.

Yes, we have the optional table for the blackToe, but we need to fabricate it, which only takes one day. We generally reserve one week for the total fabrication and packing of all parts.

1) Make sure to setup Primary partition:

Primary
Beginning of this space
Ext4
Mount point: /
and Swap partition:

Logical
Beginning of this space
Swap area using "Something Else"

2) get and install updates and upgrades

sudo apt-get update
sudo apt-get upgrade

3) get raid software

sudo apt-get update
sudo apt-get install mdadm

4) setup RAID

a) if raids haven't been setup:
sudo mdadm --create /dev/md0 --chunk=256 --level=0 --raid-devices=2 /dev/sda /dev/sdb

b) if raids are setup, but just have to be reassembled:
sudo mdadm --assemble /dev/md0 /dev/sda /dev/sdb

or

mdadm --assemble --scan

I like to use a 3/8" drill bit to create the holes on a table to mount the rails to give the rails a bit of wiggle room to adjust the alignment of the rail.

If the VFD is presenting an ER 4 error, the VFD is most likely damaged. The VFD will either need to be serviced or you will need to purchase another VFD. The latter is probably the less expensive option, unfortunately.

The length of time it will take to build a CNC machine kit is not an easy answer. There may be a wide array of circumstances that limit a persons abilities to build the cnc machine kit in an efficient timeframe; however, if you have moderate dexterity and moderately mechanically inclined, you should have no problem building one of our machines within one weekend if the project has very little downtime.

The blackfoot requires a total of 50 feet of cable.

The X axis needs 15 feet
The Y axis needs 17 feet
and the Z-axis needs 18 feet

These are 20 gauge 4 conductor cable.

The wire that we sell for the limit switch wiring is here: https://www.buildyourcnc.com/item/3d-printer-component-cnc-electronicsandmotors-cable-wire-3-conductor-22-awg-wrcon-cablewire3conductor22awg

This is shielded cable to make sure there isn't any external interference with sensitive components and long wires associated with limit switches. This is necessary due to the interference caused by the motors on a CNC router and the milling process.

Additional Information:
So unshielded is cool. That's what I was curious about. Cheers.

Additional Information:
Absolutely. It's really the only type of cable I would recommend for connecting limit switches.

Yes, this is a must. You can attach the spoil board on the machine with screws, or you can setup a clamping system. We just screw it down.
