Dealing with a mid-stop cut via Mach3, you will have to be careful if it is intentionally or unintentional. If you desire to stop your machine while in the middle of a cut be sure to stop it when the machine is moving in an upward motion on the z-axis and the X/Y-axis are stationary. Then you can choose the point (G-code) where the machine was left off and click on the Run from here button on the Program Run screen (left hand side) right above the Reset button.
(Make sure spindle/router is running before hand!)

Now if the machine stops unintentionally, and was moving in either the X/Y-axis, then it will be difficult to run the machine from the original point dealing with the coordinates might have been lost due the the machine continuing motion but via Mach3 the machine has stopped.

If this occurs to fight this issue before hand, is marking your home with the spindle/router to make a hole were your home is. Although moving it manually back to home the machine can be off by the smallest amount and could cause an inconsistent cut. If accuracy is something that can not be risked, then you can home the machine about a 1/4" or 1/2" down from the original home to start your cut on the same material but loosing that small piece.

Additional Information:
My typical go to solution is:

- Note the current g-code line where the machine stopped.
- If Mach3 errored and you cannot control the machine, Exit Mach3 - you may find that reset, stop does nothing to stop the spindle. When you exit mach3, the spindle will stop automatically.
- Restart Mach3. The DRO (Digital Readout) should show the correct coordinates where the machine position was before exiting Mach3.
- Scroll to the g-code line where the machine stopped. You may need to go a few lines prior to make sure you are not skipping any machining operations (which is why it is a good idea to learn the basics of g-code - don't worry, it's easy)
- Click on the "Run from Here" button.
- Mach3 will present you with a "Preparation Move" dialog box with the location that it will move to. If the coordinates shows a position that is into the material, make sure to specify a rapid height (clearance height) so the machine will move up first and then move to the location before moving down into the material. If the spindle is automatically controlled by Mach3, make sure to check the turn spindle on checkbox. If not, make sure the router or spindle is on before clicking OK.

My cnc router stops at gcode line 50,000 and cannot finish program. They are about 150k of lines total. I have Mach3 and have bought the additional line capability. Is 50,000 (or around that) the limit? Is Mach 4 hobby license better and in what ways? Thanks! Mike Huber

Additional Information:
If you have a license for Mach3, then you should be able to run g-code indefinitely. I think there is something else going on.

You can determine if the country is serviceable by:
- selecting the items you want to purchase on the website
- go to the cart (shopping cart top left of any webpage)
- log in, or register
- Enter the address and click on calculate shipping.

The webpage will return the direct rates and whether your area is serviced or not. Feel free to enter any address as long as you are able to receive the package from that address.

The shipping times are determined by the service you select in the shopping cart. If a machine is purchased, we generally have a one week lead time unless otherwise stated in the description of the machine's product page.

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.

WHAT CABLE LENGTHS SHOULD USE FOR THE BLACKFOOT CNC MACHINE

The greenBull can range is routing width sizes of 5 feet and 6 feet. The blackFoot has a 4 foot routing width.

Previous Solution:
The greenBull machine has a sturdier gantry than the blackFoot, so you can be more agressive with the cutting feedrate (cutting speed). The blackFoot is also a good machine, but it all comes down to the speed at which you want to produce the fabrication

The spindle is also highly recommended for it's quietness and easier cleanup (no fan blowing the dust in the air)

The greenBull can cut HDPE Seaboard, and other materials as well.

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, you can send your electronics to us for repair, or retrofit to work with either Mach3, Mach4 or LinuxCNC. You can send us an email at customerService@buildyourcnc.com to set up your appointment.

Some of the types of CNC electronics we will consider.

- We will work on electronics from other manufacturers as long as you are ok with the Mach3, Mach4 or LinuxCNC control software for your CNC machine or CNC router.

- We will repair or retrofit used CNC electronics.

- Some customers find that electronics are overwhelming to put together so we will finish these electronics wiring and assembly for you.

The cost for these includes labor cost for the time it takes to finish the CNC electronics repair or retrofit and for any parts that need to be replaced or added.
