			Goto: Avoid doing x/y and z gotos together. It's hard to visualize the path and your bit might crash into your work.

			Break up your part files into one bit per file. This makes it easier to troubleshoot each one.

			Best practice is to place your Z zero on top of your material. Also, if you can, place the Z-zero close to each cut so that you don't have to rely on the tram of the Shopbot to be perfect across a long distance - and it helps when your material is not perfectly flat.

	Q: How can I do inlay with the Shopbot?		Q: How can I do inlay with the Shopbot?
	:A: This is one of the great features of V-Carve software. Use a 90-degree V-bit to cut the positive image into the base, and use the same bit to cut the mirrored image protruding from the inlay wood. The depths of the two are set such that when the protruding part is set into the cavity, it forms an exact fit but with a ~.1” gap between the remaining flat sections of the pieces of wood. Glue is put in the recess and the parts are clamped together. After drying overnight, a bandsaw is used in the gap to separate the pieces, then the face is sanded. The result is a perfect inlay. There’s a good video showing the technique [https://youtu.be/d4992bEoNYI on YouTube]		:A: This is one of the great features of V-Carve software.

	~~Q: How do I run an air pass on the MN ShopBot?~~

	:A: If you use the special MakerNexus post processor it’s pretty hard to do an air pass. Two strategies come to mind, both requiring a second output of your shopbot code. First, lie to VCarve about the thickness of your material by an inch or two, (e.g. set it to be 2.25" thick when it is really .75" thick) and write a file using the zero-ing post processor. Second choice - create a separate output file (or files) and use the “no-zero” post processor, and manually set Z-zero to be somewhere above the actual surface of the material, run that file and when it is all good run the one with the z-zero code baked in. Anytime I post any tool paths out, I make a folder for auto zero and a folder for no zero. That way if I need to manually correct something on the fly or do an air pass, I just go to the no zero folder.

In that case, maybe import every tool library twice, renumber one of them, and then use the renumbered one on the ShopBot.)
			:The mechanism that causes this on the MakerNexus ShopBot is a bit involved, but the short version is that Fusion exports parts files that include the tool number (e.g., &Tool = 38) and a tool change command (macro C9) in the file header. The implementation of C9 on the MakerNexus ShopBot computer detects that there’s no ATC, and then it runs the code for the MTC (manual tool changer). The MTC code treats tools with numbers above 19 as belonging to an additional spindle that’s offset from the first. The exact interpretation of tool number is in a comment in MTC.sbp:
			<pre>
			'Head 1 (Z) tools are #1...#19
			'Head 2 (A) tools are #21...#29
			'Drill 1 (Z) tools are #31...#39
			'Drill 2 (Z) tools are #41...#49
			'Drill 3 (A) tools are #51...#59
			'Drill 4 (A) tools are #61...#69
			</pre>
			:For example, when using a tool numbered 38, the MTC code interpreted it as belonging to “Drill 1”. The MTC then reads the corresponding x,y offset defined in my_variables.sbc and applies the values as a temporary offset using the VO command. It looks like all the offsets are the same (x = 6 in., y = 0).
			:Unfortunately, the MTC code is the same code that displays the dialogs “Is tool number &tool in spindle?” and “Is Z axis zeroed?”, so it can’t just be disabled.
