No, you wire the second motor to the A channel. You need a four channel driver. Then you slave A to X.

Ground the shield at the entrance to the chassis. I assume you have a foil shield, and you are talking about the bare wire that is placed in contact with the foil. You ground at the entrance.

The 2HP HF DC is a gem. Lots of woodworkers swear by it. Best bang for the buck in DC. You can find a coupon for it in Woodworking magazines for $139 or $149.

The stock filter on it isn't good...

Ditto on the cross dowels.

Confirmat is the right screw, but be aware they use a special, expensive drill bit. A good source is Woodworkers Hardware:

The duct is nice, but I'm old school.

The way I learned this stuff is to follow a few rules:
1. Separate high voltage from low voltage
2. Be consistent about ins and outs - in from the left, out...

The M12VC comes with 1/4 and 1/2" collets in some kits. You can get 1/8", 1/4" and 1/2" collets from Precisebits and GP Collets.

The M12VC is a smaller router than the M12V (which currently is...

Dunno, it was significant drag in mine (alignment maybe). He didn't drop the price, so, yeah, it saved him some bucks.

Less drag on the motor. Easier to align. Fewer parts.

Are you talking about the lower bearing on the Z axis?
Don't need it. Works better without it. Did you see the video he has on assembling the Z?

I used chain from Ugracnc. They have a variety of sizes. The smaller ones don't open, the larger ones do. The description says whether it does or doesn't, but it's not particularly obvious. I...

The 2HP HF dust collector is considered one of the best HF gems. You buy it on sale, with the coupon for $130 or so. The filter needs to be upgraded. If you cut a lot of wood or MDF, you want a .5...

You can make the base out of cheap wood if you want to trade sweat equity for cost and you have a table saw and a bunch of clamps. Find a lumber yard that has real Southern Yellow Pine (SYP). SYP is...

Your budget is too small unless you want a toy.

A basic set of motors, drive electronics and power supply is going to cost you about $400.
The mechanics for a small gantry in MDF, which is about...

You aren't talking about the small movement of the hook along the length of the blade, right? That's the way it's designed to work. When you take an inside measurement, the hook is pressed in...

I did not have that problem on my FLA-300. I was always able to insert the wrench in the access hole and reach the BHCS.

I think your answer is "tool size".

I'm guessing you have a 1/8" bit.

You poke the tool down. You have a 1/8 hole. You move up 1", move right, move down,move left and retract. The size of...

Don't have any direct experience with that BoB, but usually, if that's what you see, you connect a positive voltage, Euro3D says +12, through a resistor, in this case something like 330 ohms (not at...

Don't bother shielding the power cable to the router.

If you are having a really serious noise issue, sometimes shielding the source of the noise can help, but usually you shield the part that is...

If you have a positive "Start" button that must be pressed before any restart could occur after E-Stop, then a momentary contact E-Start is fine. Presumably you have to press START for every...

In most systems, if you momentarily trigger E-Stop, it won't start again by itself, but this is a safety system. You want a mechanical interlock from restart, not just an electronic one.

He found and fixed his problem, but the cap is best placed as close to the input as possible, so at the BoB, not at the plate. Usually, for this kind of problem just a capacitor is all you need, but...

No they are not good for E-Stop. E-Stop is push on, push and twist off. When you activate E-Stop you want it to stay activated until you reset. It's not momentary contact. It is NC when...

Grounding is not all that hard, but there are a couple of places to go wrong.

The first "problem" you have is thinking that 110 ground and 220 ground are different. They better not be, or you...

I've gotten some chain from UGRAcnc.com. Pretty decent both price and quality. The larger sizes open, the smaller ones don't.

Ya need two connections to get a circuit. The slab of aluminum has a wire to the input.
That's one connection.

The power for the Gecko is the 48 v supply, and you have it's ground and + (it's...

Those with small machines can use one input. This works because Mach will move one axis at a time when it homes, and so you only need one home. As a limit switch, you don't care WHICH axis hit a...

The green wire from the AC power cord and the V- from the power supply should be connected to the frame/enclosure at ONE PLACE. Usually, you put a stud at some nice place near where the AC cord...

22 shielded is ideal for inputs. No need for anything bigger.

About the only thing you can think about is that the most easily available shielded wire is foil shield. That's great for things...

Care to share the basic idea? I did assemble my FLA-300 so the spindle goes off the front edge of the table so I can cut dovetails vertical. It's an extra setup, and if there is an efficient way to...
