Shrug... 'sounds to me like your Z is losing steps. A simple test would be reduce the Z-axis speed by at least half, and see what results you get then.

If it becomes 'accurate' then, you know...

Plus it also comes down to cost. Cambam is £99 one off and it is possible to write your own post processor.

A pneumatic cylinder comes with a manual? Did you mean "specifications sheet"? Or are you talking about a...

I agree, if your wires from relay to contactor are long or twisted, or run very close to other wiring. But if the leads are short, it doesn't matter much which end you put them on.

Since there...

The snubber circuitry is to reduce arcing erosion of the relay contacts. Any large electromagnet produces a strong "reverse EMF" pulse upon breaking the circuit. That pulse can often be of a much...

Two places I'd look are:
1) make sure you don't have "exact stop" active, or the machine will accelerate and decelerate for every line segment, and
2) see if you're using lines to approximate...

"OK, ensure a RC snubber across the AC coil."

Yep... or use an SSR with built-in snubber componentry.

"Are there any woods that are less prone to the fuzz?"

Basswood cuts pretty cleanly! <grin>

Sigh... ANY wood with strong fibers needs to at least be started with a down-cut spiral. After you get the surface cut, you may wish to switch to an up-cut bit to help clear chips.

Sigh.... I...

You might want to investigate CamBam. It has a large user community with tons (and TONS) of free support for new post-processors and all sorts of ingenious plugins and scripts available for free.

Fine... it was just a suggestion. You may ignore the fact that I've plated dried INSECTS by electroplating. But, then, that's impossible without vapor deposition plating... so I'll just go my merry...

You did not stipulate that it required to be mechanically robust. No... graphite IS fragile.

However, there are many conductive plastics which, with just a little 'seeding', will plate like...

Machinable Graphite is available in all sorts of stock sizes, is conductive, and is as easily plated as nearly any metal. Depending upon what you wish to plate onto it, it might require 'seeding',...

I sincerely apologize for not having responded sooner. I've been 'on the road' on client projects for a month, and not able to address this.

You cannot do that in EZlink, but you can re-define the port assignments in the Windows system hardware definitions (control panel, system). It's no big deal, easy to do.

I have an R2E4 on which I'd like to mount a small lathe chuck in the spindle.

The mill takes NMTB30/QC30 holders. I have plenty of end mill holders, but no shell mill adapters or threaded nose...

About a year after the last post -- yes, it's a thought.

But the Ajax system IS Mach3... ???

LLoyd

Yeah, Ig. I kind of figured that, because I didn't see no "stinkin'" big, honking reverser in the chuck. But I had to ask.

Tell me about your spindle motor. Did you keep the same...

Ig, the video doesn't show the spindle stopping and starting. Did you use a reversing tapping attachment, or did you stop the spindle and reverse-tap out of the holes?

Pity is, there are other competent CAM packages that will import from Alibre.

CAMBAM (CamBam CNC Software) is an example. I propelled a "junk" R2E4 from ground-up to fully-functional with a lot...

I have the DNC protocol, now. As time permits, I'll document it for you.

It's both as complex OR as simple as you'd like to make it. Bridgeport guys figured out some nice "hacks" to make it work...

EZLink isn't a protocol, it's a program that executes a communications protocol.

The rest isn't protocol, either -- it's configuration. ...

I have fully restored a Series I R2E4 to original electronics.

I have a need to use the "drip feed" method (DNC protocol) to work large programs.

I cannot find any documentation on the...

Mark,

Would it have been more constructive to tell him to eshew tapping under power, and hand-tap all his holes?

Some questions are legitimate. Some must be trolls.

When a guy asks you, "If...

Well, the implication was that he already HAD executed a tapping maneuver (um... half of one, actually <snicker>)

So, then: Since he doesn't understand the maneuvers necessary to back the tap...

I'm sorry. I thought you could just lock the spindle feed, tighten the locks on the knee, and force the whole table downwards by reversing a 4-40 tap. Alternatively, you could loosen up all the...

Reverse the spindle.

THAT's why I said "probably not suitable". I couldn't find any references to the IR-431, only the 4310. The 431 might be an NPN. Even the datasheet archives didn't have it.

It's ALSO probably not a suitable replacement for a Delco DTS-411. Here are the DTS-411 specs:
