Starting Mach4 with ESS plugged in, I get the message "CTftp::WakeUpClient - Error in recv"

Mach4 v4.2.0.5036
ESS plugin v285

Things I've tried:
System Configuration Utility - everything...

I am not able to find my Parametrics file for Cadkey 99. The missing file is Parametrics.cde. I think it was on a 2nd install disk - maybe it came with 98 or 97 . . . Anybody have this file?

Thx...

Mike,
I'm sorry, but I cannot follow your first paragraph. There is nothing happening that is not consistent with previous posts. The X axis was moved with inputs from Mach, and the result is the...

Board seems fine - both 5 volt lines are at reasonable voltages (5.00 & 4.85 from computer).

Signal output looks great.

1. No, it has not yet worked correctly.

2. Cables are very short - ethernet cables are 18" - all cables have been re-routed with no improvement.

3. X and Y axis' are creeping - Z is not. As...

Arturo,

What is the "guide" that you are referring to?

Good troubleshooting info Mike - still working through the list.

Hi Arturo, thanks for the reply.

Yes, this is that same board/project, and yes, I am just finally getting around to getting it working right (procrastination is one of my strengths). I have used...

It is not differential. This is a parallel port output from a PC. Connections are made via the breakout board and a secondary board that connects to the drives via short ethernet cables.

PC to...

My measuring test (described in the OP) indicated that it is wholly or substantially a unidirectional error.

I posted to the Mach forum to see if anyone has, or knows of a piece of communication...

Yes, it does use the same encoder

I have narrowed down a problem with my system to just a couple possible things, and the signal being output from Mach3 is looking more and more like the culprit. One way that comes to mind to...

My OP has a listing of the major components.

These encoders do NOT have differential outputs.

Cable from computer to BOB is about 2.5' long, shielded.

Definitely not anything slipping in...

I've got an error with a servo system that I have not been able to figure out. Everything works properly, except that the axis' slowly accumulate errors. I can run a routine that includes multiple...

You had my hopes up - unfortunately that wasn't the issue - nothing else set for those pins. Thanks for the reply.

I did a Boss retrofit. Intended to use a driver kit as you mention, but at the time (about 2 years ago) there wasn't anything available for such a big machine. Ended up doing it from scratch. Used...

Gene,
I am having a similar problem. I am not sure what you are referring to here when you discuss the cause of the problem. Do you remember enough to tell me more about what you mean by "outputs...

I'm a newbie at CNC machining, and I don't know whether there are any issues that will pop up down the road related to tool numbering.

I have plenty of tool-holders, so I will be able to leave...

I have a CNC4PC breakout board that includes a charge pump. I thought that I understood how the Charge Pump circuit was intended to be used, but evidently I don't.

I thought that the charge pump...

I've been watching boring heads on ebay, trying to find something much more accurate than the pretty typical model that I have. I have seen a number of this type head, but can't tell from the...

I am retrofitting a Bridgeport Boss mill with a PC controller. Unfortunately, I have only some of the wiring diagram sheets for this mill, and that does not include the oil pump.

The pump has 4...

Did you figure out what the problem was? I am having similar problems.

I have an R2E3 Boss machine with the head disassembled. Does anybody have a digitized assembly drawing of the head of this machine that you could send me, or is there such a thing posted somewhere?...

It seems that I have seen posts that talk about recommendations for a minimal installation of XP that excludes a lot of the un-needed components. Searching the forums here, I have not found...

Is there a schematic available somewhere for the "power dump" circuit ?

Expensive? Where are they used? Who supplies?

"which I would assume you figured to run at 60hz."
Would probably run at Fmax to minimize ripple.

"You would in all likely hood require high speed diodes for the bridge."
There are some big-ass...

DC Drive???

The only thing I'm familiar with along the lines of DC motor drives are servo drivers (which require a DC supply).

My thought was that If the DC supply in the VFD is fixed voltage, it would not likely be the voltage that I'm after (~140). On the other hand, if the controller is changing the output voltage by...
