You have to select the post processor. It's one of the configuration settings. There are two tabs at the top left, Drawing and System. Choose System and look down the tree for post processors. Choose...

The fix was not a classical current limiting resistor, but a control resistor that goes on the Gecko drive itself to just 'tell' the Gecko how much current to use. I looked at the drives closer and...

Figured it out. Gecko drive was running at 7A, it's max current spec. Using original 8A per phase steppers on Bridgeport. No problem, right? Wrong. The phases are each wired in series, which...

Thanks, guys. I did save a copy of the xml file, just in case. I merely downloaded the older version of Mach3 and installed it. The settings stayed in place automatically. I still have the same...

Smooth Stepper people suggested that the very latest Mach3 version x.066 was buggy with SS and I should downgrade one step to x.062 How do I do that without losing all of my setups in the various...

I think the config file for Smooth Stepper may not be optimized right. I'll try to post a screen shot. Turns out, I can't post. Screen shot is too big. Here are the salient parameters:

Controller...

Hi,
I will certainly try increasing the acceleration, but I think I already did that, with no improvement. The motors are hard wired into place and it's going to be hard to swap them. But since...

Hi,
Yes, it is happening during a dry run. Speeds are set to 20 "/min, accel is only 0.5. That should be plenty slow, shouldn't it? This problem does not happen if I jog. What is different about...

Hi,
Here's my setup: Bridgeport Series 1 cnc with Mach3, Geckos, original steppers, 70V supply, XP laptop, smooth stepper.

X and y work perfectly. I can do a job and note that the mechanical...

The seller cnctechzone has now gone completely dark. No communications. I sent the pendant back after he promised to refund money and that's the last I heard of him. No money. Buyer be REALLY aware.

The seller on ebay, Cnctechzone, has now ceased communicating with me about my return. He instructed me to return it, which I did. He said his engineer said there might be something wrong with the...

Hi,
I bought the XHC HB04 wireless pendant and it kinda works, but messes things up and I can't even get the ebay seller to respond to me. I can select Z axis, turn the knob, and get the X axis to...

I am about to throw this thing in the river. It gets confused. I stood there with the selector switch in the Z position and rotated the knob. The mill moved in the X direction. I kid you not. I had...

Even more news about it: I almost wrecked tools and parts because of this pendant! I was able to smack the machine's E-Stop in time. It just flat loses communications from time to time. It also...

Further use of it brings up a couple more problems. One, it just flat loses connection with the pc every once in a while, and you have to turn it off and then back on. Not a great feature. Two, they...

Well, it kinda works. I can get it to work, but then something happens and I end up in some undocumented mode and the manual doesn't address the other modes. For instance, I think I have it set up...

I gutted the machine pretty much like you do a fish. The transformer has been removed, so it's going to take some fiddling to test that. I was able to get a nice supply working again, so my supply...

That probably looks like a good solution. In sizing the power supply, I'm assuming 7A per phase, but I have two phases and that 7A is the rating for full step operation and in that mode, you always...

Hi,
No, I would use it on 3 phase. You can't use a 3 phase transformer on single phase, so far as I know. I'd put it back in, drive it with 3 phase power, and have 3 secondaries, each with a bridge...

I have the original 3 phase transformer and all the caps. There is some confusion out there about voltage. Some people refer to the rms voltage and some refer to the peak. If I run the standard 3...

Looking at HF Inverter Arc Welder - 80 Amp it says it has an open circuit voltage of 60 volts DC. Probably pulsed dc, but maybe not. Haven't looked at it on a scope. At any rate, it can put out...

Hmmm. Dunno. I have 5 messages in my inbox and can take up to 15 more. I have no restrictions on who I receive messages from. I'm flummoxed. Thanks for the link.

Thanks for the image. I don't have a blue wire, unless what looks like black to me is actually blue. I'll scrape the wire a little to see. AC motors create the fields that cause the rotor to follow...

It is new to me, and I have not set any voltages, but in terms of rpm, both single and three-phase motor speeds are determined by frequency, not voltage amplitude. That's how VFD drives work. The...

Everything seemed just fine. I can smoothly run rpm up and down, according to the dial. At all speeds under 2600 rpm, everything is just fine. However, the spindle itself maxes out at 2600 rpm and...

Thanks for the info. The speed changer and maybe brake were both added later, looks like. Hence, I have no docs on them to speak of. What I thought was just an inline filter turned out to be a...

I cannot locate any shop air pressure spec in any of my manuals for running the air brake and air speed changer. Apparently, those systems were optional and I didn't get those manuals. There is a...

Thanks to your info sheet, I adjusted the speed calibration bolt and it's spot on, now. The air motor will go one way but very reluctantly the other. Someone suggested a clogged air filter up there...

Good info. Thanks. I will have to modify it, though. I have the pneumatic speed control, btw. If I run it up to 4200 rpm, I'll be temporarily making the machine turn vastly faster than it's designed...

I just checked the spindle speed with 2 different digital tachometers and found 3251 rpm when the dial said 2200. I can see a little off, but 50% under-reporting? Is this normal or is there a way to...
