Re: [Emc-users] Writeup on the CNC4PC MPG6 & C22 pendant
Jon, same question as Gene. Pix would be nice. I was thinking of buying one from stappenmotor.nl, they are charging 41 EUR ex. VAT for a 60mm encoder. I did not even think about one-handed operation, sound very usefull though. With a custom made (3D printed) housing from shapeways this will look as good (or better) as the mpg4 but with all the knobs and buttons at the right place for me.

I think you meant the white button, as I read in your original post. I found the same was true with my pendant. No apparent purpose in that. I need one hand to slip the gauge block under the tool, so I left it the way it was. I have 2 more unused wires in the cable so I could re-wire the white button for a momentary flood toggle or something.

[Emc-users] Writeup on the CNC4PC MPG6 & C22 pendant
Hi all, I finally got my CNC4PC 6 axis pendant set up to jog 3 axis, plus feed & spindle override in Emc2_2.3.0 / Axis. I am using the ilowpass filter to de- jitter the raw jog counts, and it is working quite well. This was not an entirely happy experience. The roughly $200.00 pendant & Parallel port interface is a Chinese product with Chinglish documentation and as such, requires a lot of reverse engineering to get things working. MP6 pendant: http://www.cnc4pc.com/Store/osc/product_info.php?cPath=40&products_id=162 The biggest issue is that although the web page above states that the pendant is a 6 axis pendant, it is not in fact what they say it is. The pendant that I received from them has only 4 axes that are wired, and 3 wires that are cut inside the pendant. The axis selector rotary switch has one extra position that can be jumper/soldered to one of the extra wires. I used the pink/black wire to do this. The "advertised" 6th axis position does not even exist on the rotary switch. After connecting the pink/black wire to the 5th axis output on the back of the rotary switch & checking with a continuity meter, I then moved that wire from pin 19 to pin 18 on the back of the DB25 connector attached to the end of the cable on the pendant and checked it again. I found that after plugging it into the C22 P-port adapter, the signal then appears on pin 12 of the Parallel port going into the computer. All the other signals appear as documented on the seller's web. C22 adapter: http://www.cnc4pc.com/Store/osc/product_info.php?cPath=40&products_id=159 The halui spindle/feed override function now includes an enable input which makes activating/deactivating those functions using the selector switch a no- brainer (thanks guys!). Here is a link to my pendant.hal file: http://www.foxpointdesign.com/cnc_stuff/pendant.hal You must add to the [HAL] section of your ini file this statement to enable the halui pins/functions: HALUI = halui and since my pendant.hal file is separate: HALFILE = pendant.hal To allow the overrides some range to function, I also add to the ini: MAX_FEED_OVERRIDE = 1.5 MAX_SPINDLE_OVERRIDE = 1.5 Any comments or corrections before adding to the wiki would be welcome!

And not one you should alter ;) It's normal for lathe tool offsets and tables to be in absolute native machine units and they should never alter. If you are setting a tool length, the tool table values ALWAYS stays in "radius" mode, NEVER "diameter" mode, the conversion is done in CAM and the program controller display. Anything other than that will royally screw up "diameter mode" CAM produced code.

I can display resolutions higher that its native 800x600 resolution but they are not always acceptable.

Re: [Emc-users] Switching to Vesa Driver
I'm a UNIX guy and actually do not use spaces in anything. But if I have an input field, then I rely on the validation of the input. Stepconf allows the space in a profile name but subsequently fails to fix that up or reject it for later use as filename. I always found VMS to be the simplest OS. Also very stable. We had a server problem with a memory leak. No sources... so no way to fix that. We used a cheap electrical timer which pulled the plug every morning at 2am and restored power at 2:30. Over 5 years there has been no problem with that. Then the box became obsolete. I think they buried it next to it's trusty timer in the local landfill... sni good times Btw what happens when that dreaded 'unexpected realtime blabla' happens and it's ignored. Rough running? Steps missed? All seems to be running good now. My little Taig Mill runs WAY faster now without any hickups or rough running compared to the comparably crappy performance under Mach3. Really nice. Can't wait to confirm the moves with a micrometer and then cut something cool on it.

As for gap Pete will tell you that when it sounds like frying bacon it is just right. A few years ago Pete Gruendeman , gruendeman AT att.net, brought a sinker edm to fest. Nice RC unit including a C axis so he could thread. A 1/4-20 thread in a file is pretty cute. It used a custom program written in compiled Basic under DOS. The gap sensor was a couple couple of comparators. The Z was driven by a stepper/servo. He planned to use parallel springs to hang a small X/Y (+- 0.01) for orbiting. Don't know if he ever got it finished. Steve Stallings may know the status of this project.

With four times the losses of a 48v inverter, it has to run hotter. But I don't think I'm delivering any news there. :-) It won't take long to pay for a new one, just on the battery savings. > >[1] I'll heed your admonition about catastrophic capacitor failure. :-) > > Its not the caps that fail, its all the other stuff that can't take > the surges when the esr on them goes to hell. Ah, oh, hmmm ..., I'd better put together that little esr meter then, because I found a bank of 2700 µF 80v capacitors in a retired SMPS. I thought that if the esr is OK, I'll use them in the supply to drive at least one axis. I spent several hours last night, hunting the web for low esr electrolytics here in Australia, but found nothing over 470µF in 80v. There's 15,000 µF 63v, but using them at 50v seems cutting it too fine. (At Siemens we weren't allowed to use electrolytics above half their rated voltage, and 2/3 of rated temperature, IIRC.) Maybe I can find some in the US. (I don't think they're a good item to buy on ebay, though.)

I don't think I'd want to put $500 into it since edm can be done, although non-automatically for under a $100 bill, I've done it several times here. Last time I needed 4 holes in a 10" saw blade to mount it on my rotary table and use emc to sharpen it. Drill bits just bounced off its chrome plated side surfaces. I grabbed a caulking gun, the rim from a plastic spool of teflon tape, coated the rim with caulk, set it down on the saw blade & poured it full of kerosene. Ground on a length of 1/4 brass pipe in the mills chuck, hot on the blade mounted on wood. Supply is a pair of $7 36 volt transformers, secondaries in series feeding a full wave bridge, the bridge feeding through a 50 ohm 200 watt resistor, with a 10 uf paper capacitor as the discharge storage capacitor. Set z down till it gets real noisy and start the spindle at about 100 rpm, feed at about .015" minute. The kero will blacken rapidly, but you can hear the progress. For younger ears, a set of gun mufflers might be in order, that 10 uf is NOISY when it fires. Smaller cap would be nice and quieter but that is what was in the junk box at the Heskett Ranchette. As the blade was a thin kerf blade, about 6 or 7 minutes a hole. Nice, very neat holes that cleared a 1/4" bolt about .005". Did anyone ever come up with a method to automate the feed via emc for this? -- Cheers, Gene "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
