I did reboot the system and recheck the address reported by lspci, which was the same. That may not be very definitive, but at least serves as a data point.

[Emc-users] SCARA robot arm 3D printer

I ended up doing exactly what was suggested earlier in a previous thread, having MCodes call extrusion or heating, and that's about it. I didnt end up purchasing / going with the reprap/makerbot control boards as i didn't need the complexity. Overall it was simple but took many weeks to get up to speed, learn the innerworkings of emc2, and get stepgen to work with nontrivial kinematics. As the printer is a SCARA arm, the kinematics and setup make it quite a bit more difficult to calibrate, which also took a bit of time to work through.

This way, our industry wanted to become compatible with the British and American manufacturers for export And although we are using metric units here in Germany since the late 1880ies, we still buy heating and water pipes, fittings etc. in inch measures. When I sometimes bring my timber to be cut to our local sawmill, I specify 3/4 inch or one inch boards to be made out of it, although they will be measured as 20 or 25 mm boards. By the way, how come that in this mailing list everybody speaks in inches - you were writing about the metric revolution? Peter Peter, I was all on that hay ride for as long as it lasted. But when the gas stations that first put in pumps that measured liters made note that their monthly usage pumped into the customers tanks dropped to 10% because folks would just drive on down the street where they could buy gas by the gallon, a unit they had used all their lives, that effect brought the metric conversion of the US to a screeching halt. The rest of the system did go metric, but that today is entirely the effect of all the manufacturing having been exported. Had they put dual displays in the gas pumps for a few years, so folks could see at a glance what they were paying, they might have been able to let the gallons displays gradually fail, but some numbed nuts bean counter apparently wouldn't consider that idea. Instead, we took very careful aim and shot ourselves in both feet. I suspect real estate was also to be a holdout, hell, nobody around here has a clue what a hectar is, not even me. Dave schrieb: I was in engineering college from 76 to 81 and remember some discussion about this. Fortunately there was not too much to discuss as they had already decided that SI was the way to go and we had recently selected new books. At the same time the metric revolution was in full swing and they were changing out all of their machine tools in the school shop so they would all be metric. They were removing manual machines that were setup in inches and replacing them with machines setup in millimeters. Many of the machines were old so I was happy to see them go and be replaced with new machines. The school was very unique in that they encouraged students to use the machines and the facilities after hours. They had a shop supervisor who was paid to stay late most weekday nights. Even the garage was available, so we could put our cars on the lifts to do repairs and modifications. When I wasn't chasing girls, I lived at school. :-) Dave Some places decided that they could increase the effective price by 10-20% by going metric because the customer wasn't smart enough to do the conversion. Ha! That crashed quickly. So much for greed. I do believe that if we (US) had used metric on signs for the interstate hwy system and provided incentives for selling gasoline and diesel using liters we'd be metric today. Instead we have a mixed system where international companies, eg. aerospace and automotive are metric and almost everything else is english/imperial. I once had a GM manufactured car that was part metric and part english; now that was a pain. Logic and politics are rarely in the same room.

I think that Hectars are english also, as well as fathoms, etc. No, the Hectare is metric. An Are is an area 1km x 1km. A Hectare is 1/100 of that. So, a hectare is the area of a square 100m on a side. (1 million square metres to the Are, 10,000m^2 to the hectare.) Real estate is all about land records. Even in the relatively young US, land records now stretch back 300 years. No way anybody is going to be in a hurry to convert them to some newfangled system of units. GPS is no panacea. Almost no one's land deed, and certainly not mine, is described in terms that are easily confirmed by GPS survey, and even if I resurveyed my property I'd have to convince all my adjoining neighbors to go along as well as the county-record office before I could use the new measures in a sale of my property. Taint a cheap proposition even if everyone is being reasonable about it, and how often are people reasonable about land? Things are changing in land management , more because of the spread of GIS than anything else, but they are changing very slowly considering the technologies involved were settled decades ago. Standards, including units of measure, are intimately tied to commerce; hence my former employer, NIST, nee NBS, is in the US Department of Commerce. There have been least three official attempts at metrification in the USA in my lifetime, several of which NBS played a role in. None really took root (I exclude engineers and scientists) although many items on the shelves of stores I frequent are now marked in both English and metric units. Simplistically, I think it's because export of goods and services accounts for little more than 10 percent of our gross domestic product. That's a little tail on a big dog. This is a people problem that is not unique to the US. Look at the UK. Even though export accounts for some 30 percent of its GDP I know from firsthand experience that there is still a sizable resistance to SI. In neither the US nor the UK has legislation and its implementing regulations been completely successful. Lots of trade will give those who have the ability to change a monetary incentive to do so and lots of time will allow those who can't change to die away. Standards are intimately tied to agreements as well. http://en.wikipedia.org/wiki/Kilogram gives a nice sampling of the work that has been going into reaching international agreement on the redefinition of the kilogram. Regards, Kent I've had some discussions with county people about gps. Apparently in the Eastern states agreement is pretty good. A park district just acquired land adjacent to ours on Anderson Is. (south puget sound). The property line moved 6 to 10 feet east and this was supposedly done with high accuracy gps. There is a well established reference point less than a mi (as the crow flies) from the survey area so they had something decent to tie in to. I had to laugh at a friend of mine (his business was Ag) who was visiting relatives in Austria. I ask how he did with the metric system and he replied, Not bad ... as soon as I figured out that a Kg of cabbage was about this much (using hands to explain) I was OK.

It states that those power supplies can be controlled from a TTL PWM, so I assume that it will be easy to control from a standard parallel port with HAL and LinuxCNC. Is that correct? Has anyone set up a servo or stepper drive to adjust the laser's focal point? Seems easy enough, guess I am just wondering how to tie it into g-code. Before I embark on this adventure, I would appreciate any advice you might have. Thanks!
