To get anything from the USA would have cost several times its purchase price. I knew it would need some work here and there, but had no idea what was in store for me. I set myself up for thinking it would arrive with a broken laser tube. I knew I shouldnt get too excited and it would be more like an adventure than a plug n play tool. In retrospect, it was exactly that an adventure. But one that had different twists and turns than I had expected. The carton arrived unscathed. In fact, decent box within a box packing was provided. Inside however, the entire machine had almost completely shaken loose. Screws missing, others extremely loose, parts wandering around inside. It seems the Chinese havent yet discovered lock washers. The X axis arm was bent and the laser focusing head was dangling on with one screw, where it normally would have 3. Idm Crack Full Version Terbaru. The electronics were also a mess. Bare exposed wire and the optical limit sensor had broken its mount in two. The HV supply, like the laser head, holding on with just one screw where it should have 4. The AC inlet was cracked. The ground terminal missing. Wires on the ballast resistor completely loose. On and on. But. Below are the photos I sent to the seller. He refunded a partial amount that was enough to make it worthwhile to try and fix it. The water pump was a cheap Chinese go figure aquarium pump. It was missing a piece that was shown on its package and then proceeded to fall apart in my hands. Later, and only by searching the web, did I find that the unit was completely immersible, which solved some problems getting it flying after it was repaired. Its not a self priming pump. I ended up dropping it completely in large Sparkletts bottle and mixing in 5. The lenses and mirrors I had to clean and realign using a visible laser pointer. I wish it had its own beamsplitter and a locater visible laser, but it was a cheap unit and I knew sort of what I was getting. After several days of work on and off, the machine was ready to test. Low and behold, it worked. Or at least the laser worked and burned things placed under it. The limit sensor had to be adjusted, but that too was working soon afterwards. A few days later, I found an intermittent connection on the ballast resistor. This is a huge 5. K 1. 0 resistor. Probably about 5. I replaced it with a better one, though could only find ones that were 5. K. No huge problem, but I didnt expect to replace a simple resistor. I mounted the new one much better also. Old one plumbers tape and a piece of sheet rubber as an insulator. One screw. New one dual teflon coated holders held to the chassis with stainless screws and lockwashers. Better insulated connectors were also installed. The unit came with a dongle for its Moshi. Soft software. Upon some investigation, the dongle was a highly encrypted goody and I wouldnt be able to get around it. If youre asking yourself why on Earth require a dongle, its pretty simple when you consider that these makers arent so much concerned with others taking their software, as much as their software probably has bits of copyrighted code to begin with. Its a lot easier to steal someones rom based routines in a plotter or CNC machine than it is to write your own. Also, the CPU chip had its number completely sanded off. So the hardware and software shake hands and go to the dongle for verification. Fairly clever, but really kills your market of potential users. You MUST use their software to send data to the engraver. Even if you do the drawings in Photoshop or Autocad, they have to be imported into Moshisoft. And then. ouch. Even if its HPGL, which ruins the potential of the unit as a cutter. Now heres where things get interesting. Im an Apple guy. Ive had Apples since 1. Apple. I can find my way around a PC, but its not my favorite place to be. My current Apple is a 2. Intel Imac. The Moshisoft package expects a PC using LPT1 on its parallel port, Windows 2. XP, a USB buss, etc. Pretty standard if youre a PC user. But not for a Mac guy. So I thought to myself. A Mac has USB. I have a USB to parallel converter. I have Leopard, which features Bootcamp for running Windows. If I install Windows, maybe I can run this thing. I was able to get XP installed no small ordeal, btw and proceeded to test things. No go. At least using the USB to parallel converter I was using. It used the Prolific Technology PL2. I also ordered a different one advertised as using the ITE 8. PT PL2. 30. 5. Ive yet to see if a Mac can drive the thing. Regardless, at this point I took a huge left turn and decided to eliminate the Moshi electronics altogether. I bought a Roland DXY 8. Ebay. As a previous tech for Roland DG when these units first came out, I knew them very well. I stlll had an original DXY 8. My thought in all this was that I could replace the Moshisoft board with a Roland plotter board. Many were selling for cheap, but I noticed that one particular buyer was buying them all. They outbid me on several units, including a DXY9. I really wanted instead. The DXY 9. X and Y position. So with this other buyer, if I wanted one now, Id have to pay for it. This other buyer got their other wins at between 4. Therefore, I would need to pay much more than they were generally going for. I finally bid a very high price and got a DXY 8. Funny enough, a previous bid of mine on a 9. I ended up with both plotters. Amazingly one plotter had roms in it with my handwriting. I was the guy at Roland DG US who copied roms during those years. After the requisite investigation into motor resistances, pinouts and voltages needed, I decided to try the idea. That being, Lets drive the engraver with plotter electronics and see how that goes. I took the controller board to the 8. I added two small CPU fans in front of the hybrid BX 6. This is a custom Rohm device made just for Roland. Getting another would be almost impossible. Its a hermetically sealed device and no specs are available. While it was a complete guess as to whether it could drive the lasers motors, I didnt have much choice and so decided to keep it cool. I jumpered across the line filter for the 2. The power supply in the laser was clean enough, but only supplied 2. I needed as much juice as possible and the filter was an extra 13rd of an ohm. I added a cap to aid in stiffening this voltage. I also installed a fast blow 2 amp instead of their slo blo 1. I located a logic level point that changed for pen up and down. While it would seem the most logical place to grab that signal would be the plotters pen solenoid, the Roland uses chopped signals to relieve current draw and melted solenoids. I just wanted a hilo logic level and found one. Please note the relay below has since been replaced by a Vactrol. Slightly slower, but silent and no difference to engrave quality. I made a small board with an Aromat relay that switched from this pen uppen down logic level. One transistor to drive it and a diode to snub reverse currents and 1. K of input resistance and I was in business. This relay would short across the button provided to turn on the laser. I had no idea what voltages or signals the engraver had across this button, so decided a relay was the safest choice. These relays can switch extremely fast 3 5. Tutorials on using rea. Converter ultra fast image converter and editor. STL is an image format mainly used in a type 3. D printing technology called stereolithography, involving the production of three dimensional models, patterns and prototypes with polymers. The STL format was initially launched in the 1. D Systems, the first company to introduce and develop stereolithography, and it is nowadays supported by several computer aided design CAD programs. STL files store black and white 3. D objects, including only geometry data and no color, texture or other attributes usually featured by images created with CAD software. In comparison, Auto. CADs native interchange format DXF tends to have more popularity and offer more complex object descriptions than STL. DXF supports both 2. D and 3. D object rendering, and its features can vary according to the Auto. CAD release to which the format is associated. Continue reading.
