  1. Thanks @@lawrence_jeff E-mail sent
  2. @@lawrence_jeff, @@Rhys Hi guys and thanks for your work here. I know this is an old thread, but I've got a couple of question's and maybe you have the answers. I've used the supplied code for building an arcade control encoder for a raspberry pie arcade cabinet. The controls consist of 2 classic arcade style joysticks and 14 buttons, 1 joystick and 7 buttons for each player. I've written the device report descriptor to send 2 report ID's 1 for each player. When I plug the encoder into a windows machine it enumerates as a game pad with 2 controllers and everything works as expected. When I plug it into any of my linux machines including the rpi, the encoder enumerates and everything works except for the x- , y- axis values. My first question do you have any idea what values are expected for the -x, -y? In the device descriptor I've set logical minimum to -1, logical maximum to 1. I've set up my descriptor just like the example in the USB spec. Also did either of you use the gamepads discussed above in a linux based system? This is so close! I am using the Stellaris Launchpad for this. Any ideas are much appreciated. thanks Tim

  4. great job @@greeeg
  5. Great work thanks for sharing!!!
  6. Very cool project @@greeeg
  7. +1 looks great!
  8. skulled! good luck
  9. @@terjeio very nice, I like the pcb printer very much it's so ....cute. I would like to replicate it. Those actuators are not cheap though. Thanks for showing it off!
  10. This looks awesome @@terjeio. I really like diy CNC machines and would like to see your machine. I've machined a couple of 2 sided pcb's and had good luck re-aligning the 2nd side. When I layout the pcb I put in mounting holes for a small fixture I made. Then I bolt the pcb to the fixture run the 1st side, pull the fixture out flip the boad and reload the fixture. It works pretty well. 1st side 2nd side through holes line up pretty well! finished! heres a shot of my robot thanks for posting your project, you've got me thinking about putting a laser on my printer.
  11. Are you absolutely sure the lcd is connected correctly? Are you using the boosterpack @@Rei Vilo used? If not the connections could differ. From the looks of it @@Rei Vilo's library has been proved to work. I would re-check your connections. good luck!
  12. Great idea! Good thing your 1 left over pin was an ADC pin!
  13. Yea the Toyoda is an awesome machine and I wish it was mine. It's a pleasure to run it. It would not be effective as a laser cutter, and your right it wont corner that fast but, its amazing the speed at which some of , most of the newer large CNC's move and corner at.
  14. Oh Yes! We may have something in common there, machining metal while listening to metal! That would be great if the laser could handle it.
  15. Thanks for your opinion @@Fred! Here are a few more points to consider: Every industrial cnc I've seen seems to have ball screws, they are fast, and rigid. The Toyoda FA400 in the shop I work at rapids at about 2300 inch's per minute(59 MPM). This machine will easily take a .5" deep pass with a 1" cutter at 100 inchs a minute through 7075 aluminum all day long. I think that qualifies as rigid. Yes I know this example is not a good comparison to a small desktop machine, but just from the video and what the guy says in the video it would appear the ball screws are of good quality. You can also see in the video the round bearing rods seem pretty beefy. Yes it seems a laser would not need Z travel but... If you wanted to put a laser on your mill you could adjust your Z to focus the beam. As far as speed goes it all depends on the stepper drivers, the software running them, and if they have tuned the acceleration values to work with the ball screw. Why not throw a hot end in there and use it for printing if you could? You already have a precision positioning system. I dont see how the build area on this machine conflicts at all, its a desktop machine. I think with that being your end goal a large build area is a moot point. I also realize its been promised before but this one seems the closest so far. The only real con I see is using a router as a spindle, it's just so loud. I think the machine seems pretty nice, especially if your only going to machine plastic, and if in fact you could get 3 for 1 I think its a good bang for your buck. I can just about guarantee that this machine will take some fine tuning. I have yet to see one that doesnt. But once you get it dialed in it could be surprising. Am I going to put my money on it? No but if I was in the market and had a couple grand to throw at it I might consider it. Just my opinion.
