Spray it on, let it sit, brush and wipe it off, repeat. Dawn dishwashing soap works well with kerosense. Buy big bottles of it from Sam's/Costco etc. It works best when things are warm of course. Aim a space heater at the machine for a while and get it up to 80-90 degrees then spray it on and things will go much faster. I've used that solution for years to clean up dirty engines. A cheap pump up tank sprayer such as used for weeds etc works fine.

To: emc-users@lists.sourceforge.net Message-ID: <551750c4.6010...@evanspt.com> Content-Type: text/plain; charset=utf-8; format=flowed I am looking for either some cool ideas or someone who would like to take a project of my (too full) hands. I just sold off my manual sinker EDM and acquired a CNC sinker. Along with the deal came an identical "parts machine". The folks told me that it was functional when they took it out of service, but over the years they have swapped out boards and other parts with the twin that they were still using. It is a mid-to-late 90's Charmilles Roboform 20. It does not have C axis or an electrode changer. A picture of this machine can be had by googling images for the model. I think my first choice would be to deal the machine to someone who would want to repurpose it and allow me to keep spares. I would like to keep boards, monitor, keyboard and touchpads, probably even the axis motors. I can probably do without the ballscrews, so if someone were looking for an XYZ platform it seems like it would be an opportunity. For this scenario I would let it go for very little, as it is currently residing under a tarp and partial overhang, blocking one garage door. (Assembled it is too tall to get inside.) It could be brought back to life as its original EDM, but I can't guarantee all of the parts are fully functional or even there. I imagine some of the boards were swapped and the faulty ones not fixed. It would likely get expensive. For those of you who may not know about EDMs, their travel resolutions are quite accurate, but they will not be built as heavily as a milling machine because they typically move slow and do not encounter cutting loads or resistance. With my overwhelmingly positive experience with my Linux CNC 4-axis creep-feed grinder, I am tempted to repurpose this myself. I would probably do this if I could visualize myself completing it into a laser engraver. Other ideas include perhaps a CMM or Laser Scanner. It would probably make a great 3D printer, or light milling/ engraving machine. I am hurting for space and I am not sure my enthusiasm or need for any of these is sufficient. Do any of you have any ideas to fire up my enthusiasm, or any interest in acquiring the machine? I live in Oregon. The unit is on a pallet and weighs around 2000 lb. I move things like this by renting a drop-bed trailer and rolling it on and off with a pallet jack. -- Andy Evans Evans Precision Tooling Incorporated 541.990.2122 ------------------------------ Message: 4 Date: Sat, 28 Mar 2015 22:53:53 -0500 From: Scott Salrin <scott.sal...@gmail.com> Subject: Re: [Emc-users] Smart little device for zeroing To: "Enhanced Machine Controller (EMC)" <emc-users@lists.sourceforge.net> Message-ID: <cal9+1fnsjx8cfi6qglgsm1zhlsxptb5vq1suugmgysw_kk6...@mail.gmail.com> Content-Type: text/plain; charset=UTF-8 Thanks again for the words of encouragement the other day, guys. I've been thinking, which has always been dangerous for me. I need to bounce my thoughts off of some smart people, to set me straight. First let be beg forgiveness if this is inappropriate, or if I pull this thread off topic... It seemed dead anyway. As I mentioned, I have not received the machine yet, so all of this is theory at this point. The router is a Probotix Nebula, and will come ready to make chips out of the crate, but I have a lot to learn in preparation and trying to figure it out on my own is starting to hurt. I am having a tool length switch installed and it will come configured with a tool changing routine. The routine is called by a o100 command. I am also having a 4th axis rotary installed. This is where I am confusing myself. I haven't purchased the cam yet, but do believe it will be vectric aspire. This means the the rotary work will have to be wrapped around I believe the x axis, in this case, at the post processor. I also want to use the makers guide featured in the attached video, foe most of my work, and will need to pull off all the custom buttons and code to make that happen. Am I correct in thinking that all the coding I'll need to do will be in absolute co-ordinates, and not affected by the gcode that is wrapped around the x axis. Like if I set the rotary to be say a G55 work co-ordinate, and run a wrapped gcode file that has tool changes in it, when a tool change routine is called the machine will go to the tool change position, wait for me, do the routine and go back to G55 and start running the wrapped code again? Or, is it going to sit there after the new tool length offset and spin the A axis instead of travelling back the the work offset origin? Here is a link to the code Probotix uses: http://www.probotix.com/wiki/index.php/Automatic_Tool_Length_Sensor I apologize for all the background, but don't know enough to know how much info you might need, or if you get these "newbie" questions all the time.

Will run a big ballnose down the center if it needs to be lower down. Of course that screw will need shortened a bunch. I plan to give it as much cross slide travel as I can. The other axis is a "vintage" Star ballscrew linear actuator made in 1997, inside a 2x2" aluminum extrusion with a block on one side. I'll mount that to the side of the bed with the block down (keep the chips out of the open side) and make a dead simple bracket to mount from the side of the block to the original apron mounting holes on the saddle. And it has motors, bleeping expensive Superior Electric Slo-Syn 200 step steppers. A NEMA 34 connected to the Star actuator direct drive with a Lovejoy and a NEMA 23 with a belt drive to the other axis. The builder for some reason put the large pulley on the motor. The table is HEAVY, made of nicely put together wood. It shall become the new seat upon which my PLM2000 mill will set, after removal of everything screwed down to its top. It looks deceptively weedy in the photos but it's around 4 feet tall. Took three people to get it into the truck and we had to tilt it up on one edge then down onto the tailgate to lift and slide it in. Cost? $300 cash money. :) Some of the other parts may migrate their way into a 3D printer I'm wanting to build. Need to do something with the 30 feet of 40x40mm aluminum t-slot extrusion and various corner plates and angle brackets I've been given. --- This email has been checked for viruses by Avast antivirus software. http://www.avast.com ------------------------------ ------------------------------------------------------------------------------ Dive into the World of Parallel Programming The Go Parallel Website, sponsored by Intel and developed in partnership with Slashdot Media, is your hub for all things parallel software development, from weekly thought leadership blogs to news, videos, case studies, tutorials and more.
