I'm testing out TurboCNC and Mach1 on my retrofit Shoptask, both of which I thought generated the g-codes from my DXF file. I guess I am wrong and now I am confused as to what software I need. I can

The software I am trying in dos is deskncdos and cncpro. Neither can see the parallel port. Tried setting the port to standard bi directional in the bios with no effect. Thanks Dean

Hi, I am having trouble running my cnc control software in dos. I have a 1Ghz Toshiba Sat Pro laptop running Win98. I can run kellycam and master5 in windows but step rates are too slow. When I exit

Anyone ever use any Parker Acroloop products? I got a couple of these off ebay, which I believe have the 8 axis cards installed. Can drive servos or steppers I think. Anyway, the display is a touch

How does this stuff differ from the Moglice that was being discussed several months back? -- Jerry |The Philly resin is something like $65 for the small container and then |another $20 or so for the

Yup Tim, something like that. Fortunately a little goes a long way. And hopefully cheap compared to several ballnuts. I did talk to the Super alloy manager some. He said it ought to work pretty well

The Philly resin is something like $65 for the small container and then another $20 or so for the release spray if I remember correctly. If you go with it the release spray is a must as it controls

Does anybody have a ballpark price for that polymer resin? I'm picturing a little 12"x12" router with cast acme nuts and cast linear bushings... - Tom Scarince www.thsengineering.com

Hi Ray.We're looking at kluging a live tool on our top plate Hardinge retrofit,that could handle turning a woodruff key cutter -type tool(torque,RPM).Do you have any ideas about what size motors would

Well, I can try to explain the reason for preloading. We are all used to using lathes, mills, etc that have lots of slop in the leadscrews. We just machine in one direction to take it up. Like the

Jon, "Nook" brand ball screw tolerance is about +/- .005 per foot. I allow for any variance with the CNC control settings and CNC program. Good enough for my CNC hobby mill. Wayne nuts, he screws

Mark Taft wrote: Read more closely, and look at the pictures. He isn't making ball nuts, he is assembling 2 Thompson single-row ball nuts on one screw, with a preloading device, to eliminate backlash.

[Cross post from Sherline group] As a way of documenting what I am learning as well as to say "Thanks" to those who are helping me to learn, I am working on providing some web-based tutorials on how

I found this one on the Web: http://www.mmanrow.20m.com/anti_backlash_nuts.htm I made a set from my own design and they work fine. Wayne

I turned down the speeds for accleration and such. Motors do not trip the geckos now. Of course I have yet to install the motors onto the machine to induce a load upon them, so I hope they still work

Yes, you can put together your own system that is as good to much better for a lot less money. It is a very frequent topic on this list and was discussed a lot just last week. Take a dive into the

Les, I hadn't even thought of using the ballscrew material with the polymer nut. I know that you can buy the screw material by the inch, from McMaster-Carr, but other than it being a new screw, would

Well, thanks for the complement Marv! Yes I think the cast polymer nut could work for acme as well as ballscrew material with the right o.d. clearance. Acme of course is not really the best for

Mark, It's funny you should ask, because I received this info, http://www.phillycast.com/products/inst-nut.pdf , from Les Watts, who seems always willing to share his vast knowledge. It was in
