BobCad draws the crowd!

Hello everyone, my name is Keith and I run a part time sign business. I purchased a DynaCNC 48 x 48 router and had some difficulty settting it up and getting it running. Many thanks to Steve at Dynacnc. I am having trouble getting the outside of raised routed letters to have a smooth finish. No matter what tool step over it does not seem to help. I am machining MDF letters from 2.5" -5" letter height with a 1/4" flat end mill. I have played with the step over from 1/2 of the tool to less than 1/2 and I still have the small indentations of the 1/8" radius. Any help is greatly appreciated.
Thanks and I look forward to sharing ideas and problems. Mostly problems until I can somewhat master BobCad and BobArt ProX.
thanks
Keith

Selmac I don't know if this will work for you or not, but I had to delete the txt part of the extension and just leave the . otherwise my machine would't reconize it.

Are you solid machining these or are you profile milling? It sounds like you are doing this part as a solid. Let us know as this makes a big difference on the help you need.

I will be down that way in a few weeks if all goes well. I live in Bristol, TN. but I contract out program work on Jungner CNC grinders. I have a customer located there by the name of SC Tool Services. They sharpen and manufacture tooling for machining applications. They can make a drill cut better than factory (even the high cost ones).

I build four differnt machines. I use bobcad and mach2 but i never did find out how to use rapid moves G00. If i use G00 my steppers can,t handle the speed. Is there a place to cgange the speed of rapid moves? I tried tunning the steppers in mach2 but had no luck.
