General Mach Discussion / Re: V Carving Quality - possible problem on entry and exit points?
« on: August 04, 2017, 01:21:49 PM »
I have my problem fixed. Fortunately the Manufacturer Legacy CNC Machine called me and signed into my machine and could see pictures of the problems.
He walked me through procedures to adjust out backlash on my X and Y axis. This machine has Rack and Pinion X and Y.
On Z I have about .0035 backlash, but he didn't think that would be my problem. My Z is nut and screw type, don't know what the right terminology is for that.
He also had me flatten a board on x travel and then another board on y travel. We were both very happy with the tram results. Never perfect, but really good and also decided this was NOT my problem.
Last after this I had good improvement, but still some problems in the quality of letters. Then found that the one 60 degree bit I was using performed great when set at 65 degree and the other when set at 67 degrees. Interesting as I ran the program suggested by CNCNutz and I would say that test showed by bits close to 60 degrees. Interesting!
Thanks to everyone that had input and ideas.
