Congrats Matthew , you're getting there . My rapids are set at 600 ipm x & y , z is 400 , my work/cut speed is set 350 ipm x & y , z is 250 (although I'll never cut at those speeds ) , the fastest I cut is when I surface my spoil board and I do that at 200 ipm , that's plenty fast enough for me . I'm not sure what accelerations settings are set to as my machine was set up in factory and I have not changed the settings , I'll have to look when I get a chance . Hope you get the spindle going soon . Glad you are getting good support from the manufacturer , I've read a little on that outfit on the CNCZone , and have seen some of their people even post responses there , looks like a good outfit . I had my machines control computer remoted into by CAMaster to activate my fast tool change feature and it was a pretty neat experience , I sat there on the phone with the tech and could hear him typing on his keyboard and watch my computer screen opening files and such and he even ran a test file remotely .
