Problem with calibration

[m.marino]

Well further checking the lead screw seems to have developed a bit of a bend to it. Will check the bearing screw to be sure that is secure and not causing a problem on the free end. If it is the lead screw, any suggestions on a Marchant Dice 3 axis router for fixing the problem as this is really a bummer as need to get some cutting done yesterday for a client.

Well the cap screw was loose and decided to re-true the whole system. Which now has me able to run at 550mm/min on the long axis with an acceleration of 2.5 which at 1/8 stepping gives me pretty good accuracy. As it is going to have to grind a bit off the end of the x axis or double check it's cap screw as it is now binding against the stepper post. Man am I looking forward to the oldham clamps getting here.

Still would like in put as to why not able to hit anything above 550 without dropping steps and locking up with over rev's. Z is doing fine at 450mm/min which gives a really nice smooth movement up and down and more than enough control in steps. So figured a good bit of it out myself. Still would like to get it up to 850 or 1000mm/min movement only to allow a bit faster cutting speed and quicker movement between cutting points.
