General Mach Discussion / Mach3 going off course of cut
« on: December 09, 2006, 01:07:25 AM »
I drew a little part in auto cad and then sent it to Lcam..Set it all up..Looked good when it displayed..Then sent it to Mach 3..It looks good in the display..Mach will be cutting just fine and then all of a sudden it goes wildly off course..you can see the proper blue lines before and then the yellow cut course in the display just goes wildly off course,and it goes crazy with the speeds too!! The router itself goes with this crazy line forgetting about limits for speed too...What is going on here??  Michael

General Mach Discussion / About the Licence restrictions
« on: December 06, 2006, 07:35:52 PM »
I was wondering about the licence restrictions..If I have multiple computers at my shop ( two running the demo mode right now and another inside where it is warm and comfy),do I need to buy three licences?? or can I copy the one licence to use in all three machines..??...Michael

General Mach Discussion / 28800 to move one inch
« on: December 06, 2006, 07:18:15 PM »
Hi everyone!..I built the David Steele large table using the Xylotek board and the 269 steppers,using the Mach three software..The control board came set at 1/8th step...the router table uses 18 thread to the inch all thread...if the math is right,and I am sure it is because it moves exactly one inch when you jog it, that takes 28800 impulses to move one inch...8microsteps X 200 steps to revolve one revolution and then X 18 to move one inch...8X200X18=28800...Doesn't that seem awfully high??..moving the pin to the 1/4 or 1/2 step would really cut down on that number..Do i loose anything like torque or speed by changing this?

Also when it comes to tuning the acceleration..I am not after super speed on this table..Making the axes acceleration slope a gradual one instead of straight up,doesn't that help with the accuracy of the table,not missing steps or possible going off course of the cuts??
