Hi all,
A little background;-I have a no-name brand of CNC 2'X2'X4.5" router table made with:-Vexta PK266-02A step motors, 1.8 degree, 2A (one motor per axis)-Mechatronics Bi-Polar 3 axis micro step driver board. Initial run with Mach 3 program:-max velocity of motors was roughly 26 ipm -at any velocity in any axis, extremely rough movements, 2 axis movements were 2X as bad, to the point that it has worn out my comosite screw nuts after a mear 5 projects -Z axis would lose steps (simple 300 lines of code and Z would be up 0.060")-Roadrunner program would only cut 1/2 of it before the Z was above the piece and would be up about 0.150" at the end of the program
Things I have done: -Called company that made the table, they sent me a file called Easy3Mill.XML to be run inside the Mach3 program -Downloaded Easy3Mill.XML, NO CHANGE -Deleted the file Mach3Mill.XML, rebooted Mach 3 -Re-configured Port, Pins, motor tuning. Now I have max velocity of just over 60 ipm, very smooth operation in all 3 axis. I have run mutiple projects without issue using max velocity of 45 ipm on X and Y and 25 ipm on Z. BUT NOW IT"S BACK!!! Simple 28,000 lines of codes for a "V" router, after 17,000 lines the Z axis is up 0.060". Uninstalled Mach3 (not easy, over 60 files attached in various places after installation was done). Re-installed mach3, same issues as origanally, replaced Mach3Mill.XML with Easy3Mill.XML, worked ok, untill I reboot the program. Mach 3 rewrites the Mach3Mill.XML each time I reboot Tryed changing Kernal speed, using sherline mode, changed max velocity, changed voltage outputs to the motors from 2-4VDC.
My question is why does this Easy3Mill.XML file smooth out the movements, but still hasn't solved my Z axis issue?
? How do I solve my "losing Z axis steps"
Am I doing something wrong?
?
