General Mach Discussion / Re: setup
« on: February 27, 2013, 07:30:08 PM »
I believe I have solved the problem. I uninstalled and  reinstalled mach3. Then input 20,000 steps into motor tuning. Then took sonicracings advice and set velocity and acceleration very low. I have some backlash, and have parts on the way for that. I made the first cut, and have minor issues.
I built my machine on a budget,and went over...oops. There is things i would have done different, but am satisfied for now.

Thanks for the support from evryone in this forum. You guys are great.

i just reloaded mach3. DRO seem to read correct now. not exactly, but looks to be only .100 of on y axis and .25 off on the x axis. the x axis is slaved. All the motor settings are the same. Z axis is only .005 off.

I will get my xml sent to you as soon as i can Hood. Thanks for all the help. I am new to this, but am confident I can overcome

With the dial indicator, with the motors set at 20,000 steps per inch, the axis will move .085

This should be an easy entry. The math is straight forward. Before i installed the acme thread, i bench tested for accuracy. 10 revs per inch. motors coupled direct...

i am following ya. when i input the 20,000 into my motor tuning, the DRO moves , but not correct. for instance, if i move x-axis 3 inches ,the DRO will read 20. As if the units were in mm instead of inches. Double checked that. The only way for me to get the DRO to read somewhat correct is to calibrate and allow it to change the motor setting to its new value.

i measure the movement with a dial indicator. if i calibrate the motor in the settings menu, it changes the steps to 150,000 steps per unit. the DRO seems to read correct. But doesnt seem right.

i can get good movement out of the motors,nice and smooth, when i put in 20000. but when i calibrate the axis in settings,it sets the steps per so much higher. if i calibrate again it stalls the motors and wont repeat the calibration. is there another way to calibrate the axis so the DRO's read correct? I have been watching videos and reading tutorials so much, i may be over thinking.

microstep is 10. steppers are 200 steps per rev. 1 to 1 gear ratio. and 10 tpi

I have my micro-stepping set at 10,200 steps per revolution on the motors, 1 to 1 for gear ratio, 10 revolution per unit.

hello,I need a little help....ok...a LOT of help. Doing the math for my steps per unit, I come up with 20000. But when I calibrate the axis, it changes it to like 150000. but if i set the motors to this 150,000 then the motors stall. why?
