General Mach Discussion / Mach 3 with 2 axis

« on: October 24, 2015, 05:00:26 PM »

Hello,

Does anyone know how I can set Mach 3 up to work with just 2 axis milling? Kind of like a prototrak. It will only be for a short time, until I get all the parts finished to get the z axis up and running.

Good afternoon I have a question i'm sure one of you can help me with. I am building a new cnc mill. It is servo based. Bare in mind all my previous experience is with steppers. I'm using amt102-v encoders. When setting these up in Mach3 how do I go about getting this setup correctly? I have the encoder set to 500ppr. They are connected to kelinginc 850 oz/in servo motors DC, I'm also using the DG4S 8020 sold by cnc4pc.

« on: January 13, 2010, 08:06:59 AM »

When running my machine and have the 4th axis running it runs in snail mode you can barely see the thing turn a job that says it only takes 6 min to run is taking well over an hour.

General Mach Discussion / Z Axis Problem Need Help Badly

« on: August 20, 2007, 06:04:47 PM »

I am having a problem with my Z axiz stalling. I just converted it to ball screw from the manual feed cnc. I didn't have any problems with the old setup as far as the axiz diving into metal without stalling but since the conversion i can't seem to get it to feed into the metal without stalling

My motor is a Sanyo Denki 720oz in motor 12-300VDC 6.0A with a 20 tooth gear on the motor and a 33 tooth gear on the ballscrew i have the steps per set at 16500 which is giving me the correct accuracy i just lost all sorts of torque what can i do to get this back

General Mach Discussion / Help with Motor tuning

« on: August 20, 2007, 09:17:06 AM »

I need some help getting my machine to cut parts accurately. I set my machine up the way i think that it should cut parts accurately by the manual but my parts are off by about .012 could some one please help me get this fixed as i am pretty new to this and am about to rip out my hair.

Machine specs:
I have a harbor Freight Big Green Round column Mill part number 33686
i Beliece the lead screw is 10 teeth per inch. I am using 1.65:1 Gear reduction

the stepper motors are 200 pulse i have Gecko G202 which i 10 Microstep drives

i believe it would be 200 * 10 = 2000

then i take my gear reduction
2000 * 1.65 = 3300
