G-Code, CAD, and CAM discussions / strange circle cutting

« on: August 09, 2012, 08:36:34 PM »

hello, i'm kind of new to this machinning with cnc.

i recently converted my grizzle 8086 mill to cnc using hass plans, using a c11 driver and stepper motors.

i have cut a few simpple things with good results, they were basicly straight cuts in both x and y direction.  did 2 text cuts as well that had some curved lines.

i am using solid works cad with the HSMXpress for poast code.

i loaded the code cut the part and it came out the correct demintion in the general x axis direction. and as it got close to the max y direction things stoped moving???

i'm cutting a 5/8 hole.  in the x direction it measures 0.624 aproxamatly but yis 0.598 aprox. see the pic. 
any idea on what is happening???

i was running under the msm set cutting a circular pocket and had a lock on the z axis losen alowing the spindel to drop deeper into the work till it jamed and tiped the head befor i could hit the kill swich.

cleaned every thing up and checked out the drive and both x and y axis moved normal. happy camper at that. decided to check the mdi out to do a little job and wlow and behold NO MOVEMENT. went back and loded the original just bare moch3 files and no out put to the steppers?

thought i might have done something to mach files so uninstalled and tryed to reinstall barebone mach3 uninstalled every thing i could find with referance to mach3 first

but still no output??  i was getting out put under msm but not mach any ideas what is up and what do i need to do???

« on: February 27, 2012, 02:57:08 AM »

hi all,
i am a newby for sure... i am building a sieg 2x minimill into a cnc mill like hasses machine..
i decided to use mach3 and machstanderdmill software to run it.. i got mach installed and licences and also licesnced the mill wizard addons..
when i open up a wizard i see all the preloaded example inputs but i can not change any of them ...

don't know what i did wrong.. i know that the mach3 is working on my mill did a simple cut just to see it work. i have not set up the z axis yet as i was going to use the X/Y to cut the hardware for that axis.. but can't use any of the wizards

any help?
