General Mach Discussion / Troubles with PWM output Voltage
« on: December 15, 2013, 01:14:26 AM »
I'm having some trouble trying to get an PWM  output voltage through A gecko g540. Ive checked pinouts, pulleys, tried different htz settings in mach and Smooth stepper config. I'm just testing the output first to verify I can get 0-10v first before I go any further. I have SX3 converted machine and have installed the x4 spindle board which is setup for pwm and is optoisolated an would like to know if theres any suggestions out there on what I may be doing wrong. I did get 9.5 volts through the geckos vfd output with a 9 volt supply and believe its not the gecko. So I have to think its something in mach that I'm missing.

General Mach Discussion / Problems with probing with 4th axis NEED HELP
« on: November 18, 2012, 10:11:37 PM »
Just recently got my 4th axis (A) working and seems to be working good. It is setup to angular and every thing works. When I probed to the top of the part I got an error message saying " probe ignored activated at call for probe" in the the fault line and probe sat on part and did not retract like it normally does. Usually Z comes down on the part touches off and moves in the positive (up) direction hitting the limit switch and says z is now zeroed in english units. None of this happens but error shows up. Any help would be great. I dont believe i doubled up any of the pins. What can cause this. Worked fine up until the 4th axis setup.

General Mach Discussion / Mach turn issues, please help
« on: October 20, 2012, 12:59:31 PM »
Been using mach mill for years and was a bridgeport user for years, Finally got around to converting a lathe but never had a lot of experience with lathes.
Very confused on the setup within mach. Where is 0,0 dumb question I know.. Rapids are extremely fast which are nice but not necessary. Cant figure out why they wont change with ipm .  Another issue is tool post position . Id like the code from the wizards to set tool post position in front, closest to operator. I do not intend on using rear post any time soon. X start and x end seem to be very different from one wizard to another this is where i get very confused. Does this have anything to do with dia. mode. I am in diameter mode which i am also unsure of. I normally dont write my own codes but rely on cad/cam software, wizards and nfs in mill and would very much like the same aspects with turning. If I posted my xml file will this be helpful. Any help would be great.

General Mach Discussion / motors lose steps after vfd install
« on: July 18, 2012, 10:17:28 PM »
Finally got my vfd step/dir working and ran a code and noticed that stepper motors are now losing steps. At one moment they faulted out both digital drivers. Shut down system restarted and went into motor tuning changed a few numbers vel. accel and same problem occurs. Whats going on? Can there be some kind of noise or interference causing this issue . Kernal speed is set to 25000k . Maybe debounce setting increased not sure any help out there would be great.

General Mach Discussion / cnc4pc c35 bob w/spindle control question
« on: July 03, 2012, 11:35:33 PM »
Im currently converting  A 10x22 lathe and am using digital steppers 8056D and a c35 bob. My question is I would like to control spindle speed and also do some threading through Mach,
but am unsure on which board to use c6 variable speed control or c3 index pulse card with my Teco VFD EV series. And also what would be the best way to wire them to the vfd ??
Any help or suggestions would be greatly appreciated .

General Mach Discussion / mach turn for mill questions..?
« on: July 25, 2011, 01:55:00 AM »
I am currently trying to make mach turn run on my sx3 mill. Having a bit of trouble since I do not  understanding the axis configuration in mach. Is there i/o that i need to setup differently in the turn ports and pins . A little lost and just need some basics in the lathe and mach turn department. Ive operated a manual plenty of times but never a cnc unit. Any suggestions would be great thanks.

General Mach Discussion / Safe z moves question
« on: April 10, 2011, 10:51:29 PM »
I recently purchased the Newfangled wizzards and am having troubles with z moves .
When I post code and get sent to the run program, I press cycle start Z moves off of part to top of z and status replies with a "Safe Z moved Down to  Soft Limit Minimum" , I played with offsets g54 and g55 and still same response, What am I doing wrong??
