PoKeys / THREADIDNG ISSUES

« on: February 19, 2020, 02:09:30 PM »

So I made my machine cut a thread . I cut a 20 threads per inch. The problem is I had to change my motor tuning to run at .050 per inch the motion controller was feeding the machine to fast my acceleration was at 50 and it cut 5 threads per inch . Whats the deal .The motion controller sees the spindle speed .It knows the motor tuning .Why wont it feed correctly? I need some support please.

PoKeys / POKEYS57E THREADING ISSUES

« on: February 11, 2020, 09:13:08 AM »

So I have been battling threading problems for a while now .Original had a AC servo motor driving my spindle in step and direction . After much work I was told that Pokeys dose not support threading in step and direction and that I should re-wire my drive to run analog .Which I did now the machine will follow a lead, problem being the pitch is way off .I also cannot program in inch per rev. My z axis is calibrated .I checked last night a 3 inch move was 5 tenths out and the machines DRO was 3.00 .So if my z axis moves correctly why is my thread lead off ? Some one help please .

PoKeys / POKEYS 57E

« on: January 31, 2020, 08:13:02 AM »

So I recently found out that Pokeys 57e dose not support threading when using step and direction .I have an AC Servo motor to drive my spindle and have been going back and forth with the makers of the M16 Board and Pokeys and for a while They were saying my setup was no good had me change encoders ,change all my pulleys. Then I was told it wont work with a servo motor as a spindle .So now I wondering is it just my Lichuan AC servo spindle or all AC servo spindles that have this issue.

PoKeys / Pokeys57e & M-16 PROBLEMS

« on: December 02, 2019, 08:40:33 PM »

I have a cnc lathe controlled with a  M-16  with the Pokeys 57e .I am using a Lichuan AC servo and Lichuan B-2 drive to control my spindle .Currently I can not thread . I can control the the spindle speed and direction . I am using G76 for threading and once the machine gets to the second line of G76 all motion stops with no error codes. I do have an encoder connected and index is mapped in Mach4 .When I check the diagnostics page the light for index dose not blink .If I set index as active low light is on constantly and never blinks if I uncheck active low light never comes on .I really need some help to get this fixed .If someone has a m16 running an encoder can you please tell me if the index light blinks on the diagnostics page Thank you

PoKeys / 57e Thread Problem

« on: December 01, 2019, 10:06:11 AM »

I have a dyna myte DM-3000 Converted to run on Mach 4  .I am using a CNC4PC M-16 with a Pokeys57E .I am attempting to use a Lichuan AC Servo motor to drive my spindle and a Lichuan B-2 drive to power the 1.8 kw servo motor . I have changed all the pulleys so the spindle moves 1;1 of the drive motor . The Lichuan motor drives an idler shaft that drives the spindle shaft all have the same pulleys .The main spindle drives an encoder at 1;1 . I cant get the machine to thread,  it stops on the second line of G76 code .With no error message .I can call out a spindle speed and direction and the machine will run at programmed speed and direction  .Mach 4 will show the programmed speed . I have triple checked all my connections and settings and cant figure out whats wrong .I n Mach 4 I am using rigid taping . Please Can someone help me figure this out . Thank you for your help.
